Harvard scientists study tree rings see climate change clues – Harvard Gazette

About a decade ago, Pederson and David Orwig, a senior forest ecologist and the co-manager of the Tree Ring Lab, showed this isn’t always the case. They presented evidence that droughts and harsh spring frosts from 250 years ago affected different forests across hundreds of miles in the Southeast. The disturbances abruptly killed some trees but accelerated the growth of others.

“This study will hopefully give us more insight about that relationship between climate events and forest disturbance so that we can better predict forest response under different climate scenarios,”…
