In the face of rising levels of human-produced greenhouse gases, one UW professor is part of a Greenland ice-drilling project that aims to better understand future global warming.
Edwin Waddington, UW professor of earth and space sciences, is one of 133 members involved in the North Greenland Eemian Ice Drilling project, working with project leader Dorthe Dahl-Jensen of the University of Copenhagen in Denmark.
Waddington obtained the first ice record of the Eemian, an interglacial period that ended about 115,000 years ago. The record reveals past temperatures, precipitation, and atmospheric gas-levels, and it presents a clearer understanding of global warming.
“It is a major international research effort to figure what in fact was going on in that climate,” Waddington said.
Waddington has conducted previous research about how variations in the Greenland ice can be found through temperature changes and movement of the ice sheet during and after the last interglacial period.
