Many governments did this for slavery. But it does have perverse incentives.

There is more to this story too. There were failures of communication, other flawed data which fooled people, and proof (from a submitted abstract) that the NASA team had noticed the hole before the Farman paper.

“DHS is shutting down because it refuses to obey the law” is excellent framing
DHS is shutting down because it refuses to obey the law. They are tear-gassing schools, killing American citizens, and disappearing legal immigrants. Democrats shouldn’t fund an out of control ICE.

Trump’s EPA can’t simply erase climate change — and we’ll all pay the price
On Thursday, the Environmental Protection Agency reversed its “endangerment finding," which found that greenhouse gases are a threat to human health.

Today from my professional society, the @ametsoc.org:

"The repeal of the [EPA] Endangerment Finding does not alter the central unambiguous scientific conclusion: The climate change that people are causing threatens human lives and well-being."

On Thanksgiving, the immigrant children held at the Dilley detention center gathered in the gym for what they thought was a holiday feast.

I've been getting a lot of requests from reporters for comments about the removal of the DOE Climate Working Group report from the EPA's repeal of the endangerment finding.

Here are some comments:
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.
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.

As expected, in the final rule, EPA's Endangerment Finding repeal backs down entirely from challenging the science, choosing to focus on statutory arguments regarding EPA's authority. Good work, everyone who contributed to the @andrewdessler.com review!

They crave status and approval from people they will never get it from, and so they build up shields (literally) to keep them in a bubble they think will keep the exterior world out. It doesn’t work of course.

The House passed a bill this week — the SAVE America Act — that "combines a lot of the worst things that Republicans want to do with regards to voting, and it comes at a time when Trump appears dead set to try to interfere in the midterm elections," says @ariberman.bsky.social from @motherjones.com.

EPA abandoned the DOE CWG report in the Endangerment Finding revocation.

It makes sense, though. It would have been destroyed in court. They violated so many rules in the production of that report.

Also, the May draft was never publicly released, so that’s also a big problem.
From FN 8. "...in light of concerns raised by some commenters about the draft report authored by the U.S. Department of Energy’s Climate Working Group (CWG), the EPA is not relying on the May 27, 2025 CWG draft report"
CBP didn’t give her or anyone any water; she asked 3 times accg to other reports. CBP killed a 7yr old.

Does anyone have a link to the actual final rule from EPA? I don’t see it somewhere obvious on the EPA site.
As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org
There is No Scientific Justification to Revoke the Endangerment Finding
The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.
