The Nov-Apr 2025-26 was the warmest Nov-Apr on record (since 1895-96). A very large portion of the western U.S. had their single warmest Nov-Apr compared to all other Nov-Apr periods. 🔥🔥🔥

Words fail. To my knowledge, an all-out purge like this is unprecedented in the 76-year history of the US National Science Board. Unclear what this means for the National Science Foundation and its purview (which includes the National Center for Atmospheric Research), but I'm feeling queasy.

To help illustrate how large an area is covered by record breaking temps, @cyclonicwx has a great graphic for this. Anything red or deeper is record territory. Huge area.

Denmark's coal-to-wind transition is one of the most dramatic energy transformations of the past three decades. In 1990, coal provided 90% of Danish electricity. Today it is under 3%. Wind now covers roughly 60% of electricity generation. The last coal plant is scheduled to close by 2028.

In my latest installment in an ongoing series on climate change and hurricanes, I look at how strong a hurricane can get. In the Persian Gulf, where SSTs get to 95°F, a 300 mph hurricane is possible. yaleclimateconnections.org/2026/04/how-...

It’s Earth Day 🌎 If we are being realistic and honest - which really is the least we can do - it’s very likely warmer today than anytime in the last 120,000 years. And, the global warming rate the past century - and especially the last 30 years - is “exponentially”… 1/

"The Climate Scientist Who Fought Back" | My interview with the legendary @dfenton.bsky.social for the new #FentonForecast podcast: www.fentonforecast.com/episodes/epi...

Aside from Florida, nearly the entire contiguous U.S. has experienced earlier than average first plant blooms in 2026. Earlier springs can cause longer allergy seasons, accelerate wildfire risk, increase pests/mosquitoes, and lead to less reliable snow-fed water. Map: www.usanpn.org/data/maps/sp...

🔥 High Fire Danger today and tomorrow in North & Central Florida. So far it’s the worst fire season in at least a decade, with 2.5X the average acreage burned and 1800 individual fires. With humidity as low as 25% and winds gusts 💨 to 30 mph, any sparks will ignite and spread fire rapidly… 1/

A new language for climate change was voted in: “kokushobi” heat, >40°C (104°F), from the Japanese word koku, meaning harsh or cruel. 2nd choice for the new heat term was ‘super-extremely hot day’ or ‘cho-mosho-bi’, while ‘sauna day’, ‘stay-at-home day’ and ‘boiling day’ were also among the choices.
