Scientists came to Greenland on an unprecedented mission to drill for rocks that would reveal the fate of the country’s fast-melting ice sheet. A sudden crack in the ice threatened their experiment.

By studying coral fossils on the Seychelles islands, researchers have revealed where the deluge will hit hardest when sea levels rise.

Coral reefs in the Seychelles off Africa may indicate where sea level rise will be felt the hardest as human-caused climate change impacts the world’s oceans.

I went with scientists to study a remote part of the Greenland ice sheet. Here’s what I learned, and why it matters for the rest of the world.

Climate reporter Sarah Kaplan reports from the Greenland Ice Sheet where researchers drill deep into the ice with hopes to better understand climate change.

• Climate

Scientists journeyed to Greenland in an unprecedented experiment to drill for rocks beneath the ice sheet. But a crack in the ice threatened their mission — and their ability to predict the fate of the warming world.

• Environment

A new analysis suggests climate change could shut down the circulation of Atlantic Ocean currents by 2050. But outside researchers say more data is needed.

• Environment

Long-lost samples of twigs and rocks show that Greenland once lost a tremendous amount of ice under climate conditions very much like the ones humans have created and are currently living in — implying coasts could soon be submerged under several feet of sea level rise.
