William Bond, defender of grasslands In recent years, one of the loudest ideas in environmental policy has been that trees are the planet’s universal remedy. Plant enough of them, in enough places, and carbon will be soaked up, water wil...

"Bond’s work leaves behind an inconvenient lesson for an era of climate urgency: that speed is not a substitute for understanding, and that good intentions, applied without care, can erase ancient worlds as efficiently as neglect." A beautiful tribute to William Bond. Forever missed by many.

NCAR’s Mesa Lab is literally a science castle dedicated to understanding our planet in an open and collaborative way, and leading the world in that effort. We cannot let this happen.

Trump administration pushes ahead with NOAA climate and weather cuts Despite congressional resistance, agency aims to cut research spending now

My latest: The Trump administration is not waiting for the next fiscal year -- or Congress -- to cut climate science at NOAA. A new document details the money it won't spend *this* year on climate research.

Thanks Mostafa, that's great! I'll keep that one in mind. Am I correct that it has no NIR channel? I'm still searching for a low cost options (if there are any) that have an NIR band.

Does anyone have suggestions for (moderately priced) phenocams with an NIR band that are still being manufactured?

I get the sense that the standard StarDot cameras are no longer being sold, but haven't found an alternative apart from Campbell's CCFC which looks amazing but is def not cheap.

DOE climate report response form We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me. We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

🚨 If you're interested in working on a coordinated response to the DOE climate report, please enter your info on this google form 🚨

Please RT this so as many people see it as possible.

NSF Grant Termination Information Collection Form

Please use this form to submit information identifying specific NSF grants that have been cancelled for any reason after January 20, 2025.


We are tracking these grants to increase transparency, organize affected PIs, and facilitate responses, including via litigation. Please share the form as widely as possible with your networks. 


We are actively building a pipeline to organize these terminations and will soon have a tracker akin to our NIH grant tracker at https://airtable.com/appjhyo9NTvJLocRy/shrNto1NNp9eJlgpA


WE WILL NOT DISCLOSE THE IDENTITY OF ANYONE WHO USES THIS FORM TO PROVIDE INFORMATION. We will keep your identity confidential.


These resources are maintained by Noam Ross of rOpenSci and Scott Delaney of the Harvard T.H. Chan School of Public Health, with input and support from additional volunteers. For any questions, please contact Scott Delaney on Signal (sdelaney.84).


THANK YOU FOR YOUR ASSISTANCE!

🚨Report your NSF grant terminations! 🚨

We are starting to collect information on NSF grant terminations to create a shared resource as we have for NIH. The more information we collect, the more we can organize, advocate, and fight back! Please share widely!

🧪 Tip: You have the right to contest a grant termination, even though NSF says you don't. 🧵

On Friday, NSF terminated 402 grants (per Musk's DOGE).

The notification letters had one of the most egregious violations of fed regulations I've seen so far in these cases:

"not subject to appeal"

Are tropical forests in the Americas changing as adaptation to ongoing climate change? Yes, they are!
Are these changes enough to track their suitable climate?
Not quite! Check out our paper in @science.org www.science.org/doi/10.1126/... to see more of what our network has been working on!
