To be clear, this "High-warming" scenario is where we're headed under our current emissions trajectory. Climate action is often presented as too expensive. But what's actually expensive is huge stock market losses and people losing their retirements. www.ortecfinance.com/en/about-ort...

It's always refreshing to read analysis of a real risk that few are talking about. A new report from Ortec is more clear-eyed than most about institutional investors' dangerous exposure to climate risk. "A failed low-carbon transition could wipe 33% off pension fund returns worldwide by 2050".

It’s not often I strongly disagree with every other person quoted in an article in which I am also quoted. But I have to admit that’s true of this @businessinsider.com story that came out Sunday. www.businessinsider.com/malibu-ocean...

This confusion is part of why the obsession with global average temperature bothers me. Climate change is operating at the extreme ends of the distribution (temperature, precipitation, etc.) If you just look at the average you’re missing the biggest impacts.

In our spring report about the upcoming wildfire season we projected abnormally high risk in several parts of Western Canada 🇨🇦 But the fires so far have surpassed my expectations. Here's our latest update on wildfire risk in Canada www.deepskyclimate.com/blog/wildfir...

Pleased to see Deep Sky Research cited in this great article on an under-reported topic 🌽📉 “We’re losing 120 calories per person, per day, for every degree of global warming.” www.forbes.com/sites/felici...

This may be very millennial of me. But a magazine feels like "real news" in a way that online articles still don't. So it was a bit shocking to see my research cited in TIME Magazine the other day.

I was quoted in this article on UK heatwaves 🥵 The one we felt in Toronto last week was not much fun, but those temps in the UK would feel even worse bc of the infrastructure. We're all going to need some investment in climate adaptation!

Great article from @pilitaclark.bsky.social out today on the potential for climate financial shock. www.ft.com/content/9e5d...

We're all getting used to warmer temperatures 📈 In the UK you hear a lot about the heat wave of 1976 but those temps would not have been out of the ordinary today. I'm quoted in this article which takes a broader view: uk.news.yahoo.com/heatwave-197...

Thanks @climateeconomics.bsky.social! 🔥 Only saw this now.

The Trout and Buck fires burning in New Mexico right now are precisely in the darkest red part of Western NM that our report identified. Evacuations have been ordered and a state of emergency declared. Thinking of all affected. www.deepskyclimate.com/blog/insurer...

Great summary here of our research on wildfire risk and home insurance in California. "No safety net: Insurance starts to go away" www.resilience.org/stories/2025...

1. This chart is awesome. 2. This conclusion is terrifying: There is around half a degree of warming today that is [still] “hidden” by aerosols.

Update: bill signed! In the sea of horrifying news out there (to which I definitely contribute) it's nice to see an actual policy win for people and healthcare. Thanks @warren.senate.gov for supporting this. bsky.app/profile/warr...

The @betakit.com wildfire guide is excellent. And I don't just say that because they cite Deep Sky Research 😏 betakit.com/wildfire/

New Deep Sky Research report out today: "Insurers Retreat as 2025 Wildfire Risk Reaches Dangerous Levels" Insurance companies are abandoning homeowners in high risk wildfire areas 🏚️ And fire risk in 2025 poses serious threat 🔥 Some findings in thread 🧵 www.deepskyclimate.com/blog/insurer...

Holy moly! 2025 is now ranked 18th for total burn area in Canada's 43-year data record. There are still 3 more months in the fire season...

Working on a wildfire report right now and this smoke concentration data explains the haziness out my window 💨 Smoky conditions are going to be hanging around for a while. Wildfire report coming soon 👀

We need more of this. Well done @climatescibreak.bsky.social "If the difference between 1.5 and 3° doesn't sound like a lot it's because we need new numbers: f***ed, totally f***ed, dead?"

Now there are over 200 active fires and over half are 0% contained or out of control. Saskatchewan and Manitoba have both declared states of emergency and people are being evacuated in BC now too. Very worrying.

Pleased to see our hurricane research cited in this Time magazine article alongside @climatecentral.org I used it in my research, but the "hundred-year" storm concept is confusing when the goalposts move as quickly as they are. The article explains it well. time.com/7289719/hund...

This is off topic but my little brother is fighting to stop private equity companies from gutting healthcare in Oregon. He's Rep Ben Bowman's Legislative Director. And they're winning! @tinakotek.bsky.social just needs to do the right thing 👀 www.wsj.com/articles/ore...

