Some reflections after returning back from a conference at which I and 20,000 colleagues learned that the Trump administration intends to dismantle #NCAR. This outrage should not happen. deepconvection.substack.com/p/save-ncar

If you are in the US and you would like to send a message to your elected representative about the proposed dissolution of the National Center for Atmospheric Research, @agu.org makes it easy with a template here: agu.quorum.us/campaign/151... #AGU25

Science has named the seemingly unstoppable growth of renewable energy worldwide as the 2025 Breakthrough of the Year. Learn more about this year's #BOTY and other big advances in science: https://scim.ag/493Tpgx

Devastating and dangerous blow to the weather and climate community tonight, as 20,000 earth and space scientists meet at #AGU25. New @ucs.org statement from @carlonimbus.bsky.social on the Trump administration plans to dismantle @ncar-ucar.bsky.social: www.ucs.org/about/news/t...

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

NCAR is quite literally our global mothership. Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources. Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet. Unbelievable.

In the world we live in today, that is 1.3C warmer due to our continued burning of fossil fuels, the extreme rainfall leading to disastrous flooding in many parts of Asia is up to 50 to 160% more intense - new @wwattribution.bsky.social study www.worldweatherattribution.org/increasing-h...

🌡️ November 2025 was the third-warmest November on record globally, keeping 2025 on track to be the second- or third-warmest year recorded. The global three-year average temperature for 2023–2025 will likely exceed 1.5°C above pre-industrial levels for the first time.  Read more ⬇️

The latest #climate update from Copernicus shows that 2025 is on course to be: - joint 2nd warmest year, tied with 2023 and behind 2024 (warmest year) - November 2025 was the 3rd warmest November globally For more: climate.copernicus.eu/copernicus-2... 🌏🌡️⚒️🧪🌊

🗻🏘️On 28 May 2025, twenty million cubic meters of rock and ice buried the medieval village of Blatten and nearby settlements in the Swiss Lötschen valley. The disaster underlines the impact of climate warming on people and heritage. 👉Read the latest comment on this: www.nature.com/articles/s43...

And now we know that the volume of #Arctic sea ice also dropped to a record low in October (zacklabe.com/archive-2025/). It's been a historic fall in the #Arctic, which is already a season of rapid climate change. Not good.

Great start of @ipcc.bsky.social #AR7 main reports with 1st ever joint first lead author meeting (#LAM1) of Working Groups I, II & III! Fantastic atmosphere! Amazing organisation of technical support units, with >600 participants! We also had a get-together of the Switzerland-based participants!

Honoured to open @ipcc.bsky.social's first Lead Author Meeting for AR7 in Paris today. Congratulations to 600+ authors on their appointments—this marks the beginning of our scientific assessment. Thank you to France for generously hosting this historic meeting. 🔗 bit.ly/4ir09cC

Latest #Climate data shows a podium finish for 2025 We are in the decade where the 1.5°C limit is likely to be exceeded, highlighting the accelerating pace of climate change Average global temperature for 2023–2025 is likely to exceed 1.5°C, the first three-year average to do so 🌡️🌏🧪⚒️

Why did GHG emissions rise? 50% of the increase was from land-use change, primarily due to more fires during El Niño. We expect this to drop in 2025. LUC is also very uncertain. All other main regions, except EU27, with rising emissions in 2024. 2/

"Science is being destroyed across many agencies" say federal researchers. For my latest @nature.com piece, I spoke to 19 different scientists across EPA, NOAA, NIH, NASA, and USGS to document how science is being dismantled across US federal agencies.

Future changes in irrigation will reduce dry-heat stress (without reversing GHG trend) and will substantially amplify moist-heat stress (strengthening GHG trend). New study @natcomms.nature.com led by Yi Yao @hydr-vub.bsky.social and @usyseth.bsky.social www.nature.com/articles/s41...

Congratulations to #IPCC Bureau Member, @soniaseneviratne.bsky.social on the German Environmental Award from German Federal Environmental Foundation - the first Swiss national to win the prestigious €500K Award. A powerful recognition of her global impact in land-climate science. 🌍👏 #ETHZurich

Following Hurricane Melissa's devastation, Jamaica’s decade-long effort to build financial resilience will be tested. Its $150 million catastrophe bond, triggered by a storm’s low pressure and path, will provide quick relief. Jamaica’s model may serve as a guide for other climate-vulnerable nations.
