New analysis of Antarctica's melting glaciers refines our understanding of climate change, while risks of global impacts remain significant.
Geoscientists led by the University of Leicester and the University of Southampton have discovered periods of sudden melting in the Antarctic ice sheet in a new climate record from over 20 million years ago. The research, recently published inNature Communications, reveals how sensitive our planet’s...
Antarctica's(南极洲) melting ice, which has caused global sea levels to rise by at least 13. 8 millimeters over thepast 40 years, was thought to primarily come from the unstable West Antarctic Ice Sheet (WAIS). Now, scientists havefound that the East Antarctic Ice Sheet (EAIS)-considered...

Ice-sheet collapseLithosphere thicknessMelt lubrication2022 The AuthorAntarctica is losing ice mass by basal melting associated with processes in deep Earth and reflected in geothermal heat flux. The latter is poorly known and existing models based on disputed assumptions are controversial. Here I ...
"The problem is that the melting ice and rising sea tends to follow an exponential path," said Englander. "That would change or evensubmerge many coastal cities. The effect would also go through marshlands and far up tidal rivers."
We calculate the present ice budget for Antarctica from measurements of accumulation minus iceberg calving, run-off and in situ melting beneath the floating ice shelves. The resulting negative mass balance of 469 Gt yearu22121 differs substantially from other recent estimates but some components are ...
Some scientists warn that ice near the Earth’s Poles may indeed be melting. This “polar meltdown” may be the first sign that the Earth is heating up. We could be in very serious trouble if this trend continues. It is estimated that a meltdown of as little as 10 percent of Antarct...
The massive iceberg that broke off the Larsen C Ice Shelf may be a harbinger of a continent-wide collapse that would swamp coastal cities around the world.
