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 […]
New research confirms that the land under the Chesapeake Bay is sinking rapidly and projects that Washington, D.C., could drop by six or more inches in the next century—adding to the problems of sea-level rise. This falling land will exacerbate the flooding that the nation’s capital faces from rising ocean waters due to a warming […]
