"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/

New study on the impact of aerosol forcing on heat wave attribution by Florian Kraulich ( @sebastian-sippel.bsky.social and me ) www.sciencedirect.com/science/arti...

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...)

Germany is straying from its decarbonisation path. Renewable energy expansion is not matching stated targets and planned gas capacity expansion risks locking in emissions. Explore how Germany could get back on track to 1.5°C 👇 UPDATED TODAY: 1p5ndc-pathways.climateanalytics.org/countries/ge...

Iraq blackout: "Electricity demand jumped, triggering a failure in transmission, as temperatures in parts of the country soared to as high as 50C (122F), with millions of people joining the Arbaeen pilgrimage." 🎁 link www.bloomberg.com/news/article...

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...

New paper: Explaining and predicting the Southern Hemisphere eddy-driven jet @marleneclimate.bsky.social www.uni-leipzig.de/en/newsdetai... "The researchers found that 50 percent of the observed shift in the SH jet stream is directly attributable to global warming." www.pnas.org/doi/10.1073/...

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!

Excellent new paper on recent warming: "Here, we find that emissions reductions in East Asia have contributed up to 0.05 °C/decade since 2010, explaining a large fraction of the observed increase of 0.06 °C/decade over the same period, after filtering out the effects of interannual variability."

Deutschlandweit war es im Jahr 2025 von Anfang Februar bis Ende Mai seit Aufzeichnungsbeginn 1881 noch nie so trocken. Das ist das Fazit eines neuen Berichts des DWD zur klimatologischen Einordnung der Trockenphase 1. Februar – 31. Mai 2025 in Deutschland. Link zum Bericht: t1p.de/yc2hb

Updated fossil CO2 emission estimates from @robbieandrew.bsky.social Based on the latest data, we estimate fossil CO2 emissions went up 0.9% in 2024. Listen to his presentation here (starting about 8:55): cicero.oslo.no/no/arrangeme... 1/

For 2025, we again expect high hurricane activity in the Atlantic. Most seasonal forecasts (including ours) estimate an accumulated cyclone energy of more than 120 ACE. Thanks to seasonalhurricanepredictions.bsc.es/forecast for collecting and publishing the forecasts!

Czechia was hit pretty badly by drought and bark beetles a few years ago, but the forest carbon uptake has recovered somewhat in the last couple of years.

If the data holds, it would imply a rather substantial decrease in the land sink (on the assumption the ocean does not change much). It will be an exciting (or depressing) Global Carbon Budget 2025... 3/3

Preliminary data suggests that the global average increase in atmospheric CO2 concentration in 2024 will be a record. Not just a little record, but 25% higher than the previous record. (This is the global average, as opposed to Moana Loa) gml.noaa.gov/ccgg/trends/... 1/

Very interesting reconstruction study! I would not have expect such strong long-term (5k years) trends in TC frequency. At the end of the time series the effect of global warming becomes apparent.

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 water vapour emitted into the stratosphere by the Hunga Tonga-Hunga-Ha'apai volcanic eruption in January 2022 continues to influence climate. The MLS data for stratospheric water vapour is now only available a few days per month, but we can still continue the "tape recorder"

And you thought it was all just for the good of society?

Imperialism and colonialism has resulted in significant scientific and technological disparities, hampering a just and sustainable future in the Global South. Testani et al (w/ our own Julia Mindlin) on how to balance Earth science careers in such an unequal world: www.nature.com/articles/s43...

People need to plan for climate risks. The research is there, but the usability for stakeholders can be limited. We introduce the reversal of the impact chain approach for actionable climate information that allows linking local risk levels directly to GHG emission. www.nature.com/articles/s41...

More compounding hot and dry events in Europe—not only stronger driver, but also amplified causal link strength! It’s such a pleasant journey starting from Como summer school back to 2022. Many thanks to all my excellent coauthors and dear friends www.nature.com/articles/s43...

On The Climate Brink: Stop emissions, stop warming: A climate reality check This is a crucial point because it determines how much warming is already "locked in" and effectively unavoidable. The answer is very little warming is locked in. Also, this is our 100th post! www.theclimatebrink....

The Atlantic #hurricane season is over. It has been a highly active season with an ACE index of 162 (Accumulated Cyclone Energy). This outcome lies well within the range of our June #forecast of 133-220 ACE. Other forecasting groups expected a higher activity with an average of 211 ACE

Overshoot makes matters more complex and leaves a long-term legacy for example in relation to the strength of the Atlantic Meridional Overturning Circulation. We can thus confidently say that a climate after overshoot is different from one that had avoided it. 9/

Understanding the consequences of potential overshoot above the 1.5°C warming level has been the focus of the PROVIDE project and the work by a great group of interdisciplinary authors has just been published in @natureportfolio.bsky.social www.nature.com/articles/s41... Here’s what we found: 1/

Based on our seasonal #hurricane #forecast model we expect a highly active season in 2024 with an estimate of 160 ACE (accumulated cyclone energy). Other research institutes (ECMWF and CSU) forecast even higher activity
