Last month, Susan Hubbard and Margaret Torn of the Earth Sciences Division, and scientists from several other Department of Energy national laboratories, traveled to two small Alaskan towns. Near Council, on the Seward Peninsula, the permafrost is already thinning due to climate change. Hundreds of miles north near Barrow, the northernmost town in the U.S., the permafrost is frozen thick. The scientists are developing The Next-Generation Ecosystem Experiment, a multidisciplinary effort to answer an urgent question: How will a changing climate affect the Arctic, and how will this in turn affect the planet’s climate?
