Interesting new paper documents clearly how the IAEA has been overestimating the growth of nuclear time and time again. It's the inverse of what I've documented for solar and batteries. doi.org/10.1016/j.er...

Yes, if AMOC shuts down, it may release hundreds of billions of tonnes of CO₂. You know what's guaranteed to release hundreds of billions of tonnes of CO₂ in the next few years? Our continued use of fossil fuels.

"Our results show that non-survivable conditions are occurring during present-day heat events, all of which are below 35oC wet-bulb temperature. Of concern is regular exceedances of deadly thresholds for older people directly exposed across all events. " #ClimateEmergency

The climate #litigation pico session and splinter meeting are back at #EGU26! ⚖️ We’re looking forward to another round of enriching, highly interdisciplinary talks and discussions. Based on this year’s impressive line-up of abstracts and speakers, it’s set to be a great one.

I had a feeling this was going to happen. Sad news, especially given the poor state of sea ice after this winter. Looks like we won't be getting any more data for Arctic sea-ice thickness and volume for a while from PIOMAS. See: psc.apl.uw.edu/research/pro...

New from us: how Pakistan's solar boom is dampening the impact of the Hormuz crisis on the country. Solar power allowed LNG&diesel imports to fall after the previous gas crisis in 2021-22, with the solar boom set to avoid $7bn in fossil fuel import costs this year.

Summer temperatures have strongly been influenced by circulation changes in the northern mid-latitudes. In our new study we evaluate and compare 4 statistical and ML methods that decompose trends into a "thermodynamical" and a "circulation induced" part. wcd.copernicus.org/articles/7/8...

[...] We consider it more likely that the recent rate of global warming has been larger than anticipated, exceeding both the previous trend and what would be expected when considering only the observed pattern of greenhouse gas emissions. berkeleyearth.org/global-tempe...

🌡️ 2025 was the third-warmest year on record, with a global average temperature 0.59°C above the 1991–2020 average & 1.47°C above the 1850–1900 pre-industrial level. It was 0.13°C below 2024, the warmest year on record, and only 0.01°C cooler than 2023. @ecmwf.int ⬇️

🙀 Don't forget to submit your abstract for #EGU26 And please consider submitting to our nice session on Synoptic and Large-Scale Circulation Dynamics 😻 www.egu26.eu/session/56938

Interesting update on SSTs and the state of warming:

2025 was again a severe #hurricane season with 4 major hurricanes (3 cat 5 hurricanes). In terms of accumulated cyclone energy (ACE) it was slightly above a normal season. Seasonal forecasts (including ours 🥳) predicted the ACE well this year 💪

Hurricanes feed off of warm water. Watch how quickly the eye of #Melissa collapsed as it moved onto land and over the mountainous terrain of Jamaica, and how quickly it is reforming now that it has moved back over water! I will be adding this radar loop to my earth science lectures.

To understand the climate connection to Hurricane Melissa, check out our real-time attribution page at @climatecentral.org: www.climatecentral.org/tropical-cyc... "Climate change made the ocean temperatures along Melissa's path 500 to 900 times more likely."

#Melissa is now the strongest #hurricane of the 2025 Atlantic season, and it continues to deepen. Pressure has fallen to 913mb. There’s evidence to suggest it is already even stronger than 160 mph winds. It’s possible that will be adjusted upward soon.

Vorschieben, Frauen & Mädchen schützen zu wollen, als würde sexualisierte Gewalt vor allem von Migranten ausgehen, ist so hanebüchen wie perfide. Es ist rassistisch und misogyn zugleich - und eine klassische Erzählung von Rechtsextremen, die im Übrigen nicht auf "Schutz", sondern Besitzanspruch fußt

So exhausting..

"After nearly 40 years, the Arctic Research Consortium of the United States, or ARCUS, will close September 30." "The Arctic Research Consortium of the United States funded programs that aided Indigenous communities and tracked melting sea ice, among dozens of initiatives."

#Humberto is now a Cat 5! It’s the first time in nearly a century with back to back seasons with Cat 5’s in the Atlantic. We are seeing our warmer future unfold in real-time, IMO. 1/

For years climate change research has shown that seasons would struggle with stability issues, perhaps even with less storms, but when a storm breaks through, it is much more likely to rapidly intensify to a top tier hurricane due to heated water. 2/

More systematic rapid attribution taking the expertise of health experts onboard. Heat might be a silent killer, but it is here and most excess deaths are now attributable to human-induced climate change (70% on average).

It's scary how fast the earth is warming. For a long time, the 🌊 ocean surface was warming at a slower 🐌 rate but the warming rate appears to have caught up 🐇. ➡️ In our study about the jump in SSTs, we also estimated a 0.27°C per decade warming of global SSTs (www.nature.com/articles/s41...)

This is unbelievable. The high temperature at one of Finland’s northernmost weather stations, in the municipality of Sodankylä (Lapland region) within the Arctic Circle at latitude 67.3°N, reached at least 25°C for 26 days in a row. Records date back to 1908.

🌍Across Europe, cities experienced a heatwave in late June-early July 2025. Temperatures in London reached 34.7°C, while other parts of Europe saw record-breaking heat 🧵

Small updates to the monthly climate monitoring dashboard. The biggest update is that JRA-3Q and NOAAGlobalTemp are now updated to June 2025, which show similar things to the other datasets that were already updated. 1/n www.jkclimate.fr/MonthlyDashb...

Gut integrierte 15-jährige einfach mal aus Prinzip in ein für sie wildfremdes Land abschieben. Das hat mit "geregelter Migration" allerdings überhaupt nichts zu tun. Das ist praktizierter Rassismus im Sinne der "Wohltemperierte Grausamkeit" von die Höcke vor Jahren schon schwärmte. Schämt euch!
