The grant will allow GCRG to operate eddy covariance flux towers at Barrow, Atqasuk and Ivotuk for the next 3 years. Read more about the project here. GCRG will work with the National Aeronautics and Space Administration’s Jet Propulsion Lab to measure the greenhouse gas effect on the Arctic. The research team will collect data that will provide unprecedented experimental insights into Arctic carbon cycling, especially the release of the important greenhouse gases such as carbon dioxide and methane. The study is . . . → Read More: GCRG Heads for the Skies with NASA-Funded Research The 17th Annual Albert W. Johnson University Research Lecture Walter C. Oechel, Ph.D. “Global Change: Is the World Beyond Repair?” March 21, 2007 | 3:00-4:30pm | Aztec Athletic Center Auditorium Flyer Recently, it was another beautiful, sunny day out on the Arctic tundra. Scientists say the Arctic is melting — and fear it could help send Earth into a global warming tailspin. It may sound nicer that way — but it’s a big problem for the Earth. Scientists say the warm weather adds to global warming . . . → Read More: What is a “Feedback Loop?”: Dr. Oechel on ABC News Tidal waves, tornadoes, and the big freeze. The Day After Tomorrow is the latest disaster movie to hit the big screen. But how much of it is based on fact? We’ll talk about the realities of global warming. Listen to a recording of the show Dr. Walter C. Oechel is one of eight scientists selected to receive NSF Director’s 2004 Award for Distinguished Teaching Scholars.
