  Casey: Hey there, glad you're here. Today we've got thirteen Chilcotin pile burns stretching into January, a Cambridge study that says comets probably didn't seed early Earth with the chemistry for life, and a Mali meteorite that may be older than any Martian rock we've found. Then the deep dive asks whether twenty years of watching a place earns you a say in what happens to it. Let's get into it.

  Casey: Welcome to Cariboo Signals, an AI-generated review of the latest tech news and ideas that impact our rural communities. I'm Casey. It's Sunday, November 1st, 2026. Today's theme is Science, Wonder & the Natural World. Here in the Cariboo, on the traditional and unceded territories of the Secwépemc, Tŝilhqot'in, and Dakelh nations.
• 0:56
  Riley: And I'm Riley. Ice cores, comets, a dinosaur from a quarry, and a few stories from right here. Out at Horsefly Lake this morning it's foggy and around minus 2, with a high of 6 today and no precipitation expected. Across the Cariboo, 100 Mile House is around minus 4 and clear, Williams Lake is around minus 4 with fog, Quesnel is around minus 3 and clear, and Anahim Lake is around minus 6 under overcast. Heads up if you're driving into Williams Lake, where the fog is the thing to watch.
• 1:29
  Casey: A good share of today's news lands in our own backyard, and the rest is a long way from it.
• 1:35
  Casey: We covered the Chilcotin pile burning on Friday, and the new detail is the calendar. The burning runs through January 31st, 2027, as part of about thirteen wildfire rehabilitation projects. It was postponed in November 2025 so the wood could cure, and cured fuel burns cleaner with less smoke.
• 1:53
  Riley: A year's wait for cured fuel is a low-tech way to cut smoke.
• 1:59
  Riley: Downtown Trick r Treat in Williams Lake was set for Saturday, with 22 businesses signed up to hand out treats. Halloween fell on a Saturday, and many businesses, including professional services and government offices, are closed on weekends. At one point fewer than half as many businesses were participating as the year before, and cancelling was on the table. Jazmyn Douillard, who runs the event with her mother Joan, kept it going. The 2 p.m. start was picked for toddlers and kids who get overwhelmed, because the street is quiet then.
• 2:32
  Casey: Ottawa has designated the Roberts Bank Terminal 2 expansion at the Port of Vancouver a project of national interest. It's a $5.9-billion container terminal in Delta, and the federal government expects it to lift the port's container capacity by about 50 per cent. The project received federal environmental approval in 2023 and is still waiting on final permits. Transport Minister Steven MacKinnon says the designation brings certainty on timing, and that commercial operations could start in 2035 instead of 2039. The government estimates about $3 billion a year in GDP during operations.
• 3:09
  Riley: Thirteen years of review, and the minister says it's time to decide. The consultation record is the part I'd read before the permits land.
• 3:18
  Riley: At the Ckultenellcw Cultural Centre, a photo exhibit called Preserving Salmon For Winter Food opened on Thursday, October 29th. Williams Lake First Nation Elder Helen Sandy made the photographs over twenty years, documenting Indigenous fishing camps in Farwell Canyon, from dip netting through to smoking the fish. A dozen people came out for the opening. Sandy started with an Instamatic camera at fifteen and became the unofficial chronicler of the Sugarcane community, photographing powwows, funerals, and everyday life. "It's a dying tradition," she says. "Not many people do it anymore."
• 3:55
  Casey: Twenty years at the same camps. That's a long baseline.
• 4:00
  Casey: Dan Simmons, founder of the Cow Moose Sign Project, was a finalist for the inaugural Dr. Valerius Geist Conservation Legacy Award from Hunters for BC. He was one of seven finalists from Canada and the U.S. The award recognizes people who carry on the work of a scientist who was also a hunter, storyteller, and mentor. The hand-engraved glass award arrived by Purolator on his 72nd birthday, May 26th. The photo shows him and his wife Vivian with Horsefly Lake in the background. Hunters for BC vice president Dave Ryder nominated him.
• 4:32
  Riley: A University of Cambridge-led study in Scientific Reports says comets probably didn't deliver enough hydrogen cyanide to early Earth to matter for the start of life. The team ran computer simulations of 100,000 histories. In 54 per cent of them, no comet impact delivered the chemical at a concentration useful for prebiotic chemistry. Mars comes out better in the models, but the study doesn't show a delivery happened there. The authors point to asteroids or chemistry on Earth as other routes. Astrobiologist César Menor, at the University of Alcalá, says the study should prompt a review of overly simple assumptions about extraterrestrial supplies.
