Humanity heating planet faster than ever before, study finds
After removing natural effects (El Niño etc), warming rose from ~0.2°C/decade (1970–2015) to ~0.35°C/decade in the last 10 years; fastest since 1880.
At this pace, 1.5°C could be crossed before 2030.

Des poussières désertiques en provenance du Sahara ont survolé l’Hexagone cette semaine ! Un phénomène connu des régions méditerranéennes.

Job alert! @northumbriauni.bsky.social is hiring a researcher to investigate tipping points in Antarctica's ice sheets – funded by ESA's Climate Change Initiative 🧊🌍
📍 Newcastle, UK | 14-month position
📅 Apply by 13 March 2026

This persistent ridging/blocking will continue pushing subtropical/midlatitude moisture deep into East Antarctica throughout the week. A large expanse of +20C anomalies are expected. Not as extreme as March 2022, but noteworthy in the longevity of this heat event.
The result is a prolonged period of extreme temperatures and melting along coastal areas. For instance, Cape Denison on the coast has been at 2-3C the past couple days
And finally another atmospheric river forecasted for March 1st.
And today on the 23rd
And Feb. 20
Then another on Feb. 18.
The first atmospheric river was Feb. 12
East Antarctica has been the epicenter for unusually persistent blocking and atmospheric river landfalls that have resulted in some extreme high temperatures. From February 12-March 1, I've noted 5 distinct atmospheric river events observed/forecasted over Wilkes Land.
This is one of the bigger disaster amplifications I’ve seen from climate change. Putting this more bluntly, many more people had their livelihoods and homes destroyed because we can’t stop burning fossil fuels. I hope they sue the oil companies for damages

🔔🚨 New Publication Alert!
Research has shown that the Antarctic Ice Sheet is a climate tipping element.
We found: it’s not one — it’s many.

Always good to keep things in perspectives despite the headline news from the Trump administration about keeping coal alive.
I am impeaching Secretary Kristi Noem, who is an incompetent leader and a disgrace to our democracy.
She wreaked havoc in the Chicagoland area and has brought her reign of terror to Minneapolis. One of her rogue ICE agents shot and killed an innocent woman today. It must come to an end.
Antarctica had its warmest year on record. That seems fucking bad. 🔥🔥🔥

If you are spending the holidays with family and would like to talk to some climate skeptics, then I would show them this chart. Few things hit harder than the disappearance of the white Christmas they experienced in their childhoods.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.
🌧️ New study: the deadly Indonesian floods were made worse by climate change.
Present-day conditions in similar events are now up to 10% wetter (+7 mm/day) and windier, boosting extreme rainfall.

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

You can also find a recording of the talk later on the same Youtube page.
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.
