@metoffice.gov.uk ‘s 'State of the UK Climate' report is out today, with some key findings:

🌊UK sea level is rising faster than the global average
🌡️extremes are becoming the norm
🥇record breaking weather events are becoming more frequent
🔥the last 3 yrs have been in the UK's top 5 warmest on record

The Secretary of Commerce's new policy requiring his personal review of all NOAA contracts over $100,000 is directly harming American science. 🧪

How do I know? Because this morning, twelve of America's rising leaders in climate science (including myself) were furloughed.

Termination of OAR’s Climate Laboratories and Cooperative Institutes (-$102,292, -204 FTE/ -216 Positions) –NOAA will continue to support high priority ocean and weather research programs in NOS and NWS. In coordination with the requested terminations for Weather Laboratories and Cooperative Institutes (see OAR-10) and Ocean Laboratories and Cooperative Institutes (see OAR-19), NOAA will close the Atlantic Oceanographic & Meteorological Laboratory (AOML) in Miami, FL; the Air Resources Laboratory (ARL) in College Park, MD, Idaho Falls, ID, and Oak Ridge, TN, as well as a nation-wide network of soil moisture sensors; the Chemical Sciences Laboratory (CSL) in Boulder, CO; the Geophysical Fluid Dynamics Laboratory (GFDL) in Princeton, NJ; the Global Monitoring Laboratory (GML) in Boulder, CO, Utqiaġvik, AK, Mauna Loa, HI, Hilo, HI, Big Island, HI, American Samoa, and the South Pole; the Pacific Marine Environmental Laboratory (PMEL) in Seattle, WA; and the Physical Sciences Laboratory (PSL) in Boulder, CO.

What a tragedy this is even being proposed on paper... 💔

Excellent post by @dinahvp.bsky.social‬ on the plan to devastate NOAA research, with quotes from @franklinjamesl.bsky.social @wxmanms1.bsky.social. "Only a small fraction of NOAA Research would remain and be transferred to the NWS, including portions of the weather, tornado and technology research."

Screenshot from NSIDC that says: "Dear Colleague: The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) learned yesterday that the Department of Defense (DoD) will stop processing and delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025. The SSMIS data are used as input for the following NSIDC DAAC-produced data sets, which will therefore stop processing no later than 30 June 2025:"

Awful. More horrible science news

National Science Foundation Staff Booted From Headquarters - Eos Staff at the National Science Foundation (NSF) were notified on 25 June that the agency’s office space, located in Alexandria, Va., will be taken over by Department of Housing and Urban Development (H...

I know there’s a lot of news right now but this is really crazy. They’re booting the National Science Foundation out of its newish building with no plans for where 1800 people are going to go.

Great initiative by Bill Gates. The global economic uncertainty and wars are hitting poor countries the most. Hope this initiative would provide the required investment.

Excited to share new research in the Journal of Geophysical Research:Oceans with @andyhogg.bsky.social, @navidcy.bsky.social, Ryan Holmes, and @hemant-khatri.bsky.social on how the North Atlantic Oscillation impacts the basin's subtropical and subpolar gyres: doi.org/10.1029/2024... 🌊

Trump Administration Halts Harvard’s Ability to Enroll International Students

Trump just revoked the ability for foreign students to enroll at Harvard. Every foreign student, which is in the thousands, enrolled for next year at Harvard will not be able to continue studying if this isn't challenged in court.

Exclusive: NSF faces radical shake-up as officials abolish its 37 divisions Changes seen as a response to presidential directives on what research to fund

RIP American science: NSF faces radical shake-up as officials abolish its 37 divisions, layoff staff, and terminate more funded grants.

Carbon majors and the scientific case for climate liability - Nature A transparent and reproducible scientific framework is introduced to formalize how trillions in economic losses are attributable to the extreme heat caused by emissions from fossil fuel companies, whi...

Interesting study showing economic losses due to emissions by individual fossil fuel companies.

Such studies aimed at quantifying economic losses and emissions by individual sectors, companies and countries are needed to determine accountability for global warming.

White House Proposal Could Gut Climate Modeling the World Depends On Potential funding cuts for NOAA and its research partners threaten irreparable harm not only to climate research but to American safety, competitiveness, and national security.

"The possible elimination of the lab, called GFDL, in concert with potential cuts to other NOAA operations, threatens irreparable harm not only to global understanding of climate change and long-range scenarios for the planet but to the country’s safety, competitiveness and national security."

That's definitely on my reading list.

Looks like Trump has vowed to destroy everything, including oceans, climate research, trade, freedom of speech.

Stand Up for NOAA Research – The Time to Act is Now The AMS is a global community committed to advancing weather, water, and climate science and service.

"To envision the disastrous impact of this plan, one only needs to see what NOAA research has provided to the U.S. taxpayer and imagine where we would be without it."

"Now is the time to reach out to your elected representatives."

"Stand Up for NOAA Research" - @nwas.org and @ametsoc.org statement

That's insane.

It's even worse than removing the grant funding for university research (in groups like mine at UC Irvine). NOAA labs and cooperative institutes collect the climate data we use, develop the predictive weather and climate models, and train the students we hire.

This demolishes U.S. climate research.

White House Plan Calls for NOAA Research Programs to Be Dismantled (Gift Article) A Trump administration budget proposal would essentially eliminate one of the world’s foremost Earth sciences research operations.

Critical yet often overlooked is that NOAA's Oceanic and Atmospheric Research maintains vital long-term monitoring programs like the CO₂ Keeling Curve that, while essential, often struggle for funding from agencies like NSF that prioritize hypothesis-driven research over sustained observation.

It's sad to see CIMES funding cut at Princeton. It has been an incredibly successful research program.

Trump imposes tariffs on uninhabited Heard and McDonald Islands near Antarctica Australian prime minister surprised after remote external territories – including islands home to penguins – targeted by US president

The big question is - will the penguins now impose reciprocal tariffs?

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and April by looking at the decadal average line positions.

Monday ice update - #Arctic sea ice extent is currently the 2nd lowest on record (JAXA data)

• about 400,000 km² below the 2010s mean
• about 840,000 km² below the 2000s mean
• about 1,330,000 km² below the 1990s mean
• about 1,760,000 km² below the 1980s mean

Columbia University’s Concessions to Trump Seen as a Watershed (Gift Article) Threatened with losing $400 million in federal funding, the university agreed to overhaul its protest policies and security practices.

What troubles me about Columbia, an institution I was associated with for 34 years, is that the actions of the Trump administration serve as a test case for future pressure on other universities, many of which lack the resources to fight. Things are gonna suck for academia in the US.

A scorpion labeled Trump on the back of a frog labeled Columbia University, from the story in Lev Nitoburg's 1933 novel The German Quarter.

This won't end well.

Red colored line graph time series of global atmospheric methane abundance from January 1984 through November 2024. Methane abundance is measured in units of parts per billion. Current levels are 1941 ppb. A seasonal cycle is visible on the graph. There is also decadal variability and a long-term increasing trend.

Methane (CH₄) is a potent greenhouse gas. Here are the latest monthly observations... 🧪⚒️

November 2024 - 1940.75 ppb
November 2023 - 1931.75 ppb

Storms kill 16 across the U.S. as tornado risks are set to peak Numerous significant tornadoes are expected Saturday afternoon and evening, with the highest risk across several states in the Deep South, forecasters say.

It would be good if there was a government agency tasked with warning people about these things.

Suppression of climate data built up by decades of hard working scientists dedicated to measuring and understanding planetary health. Removing facilities that measure climate change will not change US exposure to its catastrophic consequences 🔥🌀🌊🌪️
