Arctic melting heavily influenced by little-studied meteorological phenomena, find scientists led by UMass Amherst - EurekAlert
A team of scientists led by François Lapointe, a research associate at the University of Massachusetts Amherst, has combined paleoclimatic data from the last 2,000 years with powerful computer modeling and in-the-field research on lake sediments and tree rings to show that an understudied phenomenon, known as atmospheric blocking, has long influenced temperature swings in the Arctic. As temperatures warm due to climate change, atmospheric blocking will help drive ever-wilder weather events. The study focused on the Norwegian Arctic archipelago, Svalbard, at the edge of the Arctic Ocean, and was published in Nature Communications.
