Rise in sea level due to possible collapse of West Antarctic Ice Sheet may have been underestimated
Highlights
Researchers always found this extra one metre of global sea-level rise
Gobal sea levels could rise by about 3.2 metres (over 10 feet)
While the world s attention has been focussed on taking control of the novel coronavirus pandemic, a new study by researchers at Harvard University has found that seawater levels are rising faster due to climate change than they were thought to be earlier. The rise in the global sea level due to the possible collapse of the West Antarctic Ice Sheet may have been underestimated on a significant level, says the study published in Science Advances. As p ....

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. ....

Sea Level Rise From Antarctica Could Be 30% Higher Than Thought: Study

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 the West Antarctic ice sheet were to collapse, the sea levels would increase by about 10 feet. ....

It’s also a defining timeline of an astonishing ice mass loss rate of 500% more than the last decade of the previous century. Throughout human history, this has never happened with such far-reaching extent so rapidly.
The proof is found in the numbers. For example, Greenland and Antarctica combined ice mass loss is truly an eye-opener: “The assessment is supported by NASA and the European Space Agency… The team calculated that the two ice sheets together lost 81 billion tons per year in the 1990s compared with 475 billion tons of ice per year in the 2010s a sixfold increase.” (Source: Greenland, Antarctica Melting Six Times Faster Than in the 1990s, Global Climate Change, NASA, March 16, 2020) ....
