Illegal miners have forced Peru’s oldest environmental research station to suspend work Staff at the Panguana biological research station have received death threats

My latest for @science.org. - Illegal miners have forced Peru’s oldest environmental research station to suspend work.
Gold mining has so far led to the deforestation of 140,000 ha of Amazonian rainforest in Peru - about half the size of Yosemite National Park

Trump's Climate Supercomputer Plans Threaten US Insurance Market: Actuaries A new letter from the American Academy of Actuaries draws a direct line between the planned dismantling of NCAR and higher homeowners insurance costs for US consumers.

Need more industries to speak up against the attacks on NCAR.

It is hard to watch NSF bow so easily to their destroyers.

Vannevar Bush formed the NSF out of the US response to the fascists in WWII.

We knew the NSF letter about NCAR would come. I think this is an occasion that will require great coordination and strategical thinking. UCAR should respond as a block, coordinating a response across universities (especially in the South, and large public universities that use NCAR data a lot)

I would strongly encourage those who value the scientific & societal legacies of NCAR to offer feedback by March 13. I would expect, under present circumstances, perspectives from industry partners will be especially critical, though everyone's voice is of course important.

The federal govt may be burning global cooperation on climate science to the ground, but we can and are pushing back where we can. We have more than 70 US scientists currently on IPCC reports, with more to be selected this month for CDR methods report. The USAA-IPCC coalition is up for this fight.

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 moves to dismantle major US climate research center in Colorado The Trump administration is breaking up the National Center for Atmospheric Research, taking aim at one of the world's leading climate research labs.

The beautiful idea of NCAR, to improve understanding of our planet through a cooperative, shared and open intellectual team effort, is literally what has got me out of bed every morning for nearly two decades. This cannot, CANNOT be allowed to happen.

A deeply dangerous — and blatantly retaliatory action against Colorado — by the Trump administration.

NCAR is one of the most renowned scientific facilities in the WORLD — where scientists perform cutting-edge research everyday.

We will fight this reckless directive with every legal tool we have.

This 15-story data tower in the heart of the Amazon collects vital climate data that is shared with Americans in California and across the country.

The Trump Administration can ignore reality and worsen the climate crisis, but California will never stop fighting for our future.

We just published the Global Carbon Budget 2025, with a mix of bad news (CO2 emissions continue to grow) and encouraging news (35 countries saw emissions decline over the past decade while growing their economies).

MAJOR NEWS: @GavinNewsom signed SB 79, my bill allowing more housing near public transit — rail, subway, rapid bus.

It’s a huge step for housing in California. It’ll create more homes, strengthen our transit systems & reduce traffic & carbon emissions.

Thank you, Governor!
