As early as 1975 Kennett and Shackleton27identified low δ18O in planktonic foraminifera in the Gulf of Mexico as indicators of deglacial freshwater input from the melting Laurentide Ice Sheet. With the same method, a major freshwater event associated with the Younger Dryas in front of the Macken...
Massive ice sheet in Arctic is melting fastdoi:10.1016/s0262-4079(19)32406-6Michael Marshall
Melting ice in Antarctica could trigger volcanic eruptions beneath the continent’s vast ice sheet, creating a slow but dangerous feedback loop, scientists warn. https://t.co/IelD4LE5qI— Svein Tveitdal (@tveitdal) January 7, 2025 Because the Sea-Ice Extent decreases both at the Arctic an...
How fast is the Antarctic Ice Sheet melting? How many glaciers were there in 1950? How many glaciers does Alaska have? How cold is the Antarctic Peninsula? How thick is Thwaites Glacier? How is Arctic Sea ice different from glaciers and icebergs?
(重新冻结) its ice — Arctic is the northernmost region of Earth and it is extremely cold, but global warming is melting (融化) its ice. Over the past 30 years, the oldest and thickest parts have reduced in size by as much as 9% — Arctic ice melting is worrying because it makes ...

ice retreat. This intensified decline of early-summer sea ice accelerated the melting of sea ice throughout the summertime by lowering regional albedos. Our findings highlight the important impact of the larger heat discharge of pan-Arctic rivers, which can reinforce Arctic sea-ice loss in the ...
