A few notes here: - region spans 10-20°N, the main development region in the eastern North Pacific, *not* the ENSO monitoring region - it's very warm in the ENP MDR, but that warmth tends to be shallow as captured by Argo float profiles - SST gradient NW of the ENP MDR is still present (but shifted)

Megathread about responding to new OMB grant funding rules (feel free to add/link more!) I was collecting these for me, but figured I'd round 'em up for everyone 🧪 What's the problem? arstechnica.com/science/2026... elizabethginexi.substack.com/p/summary-of...

Proposed new US funding rules: We can cancel any grant at any time

Peer review now optional, political staff would screen grants for forbidden topics.

NEW: NSF has been funding research at a fraction of its historic rate. Last week, the agency finally began distributing money to its directorates and is now likely to pick up the grantmaking pace. But these allocations also amount to substantial cuts across the sciences. My reporting:

Delays have kept new NSF grants to a trickle — that could be about to change

The agency is finally ready to distribute a spate of new grants, but it is also preparing substantial cuts to areas such as biological and social sciences.

Writing and deleting posts of outrage, grief, stress, and anger. This is all so horrific.

Attention folks in the weather, climate, disaster, wildfire, and Earth science communities: NSF has just published a new "Dear Colleague" letter inviting feedback (by Mar 13) on the proposal to dismantle the National Center for Atmospheric Research (NCAR). www.nsf.gov/funding/...

The National Science Foundation sign on our Eisenhower Av building is now gone. The NSF mural in the foyer is removed and torn off in sheets. We were supposed to celebrate the 75th anniversary of the agency in May 2025. That never happened.

The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

They’re stealing from us. They are stealing from us and we have to put a stop to this. This cannot stand.

Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

We should study this change as scientists. Monitor the intended outcomes of NSF-funded research: Discovery (probably measured by proxy via publications and by expert elicitation), training graduate students, and outreach/public-facing events. Then compare outcomes pre- and post these changes.

Alondra Nelson@alondra.bsky.social · 8mo ago

🧵 NSF is reducing external review requirements and eliminating routine expert panels, citing staff shortages that this administration implemented. This change expands program officer authority. But the solution to flawed accountability isn't less public accountability.

NSF - Forced reorg - POs down ~ 40% (DRP, most rotators not renewed, retirements) - Forced move (and we have to pack and clean) to a building with no furniture, little to no conference space for panels, inadequate 🛜, …) I personally love the boxes they gave us for packing. “Details matter” 🙃

I got my PhD in a geography department and the DDRIG program was crucial to funding the final push of measurements I needed for my dissertation. This sucks.

Kristina Killgrove@killgrove.bsky.social · 8mo ago

NEW from me - NSF cancels grant scheme for social science research. Seems the NSF quietly archived ALL calls for DDRIG grants in the SBE directorate. This is a massive blow for PhD students wanting to do cutting-edge social science research. 🏺🧪
