Antarctica is melting faster than ever. Here’s what we can do about it
2023年11月15日 · The shape of the land under the ice affects its vulnerability. The West Antarctic Ice Sheet, which could raise global sea level by over three metres, depends on the Thwaites Glacier’s stability. This part of the ice sheet rests on a downward-sloping submarine bed, making it prone to irreversible retreat.

2020年1月23日 · Since the 1970s, we have lost 75% of the volume of Arctic summer sea ice. The Arctic affects the jet stream, causing extreme weather all over the world. The Arctic used to be white but now it's turning blue, and absorbing more heat in a feedback loop.
Antarctica's ice caps melting faster than previous estimates
2018年6月14日 · Jahda Swanborough, Lead, Environmental Initiatives at the World Economic Forum, said: "News that the world’s largest ice sheet is melting more rapidly is a loud wake-up call. This is a classic example of a global commons challenge – the consequences of Antarctic ice caps melting have the potential to affect most people on the planet.
The Antarctic ice sheet is melting. And this is bad news for humanity
2023年3月3日 · The Antarctic ice sheet has been strongly decreasing since 2016. If left unchecked, the complete melting of the West Antarctic ice sheet would cause a global sea level increase of 3.3 metres in the future, says an expert. At present, the world is heading towards a warming of 2.8C by the end of this century.
What happens if ice in Antarctica continues to melt ... - World ...
2021年10月7日 · Research has identified so-called “basal melt” as the most significant driver of Antarctic ice loss. Basal melt refers to the melting of ice shelves from underneath, and in the case of Antarctica, interactions with the ocean are thought to be the main cause. But gathering scientific observations beneath ice shelves is a major logistical ...

2021年5月4日 · The study finds that, between 2000 and 2019, mass loss from glaciers was 47% higher than from the Greenland ice sheet (GIS) and more than twice that of the Antarctic ice sheet (AIS) The authors also note that, while glacier mass loss “distinctly accelerated” over the entire 2000-19 period, the mass loss from ice sheets decelerated since a ...
35 years of arctic ice melting, in 125 seconds - The World …
2019年11月18日 · A pattern similar to the Arctic ice melting is seen in the Antarctic, which has lost around a sixth of its ice cover since 2014. The region has lost as much sea ice in the past four years as the Arctic lost in the past 34 years.
Climate change: How quickly are ice sheets melting on Earth?
2021年1月29日 · “Although every region we studied lost ice, losses from the Antarctic and Greenland ice sheets have accelerated the most,” lead author Dr. Thomas Slater said in a statement for the University of Leeds. “The ice sheets are now following the worst-case climate warming scenarios set out by the Intergovernmental Panel on Climate Change.

2020年8月20日 · Antarctic sea ice is a habitat for wildlife. Image: REUTERS/Alexandre Meneghini Methane trapped in polar ice In the Arctic, NASA highlighted the future climate warming potential of methane in melting permafrost.
How vulnerable are the world's ice sheets to climate change?
2022年8月16日 · The East Antarctic Ice Sheet is highly sensitive to relatively modest temperature increases, even if it is currently stable. Its fate will depend on how effectively we can manage global warming. The eastern two thirds of Antarctica is covered by an ice sheet so large that if it melted the sea would rise by 52 metres.