• 5:14
  Casey: A computer model says the origin story was too tidy. Models are supposed to do that.
• 5:21
  Casey: A provisional object, 2026 ED138, turned up in early observations from the Vera C. Rubin Observatory in Chile. It's a candidate dwarf planet, estimated at 600 to 1,500 kilometres across. It sits about 46 times as far from the Sun as Earth does. Pluto averages about 40. It was spotted against a crowded background of stars.
• 5:43
  Riley: A study timed for Halloween looks at the chemistry of wine made from ground-up Egyptian mummies. The drink was once popular for its supposed medicinal benefits, and the newsletter at 404 Media calls it a medieval concoction. Scientists are now studying what it actually contained.
• 6:01
  Casey: A study in Science, led by Nicolás Young, a geochemist at Columbia University, suggests the next glacial period may have begun about 2,000 years ago. Then it stopped. The study points to human-driven climate change as the cause. The work focuses on the Laurentide Ice Sheet. Earth has been in its current interglacial since about 11,700 years ago. Young puts it this way: "It was just getting started, everything was normal, the next glaciation was about to happen, and yet it stopped."
• 6:29
  Riley: An ice age cancelled by people. That's a hard sentence to read on a Sunday.
• 6:35
  Riley: NASA-funded researchers say Teghaza 001, a meteorite found in Mali's Sahara in 2022, formed in Mars' crust at least 4.1 billion years ago. If that holds, it's the oldest of about 435 Martian meteorites identified on Earth. Its oxygen and hydrogen isotopes show water reached deep into the crust more than 4.1 billion years ago. The study, published in Science, says early Mars may have had habitable conditions. It does not show that life existed there. Orbital data point to 13 possible source locations in the southern highlands.
• 7:12
  Casey: Ice cores from the Guliya Plateau in northwestern Tibet were collected in 1992 and again in 2015. Their oxygen isotope patterns match closely, and the ice may be more than 128,000 years old. That would make it the oldest ice recovered from that part of Tibet. The lead author, Lonnie Thompson, says reproducibility is the point. Two cores drilled 23 years apart gave the same record.
• 7:36
  Riley: Twenty-three years apart and the same record. That's what a return visit buys you.
• 7:43
  Riley: University of St Andrews researchers, writing in the Journal of Climate, propose a link between growing ice sheets in the Northern Hemisphere and ocean changes near Antarctica. As the northern ice expanded, it changed ocean circulation and sea ice in the south. Those southern changes help draw down atmospheric carbon dioxide, which is part of how ice ages develop. The team argues cooling in one hemisphere can set off a chain reaction across the planet.
• 8:11
  Casey: Vancouver family physician Melissa Lem launched an international alliance to prescribe nature at COP17, the UN biodiversity summit in Armenia. The idea is doctors recommending time outdoors as part of care. For a patient in a rural town, the trail is the prescription. The question I'd ask is how far the trail is from the clinic, and who pays the gas to get there.
• 8:33
  Riley: Paleontologists named Paludohadros proudlovii, a plant-eating dinosaur from about 125 million years ago. The fossil was found in a Surrey clay quarry in 2001. The animal was about 5 metres long and an estimated 1.5 to 2 metric tons, but its bones show it had not reached adulthood. The fossil was donated to London's Natural History Museum, where it sat for years before a detailed comparison with other iguanodontians revealed distinguishing features. The study was led by PhD student Ricardo Sacamoto and published in the Journal of Systematic Palaeontology on October 26th. It also helped identify fossils collected from the same quarry in the 1950s.
• 9:16
  Casey: A 2001 fossil and a museum drawer. Slow science.
• 9:21
  Casey: The autumn budget, as Homebuilding & Renovating reports it, focused on energy bill relief and help for first-time buyers. Other measures could affect house building, including changes to building regulations and biodiversity requirements on brownfield sites.
• 9:37
  Riley: The Nobel Prize for controlling brain cells with light went out this month. The work behind it started with a single-celled alga called Chlamydomonas. Peter Hegemann and Georg Nagel wanted to know how it senses light, and they found a single protein, channelrhodopsin, does the job. That protein is the tool that lets scientists switch brain cells on and off with light.
