Ice Age climate records from an Arizona stalagmite link the Southwest's winter precipitation to temperatures in the North Atlantic, according to new research. The finding is the first to document that the abrupt changes in Ice Age climate known from Greenland also occurred in the southwestern U.S., said co-author Julia E. Cole of the University of Arizona in Tucson. "It's a new picture of the climate in the Southwest during the last Ice Age," said Cole, a UA professor of geosciences. "When it...

California experienced centuries-long droughts in the past 20,000 years that coincided with the thawing of ice caps in the Arctic, according to a new study by UC Davis doctoral student Jessica Oster and geology professor Isabel Montañez. The finding, which comes from analyzing stalagmites from Moaning Cavern in the central Sierra Nevada, was published online Nov. 5 in the journal Earth and Planetary Science Letters. The sometimes spectacular mineral formations in caves...

Geologists say a discovery in a cave near Jerusalem suggests climate change may have caused the fall of the Roman and Byzantine Empires. Geochemical analysis of a stalagmite from Soreq Cave in the Stalactite Cave Nature Reserve reveals increasingly dry weather from A.D. 100 to A.D. 700 that coincided with the fall of both Roman and Byzantine rule in the region, the University of Wisconsin-Madison said Friday. Geology graduate student Ian Orland said oxygen isotope signatures and impurities...

A stalagmite discovered in a U.S. cave has yielded detailed geological data on 7,000 years of eastern North America climate cycles. The Ohio University-led study confirms that during periods when the Earth received less solar radiation a series of century-long droughts occurred. Researchers led by Assistant Professor Gregory Springer said the stalagmite preserved climate conditions over periods as brief as a few years. The scientists said they found evidence of at least seven major droughts...
