Warm Autumn Winds Could Strain Antarctica’s Larsen C Ice Shelf

New research shows that the Larsen C ice shelf—the fourth largest ice shelf in Antarctica—experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017.

Carbon Lurking in Deep Ocean Threw Ancient Climate Switch, Say Researchers

A million years ago, a longtime pattern of alternating glaciations and warm periods dramatically changed, when ice ages suddenly became longer and more intense. Scientists have long suspected that this was connected to the slowdown of a key Atlantic Ocean current system that today once again is slowing. A new study of sediments from the Atlantic bottom directly links this slowdown with a massive buildup of carbon dragged from the air into the abyss.

Deep-Sea Drillers Investigate Shedding of Antarctic Icebergs

Scientists are sailing to remote areas of the Southern Ocean to drill cores from the bottom that they hope will contain clues to past rapid changes in the Antarctic ice, and how it may react to warming climate today.

Shade-Grown Coffee Helps Ecosystems and Farmers

A new study finds that coffee farmers could be better off financially if they used shade-growing practices for part of their production.

Drill Cores From Pre-Ancient Greece Open Insights to Climate

Newly analyzed drill cores taken from the bottom of Greece’s Gulf of Corinth show that sediment flow into the basin has varied dramatically over the past 500,000-plus years, as the earth passed in and out of ice ages, and humans later dominated the surrounding landscape.