• 10:00
  Casey: A study in General Psychiatry followed 87,577 adults who wore wrist devices measuring light. Over a median follow-up of 8.1 years, 741 developed dementia. People whose average daytime light exceeded 1,000 lux had a 16 per cent lower risk. Spending more time in brighter light, at least 5,000 lux, was linked to further reductions. The headline version says less than 42 minutes of bright daylight is the risk point. This is an association, so it doesn't prove daylight prevents dementia.
• 10:32
  Riley: Winter days are short here, so the question is close to home.
• 10:37
  Riley: Security teams were on high alert after researchers found eight TLS certificates with private keys weak enough to let anyone mint trusted browser and app credentials for any site on the internet. The certificates belong to India-based certificate authority eMudhra Limited. Browser makers and some major apps had blocked all eight by the next morning. Certificate transparency logs show no malicious use so far. The exposure lingers because Linux distributions and embedded and Internet of Things devices are slow to update.
• 11:10
  Casey: They signed the warning with one of the broken keys. Memorable.
• 11:15
  Riley: Next up is a local group that has been at this since 2008.
• 11:20
  Riley: Quick meta moment before we move on.
• 11:22
  Casey: Go on, I've been waiting for this one.
• 11:24
  Riley: The show now leads with local stories, and each subject lives in one place instead of showing up twice. The deep dive also has to clear a Cariboo bar before it gets picked.
• 11:35
  Casey: Which sounds great until you ask who decides what clears the bar. A bar nobody can see is just a mood.
• 11:42
  Riley: Fair, but a local lead is something you'll hear straight away. You won't hear the same story twice in one episode either.
• 11:48
  Casey: Agreed, that part is audible. I'll give it that.
• 11:51
  Riley: Then there's the repeat fix. If a kicker echoes a subject we already covered, it now gets moved beside it, so the joke lands in context.
• 11:59
  Casey: And here's my caveat. It only catches repeats it can recognize. A repeat phrased differently will still slip through.
• 12:06
  Riley: True, so it's a real improvement, not a guarantee. Worth shipping anyway.
• 12:11
  Casey: Last one. The deep dive on El Niño is now pinned by a producer for Sunday, 1 November.
• 12:16
  Riley: Which means you can't just swap it out on a whim the morning of the show.
• 12:20
  Casey: Which means someone is accountable for it, and that's the part I like. Who picked it and why should be on the record.
• 12:26
  Riley: So a pick you can trace back to a person. Hard to argue with that.
• 12:31
  Casey: I'll take it. Let's get to the rest of the show.
• 12:34
  Riley: The South Cariboo Sustainability Society has been working out of 100 Mile House since 2008, and the work runs wide. There are community gardens, an environmental film series, and education on waste reduction and ecological resilience. If you care about how a small community handles its own garbage, its own soil, and its own winter food, this is a group worth knowing. Their work is local, practical, and built on years of showing up.
• 13:03
  Casey: Eighteen years of gardens and film nights, and nobody writes headlines about those.
• 13:08
  Casey: Now the deep dive, and it starts with twenty years of photographs.
• 13:13
  Casey: If you spend twenty years watching a place, does that buy you a say in what happens to it? Or does the say belong to the people who wake up beside it every morning?
• 13:22
  Riley: Repeated observation is rare. Most field studies run a few seasons and stop. Twenty years at the same site is a baseline most agencies would trade a lot to have. So yes, it earns a voice.
• 13:34
  Casey: A voice on the data. I'm asking about the decision.
• 13:37
  Riley: Those get closer than you think when the record is the only baseline. The Tibet ice is the cleanest case. Researchers pulled cores from the Guliya Plateau in 1992 and again in 2015, and the oxygen isotope patterns matched. Lonnie Thompson's point was reproducibility. Return visits make the result believable.
• 13:57
  Casey: Nobody lives on that plateau. A researcher there gets a paper. The people beside the watershed get the closure, the flood, the lost run.
• 14:05
  Riley: Right, but that's about who carries the cost. Credibility asks whether the record holds up. A record can pass one test and fail the other.
• 14:14
  Casey: Then the decision should rest on the second test, and the first one decides who gets a seat in the room. A clean record doesn't make the monitor the one who answers for the outcome.
