Latest / Uncomfortable Conversations with Josh Szeps / “The Climate Change Solution So Crazy it Just Might Work” with Quico Toro
Transcript
- 0:00Get a humans, welcome to the safe space for dangerous ideas.
- 0:07And let's be honest, however uncomfortable we say that we find conversations around
- 0:14climate chaos and renewables and nuclear and the future of the planet.
- 0:19The reality is that in general those conversations are taking place within a fairly comfortable
- 0:25elite consensus that says that the problem is there's too much carbon in the air.
- 0:30We have to stop producing so much carbon, we have to stop emitting it.
- 0:33The correct way to figure out how to do that is through international institutions
- 0:36like the United Nations, we have to electrify everything and embrace renewable energy.
- 0:41All well and good.
- 0:42There has always been a subset of cranks who want to have more uncomfortable conversations
- 0:47about this, about the possibility of geoengineering the planet so that we can mitigate the worst
- 0:53effects of climate chaos, whether or not we are reducing carbon emissions, there's carbon
- 0:59capture and storage, there's a whole bunch of hair-brained ideas and I usually don't want
- 1:03to give huge credence to anything that smells of denailing the underlying problem.
- 1:10Today's guest does not do that.
- 1:13He's a fascinating individual, his name is Kiko Toro, he's the director of climate repair
- 1:18for the Anthropocene Institute and he has an idea, an idea that could revolutionize
- 1:24the way that we think about climate change.
- 1:27Kiko joined me on a sub-stack live from where he lives in Tokyo, he's formally a journalist
- 1:32by training, he's written for foreign affairs and the Atlantic, he wrote the latitudes column
- 1:38in the New York Times and it was a global opinion columnist for the Washington Post, he's
- 1:41now a contributing editor for persuasion.
- 1:45He is from Venezuela, so I spend the first 5 or 10 minutes of this conversation just
- 1:49picking his mind about democracy and Venezuela's descent into dictatorship and any lessons
- 1:54that we might be able to learn from it, feel free to skip through that if that's not your
- 1:57cup of tea, but this becomes a fascinating conversation about what is and isn't possible
- 2:03in extracting carbon from the atmosphere and one extraordinary plan that Kiko's team
- 2:07is working on that might just be crazy enough to work.
- 2:11I hope you enjoy as much as I did the one I don't like, Kiko Tora.
- 2:21How did you get out of Venezuela, what made you decide that it was time to leave?
- 2:26Well, I actually left pretty early but like in 2003 I was already out but it was running
- 2:32a journalistic website about Venezuela, it's still around, it's called Caracas Chronicles
- 2:37from Canada for quite a long time and those exciting news from Caracas, we had journalists
- 2:45in like 5 in the city writing for us but it's just a dictatorship got more and more authoritarian
- 2:52over time, just became more and more dictatorial and at a certain point it just wasn't safe,
- 2:57like I just couldn't be sending kids to take chances going to protest that I wasn't taking
- 3:03and at some point we were having to count kids on the way back from protests at the end
- 3:09of each day during the hardcore protest years and one day they didn't all come back and
- 3:16then you're trying to figure out where one of your journalists is and of course in that
- 3:20kind of regime when somebody gets arrested they don't announce that they've arrested
- 3:23you right, this disappears.
- 3:27So terrible times trying to find out where our guy was, they took him to a torture center
- 3:34but they didn't torture him but it took many days to figure out that he was safe and to
- 3:40get him out and it just became really too much, it just became clear that it wasn't really
- 3:45possible to do journalism about Venezuela safely anymore so I stopped.
- 3:51Did you see that incredible Argentinian film this year about the dissident who was disappeared,
- 3:58it was a true story in Argentina, do you know what I'm talking about?
- 4:02It was great anyway, I think it was I think it was a nominee for our best foreign language
- 4:08film at the Academy Awards and yeah, chilling to see how just they're just an ordinary middle
- 4:14class family and all of a sudden there's a late night knock at the door and then he's
- 4:18gone for just months and months and it's absolutely horrible yes yeah yeah, do you have
- 4:26friends back there of course of course and finally my uncle my godfather who I love is older
- 4:35now and in Garagas and you know no it's gonna happen it's a terrible situation right can
- 4:42you explain the decline of that country to people who don't understand what went wrong?
- 4:47I mean they spent 20 years doing that it takes it takes a bit of time but in some ways
- 4:52it's not that difficult you get a very charismatic strongman takes power promises people that
- 5:00if they give him all the power and undo all the checks and balances and all the institutions
- 5:04that could that could limit him from doing something their lives would be better they believe
- 5:08him he concentrates power and once he has enough power it doesn't need them anymore and that's
- 5:13really the the story that we've been through so it's Democratic bike backsliding it's not
- 5:18just Venezuela we've seen things like that no in Hungary it seems something like that and then Turkey
- 5:24has seen this process like that too and certainly in what Russia we've seen things like that and
- 5:30how in the US you see things that have quite some similarities it's really freaky for me reading
- 5:36American news he says yeah I was gonna ask you about that is it reminiscent yeah yeah I mean
- 5:43especially things like these authoritarian regimes they often they say really really crazy things
- 5:50that they don't believe such as you know Donald Trump is the most physically fit president the
- 5:57United States has ever had they you know they say things like that that they know are not true
- 6:02but the purpose is that they become a loyalty test to see if you're you're willing to
- 6:07base yourself by saying something that is obviously nonsense but it just becomes a way of like
- 6:12proving that you're willing to humiliate yourself rather than then then go against the regime and
- 6:19that's something we signed Venezuela all the time when we see stories like that in the US now it
- 6:24really it creeps me out it's yeah and so one of the dynamics that is happening in America that a
- 6:30lot of non-Americans find baffling and a lot of Americans find baffling is that those loyalty
- 6:35tests have succeeded such that the legislative branch is now completely occupied on the conservative
- 6:41side of well don't even want to say conservative because they're not conservative on the right
- 6:44wing side of politics by people who are in perfect lockstep with the leader and are pledging their
- 6:51fieldy on all of these loyalty tests about the crowd size at his first inauguration or whether
- 6:56their 2020 election was stolen and so on do you have an explanation from your experience in
- 7:01Venezuela why the parliament becomes co-opted by the leader why doesn't parliament do its job
- 7:08I mean it it becomes a problem of of negative selection right so you're selecting for people
- 7:14willing to obey and and and in the US you saw this very explicitly who's selecting it's supposed
- 7:20to be citizens who are selecting it during the primary process and during the election exactly exactly
- 7:25but citizens are selecting for this or Republican primary voters indeed are selecting for this
- 7:30because if Trump attacked you you would lose your primary as I became very clear to Republican
- 7:35politicians that if they wanted to have a long career in politics they would have to do this this
- 7:39was a surprise of entry but yeah the underlying issue here is that you have a hardcore of highly
- 7:47ideological brainwash people willing to go along with this nonsense and it's it's just painful
- 7:53yes I saw it in Venezuela that you had large sections of the population that could see that this
- 7:58was a bus careening off of the cliff and but you're sort of stuck in the back and cannot get
- 8:04to the driver's seat yeah I thought we're gonna talk about something else we are we are we are
- 8:10but no no I'm sorry but this is just you know we just have conversations which go wherever
- 8:15my interests take me and I hadn't thought about this you don't have to answer these questions if
- 8:19you don't want to if it's too sort of triggering but I am intrigued like what were the underlying
- 8:24conditions in Venezuela that led to the majority of people being so ideological because in the
- 8:32states we can talk about social media we can talk about globalization the decline of manufacturing
- 8:37you know whatever explanations you might want to give a backlash against workness what was
- 8:42happening in Venezuela at the time that left people susceptible to a strong man okay so there's
- 8:48a difference between sort of the initial conditions I think the initial conditions are really mostly
- 8:53about unfulfilled expectations. Venezuela was one of the world's fastest growing economies if not
- 9:00the world's fastest growing economy between 1925 and 1975 and after the olatrice is that mechanism
- 9:08of middle-class formation kind of stopped and a lot of people who had grown up seen you know their
- 9:14parents soon better than their grandparents and expecting that kind of investment found themselves
- 9:18shut out of a middle-class lifestyle that bred a lot of frustration I think you can see something
- 9:23similar to that in the US with unfulfilled expectations but that's the thing that that's
- 9:29how to go and once it's going the process feeds on itself right because the the populist machine
- 9:35creates its own rhetoric and its own culture and then it's it's very difficult to to get it to
- 9:42stop I mean in Venezuela we spent 25 years trying to stop it and we I mean the reality is we fail
- 9:48a quarter of the country had to leave the Venezuelan diaspora is now huge and it's not just numerically
- 9:54huge is that it's the young people the people who have some get up and go the high-agency people
- 10:00the ambitious people are left and so who you have left in Venezuela it's older people sicker
- 10:06people are kids people who are really ended up becoming dependent on remittances from their
- 10:13relatives abroad and what do you make of the current conflict or blooming conflict or and
- 10:21you know aggression from the United States towards Venezuela I mean what can I tell you it's
- 10:28it's absolutely shocking is it's very plain to me that they're they don't then the US
- 10:34administration doesn't really have a plan different spokespeople seem to have like different goals
- 10:39is it's really about drug trafficking is this about regime change is this about democracy like
