Performing high-altitude research on global warming

August 03, 2006
From the SF Chronicle's science writer Carl Hall, featuring CNR alumnae Ann Dennis and Connie Millar:

Stately corpses of bristlecone pine trees, some dead for 2,000 years but still refusing to lie down, stood watch last week as botanist Ann Dennis and a crew of naturalists stepped off plots on the shoulders of 14,246-foot White Mountain Peak near the Nevada border.

Working more than 10,000 feet above the sunbaked floor of the Owens Valley, the scientists were transforming one of California's highest mountaintops into a living laboratory of climate change.

Dennis and her colleagues are part of a global network of mountain-climbing researchers, all using precisely the same methods to observe the impact of global warming at high altitudes on five continents simultaneously....
