📢Submit to our EGU session!📢

We are organizing a session at EGU 2026 in Vienna, with a focus on climate sensitivity, radiative feedbacks and the pattern effect!

If you work on anything related to climate sensitivity, we'd love to have you! 🥳🥳🥳 Submit soon! :)

Interesting point thanks – but note the railway line to Geneva is 25 kV (French standard).

I haven't submitted to AMS journals in a few years – they're not fully open access so we're not allowed to use grant funds towards their fees. We do have an institutional agreement with AGU journals though.

There’s so much happening right now, I thought I’d put together a running thread on the dismantling of #climate and research and knowledge infrastructure in the United States 🧵

Exclusive: NSF stops awarding new grants and funding existing ones US science funder also plans to screen grant applications for compliance with ‘agency priorities’.

🔔BREAKING🔔

The NSF has frozen all research grant awards—cutting off life-saving science midstream and demanding ideological screenings for future funding.

This is censorship disguised as oversight.

Can climate models reproduce observed trends?

The answer can be challenging. Our new review paper in Science Advances led by Isla Simpson and Tiffany Shaw @drshaw.bsky.social discusses challenges and ways forward in confronting climate models and observations.

NOAA firings hit the birthplace of weather and climate forecasting Dismissed researchers were improving severe weather predictions

Hi - I'd like to share this story of what is happening at NOAA GFDL, where some of my colleagues and I worked until the mass firings at NOAA last week.

"...the birthplace of weather and climate forecasting"

Have we already breached the 1.5°C global warming target? Although the climate goals set by the Paris Agreement are based on the long-term average temperature, one year of high temperatures might be a sign that the 1.5°C threshold has already been reached

Redrawing the global warming stripes.

In a new paper led by Sebastian Sippel published in Nature today, we show that the early 20th century global ocean surface temperatures and thereby global mean surface temperature were warmer than previously thought.

Here is why 2024 is virtually certain be the warmest year on record and first one above 1.5°C 👇

Data released today by Copernicus Climate shows:

🌡️ It is now virtually certain that 2024 will be the warmest year on record. It is also virtually certain that the annual temperature for 2024 will be more than 1.5°C above the pre-industrial level, and likely that it will be more than 1.55°C above.

Timeseries of GISTEMP annual temperatures with uncertainties from 1880 to 2023 and including an estimate for 2024 using YTD temperatures. The 2024 estimate is clearly above and distinct from all previous years and straddles the '1.5ºC above the late 19th C' line.

With the (belated) September data now in, the updated prediction is that 2024 is almost certain to be a new annual surface temperature record, and possibly by more than 0.1ºC. 50% change of exceeding 1.5ºC above the late 19th C.
