Endangered Animals In Antarctica Become Worse

A new report nearly doubles previous predictions for sea level rise if global emissions continue unabated, portending a doomsday scenario for many of the world’s coastal cities.

The study, published Wednesday in the journal Nature, looks toward the ice sheets of Antarctica, which by themselves may contribute more than three feet to sea level rise by 2100. Taken with other melting regions, including Greenland, seas could rise more than six feet, or two meters, by the end of the century.

David Pollard of Penn State University and co-author Rob DeConto said the “dire” predictions are nearly double those recently used by the Intergovernmental Panel on Climate Change as a worst-case scenario if humanity fails to curb emissions.

Dozens of low-lying metropolises, including Hong Kong, New York and Sydney, would be vulnerable to these rising seas. The authors warn that places like Boston could be faced with a sea level rise of more than five feet in the next century alone. Pollard said other potential effects, similar to the damaging storm surge caused by Hurricane Sandy, could contribute to the ballooning estimates for future flood losses.
