Global warming may have pushed Greenland’s ice sheets past a tipping point, with the island having lost ice from its glaciers faster than snowfall could replenish them over the past two decades, according to a new study. Although this trend is expected to worsen as global temperatures increase, the researchersread more

A recently-published study from NASA has revealed that glaciers in West Antarctica’s Marguerite Bay have increased their flow rate, speeding up by up to 25 percent, an event that has accelerated ice loss in the region from 2 to 3 meters (7 to 10 feet) per year to 10 meters (33 feet). Prior to 2008, the flow rates of the four affected glaciers had been stable for two decades, but a major calving event in 1989 left the bay with little to no ice shelf, leaving them with only grounded ice on dry land — a precarious position for its potential to affect sea level rise.
