Reflections on COP30 Global Mutirão final decision text:

The stakes: Trump’s anti-climate agenda could result in 1.3m more deaths globally, analysis finds - Fallout from increased emissions linked to president’s ‘America First’ policies expected to most affect those in poor, hot countries #COP30 #climatecrisis www.theguardian.com/environment/...

If you have some free time today, I'm helping to host a discussion, "Antarctic Tipping Points Outlook" happening at COP30. It's hosted by the International Cryosphere Climate Initiative and you can find the talk live at www.youtube.com/@iccinet/str.... The talk starts at 14:00 CET.

So, I hate to be this guy, but as the director of Yale’s new program on attribution science (!?), uh, most of the commentary on Bluesky about Hurricane Melissa and climate change has been… not quite right

Latest update from the National Hurricane Center for hurricane Melissa right before it makes landfall in western Jamaica. Winds are 185 mph with a 892 mb pressure making it the third strongest Atlantic hurricane ever by pressure. The destruction that is about to happen is just unimaginable.

#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.

Trump says climate change predictions were made by "stupid people". I guess I'm a stupid person who now has a chip on my shoulder to make good climate science and show the real stupid people are the ones in the government who are actively trying to burn the world. www.youtube.com/shorts/hhax2...

The EPA is attempting to repeal its endangerment finding for GHGs—threatening decades of climate progress. 📢 Register by 12 Aug to testify at the virtual hearings (19–20 Aug): [email protected] 🗣️ Speak up. Science must be heard. #ActOnClimate #AGU

In case you need a podcast listen for the weekend, we recommend Beyond the Ice from the British Antarctic Survey. Check out the latest episode where Dr. Michelle Maclennan discusses the state of extreme weather over Antarctica and recent ice mass increases open.spotify.com/episode/30Tu...

Motherfucking wind farms…

A report from the Climate Working Group commissioned by the DOE is the scientific basis for the EPA's proposal to revoke the 2009 Endangerment Finding. This report, written by well-known climate skeptic scientists, is absolutely insulting to read from a science writing perspective. 🧵

🚨 The U.S. oil rig count just suffered its fastest collapse since the pandemic. From January to July 2025, rigs dropped 13.7%, the steepest 15-week plunge in five years. This isn’t just about oil, it’s about inflation, jobs, energy security, and the global economy. (Save this thread)

New paper alert 🚨 Our work on the representation of extreme precipitation events within kilometer-scale Earth system models is published. On a personal note, it's the first paper I've written that doesn't focus on Antarctica! More details below 🧵 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

After a brutal start to the Alps melt season from an early season heatwave, we'll get a small reprieve with a series of cyclones drawing down cold, moist air from the north. In the highest elevations, there could be widespread accumulation of around 50 cm by Wednesday.

A large part of the western North Slope of Alaska with official forecast high temps over 90F today and tomorrow. This is borderline unprecedented if it happens. There are no weather stations in those 90F+ forecast areas though. So verification will basically be impossible. @alaskawx.bsky.social

Intense melt at high elevation and lack of freezing make juxtaglacial lakes to form as already shown at Mer de Glace near Punta Helbronner! Here is an other example at 3430 m on Saas Fee Glacier! ❄️🧊🌊 (already existing in 2023, not shown on Swisstopo) www.linkedin.com/posts/thomas...

New paper in ERL! We study the importance of resolution for the representation of climate extremes. We use a new generation of km-scale models to show that many important details about temperature and precipitation extremes are hidden at CMIP6-like resolutions. doi.org/10.1088/1748...

Our #CopernicusAtmosphere aerosol optical depth forecast initialised on 11 June showed a complex mixture of aerosols over Europe in recent days with smoke transport from Canadian wildfires interspersed with a plume of Saharan dust. See the latest charts at atmosphere.copernicus.eu/charts/packa...

To the scientists who shared their work and kept pressure building against the Trump Admin for 100 straight hours: thank you for your relentlessness. We owe you a future of climate safety.

Following @jonathanwille.bsky.social 's recent post about an #atmosphericriver / #heatwave in West Antarctica, I did some digging in ERA5 to look at the drivers and impacts of the event. Sharing here for those who might be interested 🌨️🌡️👀

Yesterday's devastating #glacier collapse erasing the Swiss village of Blatten still leaves me speechless... The high mountain areas are adapting to ever increasing temperatures. It's time to wake up! When, if not now? This is not far away but right here... pic: Pomona/A. Amherd

New paper shows through a modelling experiment that reduced Antarctic sea ice may cause a positive feedback loop where the atmospheric response drive even further sea ice loss agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Here’s how Trump’s war on science is going. NSF funding is at the lowest level in decades. We’ll lose knowledge, generations of scientists, and US competitiveness. www.nytimes.com/interactive/...