- 10:44Marco Rubio seems like as a Cuban-American started off on that side but it's very difficult to
- 10:49believe that the Trump administration is going to bring democracy anywhere so it's not clear what
- 10:56their goals are or what their endpoint is and and it's very easy for me to imagine a situation where
- 11:03you know you start a bombing campaign I didn't spend the so that this this meant to trigger some
- 11:08kind of uprising from the military but if you don't do this carefully that uprising you you
- 11:13might just be fleshing out fleshing out then the traitorous people are the non-reliable people
- 11:20that the regime is going to want to purge right so this is a high states and like highly delicate
- 11:26thing that you would want done by people who know exactly what they're doing and who are
- 11:31careful and thoughtful about this and I don't hear anyone accusing the Trump administration of
- 11:36being careful or comfortable well paid heads that I mean and Donald Trump surely you know
- 11:42masses of diplomacy right last question but then yeah just just just just to put a presentation of
- 11:48that if you are a lieutenant lieutenant colonel in the business just in light of America every
- 11:54military revolt is junior officer sort of frustrating it's never the generals as always
- 11:58sitting your officers very junior officer who's frustrated with Meludo and wanting to see
- 12:03the back of him and you see the America's doing this well do you trust this administration
- 12:09enough to put your literal life on the line because if this goes badly you will end up in a dungeon
- 12:13they will torture and you will die right do you have enough confidence in them they are in the
- 12:18take a risk on these guys I don't think so I don't uh lastly is there were there any off ramps
- 12:29that were not taken in Venezuela that in hindsight you would recommend that we be mindful of in
- 12:35this situation that Americans be mindful of levers that we could be pulling that we're not pulling
- 12:41that if you'd pulled in Venezuela during its descent into dictatorship things could have gone
- 12:46differently I mean we I could spend a very long time talking about that it was always difficult
- 12:53in Venezuela to get enough consensus around one theory of change for how we would get the regime
- 13:00to to to alter its behavior or to let go so that the opposition was always quite disparate and
- 13:07like not really united and that really made it difficult for us to to be as effective as we might
- 13:13have been like if everyone had decided on the hardcore resistance grab some guns get to the hills
- 13:20strategy that might have worked ain't everybody had agreed on their peaceful resistance go to
- 13:24elections um resist that way that might have helped but what really didn't help us so we kind of had
- 13:30both and we didn't really have a way of uniting an approach to pushing packing us a regime and that
- 13:37well fortunately the Democrats are perfectly united so there's no problem there
- 13:41I say with a hint of irony um okay climate change the let I read your piece which is entitled what
- 13:52we're doing for the climate won't work here's what will um the you make the point that there
- 13:58are certain zombie paradigms on issues like climate change that stay dominant because people control
- 14:06the terms of the debate and define what isn't isn't acceptable to be to being said uh any pushback
- 14:12that I give you here is definitely not coming from my attempting to enforce a dominant paradigm
- 14:16because I agree with you on that the name of the show is uncomfortable conversation so I think we
- 14:20should be able to talk about everything and certainly scientists should study everything um including
- 14:27geoengineering and you know we'll get into all of the possible solutions to climate change
- 14:32but you also write that the current mantra of climate activists which is that we should electrify
- 14:39everything and embrace renewables is obviously not working because emissions keep rising
- 14:45every year at a faster and faster rate but my bullshit detector goes off there and I think but
- 14:51that's because we're not really implementing we're not electrifying everything and we're not
- 14:55embracing renewables really not to the extent that you know energy engineers say that we should
- 15:03be so why is that not a straw man well I think we need to think about the energy mix in a society
- 15:13not as something that uh somebody in a controlling room at the head of the state gets to like push
- 15:18button and decide it's it's the outcome of a series of dynamic processes where there are thousands
- 15:24and actually millions of decision makers deciding how they're going to power their houses how they're
- 15:28going to power uh their cars how who they're going to elect to congress or to parliament to to make
- 15:34these key decisions right and so that is quite a complex system and that you know you put all those
- 15:39inputs into the system and on the other end that's yours of decisions are made on the other end you
- 15:43get a certain number of tons of carbon dioxide being pumped into the atmosphere what we have now
- 15:50conclusively seen after 30 years after the original um United Nations framework convention and
- 15:56climate change was was agreed was that the outcome of those cumulative millions of decisions
- 16:03is more and more carbon dioxide every year we wish that it wasn't we wish that there was some
- 16:07lever that we could pull that would make that difference but that is obviously not the case
- 16:11if it was the case it would have happened already right so this moral situation this idea that
- 16:17if you feel bad enough about it or if we'd like posting of things on on Facebook or if we are
- 16:22like more virtuous that the outcome the equilibrium outcome of all those decisions is going to change
- 16:27seems to me like obvious lunacy and it is because in part but is killer okay yes no sorry I was just
- 16:35going to say isn't that a collective action problem that would apply to any solution including
- 16:40the solutions of geoengineering I mean we have failed to do there are some very simple things that
- 16:45we know we could do to dramatically reduce carbon and we have known for 30 years we could put a
- 16:50price on carbon the simplest way would be a carbon tax we could subsidize you know in jurisdictions
- 16:56which subsidize rooftop solar and make it easy to get permits for rooftop solar like Australia
- 17:01there's the highest uptake of rooftop rooftop solar in the world you could subsidize you know
- 17:07home batteries and have interest free government loans for them and you could you know you could
- 17:12facilitate the transition in ways that governments have refused to do partly because there's a lot
- 17:18of money in fossil fuels and those lobbyists give lots of money and people haven't quite gotten
- 17:23on the same page about what needs to be done and but all of the all of the reasons why the big
- 17:28levers aren't being pulled would it strike it strikes me would apply to any alternative solution
- 17:34I know they destroyed as well but I mean there are a couple there are a couple of things to
- 17:38start it out with the right framework which is that this is a collective action problem right if
- 17:42you had the world government if you had a way of like instituting decisions at the global scale
- 17:48then yes the carbon carbon price would absolutely solve the problem but for that you would need a
- 17:53world government which we don't have in the absence of a world government where you have this
- 17:57piecemeal decision making such a you can institute a carbon price in the European Union or in
- 18:03Japan or wherever it is but other countries are not going to do that and because we have an
- 18:08internet economy what you end up seeing is production moving to the jurisdictions where it's
- 18:14still cheaper to to pollute right and so why are carbon emissions still rising well it's not
- 18:20because the developed countries the countries where there's some massive of voters are actually
- 18:25concerned for a far enough along the mass low pyramid of needs care about this stuff it's not
- 18:30because they're not doing something they are like in the developed countries emissions are falling
- 18:34slowly but they are falling but for every one ton of carbon dioxide that developed countries
- 18:39have stopped putting in the atmosphere developing countries have added five right because they have
- 18:44the political economy decisions in those developing countries the pressures on the decision makers
- 18:49are very very different right particularly out of those five about four from from China so we
- 18:55to have a moment of sanity of realizing that we can control what we can control but there is
- 19:00no world government we cannot have to China in the in Indonesia uh Brazil South Africa into into
- 19:08having different political economies than they have they you know those decision making processes
- 19:14are what they are and we've seen what the equilibrium outcome of those processes is and
- 19:18is rising emissions so I just think 30 years after the original rear summit we should at least have
- 19:27the presence of mind of realizing that doubling down on a new NF triple C project that has already
- 19:33failed and that will continue to fail is simply wasting time and that we need to be doing something
- 19:39quite different and we need to be looking at solutions that in fact don't face those same kind
- 19:44of action what's NF triple C United Nations framework conversion for climate change all this
- 19:51cops right these are the talkfests that we do every year where we try to get towards a I mean
- 19:56just to push back on what maybe a straw man in that we would need a world government to implement
- 20:01a carbon tax you know we got rid of chlorofluora carbons to save the ozone layer we got rid of
- 20:07whaling uh you know we got agreement on a nuclear weapons framework that works has been working
- 20:13okay up until recently perhaps um there are all kinds of ways that we can come together
- 20:19if that if parties are coming in a sense of goodwill and compromise like if it's a constant
- 20:27low it's a constant low the point is that you can get rid of chlorofluora carbons
- 20:32rel it it's chlorofluora carbons I don't know how you say that um rel it's chlorofluora carbons and chlorofluora
- 20:38carbons yeah uh those are you you connect and there were technologically feasible solutions and
- 20:45alternatives to that to those that that didn't put a giant hole in your budget if you're the
- 20:50finance minister of Indonesia or or of China which are where they actually relevant decision
- 20:56makers here and not whatever corporation in uh the United States or whatever municipal or
- 21:02or national government in in Australia or or in Japan you're talking okay so um so the
- 21:08the problem is that you know when you're dealing with carbon dioxide you're dealing with combustion
