#Melissa rocketed to Category 4 strength overnight — gaining 70 mph in just 24 hours over unusually warm Caribbean waters made 600–700x more likely by climate change.
It’s the 4th storm this season to undergo Extreme Rapid Intensification. (#Erin, #Gabrielle, #Humberto)

As Hurricane #Melissa approaches Jamaica, we look back to a similar event in August 1903.
The rainfall from that storm would have been more intense in today’s warmer climate.
#Melissa will likely drop more rain now than it would have done a century ago.

Global sea surface temperatures are now the coolest since May '23 as we transition into the flipside of El Nino (La Nina). It's the steady, long-term warming we should be focused on. It will continue until we bring carbon emissions to zero.

Hurricane Melissa could be one of the most worst hurricanes on record for Jamaica...and it's a textbook example of how climate change is making hurricanes more dangerous: explosive intensification, slow movement, and massive rainfall.
If you know any there, please make sure they’re prepared 🙏

When climate deniers argue that atmospheric CO₂ was higher in the past, it's idiotic.
Humans evolved to live in the current climate, and we built our society and infrastructure accordingly.
The atmosphere didn't have oxygen billions of years ago, and we certainly don't want to return to that.

Earth's atmosphere hasn't had this much CO2 in millions of years
New data shows that CO2 levels have broken through 430 parts per million, an indication that human-caused global warming will continue to warp the environment.

The new WMO State of the Climate report has a section by Gavin Schmidt and me on attributing exceptional 2023 and 2024 warmth.
We find that while 2024 can be well explained by changes in forcings and internal variability, 2023 remains more of a mystery:
