We need to be less hysterical about potential AMOC collapse in 2100 and way more hysterical about the actual mega El Niño in 2027.

When climate scientists say things are going to be horrendous, people find out many years later that we’re right. With this El Niño, the “find out” part will come in months.

I don’t think everyone realizes how bad things are for US science:
For the fiscal year that just ended, the Trump regime withheld $1.4 billion from the National Science Foundation’s research budget, which is about 1/5 of its primary research budget.

Every time I return to Paris, I notice they've done more to reclaim streets from drivers and cars, including removing on-street parking, protecting cyclists from drivers, and prioritizing pedestrians and cyclists in shared spaces. Other cities can learn a lot from Paris.

CRANE, a UK cybersecurity research network, used AI to desk-reject 50% of proposals before human review, including one on the risks of trusting AI models in voice analysis from Lancaster University forensic linguist Claire Hardaker.
This seems like AI doing the right thing in protecting itself. 🙃
This is a joke. It’s horrifying.

The US Senate finds that the fossil fuel industry received $190 billion in tax breaks and subsidies from the Trump regime in exchange for campaign donations. The deregulation and subsidies have increased both energy costs for Americans and the damage from climate change and air and water pollution.

Microsoft significantly reduced its carbon removal purchases by 80% in the first half of 2026. Microsoft bought 93% of all the carbon removal credits globally last year. This is absurd, and no way to determine which method might actually work and scale. Carbon dioxide removal research and development should be government-funded and government-led.
