The explorer led three British expeditions to the Antarctic, and he was in the early stages of a fourth when he died of a heart attack aboard the Quest near the Falkland Islands.

At 80 miles across, Thwaites is the world's widest glacier. It has been nicknamed the "Doomsday Glacier" for the catastrophic effects its thawing could have on global sea-level rise.

West Antarctica is headed for decades of rapid melting no matter how quickly humans cut greenhouse gas emissions, and 2023 shattered records for missing sea ice around the continent.

The man who fell ill is expected to arrive in Australia next week. Until then, he will be cared for in an icebreaker's specially equipped medical facility.

It's the middle of the winter in Antarctica, when the ocean around the continent freezes. But this year there's less sea ice than ever recorded.

Galveston, Texas, has some of the fastest sea level rise in the world. To protect the city, engineers need to know how fast ice in West Antarctica will melt. Scientists are racing to figure it out.

WAMU Visuals Editor Tyrone Turner pairs images to capture the connection he felt to his birthplace — the coastal regions of southeastern Louisiana — while visiting the western coast of Antarctica.

The Earth has already warmed more than 1 degree Celsius. New research suggests that above 1.5 degrees, massive ice melt, ocean current disruptions and coral die-offs are likely.

The collapse, captured by satellite images, occurred in East Antarctica — an area long thought to be stable and not hit much by climate change, scientists say.

An expedition went where few have ever gone to locate the remnants of a ship that became trapped in the ice 106 years ago, dashing the famed explorer's ambitious mission to cross Antarctica.

Arctic communities have long been plagued by soot that drives snow melt and respiratory disease. Now, humans are making their mark in Antarctica.

Ice is usually ephemeral; it doesn't last that long before melting. But some ice on our planet has stayed frozen for millions of years, according to scientists on a quest to find the oldest ice.
