The Secrets of Acid Salt Lakes

by Emily Gardner 23 October 202623 October 2026

These stunning bodies of water—saltier than seawater and nearly as acidic as lemon juice—can teach us more about where life can survive, on Earth and beyond.

A Rock Avalanche Buried an Arctic Glacier. Was Climate Change to Blame?

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 21 October 202621 October 2026

Degrading permafrost and earlier small quakes likely weakened a rock slope until it collapsed and buried an Arctic glacier in tons of rock.
