A big part of the authoritarian playbook is war. War takes over the news. War blots out criticism. War divides a nation’s people, subjecting those against it to being called unpatriotic. War grants leaders all sorts of emergency powers. War consumes everything else.

We mustn’t let this war do so.

Sigh.

This is the directorate that funds all of the earth, ocean & atmosphere research at NSF.

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. πŸ§΅πŸ‘‡

Besieged Berkshire Utility Tries to Rewrite Who Pays for Wildfires Utility-ignited fires have become a thorny issue for Warren Buffett’s successor.

This much is clear: As climate change has made wildfires more frequent and destructive, the issue of who pays for their costs has come to a head.

NSF officials break silence on how AI and quantum now drive agency grantmaking Leaders acknowledge White House role in controversial moves

The National Science Foundation is systematically being converted to the National AI and Quantum Research Foundation.

β€œI see it as the administration exerting political control over what has traditionally been NSF’s ability to fund the best science.”

Sam Alito has an oil money problem 30 percent of Alito’s individual stock portfolio is directly tied to fossil fuels.

The Supreme Court has decided to hear a major climate case against fossil fuel companies

Alito has not recused himself, despite owning nearly $200,000 in fossil fuel stocksβ€”including in Phillips 66 and ConocoPhillips, which are being sued in cases that would be directly affected by a SCOTUS ruling

This is a valid point. I think we can be frustrated by all of the above…

Shows pretty clearly the decline in climate change coverage by the NYT and WaPo since 2020; LA Times and USA Today hold pretty steady and the Wall Street Journal just doesn’t cover this topic, why am I not shocked.

The biggest barriers to solving the climate crisis are political, not technological. We don't need an AI to help us because we already know what we need to do. We just lack the political will to do it.

(And one of those things we need to do is turn off AI data centers that run on fossil fuels.)

I think this sport was inspired by what parents do to teach their kids how to ski: definitely hike up/ down some hills with skis on, then run up a flight of stairs or two, there might be a fun ski jump in there, wearing a backpack full of kids snacks. All while lugging a kiddo on skis 🎿

It is shocking how quickly one of the biggest benefits of U.S. higher education, the ability to recruit the best students from around the world, is eroding.

As part of some research I’m doing, I’ve been reading the background on resistance to regulation of pesticides in the 1950s-1970s. The reason that people justified not banning chemicals that we knew caused human and environmental harm was also β€œfood security”.

The timeline we are on is a circle.

NSF still doesn't have a director or deputy director. We have no idea who's actually running them. Board members have resigned over this and over the political control of the agency by 20-something political hacks.

Yet people persist in acting like everything is normal.

The US administration has revoked the EPA’s 2009 Endangerment Finding - the foundation for federal climate regulation.

This decision comes despite the overwhelming evidence of the economic, climate and public health harms of pollution. CCAG experts Alice Hill and Tessa Hill share their thoughts.

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.

The American Academy of Actuaries warns that dismantling NCAR would degrade the catastrophe models insurers depend on to price climate riskβ€”driving up premiums and threatening coverage availability nationwide.

I really do hate that people who are geological illiterate keep pointing to records compiled by paleoclimatologists to downplay climate change because, if anything, the lessons of deep time only emphasize how extraordinary and unprecedented the rate of modern warming is.

What the National Center for Atmospheric Research means to the atmospheric sciences Born out of a time of great need for the federal government, NCAR plays a role with few analogues.

Great piece out today in Physics Today on historical origins, contemporary relevance, & fundamental irreplaceability of the National Center for Atmospheric Research, which remains at imminent risk of dismantling for partisan political reasons.
