A team of scientists are sailing to "the place in the world that's the hardest to get to" so they can better figure out how much and how fast seas will rise because of global warming eating away at Antarctica's ice. Thirty-two scientists on 6 January 2022 are starting a more than two-month mission aboard an American research ship to investigate the crucial area where the massive but melting Thwaites glacier faces the Amundsen Sea and may eventually lose large amounts of ice because of warm water. The Florida-sized glacier has gotten the nickname the "doomsday glacier" because of how much ice it has and how much seas could rise if it all melts - more than two feet (65 centimeters) over hundreds of years. Because of its importance, the United States and the United Kingdom are in the midst of a joint $50 million mission to study Thwaites, the widest glacier in the world by land and sea.