There are almost 200 active fires burning across Canada right now and *93* of them are “0% contained” or “out of control” 😳 Thinking of folks in Manitoba and hoping this isn’t the start of another 2023-scale wildfire season. cwfis.cfs.nrcan.gc.ca

The latest satellite data tracking global sea levels came online today from CNES/AVISO 🌊 144 mm may not sound like a lot but climate scientists have shown -- and you can see for yourself if you look closely -- the rise it's accelerating 📈 www.deepskyclimate.com/data-dashboa...

This means no more updates to this chart. Devastating

Thanks I hate it www.theguardian.com/us-news/2025...

Another record daily temperature on Friday: 1.61 degrees above the pre-industrial average. 2025 global temps remain worryingly high.

We’re back in record daily temperature territory. Thursday was the hottest April 24th in modern decades. It reached 1.56°C above the pre-industrial average. The previous record holder was 2020. www.deepskyclimate.com/research

Again: the first major financial impacts of climate change are showing up in the home insurance market. I was cited in this article - which is good despite my name being wrong - on wildfires and the developing home insurance crisis in California. www.insurance.com/home-insuran...

Fascinating paper that confirms what we should already know: Our financial system is not somehow bubble-wrapped to withstand the effects of climate change swirling around it. We will all lose money because of climate change. 🧵

We just hit a new global temperature record. Thursday was the hottest April 10th in modern decades. It was 1.67°C above the pre-industrial average. (The second highest was 2024 at 1.65°C.) www.deepskyclimate.com/data-dashboa...

🚨Very bad news! Annual global CO₂ increase of 3.75 ppm! @climate.noaa.gov had to extend its y-axis by 1 ppm for the first time. More and more of the CO₂ we emit stays in the atmosphere (Airborne fraction). Likely because the Land Sink (biosphere) is decreasing, increasing the Atmospheric Sink

Always channeling his calmness in the face of climate crisis. Such resilience, bravery despite the terrifying data on the monitor next to him.

Repeating to myself that climate does not equal weather watching snowflakes falling out my window on April 10. Climate change is a hard problem to communicate about.

If you thought I was going to be left out of the posting scary line charts bonanza on here today... And hot take: this is scarier. www.deepskyclimate.com/data-dashboa...

The @climate.noaa.gov data on billion dollar weather disasters is critical for understanding climate change. Really hope we don't lose this dataset. www.deepskyclimate.com/data-dashboa...

Global oceans continue to be very, very warm. So far 2025 is in second place only to last year. The direction of that little red line will tell us a lot about the health of our oceans and where we're headed. www.deepskyclimate.com/data-dashboa...

🚨 Tuesday hit a new temperature record for that date. 🚨 It was the hottest March 20th in modern decades. 2025 is off to a worryingly hot start. Have a look for yourself: www.deepskyclimate.com/data-dashboa...

These two side-by-side really tell the whole story. Check out our Climate Dashboard! It runs daily to track the data of climate change: deepskyclimate.com/research And please let me know what you think!

Our atmosphere has an ~18%~ higher CO2 concentration today than when I was born. It takes quite a leap of faith to think that would have no impact. And emissions are still increasing. www.deepskyclimate.com/research

Check out this thing I've been working on the past few weeks. It's a dashboard tracking the data on climate change, updated daily. Closing your eyes doesn’t make a problem go away. www.deepskyclimate.com/research

Sadly this is panning out exactly as expected. Highest fire risk in years leading to devastating wildfires. Don't get distracted by questions on source of ignition. This was ~inevitable~ with these levels of fire risk. All fuelled by climate change. www.nytimes.com/2025/03/14/u...

More climate weather disasters means more of my face on the news so it's a real double whammy. I talked to CBS News in Texas about growing wildfire threat. Climate change causes hydroclimate whiplash which fuels out of control wildfires. www.cbsnews.com/texas/news/c...

Did you know there was water rationing in Bogotá last year? That's how bad drought has been. South America is being hit hard by the climate crisis but it rarely makes the news in US/Canada. I was quoted in this article about climate impacts in South America. nearshoreamericas.com/year-of-drou...

Investors with long time horizons (like pension funds) should be ~way~ more worried about climate change than they are. One day their financial risk models will seriously consider climate risk but that day has not come.

Canada has (finally) announced plans for a high-speed rail project between Montreal-Ottawa-Toronto. As I wrote this Fall, it's a critically-important project: And it's not too late to do it right. www.thestar.com/opinion/cont...

~Another~ new paper suggesting climate sensitivity is higher than we thought. When climate scientists are "stunned" / "mystified" by rates of warming, maybe it's because we've had a crucial input wrong: climate sensitivity. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

The new Hansen paper argues climate sensitivity is actually 4.5°C - at the very high end of current estimates. If he's right, warming will accelerate very quickly from here. Whether you agree or not it's much safer to act like he's right than to hope he's wrong.
