Hundreds of Scientists “Vehemently Oppose” U.S. Effort to Purchase Greenland - Eos About 350 scientists scientists have signed a letter condemning U.S. President Donald Trump’s efforts to acquire Greenland.

“President Trump’s talk of ‘buying’ Greenland is not only an affront to Greenland’s autonomy but also a dangerous distraction from the urgent work of addressing environmental change impacts to US citizens,” the letter reads. eos.org/research-and...

We've come a long way in our understanding of the Antarctic Ice Sheet history, even while we have a ways to go to know how fast future changes are coming. I'm lucky to be a part of John Anderson's group. See story on his career: naturalsciences.rice.edu/milestones-s...

A clear summary of much of what we have learned about Thwaites Glacier, and what we still need to learn.

The NBP has finished her last USAP cruise. Not the outcome we’ve been hoping to see. I’m of course glad that researchers are being supported by substitute vessels. But, it’s not clear how this will work in the long run.

University of Houston students had the chance to participate in a marine mapping short course that included field work and hands on exercises.

Just after publication, an NSF spokesperson responded to @science.org confirming the plan: "NSF is terminating the lease of the research vessel Nathaniel B. Palmer in FY 2026. NSF has also begun the process to identify vessels and partnerships to support marine science. "

We're updating the story.

Thanks to @voosen.me for helping spread the word about this potential major blow to U.S. polar science. @carlosmoffat.com and I are grateful to all the people who have shared their concerns by signing our letter. Keep reaching out to protect the USAP icebreaker---and science in general.

Are you a scientist that wants to support the Antarctic marine research community? And coastal access? And access to USAP stations? See below to join 120+ of our peers in fighting to keep the NBP.

We will circulate the letter to NSF’s acting director, to our colleagues in the NSF's Directorate of Geosciences, including the Office of Polar Programs and the Division of Ocean Sciences.

Did you know there is a plan to terminate the lease of the NB Palmer, the US icebreaker supporting Antarctic science?

I’m sorry this is happening to you but so glad to see that my lab/department/university is not unique in the struggle to obtain basic HVAC services without extensive email exchanges over several weeks. Good luck.

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

How bad will it be? Catastrophic.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.

But, this is the WH's *proposed* budget.

Speak up now before it is too late.

Spot on, Rob. Pouring days and days and days of work into something without knowing that it will be considered is not something any of us want to do. Obviously you know the mess we face. It is hard to know what to do.
