Antarctica’s melting ice could become a cause for the rising of ocean levels by one meter before 2100, a new study has revealed.


A new study noted that, if greenhouse emissions continue at the current rate, the rise in sea levels could double than what was previously expected.

Antarctica’s melting ice could cause the sea levels to rise by 15 meters by 2500. Rob DeConto, of the University of Massachusetts, one of the two authors of the study, said the findings reveal the projection for the rise of sea levels “nearly doubles” than that of previous projections, which DeConto added were based on “minimum contribution from Antarctica.”

David Pollard, of Penn State University, the second author of the study, said, “Sea level has risen a lot — 10 to 20 meters — in warm periods in the past, and our ice sheet models couldn’t make the Antarctic ice sheet retreat enough to explain that. We were looking for new mechanisms that could make the ice more vulnerable to climate warming to explain past sea level rise.”

Much of the severity will be faced by major cities and coastal areas across the world, with hundreds of millions of people who will have to shift to higher ground, according to ABC News. The study was published in the journal Nature.

By the end of the century, sea levels could rise by as much as two meters if efforts are not made to tackle greenhouse emissions, the Washington Post reported.

Last year, world leaders gathered in Paris to discuss ways to combat the dangerously growing effects of climate change, but individual countries have not taken the steps to ascertain the realization of them. High levels of Antarctic melting, due to increasing pollution, could cause the sea levels to rise by as much as a dozen of feet in the next few centuries.

Limiting greenhouse emissions is empirical; and not doing so can pose dangerous consequences beginning 2100, Ben Strauss, director of the program on sea level rise at Climate Central, said. He also noted that several coastal areas are at high risk. “Under the high emissions scenario, the 22nd century would be the century of hell,” he said. “There would really be an unthinkable level of sea rise. It would erase many major cities and some nations from the map … That century would become the century of exodus from the coast,” he said.

An independent analysis carried out by Climate Central showed that in the major East Coast cities, where sinking of land is occurring as the sea levels are rising, melting of Antarctica ice could result in sea levels rising by five and six feet in this century.
