Ancient Antarctic ice sheet collapse would cause a global flood

As climate change continue to increase, new research brought forward by geologists suspect that the West Antarctic ice sheet (WAIS) could melt and cause a massive worldwide flood.

The study, which was presented at the American Geophysical Union earlier this month, highlights the concerns and the risks if the sheet ─ originally disappeared 125,000 years ago as a result of a changing climate to collapse.

“Ice-sheet models link Pine Island glacier, the absence of full WAIS collapse in ice sheets on the mountains,” the study abstract reads. “Our record thus provides the first direct indication of a much smaller LIE WAIS, providing paleo-context for the sensitivity of the WAIS to collapse.”


Speaking to Science magazine, Boston College paleoclimatologist Jeremy Shakun said that it might not be much for the West Antarctic ice sheet to move, which could cause ocean levels to rise as much as 8 feet per century.

If the findings hold up, it would confirm “of the West Antarctic ice sheet would not need a huge nudge to budge,” Shakun told the news outlet. That could indicate, “the large increase in the mass loss observed in the last decade or two is perhaps the beginning of that process instead of a short-term blip.”

The study’s lead author, Oregon State glacial geologist Anders Carlson, said: “We had a lack of evidence. I think we have the evidence of absence now.”

The Alfred Wegener Institute, suggests that the West Antarctic ice sheet, is not very stable and took out a 2016 research that suggested that it could disappear in as little as 1000 years.

“A business-as-usual scenario of global warming, the collapse of the West Antarctic could go very fast and the West-Antarctic ice masses may disappear completely in the next 1,000 years,” says John Sutter, the study is the most important author in the comments on the website of the Institute.


The ice sheet originally gone about 125,000 years ago, the study noted, and found that sea levels were more than 19 feet (6 meters) above the current levels.

A study published in June notes that the climate change has led to more than 3 billion tonnes of ice melt from Antarctica is the last, 25 years ago, according to the USA Today report.

In September, NASA unveiled its new $1 billion satellite, ICESat-2, to mankind a stronger, data-backup-vision of exactly how fast the Earth’s ice is melting.

According to the government space agency, and the melting of the ice in Greenland and Antarctica has increased the global sea level more than a millimeter per year, which is one third of the total increase.
