Warmer Winters Keep Crops Sleepy into Spring, Hurting Yield

by Elise Cutts 21 October 202228 October 2022

Annual crops go dormant during winter. Frosty temperatures cue them to wake up—but the warmer winters brought on by climate change scramble the cold signal, hurting yield.

Mammoths Lost Their Steppe Habitat to Climate Change

by Elise Cutts 19 November 202128 March 2023

Ancient plant and animal DNA buried in Arctic sediments preserve a 50,000-year history of Arctic ecosystems, suggesting that climate change contributed to mammoth extinction.

Summer Could Be Earthquake Season on Mars

by Elise Cutts 1 November 202129 June 2022

InSight data hint that shifting carbon dioxide ice loads, illumination changes, or solar tides could drive an uptick in marsquakes during northern summer—a “marsquake season.”
