Great to see the US colleagues joining forces to organize the nomination process for US scientists in the #ipcc AR7

And a really handy link thst has both nomination forms and a drop down menu showing contact details for the focal points

Finally up on the #ipcc webpage - open until ~ 1st week of April

Last night, the #IPCC agreed the outlines for the 3 WG reports of #AR7, and invited work to start with author nominations (call likely out some time next week) and joint LAMI in Q4 2025 in Paris (tbd) - it's a go, finally! However publication schedule tbd further at P63 in Peru

Visiting the impressive facilities of the CMA's Zhejiang Meteorology for #ipcc outreach event - China's disaster risk prevention and response services are exceptional. With DOGE is dismantling NOAA, seeing this provides some solace

Yesterday, my federal agency (NSF) experienced a sudden and mass firing of over 10% of our workforce. My own Division lost 20% of its staff. In the blink of an eye, we lost many brilliant scientists, dedicated civil servants, and parents/spouses/caregivers who no longer have a paycheck. The firing was completely arbitrary, with no actual plan to achieve "efficiency" but instead just picking off anyone with the fewest job protections. I grieve for my former colleagues and extend my hand to be of help however I can. I still have a job - not based on my abilities but simply because my status makes me harder to fire. But who knows what comes next. I'm hoping this assault on science and government is just a passing storm, but even then the damage has already been devastating - careers broken, research disrupted, and resources wasted. Science is the goose that lays golden eggs - unleashing human ingenuity and systematic thinking toward discoveries that transform our society for the better. Public science funding creates space for research that may not have immediate applications but will yield dividends down the road. Unfortunately, right now the science goose is being strangled and those golden eggs are being lost. Our society will be poorer, sicker, and weaker as a result.

Scoop: U.S. delegation pulled from key U.N. climate science meeting The IPCC meeting in China is slated to determine the content in the group's next series of reports.

‼️The US-based @ipcc.bsky.social technical support unit (TSU) for Working Group 3 Co-Chairs has been terminated, and the US won’t be attending next week’s IPCC meeting where the AR7 chapter outlines will be approved.

#ipcc AR7 scoping meeting day 2 - the beauty of working for the IPCC TSU: wonderful colleagues from all over the world! Here with our Chinese WGI TSU colleagues

so excited - tomorrow, the #IPCC scoping meeting for AR7 www.ipcc.ch/event/ar7-sc... will finally start. we have been preparing this for months with the TSUs, the WG Co-Chairs and Bureaux. First participants already wandered the halls while we held the 68th meeting of the Bureau www.ipcc.ch/bureau/

Hej everyone. arrived in Kuala Lumpur for the #ipcc AR7 scoping meeting. Really excited about the opportunity to engage with experts across working groups! Of course, social media policy is strict and we can't share content - but I may drop a few photos, e.g. of #micromobility

Coal, Oil and Gas Going into Extra Time The Narrative of Abated Fossil Fuels Threatens to Undermine the Paris Climate Targets

What Happens After the World Reaches Net-Zero Emissions? Many aspects of Earth’s system, including global temperatures, may feel the effects of warming even after net zero is achieved, according to a new study.

"The uncertainty is itself an argument for reducing emissions as quickly as possible. If any warming can be expected to follow after reaching net-zero emissions, countries will want to accelerate their plans and supercharge efforts" www.bloomberg.com/news/article...

Meeting the 1.5°C Climate Goal Will Save Millions of People, and It's Still Feasible People already suffering from climate change are beseeching world leaders to hold global temperature rise to 1.5°C, even if we surpass that threshold temporarily

Great piece on 1.5C! But important to note: the push to focus on "more realistic" targets (like < 2C) is not dominated by the global North - LMDC group actors, like China, India or Saudi Arabia, also advocate for <2C to increase available carbon space

Understanding critical issues around #CCS will help finding common ground @COP28_UAE: e.g. scarce storage capacities need to be left for #CDR, not #fossilfuels aka. "abated emissions". Explainer👇

@robinlamboll.bsky.social and colleagues have just updated their carbon budget for 1.5C, and it's not cheery reading. My commentary for NCC talks about why it needed updating, what it means and whether the IPCC should be doing this calculation at all... rdcu.be/dpQha

I also really like the cake - it's a slightly different notion, and a very accessible image

No such thing as a free lunch

Hydrogen Ladder Version 5.0 So my lovelies, here it is: Version 5.0 of the Hydrogen Ladder! This is the first major update since Version 4.

Since he's unfortunately not here himself (yet), I'm just dropping this here - favorite concept of all times! That much for H2-ready boilers
