Logged forests may be carbon emitters for years
24 Jan 2023
If you’ve ever been offered the opportunity to donate money to plant a tree to offset a purchase, you’ve probably guessed that trees naturally store carbon.

A climate scientist’s personal reckoning
22 Nov 2022
By Adam Sobel - Bulletin of the Atomic Scientists | A decade ago, Hurricane Sandy changed New York City, forever. New Yorkers now viscerally understand our vulnerability in a way we didn’t before, and the barriers being built to protect us from future storms and sea level rise will reshape the city’s topography. But for me—a scientist who studies hurricanes and climate change, a New Yorker, and a human being—Sandy was a different kind of watershed moment.