- 21:12and combustion is at the center of so much of what we do right so so we are told that there are
- 21:19these easy costless solutions but it's obviously not true if it was true that um renewables were
- 21:26just a cheaper better simpler way of of powering societies than than fossil fuels you would need
- 21:34subsidies for them you know they they Indonesia's and the militias and the brisels of the world would
- 21:39be rushing to to adopt these solutions simply to cut costs the reality is that that is not happening
- 21:45because these these technologies have fundamental limitations to how large a portion of the grid
- 21:52they can take up because or weather dependent because they depend on expensive batteries for a
- 21:56series of reasons and so that entire way of thinking about the problem to me is is a data and then
- 22:05it's difficult because you do have this United Nations system you have chief sustainability officers
- 22:12in most large companies in the west now you have a cadre of people you have millions of people
- 22:17who live in the sustainability industry and in this UN framework and that's how they've
- 22:23built their careers that's how they've been trained to think about it and there's this inertia
- 22:28towards continuing to try to deal with these problems through these obviously limited solutions
- 22:35that that blinkers us that keeps the the overton window of possible solutions quite narrow
- 22:42and that excludes from from the conversation other responses that I think technically just seem
- 22:48much more promised so the the resistance that the the the the the steel manning of the resistance
- 22:55to considering those other options which will get to in a second yes the the straw man version
- 23:02of the opposition to your point of view is that people have vested interests in their own way
- 23:07of doing things and it obviously hasn't worked the steel man version is at some point in
- 23:14the future we're going to have to have a zero carbon economy regardless of what hacks we might
- 23:20be able to undertake in the short term to mitigate the effects of climate change so we're all going
- 23:26to have to get on the same page about this somehow in some way when I hear conservatives or
- 23:36right wingers talk about how well really the most of the growth in carbon emissions is coming
- 23:41from the developing world so anything we do is just shooting ourselves in the foot in Australia or
- 23:46the UK or the United States because we are a vanishingly small proportion of the growth in carbon
- 23:53emissions anyway and you can't expect poor people to care about the environment because they have
- 23:58to care about where how to put food on their table I hear buck passing and an unwillingness to
- 24:05step up and be the bigger party and have the moral credibility to construct a framework which is
- 24:12likely to get buy-in from developing countries because no developing country is going to make any
- 24:17sacrifice if Australia and the UK and the US and the EU continue to belch out as much as they want
- 24:24to the point of a country like Australia for example you know putting itself on a path towards
- 24:31zero carbon or towards renewables is not that our 2% of global emissions is going to make a
- 24:36difference it's that it gives us the credibility to go to international conferences and say we're
- 24:43tightening our belts we're copying a bit of pain here's a framework in which you guys can also
- 24:47copy a bit of pain and will help you out in any way we can to transition towards that future
- 24:54why is your position not just a hand waving like let's forget about having to make difficult
- 24:59sacrifices because we're not the ones to blame they are no no it's a look already this blame
- 25:07firmware to me is meaningless you're proposing a world where when the finance minister of Malaysia
- 25:16sits on with the energy minister of Malaysia and with the industrial industry interest in Malaysia
- 25:21and with politicians who will go to election and who have to respond to I electorates who have to
- 25:27pay power rates right when they're sitting around and they're making those difficult strategic
- 25:31decisions about how Malaysia is going to get his power five years from now where what happens in
- 25:37Australia matters to that at all and that is a fantasy world that is just not the way the real world
- 25:45in the list of criteria that decision makers in developing countries having in front of them when
- 25:51they're making these decisions how virtuous or un virtuous Japan or France is is like a very
- 25:59distance consideration it would make a difference if they were bound to an international agreement
- 26:06that they had signed which was only able to be signed because yeah but they're not going to
- 26:10sign an international agreement that goes against their national interest and that is what John
- 26:16Kerry found out after 10 years of trying to negotiate with with the Chinese is that you can be
- 26:23as virtuous as you want the Chinese have a clear understanding of what their national interest is
- 26:27that national interest does not go through abating carbon power generation anytime in the next 15
- 26:34years and they're just going to send you to suck on the pickle because nothing you can say at an
- 26:38international conference will change the calculus that the Chinese Communist Party has about what
- 26:43it will take to make China prosperous and stable over the next 20 years so I just think we're
- 26:48working on the basis of a very very wrong mental model of how these kinds of decisions are made
- 26:54and who makes these kinds of decisions and it's locking us into a conversation that is honestly kind
- 26:59of hopeless right and that is why there is this much hopelessness in the air is because we we have
- 27:05this idea that we can Hector and morally shame developing countries into putting their all national
- 27:12interests in second place to to our concerns and that's that's just never going well I'm not sure
- 27:19I'm not sure that that's the point of view though I think that the objective is to create a
- 27:24framework of carrots and sticks in which they see their long-term interest as being consistent with
- 27:29a certain amount of short-term pain yes I think that yeah you could you can try to do that but
- 27:36the point is that you've been trying to do that for 30 years and this has been failing for 30 years
- 27:41so at one point do you say okay this thing that we have been trying for 30 years we need to stop
- 27:46doing because it's clearly not working right haven't tried very hard no one's ever been
- 27:50pulled to pulling on the same page at the same time and we've never had a US administration
- 27:54and the European administration and you know all coming together saying that's what the
- 28:01Paris agreement was and and and as hard as you can pull the reality is that in the absence of
- 28:07a world government which would be great if that but we don't decisions at the UN have to be made
- 28:12by consensus which means that Kuwait and Saudi Arabia and Venezuela have to sign on the dotted
- 28:18line right and so this is the wrong conversation this is this is deepening our our commitment to
- 28:26a conversation that will not lead us to where we want to go that's a planet okay what is yeah
- 28:33finished it's also put it it's also putting the interest of that kid in India whose parents
- 28:40farm two acres of land and break their backs and cannot get enough food because now it's too hot
- 28:47now we're saying to that to that kid who's going to go hungry at night to the actual like victims
- 28:52of climate change now that it is more important for us that our feelings of what is morally correct
- 28:59that does take precedence over your actual climate outcomes and their climate outcomes are not
- 29:04decided by how successful the UNF triple C is their climate outcomes are will be decided in
- 29:11large world by the actual concentrations of greenhouse gases in the atmosphere and we can
- 29:17lower those without going through this entire process so this fail for yet right yet I mean that
- 29:25this process will have to be gone through at some point do you agree no no and it is it's also a
- 29:31question of time scales it is happening in the world in the rich countries this is happening is
- 29:36happening slowly but if you if you follow the curve of where the developed countries are by the year
- 29:4521 20 or so in 100 years or now we would get to to net zero right the developed countries are behind
- 29:51that curve they're still developing countries are still raising emissions year on year they
- 29:56will eventually reach a level of development where it becomes feasible for them to then to start
- 30:01lowering their their climate to footprint but that is going to take 150 years and we don't have
- 30:07150 years so we need a solution now that that gets us that that lines up the time scale at which
- 30:16decarbonization can actually happen in the real world in which those equilibrium outcomes of all
- 30:21those decisions about energy point us toward net zero with with the need to have a basically
- 30:28stable atmosphere in the meantime Kiko you have some experience as a reporter of actually
- 30:34sort of living with and reporting on people who live on the front line of the climate crisis can
- 30:40you give us your estimation of where the climate the current trajectory of the climate is taking us
- 30:49this is our hardest question because there are huge uncertainties people don't realize we don't
- 30:58actually understand how particles in the atmosphere interact with clouds and how clouds form and how
- 31:04much clouds in what circumstances shield the earth from solar radiation so there are these like very
- 31:10wide error bars around the international panel on climate changes estimates of where we could be
- 31:17heading so we could be heading anywhere sort of between 2.5 to maybe 3.5 maybe four degrees of
- 31:24warming by the year 2100 so we don't know where we're going to land there is most people think
- 31:29around three but then there's also a lot of uncertainty about what that will actually mean in
- 31:34terms of the climate the people face day-to-day in different places and if three sorry if three is
- 31:41the estimate then where are we now what if we what are we already what we're already at 1.5 we're
- 31:47at 1.5 so we've sort of blown past the Paris Agreement target already although nobody wants to admit
- 31:55that people are you know the proverbial coyote who ran off the cliff and hasn't realized this so
- 32:01hasn't quite started falling it but the reality is that we're at around 1.5 now so we don't really
- 32:08know how livable a three degree warmer world is it's it's sort of simple to create climate models
- 32:17that that show three of three degree warmer world is hardly livable especially in in the tropical
- 32:24band in in the developing world but you can also find there's also a possibility that it's actually
- 32:29not that bad because there are there are all these uncertainties about what exactly means for
