The Greenland ice sheet, measuring around 17 lakh square kilometres has melted beyond the “the point of no return” according to a team of researchers from the United States. Even if global warming, which is the key cause for the depletion of the ice sheet, is contained somehow, the Greenland ice sheet will continue to lose ice. The annual snowfall that the country gets is not enough to replenish it, say the scientists.

Researchers from Ohio State University have also said that once ice sheet melts completely, sea levels will see a drastic rise in fewer than a hundred years. Ian Howat, a co-author of the study and a professor at Ohio State University, said, “We’ve passed the point of no return but there’s obviously more to come. Rather than being a single tipping point in which we’ve gone from a happy ice sheet to a rapidly collapsing ice sheet, it’s more of a staircase where we’ve fallen off the first step but there’s many more steps to go down into the pit.”
