Oxford, the longest running continuous weather station in UK history, with temperature observations stretching back to 1815, has preliminarily broken its maximum temperature record for May yesterday by OVER 3ºC with a temperature of 33.7ºC. Unprecedented in its 211-year history.

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...

The debate continues: Multidecadal variability in the Atlantic mostly forced, multidecadal variability in the Pacific mostly internal agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Is more always better? Not when it comes to planting trees to cool the climate 🌲🌍 Our new study in @commsearth.nature.com shows that strategic reforestation can achieve the same cooling with half the land www.nature.com/articles/s43... #Reforestation #ScienceforPolicy

Gonna keep posting about this. Dismantling NCAR is stupid and dangerous; doing it as payback to the governor of Colorado is idiotic.

AGU has a Congressional email and call script up on NCAR:

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.

Friends at NCAR, we're with you. @ncar-ucar.bsky.social is a trailblazer in community modelling driven not by idealogy, but by open science. We share all our code, thoughts, ideas. These can't be shut down. We'll fight and find every mechanism to support the ongoing CESM community.

📢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! :)

We are convening an EGU 2026 session on the large-scale atmospheric circulation in past, present and future climates! Always a fun and vibrant session, abstract deadline is 15th Jan 💨🌎 meetingorganizer.copernicus.org/EGU26/sessio...

Online chatter suggests that the DOE Climate Change (Denying) Working Group has been disbanded and the report will be withdrawn. 😂 Seems that violating FACA and the Information Quality Acts have consequences. Not seen any official announcement though.

We are looking for an Assistant Professor (tenure track) in the area of Soil Chemistry. Please spread the word! Application deadline is September 30. ethz.ch/en/the-eth-z...

This is a bit technical, but I'm updating my table of TCR/ECS values for CMIP6 models, and I need to find info on these models: "AWI-ESM-1-1-LR", "CAS-ESM2-0", "CMCC-CM2-HR4", "E3SM-1-1", "E3SM-1-1-ECA", "EC-Earth3-Veg-LR" , "ICON-ESM-LR". Anyone? thx!

For years, I've long said that climate.gov's team of remarkable communicators (& their amazing blogs, which were accessible but did not "dumb down" the science!) was NOAA's best (& most cost effective!) public-facing extreme #weather / #climate education effort to date. This will be a huge loss.

Reminder: call for abstracts for the CMIP Community Workshops. Latest developments in models & approaches, reflections on CMIP6, explorations on CMIP7, etc. In particular for those related to climate emulators, I encourage you to check the session 29. All info here: wcrp-cmip.org/event/cmip26/

Can't believe it's already hour 47/100! Dr. Olivier Pauluis is currently talking about why the atmosphere moves. Join us here: wclivestream.com/watch/

The village of Blatten in Switzerland is partly buried by the collapse of a glacier which melted because our greenhouse gas emissions warmed the climate. Another reminder that choosing to not invest enough today to reduce emissions means far greater costs for society in the long term.

Heads up on this vital 100 hour streaming marathon on the value of weather and climate expertise as National Weather Service struggles with staff shortages and reduction in service www.forbes.com/sites/marsha...

New research from CIRES Fellow Kris Karnauskas found that widely-used estimates of upwelling along the equator in the Pacific Ocean are far off — the water is rising much faster. @oceansclimatecu.bsky.social @colorado.edu @ametsoc.org Read the story: cires.colorado.edu/news/pacific...

I’m looking forward to EGU next week, where there will be a large representation from the ETH Climate Dynamics group! A 🧵 of all the exciting research our group will be sharing. I’m also looking forward to catching up with everyone going to EGU! (1/11)

We published a signal-to-noise analysis of AMOC observations in GRL. TLDR: Direct observations (RAPID) of the AMOC do show a decline in line with climate model projected weakening (~1 Sv/decade) but the noise is still very large in comparison to the signal. Paper: doi.org/10.1029/2025...

Looking forward to presenting the results from our study at #EGU25 in Vienna next week! The rough reality: How forests reshape tropical circulation and hydroclimate 📅 Tue, 29 Apr, | 🕑 10:45–12:30 CEST | 📍 Hall X1, X1.43

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. www.science.org/doi/10.1126/...

The AMS is temporarily opening its career services to all who need them, regardless of membership status, and offering dues waivers and meeting registration fee reductions for those impacted by job loss due to changes in the government. Read more: bit.ly/4gRiHAk

IPCC scenarios are projections, not predictions. "The future has not been written. There is no fate but what we make for ourselves." We get to decide what the world will look like in 2100. gmd.copernicus.org/articles/13/...

🚨Postdoc in Climate Dynamics at ETH Zurich🚨 We are hiring a postdoc to work on understanding projected future changes in the atmospheric circulation and climate. The scope is broad, with flexibility to work on questions aligned with your interests/experience. jobs.ethz.ch/job/view/JOP...

Promoting papers feels a bit strange this week considering everything going on, but I am excited about our new paper showing a larger influence of Gulf Stream anomalies on the atmospheric circulation over Europe in models that resolve weather fronts (1/6) t.co/5tVgIBGuJr

To optimize climate models, how do we prioritize between resolution & ensemble size, between physical param. development & incorporating AI? In a perspective paper out this week, Tapio Schneider, Ruby Leung, and myself argue we need a balanced approach: t.co/Vm87lbjrPz

Less than a week to submit an abstract for #EGU24. If you work on understanding the contributions of internal variability and forced responses to historical or future climate change and climate impacts (e.g., using large ensembles), then please consider submitting to our session!

Can climate models reproduce observed trends in the tropical Pacific SST gradient? Does their ability to do so (or not) have implications for climate sensitivity? In a new paper led by Maria Rugenstein and @ShreyaDhame, we show … 🧵 doi.org/10.1029/2023...
