Tree Ring Data
Climate scientists have long suspected that global warming has an influence on the Pacific Ocean El Niño- La Niña cycle (El Niño-Southern Oscillation), but instrumental records tracking the shift between above- and below average sea surface temperatures don’t go back far enough to provide context for any recent changes in the pattern.
Long before the current drought or the continuing conversation about global warming, before the Dust Bowl, the climate in large portions of the American West was far drier than modern humans have become accustomed to. The 19th and 20th centuries, ancient tree rings show, were a relative oasis of settlement-friendly weather.
When the smoke finally clears and new plant life pokes up from the scorched earth after the wildfires raging in the southern Rockies, what emerges will look radically different than what was there just a few weeks ago.
November 6, 2011--Scientists find evidence of ancient megadrought in Southwestern U.S. (Science Daily)
A new study at the the University of Arizona's Laboratory of Tree-Ring Research has revealed a previously unknown multi-decade drought period in the second century A.D. The findings give evidence that extended periods of aridity have occurred at intervals throughout our past. Almost 900 years ago, in the mid-12th century, the southwestern U.S.

Rocky Mountain snowpack is lighter and melting sooner in the past 30 years than in previous centuries, according to a new federal study. The U.S.
A new tree ring study spanning more than 1,200 years is helping archaeologists pinpoint the exact dates of ancient mega-droughts that may have been key factors in the decline of major pre-Hispanic cultures in Mexico and Central America.
December 13, 2010--Hot with decades of drought: Expectations for Southwestern United States (Science Daily)
An unprecedented combination of heat plus decades of drought could be in store for the Southwest sometime this century, suggests new research from a University of Arizona-led team. A 60-year drought like that of the 12th Century could be in our future. To come to this conclusion, the team reviewed previous studies that document the region's past temperatures and droughts.
Simply bringing water from the Colorado River to the Arkansas River basin in Colorado does not improve protection against drought. The surprising finding was shared last week at the Arkansas Basin Roundtable by climate researchers from Western Water Assessment, a hybrid agency that combines Nation Oceanic and Atmospheric Administration and University of Colorado resources.
