The anti-woke lot know that air conditioners ARE heat pumps ... right? www.theguardian.com/environment/...

Another way of slicing it - for event as rare as this one (~1 in 40 years), the hottest-day French national-average temperature would be: - 1.0 °C hotter in a 2 degreeC world - 2.6 °C hotter in a 3 degreeC world So, the national average extreme warming runs about ~1.6× faster than global mean temp

Just spent a solid 30 seconds wondering why Vector Auto Regression (VAR) was a trending topic

Recent French national average temperatures: - impossible in a pre-industrial world, - about 1 year in 40 years in a 1.5C world - 1 in 10 years in a +2 °C world - 3 degree world - happens every other year interactive/method/maps here (également en français): benmsanderson.github.io/futureevent/

What is the future of summers in England? Our choices matter. A high-emissions future will commit our children and grandchildren to live in a world where the summers of 1976 & 2025 are cold. A global net-zero emissions future means that we can stabilise the climate & those summers will be normal.

A US federal judge has ruled against the Trump administration, preventing it from handing off a piece of the National Center for Atmospheric Research (NCAR). See how we covered the battle over NCAR as it kicked off in court last month. go.nature.com/4u3jvIV

Score one for NCAR/UCAR.

NCAR just won in court! A US district judge in Colorado has prohibited NSF from taking #NCAR apart, specifically in spalling off its supercomputing center in Wyoming. storage.courtlistener.com/recap/gov.us... Our earlier story on this and why it matters: www.nature.com/articles/d41... 🧪

We have a new preprint this week. When CO2 emissions stop, warming in the pipeline is controlled by two big opposing effects - thermal response to energetic imbalance *and* carbon sink evolution. We assess their roles in the flat10MIP ensemble /thread/ egusphere.copernicus.org/preprints/20...

One datacenter. 9GW. powered entirely by natural gas turbines is about 31 million tonnes of CO2 per year. About the same as Switzerland. www.theguardian.com/us-news/2026...

Universities that run the National Center for Atmospheric Research want to keep it from being dismantled

Hi everyone, in the course of NorESM development for CMIP7 - we've had need to do some rapid benchmarking and diagnostics. To this end, I've made a couple of tools which might be useful for the wider community - python ports of ncview and CMAT. /thread/

Hi everyone, gridded data for the flat10MIP project is now open and public on the Norwegian Research Data Archive. Research using these data for understanding carbon-climate feedbacks, including climate commitment and reversibility is super relevant for AR7-WG1. archive.sigma2.no/dataset/flat...

So... now we can breathe again. Let's talk about ScenarioMIP. The final version is now up on GMD - and there's some changes since the first draft. /THREAD/ gmd.copernicus.org/articles/19/...

This is a horrifying threat of genocidal war crimes. The lives of civilians and service members alike are at stake here. Congress must stop this war and remove Trump from the White House.

The enlightenment realised. Simultaneously futuristic and ancient, the Mesa lab is a building from an alternative timeline, one where we built monuments to science rather than gods or money or power. It betrays scale - with no relatable features on the outside, it merges with the mountain.

One reason LLMs are a limited way of understanding the world is because the world is only partly defined in terms of texts. - As an autistic person I am constantly confronted by how text and speech are incredibly unreliable guides to navigate the world.

Here's we are, inconsiderately consuming food to support our inefficient biological neural networks “it also takes a lot of energy to train a human ... It takes about 20 years of life – and all the food you consume during that time –before you become smart.” www.theguardian.com/technology/2...

Kid this evening: "Why do people talk about "the 90s" so much, that's like, a date in the future"

The science is, apparently, fine. We just decided it's beyond our remit to "protect" the "environment"

The federal government is setting itself up to be on the wrong end of the biggest lawsuit in history.

Next time someone asks you about energy and land use, maybe remind them that the ~35 million acres that currently grow corn for ethanol in the US could produce ~15 PWh per year of electricity from solar photovoltaics. That's ~3.5 times more than *total annual generation from all US power plants*.

The Methane spike in the early 2020’s has been explained in two new studies. A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land are to blame. www.science.org/doi/10.1126/...  www.science.org/doi/10.1126/... #methane

wow, this event looks interesting! www.civitasinstitute.org/events/power...

A past criticism of Variable Renewables Energy (VRE) from wind & solar was that their power was intermittent & thus unreliable. But the drop in battery storage cost has ushered in the age of firmed renewable energy (FRE). Renewables with storage are displacing import and fossil fuels. 🧪🔌💡☀️💨💧🔋

NSF has just put out a call for 'concepts' on how to evolve weather forecasting & computing related parts of NCAR. The word climate *does not appear* in this document, but it does ask for ideas on "Ownership of the NSF NCAR Mesa Lab building for private use" Call for input by March 13....

Attention folks in the weather, climate, disaster, wildfire, and Earth science communities: NSF has just published a new "Dear Colleague" letter inviting feedback (by Mar 13) on the proposal to dismantle the National Center for Atmospheric Research (NCAR). www.nsf.gov/funding/...

Oh wow - this is fascinating. At one point in the emails, they got copilot to review the DOE report for them - and copilot told them they were stretching the truth... library.edf.org/AssetLink/18...

People - don't get ChatGPT to write your job application letters. When you read 100+ of these things in a row - they all sound identical, with generic references to the job ad. You can pretty much guess the prompt they used. The easiest way to stand out is to be your imperfect, brilliant self.

These dynamics are clearly happening - seemingly creating larger oscillations / stupider decisions over time. But even if the stock market resets, there is also cumulative damage to America's international standing which is not reversed when trump steps back from the brink.

These things can be simultaneously true: 1- We can't meaningfully address climate change if the world is held hostage by authoritarians who are actively seeking to undermine international agreements. 2- decarbonisation is a critical part of gaining leverage against those authoritarians

It feels like the necessary response of the civilised world to rising authoritarianism might be defined by this speech, if others follow. Principled, but strategic. Intelligent, but forceful. Multilateral, but not complacent in the role of existing institutions.

If the last decade has taught Europe anything, it should be that reliance on fossil fuel imports is a strategic liability which will be exploited. Climate aside, decarbonisation is security. www.theguardian.com/world/2026/j...

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...

You have to block them immediately. The full nuclear. They are only here to make folks angry, and that can’t happen if we lock them out.

If there's a silver lining to this madness, perhaps it can at least bring wider Europe together with a sense of common identity

Worth noting that the EU’s reluctant tariff concessions to the US, agreed between VdL and Trump at Turnberry, haven’t yet been approved by the European Parliament. There’s no realistic prospect of the US deal going through now.

Called my Congressppl’s office to ask them to oppose any DHS funding that does not rein in ICE. I also asked them to oppose any State or Defense funding that doesn’t include the NATO Unity Preservation Act, which would block the use of funds for military or economic aggression against a NATO ally.

A rare bit of good news from the US. House republicans seem to be pushing back against Trump's huge proposed cuts to science. NSF, NASA, NOAA - all look set to be near flat, or - for DOE - even a slight increase. www.economist.com/united-state...

Preprint out today in ESDD. SRM's biggest risk is us. 'Peak-shaving' is a best-case scenario, with strong governance and international cooperation. We propose a framework for messier geoengineering futures, which look more like, you know, the news. /1 egusphere.copernicus.org/preprints/20...

I had a great time presenting at #AGU25! Grateful for the support of my advisor @kimcobb.bsky.social and amazing @ncar-cgd.bsky.social scientists. NCAR makes my research, and so much other vital climate science, possible.

I was wondering when AMS was going to say something publicly. www.ametsoc.org/ams/about-am...