• 14:24
  Riley: Take the biggest example we have. Nobody lives beside the equatorial Pacific. NOAA's Climate Prediction Center says El Niño is present, is strengthening, and is likely to be strong to very strong through January to March 2027, with more than an 83 per cent chance of that. An earlier NOAA update had the chance of sea surface temperatures passing 2.0 degrees at 63 per cent. Those odds climbed all summer. The models flagged it months before the water did anything, and that's forecasting working.
• 14:57
  Casey: A probability is not a certainty. And "among the strongest on record" depends on which index you use and how far ahead you're looking. USA Today reported federal scientists putting better than 90 per cent on a very strong event for fall and winter 2026-27. Nobody's wrong about the signal. I'm asking what it tells a planner in the Cariboo.
• 15:17
  Riley: It tells a planner the event is big enough to plan around. The ocean doesn't give you certainty. It gives you lead time.
• 15:25
  Casey: Lead time for what, though. The Stuff piece out of New Zealand shows the problem. A very strong El Niño brings heightened dry spell risk to the north and east of the North Island and heavy rain to the south and west of the South Island. Same ocean, opposite outcomes, depending on which side of the map you're standing on.
• 15:43
  Riley: The pattern is regional, and "dry north, wet south" is a useful product because it names the geography. None of these sources gives a Cariboo winter outcome, and I'm not going to invent one.
• 15:54
  Casey: Good. Anyone planning a Cariboo winter from a headline is working from the wrong map.
• 15:59
  Riley: The Macleans piece quotes the World Meteorological Organization saying this El Niño will pour fuel on a warming world, with drought, heavy rain and heatwaves. The WMO's 3 September update projected a peak toward the end of 2026. A general warning is still a warning.
• 16:17
  Casey: It's also the kind of line that gets pasted onto everything. "Pour fuel" can describe a drought, a flood, or a heat dome. A warning that covers every outcome doesn't tell anyone which one to prepare for.
• 16:28
  Riley: Then the next number is the one I'd want you to defend. The 870,000 figure.
• 16:34
  Casey: I'd question it first. The University of Chicago's Climate Impact Lab first estimated about 451,000 excess heat deaths between June 2026 and February 2027. A later update came out at about 857,000 total, with roughly 373,000 in the six months after that. Press coverage rounded it to 870,000, or nearly 900,000. It hasn't been peer-reviewed.
• 17:00
  Riley: Not yet, and the first sentence of any story should say so. The team says it uses peer-reviewed methods, and the full write-up is due in a journal article. The number moved because August and September ran hotter than the model expected. A model taking in new data is doing its job.
• 17:17
  Casey: Taking in data is fine. The question is what it counts. The mortality relationship is based on annual data, which largely misses deaths brought forward by days or weeks. One expert quoted by DW argues most of the counted deaths would have happened within six months anyway. So a number that moves by hundreds of thousands in a few months answers a different question than the one a health planner asks.
• 17:40
  Riley: The method caveat belongs in the lede, not paragraph nine. But the model draws on more than 24,000 regional temperature-mortality relationships, and its job is to direct heat response, not to hand over a precise count. A planner needs to know where the heat lands first. The model says where.
• 18:00
  Casey: Ranking regions is useful. The headline still gives a count, and people remember the count. A health authority that budgets against a headline number has to explain the gap later.
• 18:10
  Riley: Then publish the range with the count. The range is what a budget can use.
• 18:14
  Casey: Same problem in California, end of October. The record tides ran from San Diego to the Bay Area. Seawater submerged streets and homes and jammed train routes. Then the explanation arrived in a stack. A full moon with the moon close to Earth. Oceanic Kelvin waves moving north along the coast, which NOAA links to El Niño. Warmer water expanding. And a months-old marine heat wave that the LA Times says had nothing to do with El Niño.
• 18:38
  Riley: The stack is the interesting part. Kelvin waves are a mechanism you can trace, and climate science can trace the chain. The Washington Post called the event a glimpse of sea level rise, and it also said the waves were relatively small, so the damage stayed limited. Both facts are true. Only one of them fits in a headline.
• 18:58
  Casey: The sea level line will get repeated. The small waves won't. "El Niño floods California" puts the blame on the ocean's weather and leaves the warming baseline off the bill.
• 19:08
  Riley: Then the bill is the question. How much of the extra water level came from the warming baseline? The stack gives you a way to ask it.