- 32:35the inter-tropical convergence something you know it gets quite technical very soon but the
- 32:39reality is that we really don't know what the way to think about this is in terms of aggregate risk
- 32:45there is some sense of like the overall climate risks that we're taking and we know that that
- 32:50the higher the temperature goes the more that kind of a nebulous concept of overall risk the worse
- 32:57that gets but part of it so this is where we're getting at this idea of deep uncertainty we don't
- 33:04really know exactly what that will mean where you live or for your family or for like the family of
- 33:10farmers and this and this into we just know it's risky right I mean this is used by some people who
- 33:16don't want to take action on climate change as a way of saying look we have so much uncertainty
- 33:22about this people get these things wrong all the time so in fact the precautionary principle is
- 33:28just to keep on doing what we're doing basically you know for the best that's the counter I agree
- 33:32to that is is the one I first heard articulated by Arnold Schwarzenegger of all people I think when
- 33:37he was governor of California saying you know if I go to a doctor and they say that there's a 10
- 33:41percent chance that I'm going to die from you know eating skittles or something then I'm going to
- 33:46make sure that I don't eat like I'm going to do everything even if it's very costly even if it's
- 33:51my favorite thing I'm still going to make sure that I don't do it because I don't want that to be
- 33:55to be on the on the cards so I'm just interested in hearing from you what's the bad
- 34:00scenario because you've and where have you where have you been that you see it
- 34:06played out playing I did well I've done some some work on agricultural development in Uganda
- 34:13and South Sudan which are some of the most climate vulnerable places in the world and there is
- 34:18very serious in South Sudan who is one of the very poorest countries in the world it's always
- 34:25when hot like 42 43 degrees Celsius in the in the summer is normal but now they're hitting like 45
- 34:30and 46 and they're hitting thresholds beyond which the survival crops that people rely on to
- 34:37feed their families in these like subsistence farming economies they won't grow like millet will
- 34:44not grow after 45 degrees sorghum like even the hardiest varieties of sorghum just whether and
- 34:50die when you get to to these areas so we're talking around the places where the poorest people in the
- 34:56world live the Sahel Central Africa also parts of the India subcontinent and bits of Latin America
- 35:03this is where it's just becomes genuinely unlivable and so you're either going to
- 35:08see mass migration somewhere or just populations dwindling or who knows what we've never
- 35:14faced anything like that but that's just part of it because there is also this question about
- 35:19the the aim of the Atlantic meridian overturning circulation the ocean current that keeps Europe
- 35:24livable you could have a situation where the Sahel is unlivable because it's too hot but London has
- 35:30the the weather of Newfoundland as well so if you if you break down the ocean currents and that
- 35:36is happening right now if the ocean currents that bring warm waters to Europe stop within some
- 35:42period of time you will have a Europe that is possibly 10 12 degrees colder on average in the winter
- 35:51so the problem with the uncertainty about the possible impacts is that it runs both ways it could
- 35:58be less areas than we think but it also be much more serious than we think and so when you're
- 36:03dealing with risks on the scale and risks that are difficult to measure yeah really think you
- 36:09need to be very careful to be very pragmatic about lessening that changing the atmospheric
- 36:16chemistry in a way that will come as this yeah that North Atlantic current is a real doozy isn't it
- 36:22I mean when you look at a map and you realize that New York is at the same latitude as the south
- 36:27of Spain you realize what legwork the Atlantic is doing in keeping Europe warm with the with the warm
- 36:34water that comes up and some people are sort of quite cavalier about it and they think technology
- 36:39will get us out of this well if London had the same climate as Toronto well Toronto survives yeah
- 36:45but how much how much work and money do you have to put into London into those old streets to re
- 36:51furb London to cope with I mean there aren't even de-icing machines at Heathrow like you know
- 36:57well it's not like yeah and what about all the crops that people have been farming for centuries
- 37:03how do you suddenly where are you suddenly getting your food from on your German farms if they're
- 37:08in permafrost yeah it's but there's so much uncertainty about that because the other part of the
- 37:15AMOX that the God we used to call it the Gulf Stream when I was just called the other part of that
- 37:20question they said we really don't know how long it will take for AMOX to stop once uh
- 37:26once it goes into terminal decline and according to some climate models it's 25 years which is a
- 37:32major crisis but according to others it's 300 years and we just don't know so uh again it's just
- 37:39like deep uncertainty all the way down and when you start to take on the the reality that there
- 37:45are some very bad bad worst case scenarios and we can't really quantify their likelihood is when
- 37:50you start to think okay we need to do something kind of drastic to to to change atmosphere it's
- 37:56chemistry now to prevent this possibility one last uh worry that I've heard articulated
- 38:02Kiko has to do with the monsoons on the subcontinent and the possibility that if the monsoon
- 38:09stops behaving the way that it has for centuries in India and Pakistan and Bangladesh then the refugee
- 38:15crises that we've seen in the past will look like a cakewalk because you'll suddenly have hundreds
- 38:20and millions of people flooding across borders what does that do to Australian democracy and
- 38:26liberalism if you have thousands of boats of you know approaching uh so there are all these knock
- 38:32on effects I mean what happens to Malaysia and Singapore and um what's the probability do we
- 38:38currently know if how should I think about the possibility of disruptions to entire weather systems
- 38:44on which billions of people rely I mean you're talking about the Indian monsoon which is obviously
- 38:51a major problem but the the African Africa has a monsoon too which was already badly affected by
- 38:58by human activity in the 70s and 80s and there we're just talking about normal old air pollution
- 39:03from Europe deeply disrupted this a house monsoon in the 70s 80s into the 90s and you know many
- 39:10political scientists will tell you that the recent country like Burkina Faso and Mali and Niger
- 39:16keep having coups and and there's some of the most unstable and poorest interest in the world
- 39:21is that we've read their ecology by changing their climate already in the 70s 80s 90s through
- 39:27air pollution uh interestingly because of air pollution regulations in Europe making the the
- 39:32air cleaner in Europe that process has actually gone into reverse and now this the hell is is
- 39:38greening again you can actually measure this there's really interesting research on this but the
- 39:42mind is that once you've already displaced the generation of farmers out of their farms and sent
- 39:47them to live in these big sprawling unmanageable cities in the Sahel then all necessarily go back
- 39:53that the farming skills are forgotten those who grandparents used to farm there so people
- 39:58don't necessarily go back after you you repair the damage which we have done so we've already seen
- 40:05this it's not just that the Indian monsoon which is obviously very worrying there are weather patterns
- 40:10around the world there's a possibility that the the rains that sustain the Amazon will just stop
- 40:15right and there are models that show that also happening could end up the Sahara used to be a
- 40:20rainforest a few tens of thousands or hundreds and thousands of years ago so you could end up with a
- 40:26discerning result um if you ask me to put a probability to these how it comes I can't I just know
- 40:34that it's risky and it's risky and getting risky we're doing things that disrupting things and where
- 40:40to we don't have the capacity to understand in what way is exactly so if the conversation if the
- 40:46existing conversation around uh either unilaterally or multilaterally electrifying everything and
- 40:52going renewable is the wrong conversation to have in this state of emergency what is the right
- 40:59conversation to have um look I for me I've looked at this very carefully think we need to um capture
- 41:08carbon dioxide from the atmosphere at gigaton scale you know gigat you say gigatons a billion tons
- 41:14you say it really quick but it's a mind blowing amount of material right now humanity is adding about
- 41:2140 gigatons of carbon dioxide to the atmosphere each year about 10 of those gigatons are absorbed by
- 41:28land carbon things on land and especially in the ocean um if we could expand the ability of
- 41:36land and especially the the oceans to to absorb carbon dioxide we could reach net zero much more
- 41:43quickly um people have some familiarity with this idea because everybody now said if you plant
- 41:48the trees trees absorb carbon dioxide so you get these forestation projects around the world that
- 41:54they help a little bit but as you research this more and more you realize that there's just not enough
- 41:59land like if you do the math uh in order to absorb all the extra carbon dioxide that we are um
- 42:06emitting in on land you would have to uh turn something around the size of all of Canada into
- 42:14tropical forest and there's just not enough land for that you would displays a huge amount of
- 42:19of agriculture people would go hungry you would displays um it's it's it's simply not practical so
- 42:26it doesn't really work so then the question is if you can't do it on land well where can you do it
- 42:30where where this uh photosynthesis work at scale it's in the oceans right so um i work at the
- 42:38Anthropocene Institute right now we deal with a lot of these projects the the center of our
- 42:44concern right now is looking at photosynthesis in the ocean as a potential way of absorbing this
- 42:51extra carbon dioxide how would that work well um there are several different approaches the one
- 43:00that we're more at most interested in is uh inspired by this research project that came out of
- 43:07a French research team in the South Pacific it's published in science in 2023 they found these
- 43:13undersea vents like hydrothermal vents um you look like the level canals under the ocean
- 43:19that are shallow so they're adding chemicals to surface waters and what is it mostly
