The US has some of the world’s best climate scientists (and more of them than anywhere else) & has contributed disproportionately to understanding the climate system. It’s idiotic for the US to withdraw from the UN Framework Convention on Climate Change & the IPCC but it’s on brand for this regime.

So the word from UCAR (NCAR’s managing entity) is, essentially, “This is news to us!” news.ucar.edu/133054/ucar-... 🤔

It took a while for the centers, labs & groups bringing together scientists, researchers, and communicators on climate to realize Bluesky was a thing. But once they did, they arrived in droves. Here are the first 100 early adopters. Give ’em a follow! Day 6 of my 20 Days of Climate Starter Packs.

The annual Arctic Report Card is now out for 2025. It discusses recent changes in the #Arctic, extreme events, and broader human/environmental impacts. This is the 20th anniversary edition. 20 years of rapid change. + Report arctic.noaa.gov/report-card/... + Summary arctic.noaa.gov/report-card/...

Time to repurpose #AGU25 as a mass mobilization in support of NCAR, NSF, NOAA, NASA, USGS, DOE BER, and the Congressional power of the purse.

The same week as #AGU2025, Vought and his cronies come after one of the world’s premier weather and climate research institutions. Absolutely disgusting www.ucs.org/about/news/t...

New paper out in @science.org from the LegacyNet. Functional plant diversity and fertilization impacts on yields were compared in a network of sites across the globe. Our colleague Sebastian Meyer hosted the Freising site, allowing us to follow it closely for many years. doi.org/10.1126/scie...

Nevermind the administration disappearing people off the streets or murdering Caribbean fishermen or shutting down agencies illegally or declaring war on trans people or openly accepting bribes, Dems picked a fight on health care and couldn't even find the spine for that," the NOAA employee said 😳

Goddard Space Flight Center’s science center is slated to close due to the government cuts. Thank you Space.com for covering this. www.space.com/space-explor...

There are more than 100 marine research institutions in the United States and they’re under threat from Trump’s attack on science funding. 🌊

it’s essential that scientists, decisionmakers, & end users codevelop forecast tools & information. Close integration ...would focus scientific innovation on user-defined needs of what is useful and actionable, allowing scientists to build tools that meet those needs. eos.org/opinions/sci...

New in the Climate Data Store (CDS): the ERA5-Drought dataset, with monthly meteorological drought indicators across accumulation windows from 1, 3, 6, 12, 24, 36 & 48 months from 1940 to today. Supports both deterministic & ensemble products on a 0.25° grid. More info ⬇️​

Future changes in irrigation will reduce dry-heat stress (without reversing GHG trend) and will substantially amplify moist-heat stress (strengthening GHG trend). New study @natcomms.nature.com led by Yi Yao @hydr-vub.bsky.social and @usyseth.bsky.social www.nature.com/articles/s41...

Attribution of vegetation change to climate change: here we compared vegetation time series to simulations from a process model forced with observed and counterfactual (detrended) climate data. Trends in climate necessary for the model to emulate vegetation trends www.nature.com/articles/s41... 1/3

Speaking of, cool to see NASA listed as one of the Webby Awards most iconic companies in internet history today!

I'm happy to share a paper in Science Advances that makes the case for a weak land carbon sink, drawing upon JPL and Chloris biomass time series. To close the budget with a net land sink of 0.8 Pg C/y from 2000-2019, we propose increases in the ocean sink and decreases in fossil fuel emissions.

🦋🌱 Most people care about #biodiversity, yet we often underestimate how concerned others are about its loss. This “pluralistic ignorance” can silence people, weaken action, and make ambitious policies seem less popular. In a new paper, we outline a research agenda to study and reduce this gap (1/2)

Deforestation is responsible for nearly 75% of dry season rainfall reduction in the Amazon rainforest since 1985, according to a study in Nature Communications. go.nature.com/3I2xPzr ⚒️ 🧪

If you kept meaning to let the USDA know what you think of their reorganization plan but never got a round tuit, here's one here. #usda subscriber.politicopro.com/article/2025...

Interested in a small home solar install but my god it’s like a feeding frenzy out there as soon as you show any interest and the DOE resources put a target on your back, resulting in constant phone calls and texts. There must be an easier way to connect with local reputable companies. #solar

Because destroying the US is not enough, Trump is using tariffs, visa restrictions, and trade deals to pressure other countries to abandon climate goals and increase fossil fuel use, further destroying the world and the future.

Trump issued an EO trying to take away collective bargaining rights from orgs like NASA And NOAA by claiming their primary function is "intelligence, counterintelligence, investigative, or national security work." It's bullshit and another attempt at hurting workers and consolidating power.

The @ametsoc.org responds to the the regime's Department of Energy #climate report: "We identify five foundational flaws in the [...] report. Each of these flaws, alone, places the report at odds with scientific principles and practices." www.ametsoc.org/ams/about-am...

Hey Folks...You may start seeing social media sites and a website for Climate.us If you see it, follow and share. It is legit and has some amazing, credible people behind it trying to plug leaks in the climate science world. Trust me on this one. More is coming....

It's hard not to lose hope when every day we watch the nastiest people on Earth bludgeon our beloved institutions. But every bit of successful opposition matters, and we have a responsibility to ourselves and future generations to reverse course as fast as possible and save what we can.
