🌪️ Happy to share this new paper from @mktippett.bsky.social and I. We constructed a synthetic event set for U.S. tornado outbreaks. It has 200,000+++ events, which can be boiled down to resolve localized risk, and we detect robust shifts in activity due to ENSO and trends. doi.org/10.5194/nhes...

I usually include NOAA NCEI billion-dollar weather/climate disaster figures in my talks. Over the last couple months, I've spent extra time highlighting who makes them and why it's so valuable, including "while we still have this data..." to convey my worry. Sadly I guess my fears were warranted.

BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency. Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

Almost all NOAA Research websites that rely on cloud services - including Amazon, Google and WordPress - are poised to disappear at midnight ET Saturday after a contract was targeted for "early termination." Labs may also feel the effects. Story for @bloomberg.com (free link):

Scoop(let): NOAA is folding the Climate Prediction Center in with the Weather Prediction Center, partly so CPC doesn't stand out so much with the word "climate." (CPC does not study/predict climate change so much as El Niño/La Niña, seasonal climate.) www.axios.com/2025/03/27/n...

NOAA merges Climate Prediction Center with another unit, reflecting climate anxiety

The move reflects concerns over the Trump administration's sensitivity to CPC's title.
