New analysis of Antarctica's melting glaciers refines our understanding of climate change, while risks of global impacts remain significant.
"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."
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 ...
This reflectivity, or 'albedo', means that the ice warms much less quickly than surfaces not covered by ice. If the ice begins to melt, the albedo drops, creating a negative-feedback loop as the surface absorbs more heat, causing more melting, causing the...
Outline how the 2024 melt season in Antarctica compares with previous years. Refer to graph and map data in your answer Examine how the mass balance of ice sheets has been altered by snow accumulation in the upper regions and increased melting of the ice in lower regions ...
Now, scientists have found that the East Antarctic Ice Sheet (EAIS)—considered largely unaffected by climate change—may also be melting at an unexpectedly rapid speed. The WAIS, whose base is below sea level, has long been considered the most likely to break down. Besides gravity, a deep ...

“If the surface of the ice sheet is melting it can form meltwater lakes that rainfall can add to. Meltwater lakes tend to be blue rather than white, making them darker than the ice underneath and therefore they absorb more sunlight, which makes them warmer.” This can create ...
