In 2005, a researcher from Arizona\u2019s tree-ring lab named Matthew Salzer noticed an unusual trend in the most recent stretch of bristlecone tree rings. Over the past half century, bristlecones near the tree line have grown faster than in any 50-year period of the past 3,700 years, a shift that portends \u2018an environmental change unprecedented in millennia,\u2019 according to Salzer. As temperatures along the peaks warm, the bristlecones are fattening up, adding thick rings in every spring season. Initially there was hope that the trend was local to the White Mountains, but Salzer and his colleagues have found the same string of fat rings \u2014 the same warming \u2014 in three separate bristlecone habitats in the western US. This might sound like good news for the trees, but it most assuredly is not. Indeed, the thick new rings might be a prophecy of sorts, a foretelling of the trees\u2019 extinction.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>The vanishing groves Bristlecone pines, dendrochronology, and climate change.
