Will These Ancient Trees Survive a Drying West?
Deep within the trunks of an ancient grove of big-cone Douglas fir trees lie traces of a megadrought 450 years in the past. But signs of the worst drought these trees have ever seen can now be found just beneath their bark. Daniel Griffin is an assistant professor in Geography at the University of Minnesota where he studies climate and ecosystem change — past and present — through data collected from tree rings. His op-ed is an insightful, gripping, and beautifully written piece rich in illustrations.