- 43:25it's phosphate and iron stuff that's in the earth's man uh it turns out that these uh sub yeah
- 43:32these sub sea vents uh fertilize very large like blooms of uh phytoplankton phytoplankton
- 43:39are just tiny marine plants right they're microscopic you can't see them without a microscope
- 43:44but they absorb carbon dioxide they're the base of the food chain in the ocean and
- 43:50there are very large numbers of them around the around the world um except in the center of
- 43:58of the earth's oceans if you're very far from land it turns out that you don't get enough dust
- 44:02deposition from from the continents to fertilize uh these phytoplankton blooms so the center of
- 44:09of the earth's um oceans tend to be very low in phytoplankton and it'll absorb nearly as much
- 44:15carbon dioxide as it could this undersea vent in Tonga fertilizes a phytoplankton patch the
- 44:22size of German okay it's 360,000 square kilometers and it's absorbing 15 million tons of carbon
- 44:29dioxide per year as millions we need to get to billions we need to get to gigatonscale but it
- 44:35it's like we see it as a kind of natural pilot project a natural experiment where nature is showing
- 44:43us what how we could move towards a solution that doesn't require 192 countries to agree and sign
- 44:50under dotted line where some countries in the South Pacific which are among the most exposed to
- 44:56to climate change in the world could take a lead in saying well we can develop our natural carbon
- 45:02sinks and then imitate what nature does and it uses it's a nature-based solution it's using
- 45:08phytoplankton which is the kind of being that initially put oxygen into the atmosphere in the
- 45:13first place there's a reason we have oxygen to begin so it's there uh where we want to study
- 45:18and do you need to seed phytoplankton or are you merely fertilizing existing tracks of the ocean
- 45:25for the existing phytoplankton to flourish yeah no you don't need to see it anything phytoplankton
- 45:31is there it's just not there in concentrations high enough to absorb enough carbon dioxide right so
- 45:38what's interesting about this is that this in principle could work in most of the world's oceans
- 45:43they could work in the north Atlantic and the south sorry in the north Pacific and the south
- 45:48Pacific it could work in the Indian Ocean and it could work in the south Atlantic Ocean it could
- 45:53work in the north Atlantic and the reason why it's quite interesting is that the north Atlantic is
- 45:58already naturally fertilized by dust from the Sahara so there's this simple the Sahara
- 46:04near layer which is a layer of dust-faring bearing um air from picked up from the Sahara that
- 46:11actually covers most of the north Atlantic and there's a reason the north Atlantic on that per unit
- 46:16basis captures about twice as much carbon dioxide as the other as there are other oceans um there's
- 46:24just more life in the north Atlantic there's there's always winter rich fisheries in the in the
- 46:29north Atlantic for for this reason so really the the proposal that that we're thinking if we think
- 46:36five ten years south is well what if we could bring the uh the world's other oceans to the level
- 46:42of phytoplankton productivity that the north Atlantic already has let's take it we're not talking
- 46:47about something that would necessarily be a visible change like to the naked eye who just look the same
- 46:53you would just have livelier um ocean ecosystems in these other in these four other oceans you
- 47:00probably is it's hard to say for sure but common sense indicates that if you have more phytoplankton
- 47:07you would also have more of all kinds of marine life soil plankton krills whales fish marine birds
- 47:16so one thing that we do know from looking at the the natural site in Tonga is that the natural
- 47:22site in Tonga does not seem to have a normal ecology in any way in fact is um when when nature does
- 47:28this naturally through through undersea vents you end up with um eco like biodiversity hotspots
- 47:37right and and very good fishing grounds so it does look like it could be ecologically
- 47:42quite benign it's not expensive because we're talking about very simple minerals in very low
- 47:48concentrations they're not really talking about a lot of iron we're talking about
- 47:53um the math we've done shows that the weight of a human eyelash per ton of seawater would be enough
- 48:00to raise the productivity of their self-specific to something close to what the north of the
- 48:06Atlantic has so honestly this to me it seems like a much better conversation to be having about
- 48:14a actually realistic way to to get to to net zero within a relatively short period of time
- 48:20short enough to give the world the time to decarbonize that that it would need which is
- 48:26on the different times and phytoplankton is not algae it's micro algae it's micro algae micro
- 48:33algae okay got it and then so just to clarify to paint a picture in people's minds are we talking
- 48:38about ships or aeroplanes spraying fertilizer into the south Pacific but that's all to be worked
- 48:47out there are lots of technical questions i'm sorry to answer but seeing we're backing a project
- 48:53called growing oceans i can go to growing oceans dot org and see all the the technical detail
- 48:59all of that is still to be worked out for example how exactly how much iron and how much phosphate
- 49:05delivered how what we need is like a three to three year research program to go to the self-specific
- 49:13to understand the ecology of phytoplankton and so plankton in the region in much more detail and to
- 49:19begin maybe then if it turns out to be ecologically safe and if the local people wanted because we're
- 49:26working in people's territorial waters right to then begin to experiment with with what nutrient
- 49:34additions would do so we don't know all the details a lot of the science remains to be worked out
- 49:39we just have this initial indication from nature that this could be done and this could be done
- 49:46so part of people's reticence i assume when you raise this is the past examples of humans trying
- 49:52to introduce something into an ecosystem uh you know Australia has a problem with a uh
- 49:58a floral pest called the prickly pear so the hawaians have a great idea of giving us a cane
- 50:05toad to eat the the insect that is going to get the prickly pear and it's just this cascade of
- 50:11of i'm maybe misremembering that or butchering it but you know now we have an intractable pest
- 50:16problem where the cane toad has no natural predators uh ecosystems function in complicated ways
- 50:23you know you have more phytoplankton what does that do to the coral reefs how does coral
- 50:28respond to the phytoplankton does the phytoplankton create more shade in the water so that there's
- 50:32less solar radiation for the fish at the bottom to get like all of these knock on uh effects
- 50:38what what do you say to people who say like this is not the right way we just need to
- 50:43what did you reduce the color there's a there's a couple of things about this first wouldn't be
- 50:49the idea is not to introduce any organism that it's not naturally in the water already it's just
- 50:56feed organisms that are in the water and in fact what we would be doing in many ways is just
- 51:01restoring the situation that we had 150 years ago so until 150 years ago we have good evidence
- 51:08that the center of ocean gires used to be more productive than it is now and the reason
- 51:14that was more productive is that we had lots of whales whales eat at depth where there's lots of
- 51:20nutrients in the water and then they come up for air and then when they come up for air they tend to
- 51:25do a number two and actually whale feces turns out to be an excellent fertilizer for phytoplankton
- 51:33and there's quite a bit of research. I appreciate your politeness in calling it a number two you
- 51:36can just call it a giant whale shade on this show that's so well that's exactly what they do
- 51:43when when they when you actually you could actually look this up it's called a biological pump or
- 51:48the whale pump and there's very good evidence that because of the legacy of industrial
- 51:54whaling we've lost the ability oceans have lost the ability to cycle nutrients from depth
- 52:00to the surface where phytoplankton can grow and that's one important reason why there's now
- 52:05less phytoplankton that there used to be so this we're really talking about recreating a situation
- 52:11that we used to have where oceans were a more higher performing carbon sink than than they are
- 52:18now that's one thing but the other thing to say about this is that of course you're right oceans
- 52:23and ecosystems are big difficult to model unpredictable things which is why the project that
- 52:29where they were packing growing oceans is being very careful to do this in a stage gated way so
- 52:36the model we have in mind is very it's patterned on the way that drug development happens so when
- 52:44you go to develop a new drug you start with laboratory experiments and you assess for safety and
- 52:50efficacy if it's safe and if it works then you go to a small trial and then you're going to assess
- 52:56and if it's safe and it works you go to a slightly larger trial and you keep doing that by each
- 53:00point you have a moment when you actually stop and you look at the data and you need permission
- 53:07from a regulator to go forward so you know we are not crazy people we are working with university
- 53:15based colleges who understand the issues at play and you know we don't know if it's going to work
- 53:23this is an idea at this point what we do know is that we should definitely be exploring whether
- 53:28this is a possibility because this could this kind of approach has a potential to get us to gigatons
- 53:36scale carbon removal that the UN process has already shown that it does have right when you say
- 53:43gigatons scale carbon removal you mentioned earlier that the natural Tongan hydro thermal jets that
- 53:50are doing this have covered an area of the South Pacific the size of Germany that absorbs 15
- 53:57million tons is that right but you were talking about needing 30,000 million tons does that mean
- 54:06that the difference in 15 and 30,000 is a lot does that mean we need hundreds of Germany hundreds
- 54:12of areas hundreds of Germany's worth of the South Pacific treated look potentially if we can what
- 54:20part of this is that we need to bring South Pacific nations along for for the right this needs to
- 54:25be something that is in their interests and that works for their coastal communities and for
- 54:29their people right so this cannot be us telling people in Tonga or in Vanuatu or anywhere else in
- 54:36the region okay like we are here the foreign deal the white willing list we're going to tell you
- 54:40what to do that that that's just not going to work however if we can demonstrate that that
