One thing I've been stressing is that, if Hormuz traffic remained stopped, the monumental oil supply shock will manifest as sharp price spikes in wealthy nations that sap disposable incomes In poorer countries, the shock will manifest as outright physical shortages.

Lovely story on the BBC about iceberg a23a, which has given us decades of fun but is now nearing its end… Really enjoyed talking with Mark Poynting about this one-time behemoth. www.bbc.co.uk/news/resourc...

Academic writing: why use utilize when you can use use

Between 1992-2025, large areas of the grounding line of #Antarctic glaciers have retreated. The largest changes have occurred in W. Antarctica, where grounding lines have retreated 10-40+ km, driven by incursions of warm water masses along deep bathymetric troughs www.pnas.org/doi/full/10.... ❄️🧪🌊

Whew. All signs are increasingly pointing to a significant, if not strong to very strong, El Niño event. I'll have more to say in coming weeks & months, but for now I'll just say that this is increasingly likely to become a major regional-to-global climate driver in 2026-2027.

That's like a little over five Rhode Islands

Sigh. This is the directorate that funds all of the earth, ocean & atmosphere research at NSF.

The fact that food waste is not a polarizing issue might be the reason for slow progress. Baffles my how much food people waste and how little they think about it ...

Wow! 37.9” (96 cm) of snow has fallen in Providence, Rhode Island, pulverizing the previous all-time single-storm snowfall record by over 9”.

Blizzard of 2026, Rhode Island

...RECORD SNOWSTORM FOR PROVIDENCE RI... AS OF 1 PM, THE SNOWFALL TOTAL AT RHODE ISLAND T.F. GREENE INTERNATIONAL AIRPORT WAS 32.8 INCHES. THIS BROKE THE RECORD FOR THE GREATEST SINGLE SNOWSTORM ON RECORD, WHICH WAS 28.6 INCHES SET DURING THE BLIZZARD OF `78, ON FEBRUARY 6-7, 1978.

The fundamental premise behind AI-enabled cheating is that coursework is merely busy work, because your'e just doing it for professors. We would never say that showing up for football practice is merely busy work because you're just doing it for your coaches.

lol

The work is original? ....and that doesn't answer the question

This seems like a great moment to talk about the importance of science communication! Science communication matters because it connects scientific research with people, giving folks information they need to make informed decisions about everything from health to hazards.

The Dawlish - Teignmouth railway line feels like the absolute front line of climate adaptation in Britain (a test we are not passing so far). And yet somehow, somehow, this article manages to go in-depth on the problems with the line without mentioning the climate once. The sea is literally higher!

Yes, it's been cold in the Northeast US, but really nothing out of the ordinary. Dec-Jan temperatures:👇

This is just nonsense, the New Yorker helping Anthropic out with some marketing. An LLM cannot plan, it doesn’t think, it’s not reasoning, it generates a sentence in a moment.

Is there a live or regularly-updated version of this figure comparing actual CO2 emissions with SSPs/RCPs? From: www.carbonbrief.org/explainer-th...

I know it’s intentional but we should stop calling everything AI, lumping useful machine learning techniques for science with large language models that tech companies are trying to cram into everything.

We had a paper ourselves debunking the original argument that a weaker gradient leads to a wavier jet and more cold extremes. doi.org/10.1029/2024... 4/

I've seen several Big Climate Accounts™ post about how the recent winter storm was made worse by climate change. It's a convenient narrative. s But what is "worse"? Colder temperatures? More snow? More freezing rain? Is there any primary literature supporting the idea of worse snowstorms? 1/

We are not even remotely ready to fight this.

I love how this graphic is totally unhelpful for determining whether you're going to get 30 inches of snow or half an inch of ice.

In a warming climate, extreme cold can still occur. The occurrence of an extreme cold event does not mean that climate change caused it, nor does it mean climate change isn't real. But on sufficiently long timescales, extreme cold events are occurring less often. doi.org/10.1126/scia...

AI folks inventing shiny “tools” for issues that already have low-tech, tried&tested solutions. "[AI agents] could be more creative, like an artificial flower or tree. This “smart” classroom plant could change colour based on the collective mood of the class" 😒 macleans.ca/the-year-ahe...

Does anyone know of a Python code to create this beautiful dataviz?

I honestly thought December was way colder in the Northeast than what the numbers indicate. Seven mild Decembers in a row really messes up your perception...

2025 goes down as the ~3rd-warmest year on record (based on ERA5). Like in 2024, every single day this past year was warmer than the average of even the most recent reference period (1991-2020).

Paleoclimatologist Jessica Tierney recently published a global temperature record covering almost the past half-billion years. According to her model, 50 million years ago, inland temperatures approached 122 degrees Fahrenheit. www.quantamagazine.org/climate-extr...

Scientists are supposed to be happy when their predictions are skillful, right? Why do I not feel happy?

Do not cite an academic paper unless you’ve read it

I've put together my predictions for 2026 and 2027 temperatures over at The Climate Brink. I expect 2026 will likely end up similar to 2023 and 2025 at ~1.4C, while 2027 will likely be considerably warmer (conditional on El Nino): www.theclimatebrink....
