Antarctic ice melt may be worse

Time has an article by Justin Worland about Antarctic melting:

Melting ice from one of Antarctica’s largest glaciers due to climate change could raise global sea levels by more than two meters, according to new research.
The study, published in the journal Nature, relies on data on past ice levels of the Totten Glacier (photo) in East Antarctica to evaluate the rate of melting. Without intense efforts to stem man-made global warming, the glacier’s melting process could cross the point of no return within the next hundred years, according to report. The result would add more than two meters of sea level rise over the coming several centuries, in addition to several feet of rise from other sources.
“The evidence coming together is painting a picture of East Antarctica being much more vulnerable to a warming environment than we thought,” said study author Martin Siegert, an Imperial College London researcher, in a press release. “This is something we should worry about.”
The contribution of ice melt to sea level rise is the topic of frequent attention from academic researchers, but most studies of Antarctica has focused on the more vulnerable western part of the continent. Another study published in Nature this year shows that global sea levels may rise nearly four feet by the end of this century and forty feet by 2500 without action.
Sea levels rose more than five inches during the twentieth century, faster than any time in the previous three thousand years, according to recent research. While a few inches, or even a few feet, may not sound substantial, higher sea levels will contribute to increased flooding during storms and at high tide, long before they completely sink the world’s many coastal cities.
The world’s leading emitters have all committed to reduce their greenhouse gas emissions in an attempt to slow man-made global warming, but a slew of recent research has led many to wonder whether meeting the goal of keeping temperatures from rising more than 2°C by 2100 will be too little too late.