- 54:47this technique is ecologically benign that is good for fisheries maybe that's something that we're
- 54:52actively going to be monitoring it takes several years to see an effect on fisheries but in principle
- 54:57there should be what and if we can demonstrate that this is safe then what we hope to be able to
- 55:02say to our partners in the South Pacific is your islands are definitely threatened by climate change
- 55:09here's a way that your ecology and your coastal communities can benefit maybe if we manage to
- 55:15sell some of these tons of sequestration to on international markets or to other people maybe you can
- 55:23have a direct economic benefit as well the idea is that if we manage to do that then we will get
- 55:30an imitation dynamic around the South Pacific where Tonga might be first but then somehow I might say
- 55:35okay well we want in on this too and eventually you you grow and you grow until you cover
- 55:41enough of the South Pacific that you are beginning to get to optimize first of all the carbon
- 55:47sequestration because the volcano is not optimized as hydropower vent is just dealing now we think
- 55:53it might be possible to do better than than the hydropower vent is doing and where you can grow
- 55:59across the South Pacific and then eventually you can start to talk to partners in the South Atlantic
- 56:04Indian Ocean and in the North Pacific and within 10 or 15 years you could be looking at possibly
- 56:13tens of gigatons so tens of billions of tons of carbon dioxide if it if it all goes well can't
- 56:21promise that of course yet because I mean there wasn't a system yet but that's what we're doing
- 56:26one of the one of the risks keep going for the marine environment from climate change is not just
- 56:32the warming temperatures but also acidification of the oceans which many Australians are deeply
- 56:38concerned about since we have the world's largest coral reef obviously and it's already showing
- 56:42the effects of ocean acidification in terms of bleaching coral you know we also function I
- 56:49suppose geopolitically as something of a of a deputy sheriff to the South Pacific and they're
- 56:54the go to you know the go to rich democracy in their eyes big rich democracy that countries
- 57:01like that treat as an sort of an interlocutor to the rest of the world so the the queue the queue
- 57:09is running on that action too but yeah we're working on yes the queue is absolutely yeah yeah
- 57:15yeah well they do but they're they're a lot smaller so they it's harder for the New Zealand
- 57:21Prime Minister to get the president of the United States on the phone than it is for the Australian
- 57:25Prime Minister um so the question is what do we know what impact this might have on acid on acid in
- 57:31the oceans again because this has not been actually done this is just a project we cannot
- 57:39say for sure but as a matter of theory the thing that if acidifies the ocean is inorganic carbon
- 57:47so it's carbon dioxide that's just diluted in the water when you stimulate phytoplankton
- 57:52phytoplankton absorbs an inorganic carbon and builds it into organic particles organic particles
- 57:58do not cost ocean acidification so on a large scale this should combat directly combat ocean acidification
- 58:05we have to measure it but that's a theoretical question this is actually my institution
- 58:11answer to seeing is also an ocean conservation institution when we do protection for marine
- 58:17protected areas and we fight illegal fishing and krill fishing around the world and for us ocean
- 58:23acidification is the major one of the major reasons we're interested in this phase and we're
- 58:28interested in this solution this is directly what address ocean acidification as well as global
- 58:36right so it seems to me that something like this stands its best chance of success if it was paired
- 58:42with a strategy that also as you mentioned maybe enabled people to sell the carbon credits
- 58:49into jurisdictions that have carbon a price on carbon carbon trading schemes and so on it strikes
- 58:56me also that many of these governments might initially have a response of saying well this seems
- 59:02like a quick fix so that you don't have to do the hard work of getting carbon emissions down so
- 59:06let's see this when it comes paired with some sort of a global strategy to do both and we can trust
- 59:12that this is not just a way for you to buy yourself more time to keep emitting as much as you want to
- 59:18would bring me back to my original concern which is if we lack the ability to solve the coordination
- 59:24problem of doing something about getting emissions down how do we pair this with a context where people
- 59:31will perceive it as anything other than a stopgap that prevents us from having to face the actual
- 59:37problem I mean this has stopped that stopgap it's what we need to do it in the meantime while
- 59:44well we have time to to decarbon this but I guess my answer to that is that we have that framework
- 59:48that framework is called the Paris climate agreement I mean it's in Paris just a bunch of countries
- 59:53saying oh yeah you know we hope that we I mean making pledges with no mechanism no specificity
- 1:00:00no guarantees no penalties no anything it's just a bunch of countries saying yeah we can write
- 1:00:06down on a piece of paper that we're going to get to net zero by xdate but there's no there's no
- 1:00:11actual framework in which people are held accountable to doing particular things
- 1:00:17isn't yes and no yes and no there's not an international framework but many jurisdictions
- 1:00:23have created a legal obligation to meet the nationally developed determined contribution
- 1:00:29under Paris so under the European Union polluters are legally obliged to to meet to to lower
- 1:00:36emissions to meet the NDC under the Japanese green transformation system there is a legal
- 1:00:44obligation to cut carbon to breach that the naturally determined contribution so the you know
- 1:00:51my particular take on how this can these two things can be made to go together so the Paris
- 1:00:58agreement also includes article 6.2 this gets a little bit technical but article 6.2 is part
- 1:01:04of the agreement that allows countries to trade their mitigation outcomes so that if your
- 1:01:09country is mitigating more than their nationally determined contribution they can sell
- 1:01:14that extra mitigation to a country that is finding it hard to do that right so you can imagine
- 1:01:19the situation where countries in the South Pacific are drawing a lot of carbon down from the atmosphere
- 1:01:26and countries, Japan, Singapore, Switzerland, European Union, Canada, Australia,
- 1:01:31not the US for now but eventually the American still can can can go and and actually pay
- 1:01:40money to book those emissions reductions in their own books. Right now I'm no expert on the lore
- 1:01:48of the sea and who controls what and where international waters begin and end but why do you need
- 1:01:53the buy-in of small countries when the North Pacific and the equatorial Pacific is so vast why can't
- 1:02:01you just why can't one country just unilaterally go out into the middle of the Pacific a thousand
- 1:02:06miles from any country and just start doing this. There are a lot of there are a lot of reasons.
- 1:02:14I mean our reason for starting in the South Pacific is precisely that we do think it's important
- 1:02:20for integrity that there be a regulator right like we you know I wouldn't trust any group to just
- 1:02:27start doing this on their own. They are international conventions like the London Protocol and
- 1:02:33and other international legal instruments that mean that you do need to meet certain requirements
- 1:02:39so for example this has to be done afford a legitimate scientific basis and a non-commercial
- 1:02:46basis so that the approach that we favor is absolutely non-profit this cannot be a cash group.
- 1:02:51To the extent that there is money flowing it should be flowing to the countries that
- 1:02:56that actually have the water surrounding that that can make this work. It calls them small countries
- 1:03:01I actually reject that now these say as we don't call them small small island states we call them
- 1:03:07big oceanic states right they're the boss right they it's it's their territorial waters
- 1:03:12and this and the but also because the biogeochemistry of the South Pacific is particularly
- 1:03:18favorable to the approach that we are pursuing there's more phosphate in the water to begin with
- 1:03:22some phosphate it's less likely to become a limiting factor and because look when you try to do
- 1:03:29this very very far from land your cost rise very quickly because the logistics of getting that far
- 1:03:37into the ocean become very complicated when when you're in the South Pacific the island is
- 1:03:43the vessel you can use it the the string of islands as as a forward operating base
- 1:03:48it just becomes logistically much simpler so there are a lot of reasons to start in the South
- 1:03:53Pacific eventually you know you can imagine fleets of sort of sealed rounds doing something
- 1:03:59like this in more remote areas like they they aren't really a lot of islands in the South Indian
- 1:04:04oceans for instance so if 10 15 years from now we're at a place where we feel like that needs to
- 1:04:09have a in the South Indian Ocean too we'll be having a different conversation but this is all
- 1:04:14getting far ahead of ourselves I'll talk to the West Australian Premier and see if he can do
- 1:04:18something because probably this probably Perth is probably the best located city from which to
- 1:04:23a lot of things into the South Indian Ocean Coco silent would be perfect yes actually great
- 1:04:28it would be a great place to do it from so but that's a conversation for 10 15 years from now
- 1:04:32what we need to do now is establish the science establish the safety and establish the efficacy
- 1:04:38of the technique if five years from now we can have another conversation Josh and they can
- 1:04:43say look we know this is safe we know this works we know the cost is really really low
- 1:04:49then I think we would be having a very very different and much more hopeful climate debate
- 1:04:54climate debate that's not such a bummer where it's all about how we're all going to die and how
- 1:04:59kids in Africa aren't going to have enough to feed themselves I just think we need we need to change
- 1:05:06this conversation and the way to do that is to develop the techniques that will make this work
- 1:05:10because we've been talking about fight of plankton about microalgae there are other groups out there
- 1:05:16experimenting with doing things like this with seaweed with with big seaweed with you know our
- 1:05:21take at acid percentage that's less likely to work because it's just that the economics of it
- 1:05:26are trickier but we could be wrong it could be that it's big seaweed that that does it there are
- 1:05:31lots there are lots of different people experimenting with things like this but now our hunch
