Glaciers are melting in many places on Earth today. But glacier loss in the Peruvian Andes is happening particularly rapidly. New research reports a reduction of almost 30% between 2000 and 2016.

A new study suggests that about 4,000 years ago, a combination of isolation, extreme weather, and the arrival of humans on Wrangel Island in the Arctic Ocean killed off Earth’s last population of mammoths.

A new study that analyzed rock from deep within the Chicxulub impact crater helps reveal what happened within the first 24 hours after the asteroid impact that doomed the dinosaurs.

Carbon dioxide, CO2, makes up less than one-twentieth of 1% of Earth’s atmosphere. How does this relatively scarce gas control Earth’s thermostat?
