The poles may be warming faster than anywhere else on Earth. A new study explores the consequences for these icy regions—and for the rest of the world.

A powerful winter storm swept over the German RV Polarstern icebreaker recently, tearing new cracks in the ice floe next to the ship, sending ice-based instruments adrift and forcing a rescue-and-reconstruction process that could take weeks of work by ���Ҵ�ý�ƽ������ and other scientists.

Nearly 100 scientists and staff from around the world, including CIRES scientist Ted Scambos, departed recently to conduct fieldwork in one of the most remote and inhospitable areas on Earth: Thwaites Glacier in West Antarctica.

Mongolia's Tsaatan reindeer herders depend on munkh mus, or eternal ice, for their livelihoods. Now, soaring global temperatures may be threatening that existence.
