Here we synthesize observations of ∼1,900 fluid escape features-pockmarks and active gas flares-across a previously glaciated Arctic margin with ice-sheet thermomechanical and gas hydrate stability zone modelling. Our results indicate that even under conservative estimates of ice thickness with ...
气候变化导致了北极冰盖出现近40年来最严重的融化现象,2022年是北极冰盖流失最严重的一年,有近60万平方公里的冰盖在融化。 In September 2022, the world witnessed a record melting of ice in the Arctic – affecting nearly 592,000 square kilometers of the ice sheet. According to scientists, we looked ...
for example, could see the rainforest system collapse, releasing CO2 into the atmosphere rather than storing it. Or warming Arctic permafrost could cause long-frozen biomass to decompose, releasing vast amount of carbon emissions.举例
How fast is the Antarctic Ice Sheet melting? What is the difference between Antarctic and Antarctica? When did the Antarctic Ice Sheet form? What is the Arctic Ice Shelf? What is sastrugi in Antarctica? Is the West Antarctic Ice Sheet thickening? What is the climate of Antarctica? Is the...
The continental ice sheet is more than two miles high at its center; thus, the air over the Antarctic is far more refrigerated than it is over the Arctic regions. This cold air cascades off the land with such that it makes the nearby seas the stormiest in the world and renders unlivabl...

These two sites—a frozen Arctic lake and a toxic tropical cave—could provide clues to one of the oldest, most compelling mysteries on Earth: Is there life beyond our planet? Life on other worlds, whether in our own solar system or orbiting distant stars, might well have to survive ...
In the month of November, polar bears in their thousands cross the Canadian Arctic, as they head towards the ice sheets of Hudson Bay. The sea ice that forms every winter is the key to the bear's managing to exist, for here they hunt for seals (海豹). ...
The deglaciation of the Late Weichselian Icelandic ice sheet was extremely rapid, and marked by a collapse of its marine-based sections between 15.0 and 14
