Recent droughts could be new normal, may lead to massive tree death, study suggests

Source: Phys.org - 10/15/12

Evidence uncovered by a University of Tennessee, Knoxville, geography professor suggests recent droughts could be the new normal. This is especially bad news for our nation's forests.

For most, to find evidence that recent year's droughts have been record-breaking, they need not look past the withering garden or lawn. For Henri Grissino-Mayer, he looks at the rings of trees over the past one thousand years. He can tell you that this drought is one of the worst in the last 600 years in America's Southwest and predicts worst are still to come.

Grissino-Mayer collaborated with a team of scientists led by Park Williams of Los Alamos National Laboratory and others from the U.S. Geological Survey, University of Arizona and Columbia University to evaluate how drought affects productivity and survival in conifer trees in the Southwestern U.S. Their findings are published this month in Nature Climate Change.
