clipped from wattsupwiththat.com Medieval Warm Period seen in western USA tree ring fire scars Here is just one more indication that despite what some would like you to believe, the MWP was not a regional “non event”. From a University of Arizona press release, Giant Sequoias Yield Longest Fire History from Tree Rings California’s western Sierra Nevada had more frequent fires between 800 and 1300 than at any time in the past 3,000 years, according to a new study led by Thomas W. Swetnam, director of UA’s Laboratory of Tree-Ring Research. A 3,000-year record from 52 of the world’s oldest trees shows that California’s western Sierra Nevada was droughty and often fiery from 800 to 1300, according to a new study led by University of Arizona researchers. Scientists reconstructed the 3,000-year history of fire by dating fire scars on ancient giant sequoia trees, Sequoiadendron giganteum, in the Giant Forest of Sequoia National Park. Individual giant sequoias can live more than 3,000 years.
