For my latest @nature.com piece, I spoke to 19 different scientists across EPA, NOAA, NIH, NASA, and USGS to document how science is being dismantled across US federal agencies.
According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

📈 Up to 10% wetter (💧+14 mm/day)
💨 Up to 10% windier (+8 km/h)
Our new @climameter.bsky.social study shows that natural variability alone can’t explain these changes — human-caused warming is a key driver.

STRENGTH: Warmer water is hurricane food
RAINFALL: Warm air holds more water vapor
SURGE: Warmer water expands, warmer ice melts, sea levels rise
PREDICTION: hotter seas mean faster intensification
