The findings of a new study on the large impact crater that was found under Greenland’s Hiawatha Glacier in 2018 suggest that the impact that formed the 31-kilometer (19.3-mile) crater occurred quite recently (geologically speaking, that is), at a time when the region was covered in a mile-thick sheet of ice, making
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 researchers
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.
