India, Oct. 17 -- The world's widest glacier is melting "more aggressively" than earlier projections said. According to new research by a team of glaciologists, its effect on global sea level rise could be twice the current estimates.

Thwaites Glacier in West Antarctica is known as the "Doomsday Glacier" because its collapse could cause serious damage, as per CNN. The glacier makes it difficult for scientists to predict future sea level rise.

According to CNN, glaciologists from the University of California, Irvine, and NASA's Jet Propulsion Laboratory developed a new ice sheet model to better understand what is happening beneath the glacier.

After updating the model to include a "grounding zone," the scientists found that Thwaites Gla...
