Our climate reporter Raymond Zhong describes America’s shifting relationship with polar research amid the threat of rising sea levels.

None of the main research on the voyage of the Araon was funded by the U.S. National Science Foundation, a sign of the difficult times for American science.

Scientists on the Thwaites Glacier attempted to install equipment beneath the ice to better understand how it is melting. Our climate reporter Raymond Zhong walks us through their landmark experime...

The fastest way into the gaps between gigantic blocks of a broken-up glacier is by lowering instruments from above, through the door of a helicopter.

After working and camping for a week on Thwaites Glacier, scientists were ready to start drilling into the ice, if only the weather would let them.

Scientists are using radar to study damaged ice both in Antarctica and, with the help of a NASA spacecraft, on Jupiter’s ocean moon of Europa.

In the unforgiving polar wilderness, scientists go to great lengths to safeguard the devices that gather precious data.

Low clouds have lifted long enough for helicopters to ferry scientists and their gear to a fast-melting glacier on the edge of Antarctica.

Generations of Times journalists have journeyed there with scientists. Their coverage traces humankind’s changing relationship with the most mysterious continent.

Bad weather has postponed attempts to set up camp on the Thwaites Glacier. So researchers got onto the sea ice and met a local.

The clock is ticking. But low clouds have prevented helicopters from moving scientists and gear onto the continent’s fastest-melting glacier.

The clocks aboard our icebreaker will be changed several times en route to Antarctica. It’s one of many things that make the expedition feel otherworldly.