- 1:05:37which were wait I mean I'm personally completely convinced is that the solution is
- 1:05:44photosynthesis in the water and just to clarify when you when you think about photosynthesis on land
- 1:05:50and planting trees yes those work to suck up carbon dioxide but only for the life of the tree
- 1:05:57and then you have to make sure that the tree grows into another tree and once the tree dies the
- 1:06:02carbon gets released unless it grows into another tree what happens what is the life cycle of these
- 1:06:07photo plankton and how do you when they die don't they just float to the bottom of the ocean and
- 1:06:11release the carbon again unless you keep fertilizing the ocean like is there any end to this um so
- 1:06:18that is one of the that's a very good question that is one of the key scientific questions that we
- 1:06:23need to answer our understanding and and what we hope to prove with growing oceans hopes to prove
- 1:06:31is that the mean length of sequestration for the the technique that we're proposing is around 3000
- 1:06:37years when phytoplankton falls to the bottom of the ocean it keeps it keeps the carbon dioxide
- 1:06:44with it at the bottom of the ocean that's what that that is the ultimate storage place is is
- 1:06:48the ocean depth or the bottom of the ocean in a way all we're doing is closing the carbon loop
- 1:06:54we have all this extra carbon dioxide in the air because we've been burning oil but what is oil
- 1:07:01oil is just concentrated ancient phytoplankton 99% of the oil that we have is actually used to be
- 1:07:10phytoplank so that's how the carbon got there in the first place just talking about closing the loop
- 1:07:15so just the phytoplankton sorry not decompose in the ocean and release the oxygen it floats
- 1:07:20that's another another question so this this is something that we are absolutely need more science
- 1:07:27on the hypothesis we're working on is that most of the phytoplankton when once it's fertilized will
- 1:07:34be eaten by usually zooplankton which are little microscopic animals when zooplankton eats them
- 1:07:42because well this this necessarily gets a little bit technical that's okay the technique that
- 1:07:48we're proposing fertile doesn't fertilize phytoplankton directly what it does is it fertilizes
- 1:07:53organisms in the ocean that capture atmospheric nitrogen okay what's really limiting the growth
- 1:07:59of phytoplankton in the center of of subtropical oceans is actually that there's not enough fixed
- 1:08:04nitrogen but there are organisms in the ocean that can capture nitrogen from the air and fix it
- 1:08:10into ammonia and fertilizer basically our approach is sent and what this French team that worked on
- 1:08:18the subsea vents in Tonga found is that what those fans do is stimulate nitrogen fixation okay so
- 1:08:25now you have you're adding nitrate fertilizer to the ocean except you're you're letting
- 1:08:31microorganisms already in the ocean through this nitrogenase process do that so yes you're right
- 1:08:38that the phytoplankton will be eaten by zooplankton and the zooplankton through cellular
- 1:08:43respiration will then release the carbon dioxide but they'll also release the added nitrate that
- 1:08:49those nitrogen fixers fix and so now you have both of the things that you need for a new cycle of
- 1:08:55sequestration right so now because there's nitrate and carbon dioxide in the ocean you'll have a
- 1:09:01new phytoplankton do that and that can continue happening it's like each time you do that it's like
- 1:09:06the the little phytoplankton is buying a lottery ticket and on one of those cycles it's just going to
- 1:09:12sink okay so how long will that cycling continue to happen what our team is trying to prove is that
- 1:09:19that will continue to happen until the nitrate fertilizer is pulled apart but what we
- 1:09:27understand that happens in very limited parts of the ocean mostly off the coast of South America
- 1:09:31and the mean time it takes for nitrate to get from the center of the Pacific to the west coast
- 1:09:37of South America it's about 3,000 years so right so we believe that the mean length of sequestration we
- 1:09:43can prove will be 3,000 3,000 years right so the idea just just to clarify the idea is that the
- 1:09:50carbon that is being consumed by the phytoplankton either remains in the life cycle of the ecosystem
- 1:10:02because the phytoplankton gets eaten by a zooa plankton a little tiny little animal and then when
- 1:10:07it dies its constituent parts then get repurposed into new phytoplankton or little bits of it
- 1:10:15will sink and then turn into a future oil that's exactly right is that right amazing um
- 1:10:24we have proof all this this is a few you gotta prove it all we gotta prove it but we're working
- 1:10:29on proving we have a really cool team we have scientists from the University of Southern California
- 1:10:33leaving this or University of Hawaii from the University of Alaska we have people from the
- 1:10:38University of the South Pacific this science led team working on this could be wrong we tend to
- 1:10:46and every meeting saying but it might not work yeah right right like what about this sounds
- 1:10:54moderately complicated in terms of the involvement of the ecosystem the marine ecosystem in
- 1:10:59absorbing carbon there have been other plans to mitigate the effects of climate chaos that don't
- 1:11:06address carbon directly but reflect sunlight for example back into the atmosphere people have
- 1:11:13talked about putting satellites up with mirrors on them that reflect some sunlight will many people
- 1:11:18have heard of the ideas of spraying self a dioxide or something white colored into the atmosphere
- 1:11:24or seeding clouds by just having ships go through the ocean and spray water moisture up to reflect more
- 1:11:31you know what do you make of those more ad hoc plans to not address the actual content of carbon
- 1:11:38in the atmosphere but to to slow down the warming of the planet yeah it's tricky I mean it seems
- 1:11:47like that's a question of science like a woodwork and and the scientists I've talked to think it
- 1:11:52would be possible to manage the the secondary impacts on things like rain cycles and the
- 1:11:59monsoon that we talked about like it seems like it would actually work we tend to be very skeptical
- 1:12:07of those for two reasons you talked about acidification this does nothing for acidification
- 1:12:12and in fact by creating an atmosphere where it's comfortable for polluters to keep polluting
- 1:12:18its threads to make ocean acidification much more for problems so that's the thing that
- 1:12:22concerns us a lot the other thing that concerns us is the collective action problems unlike
- 1:12:29these phytoplankton solutions where you just need one country in the South Pacific to to sign up
- 1:12:33and then it's territorial waters you can go really you would need an agreement minimally
- 1:12:40between the US and China more likely between several large countries that don't agree on anything
- 1:12:46and if you join without such an agreement then you you could be creating geopolitical tensions
- 1:12:53that you can imagine like going to a war I just get very but like I am not comfortable
- 1:13:00advocating a solution that could destabilize geopolitics in that way it is a last last last
- 1:13:06or sort me if this phytoplankton thing doesn't work and we start seeing really out of control
- 1:13:12climate impacts in two or three decades I can imagine you might be doing that as a really
- 1:13:19as a as a last resort but what do you do this if you do this it is for sure that the year after you
- 1:13:27you start a stratospheric brightening approach there will be freak weather somewhere right like
- 1:13:36because there's freak weather somewhere every year how are you going to convince those people
- 1:13:40they even do it to them and how are you going to prevent those people from going to war with you
- 1:13:45because now you're messing up their claim okay so now you're going to need some kind of loss and
- 1:13:50damage mechanism I suppose that's a concern Kiko but I can also imagine you know they're being an
- 1:13:56irregular year of fishing in Indonesia or the South China Sea and then blaming it on these
- 1:14:03huge phytoplankton farms off the coast of Vanuatu and and that causing diplomatic problems as well
- 1:14:11I mean I don't see why China putting up a bunch of satellites to reflect more solar radiation
- 1:14:18is necessarily more aggressive geopolitically than coating the South Pacific in phytoplankton
- 1:14:27in order for us a solar radiation management approach to be effective you would have to be doing
- 1:14:34globally really otherwise you would really threaten the in the radiation balance between the
- 1:14:40northern and southern hemispheres you could be making things very much worse I do think
- 1:14:46you need coordination for a stratospheric approach in a way that that is just not the same as you
- 1:14:52would get in with a phytoplankton basic approach but also you fundamentally the stratosphere you
- 1:15:00would not be bringing the atmosphere back to this condition where it was at before you'd be creating a
- 1:15:06new weird atmosphere that is both very high in carbon dioxide but also mess with in that you
- 1:15:13would have more reflected light which would have impacts on agriculture you'd be creating a
- 1:15:19completely new kind of atmosphere and there I do think that you're talking about introducing
- 1:15:24new risks especially geopolitically but also also physically and we don't know how to manage okay
- 1:15:34so I don't want to say that this is a no-go and that this will never work maybe it'll work scientifically
- 1:15:40it seems like it could work it seems like we'll be in exchange to me it is plainly a less desirable
- 1:15:48avenue than to actually address a root cause which is carbon I see so anything that basically turns
- 1:15:55the clock back on the amount of carbon in the atmosphere we should think of as being in one category
- 1:16:01and then another category would be things that don't address reducing carbon and just try to
- 1:16:06mitigate the climate effects alone what about carbon capture and storage that we were all hearing
- 1:16:12so much about 10 years ago and then not artificial ways of sucking carbon out of the atmosphere
- 1:16:20they are they cost between 10 and 100 times more than what we're proposing so they exist
- 1:16:27they're not economically viable and they face fundamental physical barriers to seeing quick
- 1:16:34drops in place because they just require a lot of energy some of them require a lot of material
- 1:16:41there some people who are wanting to increase the alkalinity of the ocean by putting alkaline minerals
- 1:16:47into the water that requires moving shifting huge like billions of tons of material and mining it
- 1:16:54which has its own environmental footprint but more than that it just becomes very very expensive
- 1:17:02the other part that is important about the phytoplankton approach is that it's uniquely low cost
- 1:17:09and it brings a ton of carbon sequestration down to maybe $10 a ton whereas these other
- 1:17:15approaches are between the hundreds and the wealth thousands of dollars per ton okay so then let's
- 1:17:21just end by talking about how we generate energy because as you say this is only a stop gap before
- 1:17:28we have to deal with the carbon emissions themselves a lot of people will receive this kind of a
- 1:17:36proposal as you know what it reminds me of a bit Kiko is often governments and the Australian
- 1:17:43government does this and has just done this again to combat the unaffordability of housing
- 1:17:50will provide a first homeowners housing grant to young people where you know they'll give them
- 1:17:57a certain amount of cash in their pocket to help them buy their first home which is great in the
- 1:18:02short term and in the long term of course increases property prices more because this you know
- 1:18:07it makes the problem worse and so the concern with a solution like this is that all it does is just
- 1:18:13buy us however much more time it buys us that will just get banked in by professional fuel industry
- 1:18:21and governments as a way to continue stalling until the shit hits the fan and all it really does
- 1:18:27we're just gonna we're gonna absorb the benefit keep pissing our future up against the wall
- 1:18:34for as much longer as we can and then we're still gonna have to face the music at some point
- 1:18:40anyway so can you just address that and then talk about the energy electricity generation side
- 1:18:45of things and I mean we absolutely do need to decarbonize as well it's just that from our point of
- 1:18:54view an answer presented we think a lot about this question of the green halo now there are
- 1:19:01certain technologies that have just this aura of saintly that's when I'm thinking about
- 1:19:07solar and when they just they look great on a billboard they make us feel good they have this
- 1:19:12like feel good sense of like wow this is such a low impact thing and because they have this
- 1:19:17green halo is prevented us from being quite critical enough in understanding some of the limitations
- 1:19:24of some of these weather dependent renewables when you actually go and do the mathematical modeling
- 1:19:31you realize that these technologies are affordable as long as they represent a relatively small
- 1:19:38portion of your energy mix when you start to hit 40 50 60 percent now you have a very
- 1:19:45variable source of electricity that is all correlated with each other because if it's sunny
- 1:19:50here it's probably sunny over there and if it's nighttime over there it's probably nighttime all
- 1:19:54around your system so to you end up with a highly variable source of power that can create
- 1:20:02big swings in the price of power for one thing but but also just brings fragility into the system
- 1:20:08as well as requiring quite quite a lot of land so I think we've been less hard headed than we
- 1:20:13should have been about asking hard questions about what it will really take to to get to
- 1:20:20reliable stable predictable firm sources of zero carbon power and from our point of view
- 1:20:28clearly the superior answer to this is nuclear energy nuclear energy is cost competitive with
- 1:20:35other forms of energy now even though the nuclear energy that we have is built is based on
- 1:20:42these reactors so we're designed in the 1950s is boiling water reactors or pressurized water
- 1:20:48reactors that were designed without computers with like people with slide rules and without
- 1:20:53advanced materials so they're shit like these are not good energy technologies but even those are
- 1:21:00cost competitive but the next generation of nuclear reactors of these small modular nuclear reactors
- 1:21:07that are being researched now being developed now all right fundamentally safer some of them are
- 1:21:14incapable as a matter of fundamental physics cannot melt down produce up to 99% less nuclear waste
- 1:21:24and the nuclear waste that they do produce can be reprocessed into new fuel and could if they were
- 1:21:32manufactured at scale if they were manufacturing the factory and cranked out one after the
- 1:21:37other after the other eventually just have a clear cost advantage over both weather dependent renewables
- 1:21:44and fossil fuels we have seen that this sort of nuclear Shangri-La has been promised for a long time
- 1:21:50it hasn't quite come because it's difficult to get enough and it is expensive to develop it's not
- 1:21:55expensive once it's going but it's expensive to develop and it's turned out to be quite difficult
- 1:22:00to get a demonstration plant running and and to get us to the place where you do start cracking
- 1:22:05them out we believe that by 2030 is what's going to happen is that one or two of these advanced
- 1:22:11small modular designs will prove itself to be the superior choice then we're going to start
- 1:22:16building them at scale and then we're going to realize that this is just the obviously better way
- 1:22:20to produce zero carbon then when you say that these newer designs are incapable of melting down
- 1:22:27I think a lot of people either find that fishy or unaware of it do you understand the physics of it
- 1:22:35I remember reading something about how some of them are actually suspended over like a water
- 1:22:41plant or something and like when they melt down they like drop into a basket of you know they're
- 1:22:47a pebble bed reactors I don't understand but can you just give us a sketch of what we're talking about
- 1:22:51or do you do not know I am not a nuclear physicist so I don't understand this in detail at all
- 1:22:58but what I do now is that after the Fukushima accident here in Japan there was a moment where
- 1:23:02that people in the nuclear industry understood that passive nuclear design it passive safety design
- 1:23:09or what is sometimes called walk away safe designs would be necessary in any future nuclear design
- 1:23:15so the design principle became how do you design a reactor such that even if everybody in the plant
- 1:23:23goes crazy and walks away and just like mid centers leaves the thing shuts down of its own and
- 1:23:28it is possible in fact to create designs where if the design is intended and begins to get too hot
- 1:23:35then the the thing changes state and then the the nuclear reaction stops as far as I know
- 1:23:41every single advanced small modular nuclear reactor design that is that is being done right now
- 1:23:48incorporates these aspects of walk away safe design some of them do have mechanisms where
- 1:23:55if it gets too hot then it triggers a mechanism that is fat that nobody has to activate
- 1:24:02just triggers something so that makes the reactor core fall into a into a substrate that will stop
- 1:24:10the reaction there are different ways of doing this that people who are way smarter than we have
- 1:24:14been working on for a decade and a half understandably regulators have been like
- 1:24:21very eager to double triple and quadruple check that these designs are actually going to be a safe
- 1:24:26as they say they are and yeah regulatory concerns have also slowed down the development since these
- 1:24:34designs but because it's taken a long time and it is taking a long time we've ended up in this
- 1:24:40weird situation where people kind of feel like they already know about nuclear like they've seen
- 1:24:44their opening credits in the simpsons and they know what a nuclear power plant where it looks like
- 1:24:49they know that it's dangerous and they they just think it is that one thing and this
- 1:24:54message that there are much better designs that are being worked on that are fundamentally safer
- 1:24:59and fundamentally less polluting or that they produce it much much less nuclear weight
- 1:25:06waste that's a message that hasn't really gone through over the next few years as companies
- 1:25:11like Oakville and Terrestrial Energy and Terrapower and Altua and Bicala and a lot of their around
- 1:25:21the hundred companies now right now developing these small modular reactors many of them will go
- 1:25:27bankrupt and they just won't make it to production stage but some of them will not and the
- 1:25:32state becomes begin to come online and we're going to have a moment of realizing that this is just
- 1:25:37a clearly superior way of getting to to stable reliable zero carbon electricity and so at answer
- 1:25:45we are advocates for nuclear power very angry that this this is not happening more quickly
- 1:25:51so we want to change the conversation so the strategy basically is
- 1:25:59would you say we need to continue attempting to solve the collective action problem of meeting
- 1:26:04and having gapfests and talking about things or do we just go full steam ahead with trying to get
- 1:26:10as many jurisdictions to be as friendly as possible to an energy mix that has a minority of
- 1:26:15base load nuclear a majority of renewables for the rest and an aggressive collaboration on carbon
- 1:26:24absorption technologies like Shadow Plankton as a possibility is that is that the model there
- 1:26:30there is no stopping the UN process the UN process is now has a moment of it of its own it has
- 1:26:36a bureaucracy of its own it they are in every single capital in the world they are
- 1:26:40diplomats who specialize in this that is not going to stop it has the limitations that it has
- 1:26:46but what we think is that we need to refocus from considering this UN process as the center of
- 1:26:51the solution to understanding that the UN process hasn't advanced quickly enough because the
- 1:26:56technologies that would unlock the problem haven't been there so if we were having a conversation
- 1:27:04we're responsible to get base load power from nuclear energy with zero carbon that was affordable
- 1:27:08and reliable and fundamentally safe and it was possible to absorb carbon dioxide add gigatons
- 1:27:14tail into the ocean then you would be putting the video game on the very easy setting for the
- 1:27:20UN climate diplomats won't make their lives easier so that reaching these agreements doesn't become
- 1:27:26we began this discussion by me telling you that you cannot convince a policy maker from Malaysia
- 1:27:34or from South Africa to commit political suicide by agreeing things that will cut their career
- 1:27:41short because the lander people and they'll stop their development prospect if we can create a
- 1:27:45situation where it's easy for them to say yes because they don't have to be a development
- 1:27:50price in order to agree to zero carbon technology then the UN process will be unlocked but the
- 1:27:55problem is technological it's not the problem. Kiko it's fascinating stuff I look forward
- 1:28:01to the day when you and I sit down with the premier of Western Australia and the leader of
- 1:28:06Samoa and and gaze out over vistas of Fato Plankton in the South Pacific. I cannot wait. Thanks for your time.
