Nature Report, Killed by Trump, Is Released Independently

Scientists and other experts were preparing an assessment of the health of nature in the US when Trump returned to the White House. He canceled the report. The researchers went ahead and compiled it on their own. This week, they released a 868-p draft for public comment and scientific review.

They were going to pass rules to phase out gas stoves, until they received 20,000 public comments against the regulations. Except, oops, it turns out the comments were generated by AI.

Good news: Scientists were wrong about how bad sea level rise is.

Bad news: It’s even worse than we thought.

It’s not just you. They have been having these glitches. I have emailed them myself. They said that if anybody’s having an issue, send them an email and they will go in and fix each account.

Operation Epic Fury Making Sense of the Energy Risks and beyond

A useful piece that underscores the benefit of energy sources that do not have to pass thru the Strait of Hormuz (e.g. sunshine & wind). Renewable energy is an investment in geopolitical resilience.

In 1938, the German Reich invalidated all German Jewish passports.

They must surrender them, after which their ID will mark them as a Jew.

In 2026, the state of Kansas invalidated all correct trans drivers licenses.

They must surrender them, after which their ID will mark them as trans.

Check out the last 100 years of January sea surface temperature departures in the new ERSSTv6 dataset (up through 2026). 🌊

Learn more about this upgrade in doi.org/10.1175/JCLI... and doi.org/10.1175/JCLI.... If the data latency is similar, I will be using this in replace of my v5 graphics.

Breaking News!
Code Gobsmacking Bananas!!!

As of Feb. 21, 2026, global sea-surface temperatures are above 21.0Β°C (at 21.02Β°C), the second hottest on record for the date.

With a looming El Nino ahead later this year, global SSTs are likely heading towards a new record maximum.

This is a victory for academic freedom and education equity.

Update: Young people represented by @youthvgov.bsky.social have also filed a petition challenging the rule.

They kids β€” who successfully sued Montana over its rules enabling climate change, and settled with Hawaii later β€” claim the rule violates the U.S. Constitution.

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.
"Uncertainty carries a positive cost."

Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate changeβ€”all so the fossil fuel industry can make even more money.

January 2026 was the fifth-warmest January on record globally. Europe saw its coldest January since 2010, while much of the Arctic was unusually warm. Arctic sea ice extent was third-lowest on record for the month.

While independent bookstores are giving out free whistles, hosting protest sign making events, and donating proceeds to mutual aid, Amazon is *checks notes* providing technology that assists ICE in their terrorizing of communities.
