Greenland researcher Jason Box speaks with science blogger Chris Mooney in the most recent episode of the Climate Desk. Jason Box has been investigating Greenland ice sheet sensitivity to weather and climate as part of 23 expeditions to Greenland since 1994. His time camping on the inland ice exceeds 1 year. Year 2012 brought a deeper level of insight as the scientific perspective shifts to examine the interactions ice with atmospheric and ocean systems, including the role of fire in darkening the cryosphere.
In 2012, Greenland experienced unprecedented warmth and melting across 97% of its area. The Greenland ice sheet covers roughly 85% of the land surface of the island and rises to an average height of 1.6 miles. The immense weight of the ice sheet has pushed the center of the island roughly 1000 ft below sea level. The icy expanse of Greenland, like the rest of the Arctic, not only represents an important climatological indicator, it also is critical to future global climate. Were all of Greenland's ice to melt, global sea level would rise 23 feet. Greenland's ice sheet is slowly melting due to warming temperatures, and there is great concern that this melting will accelerate and contribute to sea level rise of several feet later this century.
