Debating the aesthetics of #wind & #solar is a luxury. The real crisis is climate change—threatening billions with deadly heat & catastrophic ecosystem breakdowns ♨️🥵🔥 Green #energy is a necessity🍃 Challenges exist (noise, land use) but are manageable - biggest risk is inaction #dkpol #climatechange

Stanford University’s student-run newspaper sued two senior Trump administration officials Wednesday, challenging Secretary of State Marco Rubio’s ability to revoke student visas and deem an individual deportable based on the content of their speech.

HUGE: The Trump administration will no longer permit any solar or wind projects on federal lands unless they produce more energy-per-acre than coal, gas or nuclear power plants.

Solar and wind literally produce less energy per acre, so simply this may just kill off any project on federal lands.

Spot on, as usual, from @doctorvive.bsky.social...

"We need to correct a false narrative that the #climate threat is under control. These enormous risks are potentially catastrophic. They would undo the connections between human & ecological systems that form the basis of all of our civilisation"

Scientists have been publishing climate models since ~1970.

A good way to evaluate their skill is to compare what they expected to happen in the years after the model was published to observed climate changes.

It turns out most models were pretty spot-on:

"For me, the answer now lies in refusal, the withdrawal of participation from systems that require dishonesty as the price of belonging."

Today I am resigning from the National Science Board and the Library of Congress Scholars Council.

I wrote about my decision in TIME.

A victory for the federal scientific workforce! We could not stand by while this irreparable harm continues at NSF, NOAA and all our scientific agencies.

TODAY the judge granted our request to temporarily HALT the mass firings at federal agencies under Trump’s Executive Order.

He wore the cheesehead hat in WI. Spent $20 million. Paid people to sign petitions. Paid people to canvas. Did million dollar giveaways. A rally. TV interviews. But I guess people in Wisconsin didn’t appreciate an oligarch trying to buy their civil liberties.

1. One of capitalism’s greatest successes is to shut down our imaginations. With the help of its favoured tools - neoliberalism and fascism - it persuades us that “there is no alternative”. Our first task is to re-ignite our moral imaginations and name our alternatives. 🧵

Today, a broad coalition of scientific professional societies who represent over 92,000 scientists are speaking out against the politicization and demonization of Federally funded science and government scientist jobs.

It was an honor to help the Union of Concerned Scientists with this! 🧪🌎

Thinking about the good people of @noaa and @nws today. Such a dark day for our nation and our safety.
