Super Tuesday Lays Out Election’s Environmental Stakes

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 6 March 20246 March 2024

U.S. elections could pull the country back from several environmental tipping points—or push it beyond them. Scientists are urging people to seek climate action beyond the ballot.

How Did We Miss 20% of Greenland’s Ice Loss?

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 8 February 20242 July 2024

The ice loss was hidden in places existing monitoring methods can’t reach, such as hard-to-map fjords. Machine learning helped scientist revise mass loss estimates and uncover patterns in glacial retreat.
