Hurricane Patricia drew immediate attention by intensifying from a tropical storm to a Category 5 hurricane in a single day. It soon developed the fastest winds ever recorded in a western hemisphere storm. Meteorologists and climate scientists have already begun their scientific investigations of how a cyclical El Niño and […]

The Faucet
The effects of climate change on individual extreme events consist of thermodynamic changes and atmospheric circulation changes.

I recently discovered this video—”What you need to know about climate change in 24 easy steps”—by Dr. Joe Hanson, a popular #SciComm writer and the creator-host of ‘It’s Okay To Be Smart‘ on PBS. I circulated a number of his steps on CCNF’s internal platform and received the following responses from Drs. Will Howard and Scott Denning, which I […]