• 19:17
  Casey: Asking is different from answering. The sources don't answer it, and I'd rather say so.
• 19:22
  Riley: The split isn't in these articles. Correct.
• 19:25
  Casey: Each ingredient in that stack is a different kind of record. The moon is an almanac. The Kelvin waves come from ocean monitors. The heat wave comes from a satellite and buoy record. Nobody in the chain owns the whole picture, and nobody's job is to add it up for the public.
• 19:40
  Riley: That's a real gap, and it shows up in every monitoring project. Good data sits in several places with no one assigned to combine it.
• 19:48
  Casey: The dementia study uses the same kind of record. Researchers followed 87,577 adults who wore wrist devices that measured light. Over a median of 8.1 years, 741 developed dementia. People with average daytime light above 1,000 lux had a 16 per cent lower risk. The study shows an association. It doesn't prove daylight prevents dementia.
• 20:10
  Riley: The wrist devices are the cleanest measurement in the paper. And a dataset like that is the only way to ask the question at scale. You can't run a daylight trial on 87,000 people.
• 20:22
  Casey: Fair enough. A Cariboo winter has short days, which is why somebody here should ask whether a local light record exists. Nobody in these sources says it does.
• 20:31
  Riley: Nobody says it doesn't either.
• 20:33
  Casey: Bring it to the Cariboo. Dan Simmons founded the Cow Moose Sign Project. He was one of seven finalists from Canada and the United States for the inaugural Dr. Valerius Geist Conservation Legacy Award from Hunters for BC. He received the hand-engraved glass award on his 72nd birthday, May 26th, with Horsefly Lake in the photo's background.
• 20:53
  Casey: Who keeps the counts going when the founder stops driving out? That's the question a press release never asks.
• 20:59
  Riley: Custody is a records question. Standing is a different one. Whether a documented record counts in a decision depends on whether it's public, has a named keeper, and has written methods. Twenty years clears that bar. Five years, I can't say.
• 21:14
  Casey: Five years is the honest answer. Helen Sandy is the cleaner case. She's a Williams Lake First Nation Elder, and she spent twenty years photographing Indigenous fishing camps in Farwell Canyon, from dip netting through to smoking the salmon. The show at the Ckultenellcw Cultural Centre opened on October 29th. "It's a dying tradition," she said. Her record is local in the sense that counts. So who decides how her photographs get used, and is she at the table from the first meeting?
• 21:41
  Riley: She should be at the first meeting. A monitor with a clean method has a claim to be in the room, not just to be cited from outside it. You'd give the seat to whoever lives beside it. I'd give it to whoever holds the record. Those two can collide.
• 21:57
  Casey: They collide when the record-holder sets the agenda. The record should inform the room. It shouldn't run it. A monitor with twenty years of data brings evidence to the people who make the call. He doesn't make the call.
• 22:09
  Riley: Then we're apart on the agenda. I'd still give the record a seat.
• 22:13
  Casey: We're apart on that. Leave it open.
• 22:15
  Riley: The Surrey fossil is a useful test for custody. It was donated to London's Natural History Museum and sat there for years before a close comparison picked out its features. Fossils collected from the same quarry in the 1950s were identified later too. Records can wait a long time for someone to read them.
• 22:34
  Casey: And the meteorite from Mali's Sahara, found in 2022, went through a chain nobody prints. Desert, lab, paper. The science gets the byline. The custody gets nothing.
• 22:44
  Riley: The custody matters because the science depends on it. The Teghaza study's whole claim rests on the sample's isotopes. If the chain breaks, the isotopes don't mean much.
• 22:55
  Casey: So the piece I'd act on is small. Pick one local record. The photographs, the moose-sign counts, the pile-burn schedule in the Chilcotin that runs to January 31st, 2027. Write down who holds the originals, who can publish from them, and who answers for them if the holder moves away.
• 23:11
  Riley: A written custody line costs almost nothing. The harder question is whether the record leaves with the monitor. If you have a correction, a story tip, or a local record that should have a say, write to feedback at cariboo signals dot c-a.
• 23:27
  Casey: And ask who was consulted before anything got published. That list is usually shorter than it should be. Count something this week, and have a good Sunday.
• 23:36
  Riley: I will. Go look at the snow on the ground and see what it's doing.
