Important piece covering the ways in which warm ocean waters--made more likely by human activity--contributed to the catastrophic impacts we're seeing from #Melissa.
"Hurricane Melissa has been astonishing to watch — even as someone who studies how these storms are impacted by a warming climate," @andrajgarner.bsky.social told @zeitlin.bsky.social.
Here's more on the storm that is battering Jamaica — and astounding researchers:

You can spend your career doing work that shows we should expect more dangerous storms in a warmer climate... But it never gets less mind-blowing or heartbreaking to watch something like this unfold.

The human and social impacts of #Melissa are almost certain to be beyond devastating.
The western end of Jamaica where #Melissa is projected to make landfall has the least well-built structures of anyplace on the island. Graphic is from a 2021 paper, "Poverty and hurricane risk exposure in Jamaica": www.researchgate.net/publication/...

For only the second time in recorded history, an Atlantic season has produced three Category 5 hurricanes... the previous year was 2005. This puts 2025 in an elite class of hurricane seasons. It also means that nearly 7% of all known Category 5 hurricanes have occurred just in this year.

Changes we expect to hurricanes in a warmer climate include more rapid strengthening, slower forward movement, and more torrential rainfall--all characteristics that describe the incredibly dangerous #Melissa. If you know anyone in Jamaica, please make sure they get to safety.
