Gaps in Arctic temperature data caused a misperception that global warming slowed from 1998 to 2012, according to a new study in the journal Nature Climate Change. A University of Alaska Fairbanks professor and his colleagues in China built the first data set of surface temperatures from across the world that significantly improves representation of the […]
A University of Alaska Fairbanks study looking at the physics of tidewater glaciers has yielded new insights into what drives their retreat-and-advance cycles and the role that climate plays in these cycles. Lead author and UAF geophysics doctoral student Douglas Brinkerhoff said the study in Nature Communications reveals that shifting sediments drive the cycles among […]
A study of life and extinctions among woolly mammoths and other ice-age animals suggests that interconnected habitats can help Arctic mammal species survive environmental changes. The study appears online Nov. 2 in the Proceedings of the National Academy of Sciences. Short periods of warm climate in the midst of the last ice age triggered boom-and-bust cycles in the populations of large mammals in […]
