With help from the National Science Foundation, he uses Dendrochronology, or tree-ring dating, to get a snapshot of climate change over time. Stahle can also determine things like the socioeconomic impact of droughts. In fact, in 1998, he made the front page of the New York Times with his discovery that drought could have contributed to the disappearance of colonists in Jamestown. He also found that 1587 was the driest year in 800 years. Stahle runs the Tree-ring Lab at the University of Arkansas and what he and fellow tree-ring researchers are learning is that a trend of global warming began in the 1800s and continues today, brought about by changes in tropical sea surface temperatures of no more than a few tenths of a degree Celsius. Today Stahle is working with hydrologists and government planners in California and throughout Mexico to plan for drought and climate change events.\n
