Since 1993, melting land ice has contributed to at least half of global sea level rise and scientists have previously warned that the vast ice sheets of Antarctica were disappearing faster than worst-case scenarios.
Adam Jenkins, National Science Foundation/Via International Thwaites Glacier Collaboration Scientists say if the West Antarctica Ice sheet were to collapse, global sea levels could rise by about 10 feet. But a new study says that this figure could be about 3.3 feet higher. That is because as the glaciers melt, the bedrock under the ice sheet could rise out of the ocean. The global sea-level rise due to the melting of Antarctic ice sheets in the next 1,000 years could have been underestimated by about 30%, a new study says. Previous studies had estimated that if t...
Oslo [Norway], April 30 (ANI): Melting of the Arctic ice sheets caused rapid methane release from the ocean floor during the last two deglaciations, according to a new study led by scientists at The University of Tromso - The Arctic University of Norway.

A study published on Monday in Proceedings of the National Academy of Scientists says that plant fossils found in a sample of dirt collected from a mile beneath the ice in the mid-1960s suggest that the world’s pre-human climate was at one point warm enough to completely melt the Greenland ice sheet.

NASA time lapse photos show Alaska, Antarctica, Greenland glaciers in rapid irreversible melt Updated Jan 06, 2021 | 15:23 IST NASA satellites have provided more than 40 years of Earth observations from space – a critical, global record that has already proved crucial in helping scientists better understand our dynamic, fragile planet. Alaskan glacier time lapse photo Climate change can be compared to the dacoit that has stepped right in through your house's doors while you kep insisting that it is an illusion or gimmickry. It's real, it's hazardous to our existe...
