Amplified warming accelerates deoxygenation in the Arctic Ocean - Nature Climate Change Rapid warming of the global ocean and amplified Arctic warming will alter the ocean biogeochemistry. Here the authors show that Atlantic water inflow, and the subsequent subduction and circulation, is...

‘It’s a nightmare.’ U.S. funding cuts threaten academic science jobs at all levels “There is a lot of pressure to essentially leave the country or not pursue research,” one Ph.D. student says

I can't stress enough how close U.S. science is to the cliff.

"Numbers released in May by the National Science Foundation (NSF) indicate that if Congress approves the cuts to the agency proposed by the White House, the number of early-career researchers it supports could fall by 78%" (@science.org)

NSF Unidata Pause in Most Operations NSF Unidata Pause in Most Operations

Due to the current gap in funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program is pausing most operations effective 12 May 2025. Nearly all staff will be furloughed until funds from our existing NSF grant become available. For more information, see buff.ly/d2TC1Oy

Netto, neutral, egal?

Auf die richtigen Worte kommt es an: in der CO2-Entnahme-Debatte ebenso wie in der Gesetzgebung. O. Geden + CDRmare-Co-Chair A. Proelss haben vor diesem Hintergrund einen Blogbeitrag zum Verhältnis von Klimawissenschaft und Klimapolitik im Recht geschrieben. verfassungsblog.de/klimaneutral...

Because no one spends as much on science as the US does, destroying NIH, NSF, NOAA, NASA, EPA, USDA, USGS, etc. is leading to a brain drain, but it's not to other countries but rather from science. This senseless destruction of US science will hurt the US and the world for a very long time.

Trump proposes unprecedented budget cuts to US science Huge reductions, if enacted, could have ‘catastrophic’ effects on US competitiveness and the scientific pipeline, critics say.

US President Donald Trump’s proposed budget for fiscal year 2026 calls for unprecedented cuts to scientific agencies that, if enacted, would deal a devastating blow to US science, policy specialists say.

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.

Exclusive: NSF stops awarding new grants and funding existing ones US science funder also plans to screen grant applications for compliance with ‘agency priorities’.

🔔BREAKING🔔

The NSF has frozen all research grant awards—cutting off life-saving science midstream and demanding ideological screenings for future funding.

This is censorship disguised as oversight.

National Climate Assessment Authors Are Dismissed by Trump Administration The Trump administration told researchers it was “releasing” them from their roles. It puts the future of the assessment, which is required by Congress, in doubt.

“We've arranged a society based on science and technology, in which nobody understands anything about science and technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces.”

~ Carl Sagan

Remember: NOAA is not its social media accounts. Do not let the takeover of NOAA communications take away your support of the real NOAA and the very real scientists behind it. The administration would want nothing more than for us to stop supporting our science agencies 🧪