Wow: concerted effort by NY governor, Norwegian government, US senators and congressmen, labour groups... results in Trump withdrawing stop work order on Equinor's offshore Empire wind project. 🔌💡 www.equinor.com/news/2025051...

West Antarctica has been excessively warm the past month and an upcoming atmospheric river will likely lead to further extreme warmth in the coming days #antarctica #extremeweather 🧵

In today’s climate, #atmosphericrivers play a major role in bringing snowfall to #Antarctica. Have you ever wondered how that might change in the future? Out today, our new study on the future frequency and precipitation impacts of Antarctic atmospheric rivers: www.nature.com/articles/s43...

OK, this is wild. In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them. It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*. What the HELL? 1/

Woke up in a Bizarro world where destroying unknown ecosystems suddenly became “scientifically backed”. Sadly the Trump goons have control of the NOAA social media which only a few weeks ago was still informing us about climate disasters.

@dwallacewells.bsky.social suggests that for many, "the terror has subsided, giving way to a sort of heavy acquiescence." "But it’s in the short run, just decades, that the pathways to what we once identified as relatively livable futures will be made or broken." www.nytimes.com/2025/04/23/o...

NEW: @noaa.gov downplayed a stark new CO2 record. Instead of posting a public-facing web story, agency officials opted for sharing the report via social media posts that glossed over the findings' significance. Story for @cnn.com www.cnn.com/2025/04/22/c...

I could spend hours going through the global emissions map. This feels revolutionary in visualising GHG emissions in a way everybody can understand. Especially if further research is done to verify the emissions data from Climate TRACE. www.forbes.com/sites/we-don...

Snow depth in #Grächen (1605 m ASL, Valais, Switzerland) reached 60 cm this morning - the maximum of the whole winter period 2024/25. On 14 April 1989 a stunning 105 cm were recorded. More charts: myweather.ch/winter/GRC#s...

📚 Paper alert! 🧪 Thrilled to share my first scientific publication as a first author! "Svalbard's Record‐Breaking Arctic Summer 2024: Anomalies Beyond Climatological Warming Trends" is just out in Geophysical Research Letters, open access. agupubs.onlinelibrary.wiley.com/doi/full/10.... 🧵(1/5)

BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency. Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

US commerce department is cutting funds to Princeton Uni. for climate modeling because it, “promotes exaggerated and implausible climate threats, contributing to a phenomenon known as “climate anxiety,” which has increased significantly among America’s youth”. www.commerce.gov/news/press-r...

1) Fox News is for real not showing stock-market ticker during this week's collapse. 2) Its economic news is "strong jobs report." 3) Every time I've checked in today, the coverage has been "illegal immigrants committing new crimes." This is state propaganda, on a par with North Korea or PRC.

Finally a "What If" that should capture the attention of the meteorologists and climate scientists. www.youtube.com/watch?v=WH4g...

EXCEPTIONAL COLD IN ANTARTICA -75.5C reached in the French-Italian station of Concordia: This is just 0.6C above the world record of lowest temperature ever recorded in March.

At a quick glance, 2025 could be making a serious push to break the 2012 record sea ice minimum. 😟

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back. This was the largest political gathering in Denver since Obama in 2008. Also bigger than the 2024 DNC. And the largest ever rally in Bernie’s career (and obviously, mine too).

Damn, I was really hoping we would get through the spring without a major dust event. Besides making the mountain snowpack ugly, these dust events help accelerate summer snow and glacier melt. Expect significant dust deposition starting Friday in the Alps and lasting through the weekend 😔

New paper alert! Great study reveals that high-resolution modelling is important for capturing rainfall and surface melting response from Antarctic atmospheric rivers. link.springer.com/article/10.1... @marlenkolbe.bsky.social sky.social @ruthmottram.bsky.social

The French just introduced the next-generation TGV. The low-carbon transition comes with 5G at 350km/h.

Temperature anomalies exceeded 10°C above the 1981-2010 climatological average in February 2025 from Svalbard toward the North Pole! 🔥 Data from @copernicusecmwf.bsky.social ERA5 reanalysis.

This really gets to my core believe on why MAGA is so attractive and Democrats remain so unpopular. Until NIMBYism is defeated, housing in many Democratic cities will remain unaffordable and people will leave. It just has to become easier to build things (my non-expert take).
