The Greenland ice sheet has shed an estimated 1 trillion tons of ice since 1900, with a doubling in the rate of ice loss from 2003 to 2010, according to a new study published in the journal Nature on Wednesday.
The study, which was the work of 16 authors from five countries, used aerial imagery of Greenland from the 1980s to trace back the maximum extent of the Greenland Ice Sheet during a period of time when much of Greenland was colder than it is now, which was known as the Little Ice Age.
The Little Ice Age lasted from about 1450 to 1850, which was when the Greenland Ice Sheet was at its maximum extent during the past 1,000 years.
Researchers led by Kristian Kjeldsen from the Center for GeoGenetics at the Natural History Museum of Denmark sought to obtain direct measurements of Greenland's glaciers prior to 1992, rather than relying on computer modeling to arrive at estimates of historical ice sheet behavior.
