Biological Evidence for Climate Change from the Pacific Northwest

This is an informative and entertaining talk about the impact of climate change on the forests of the Cascades and Olympic Mts. given by University of Washington professor Dave Peterson. I especially liked the mention of corroborating, interdisciplinary evidence. While we sometimes hear about a consensus of expert opinion, we don't hear often enough about the complimentary nature of the data from different scientific fields. One could argue this agreement is the most convincing bit of proof we have for the effect our emissions are having on climate. And it doesn't hurt when the speaker has a good sense of humor and an infectious passion for the subject matter. Have a watch.
