A new study says no matter how much the world cuts back on carbon emissions, a key and sizable chunk of Antarctica is essentially doomed to an unavoidable melt.
Though the full melt will take hundreds of years, it will be enough to reshape where and how people live in the future.Though the full melt will take hundreds of years, slowly adding nearly 6 feet to sea levels, it will be enough to reshape where and how people live in the future, the study’s lead author said.
While past studies have talked about how dire the situation is, Naughten was the first to use computer simulations to study the key melting component of warm water melting ice from below, and the work looked at four different scenarios for how much carbon dioxide the world pumps into the atmosphere. In each case, ocean warming was just too much for this section of the ice sheet to survive, the study found.which float over the ocean in this area of Antarctica that is already below sea level.
“I think it’s unavoidable that some of this area is lost. It’s unavoidable that the problem gets worse,” Naughten told The Associated Press. “It isn’t unavoidable that we lose all of it because sea level rise happens over the very long term. I only looked in this study up to 2100. So after 2100, we probably have some control still.''
However, she said, that is a slow process that would play out through the next few hundred years through the 2300s, 2400s and 2500s.
