Billy D’Andrea, a Lamont-Doherty Earth Observatory paleoclimatologist and Center for Climate and Life Fellow, is investigating the relationship between environmental change and characteristics of early settlements in Norway’s Lofoten Islands.
On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards, ecology and other subjects with direct applications to the challenges facing humanity.
The Arctic is warming twice as fast as the rest of the planet, and scientists are seeing the effects across ice and ecosystems. Lamont-Doherty Earth Observatory’s Marco Tedesco describes the changes underway.
A new study documents evidence of a massive release of carbon from Siberian permafrost as temperatures rose at the end of the last ice age.
Due to warming climate and increasing human exploitation, far northern forests and the tundra beyond are undergoing rapid changes. In northern Alaska, scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying the responses of trees at the very edge of their range.
In northern Alaska’s Brooks Range, the earth as most of us know it comes to an end. The northern tree line-a boundary that circles all of earth’s northern landmasses for more than 8,300 miles, and forms the planet’s biggest ecological transition zone–runs through here. Scientists from Columbia University’s Lamont-Doherty Earth Observatory are studying how climate may change it, and the tundra beyond.
A new white paper reviews climate impacts already underway in the Arctic, and examines further changes expected to take place even if the world meets the goals of the Paris Agreement. It will be presented today at a meeting at the White House of national-level science ministers and advisors from around the world.
An expedition to the Canadian Arctic and west coast of Greenland is a moving and motivating experience for Lamont-Doherty Earth Observatory climate scientist Maureen Raymo.
Scientists at Columbia University’s Earth Institute will present important findings at the American Geophysical Union fall 2015 meeting, Dec. 14-18–the world’s largest gathering of earth and space scientists.
