Teams of scientists sailing to Antarctica's Thwaites Glacier, nicknamed the Doomsday Glacier, are having trouble getting there.
This photo provided by environmental scientist David Holland shows tents set up on the Dotson Ice Shelf in Antarctica on Monday, Jan. 31, 2022. A large iceberg broke off the deteriorating Thwaites glacier and along with sea ice it is blocking two research ships with dozens of scientists from examining how fast its crucial ice shelf is falling apart. The smaller Dotson ice shelf is about 87 miles west of the Thwaites ice shelf.
Plans to examine the glacier's crucial ice shelf haven't been stopped but are sidetracked a bit, officials said. The ice shelf “is the most important part of Thwaites and it’s protecting itself and hiding from us,” Holland said in a first video interview from the Dotson ice shelf. He called Dotson’s ice shelf “this beautiful white desert-like landscape, brilliantly white actually. And it will all be gone and replaced by the Pacific Ocean in due course.”
While parts of Thwaites’ edges have fast-spreading cracks like a car windshield, safety mountaineers inspected where researchers set up camp on Dotson, and Holland isn’t worried much about danger. As he spoke, a red helicopter landed to evacuate one of his eight-member team the ship because of a sprained ankle, which Holland said isn’t too serious.
If all of Thwaites collapses, it could raise seas around the globe more than two feet but that could take hundreds of years, scientists say.While places like Greenland — where in 2019 Holland studied the melting Helheim Glacier — are melting from warm air above, Thwaites and its neighboring glaciers have it worse because they are melting from the warm water below the ice, which acts faster, Holland said.

Giant iceberg blocks scientists' study of 'Doomsday Glacier'A large iceberg broke off the deteriorating Thwaites glacier and, along with sea ice, it is blocking two research ships with dozens of scientists from examining how fast its crucial ice shelf is falling apart. Plans to examine the glacier's crucial ice shelf haven't been stopped but are sidetracked a bit, officials said. This was the last of three international scientific expeditions aimed at the vulnerable ice shelf, said British Antarctic Survey geophysicist Rob Larter, chief scientist of the first research mission.
