Widespread forest mortality events of many tree species in the last two decades prompt concerns that drought, insects, and wildfire may devastate forests in the coming decades. In this talk, I will give an overview of what we have learned so far about recent drought-induced tree mortality events in the West, covering our current understanding of the physiology, ecology, and predictive capability of these events.
William Anderegg grew up in western Colorado hiking, backpacking, hunting, and fishing in the forests he now studies. His research focuses on western US forests and climate change. He received his Ph.D. from the Department of Biology at Stanford University and worked as a NOAA Climate and Global Change Postdoctoral Fellow at Princeton University. He is currently an Assistant Professor in the Department of Biology at the University of Utah.

What date was this talk given? How up to date is the info. I note that some talks are published recently but were given 2 or 3 years ago. Thanks

The faster we create the conditions for our extinction, the faster the planet can get back to equilibrium.

Precautionary principle anyone? I would hate to find, for example that long growing trees like Coast Redwoods go past a no return. Remember Julia Butterfly Hill, Coevolving species protector of Luna. All of the creation is a wonder to protect and not equivocate about the need for more study but meanwhile we continue climate change as a normal.

When a scientist says this research is particularly close to his heart you need to really question his analysis. Most of us have had partners who were particularly close to our hearts and it was a long time before we were able to look at them analytically. That might be an extreme case but that's why science does not operate near the heart but through rigid unbiased observation of data.

"Exciting"? His tone is awfully glib considering the devastating effects of a climate that is warming far more rapidly than any climate models or even the most pessimistic predictions. Not to mention the over 60 positive feedbacks causing cascading and exponential climate effects, such as the melting of methane clathrates expelling more and more CO4 into the oceans and atmosphere resulting in more warming which causes the melting of more methane clathrates, resulting in more CO4. Methane causes far more warming than CO2 in the first two decades, and warming from a now over a 200% increase in methane was not even factored into the IPCC report models and data. If you look at the most recent climate data and studies, things are far worse than you think. "Climate change may be escalating so fast it could be 'game over', scientists warn - New research suggests the Earth's climate could be more sensitive to greenhouse gases than thought, raising the spectre of an 'apocalyptic side of bad' temperature rise of more than 7C within a lifetime" www.independent.co.uk/news/science/climate-change-game-over-global-warming-climate-sensitivity-seven-degrees-a7407881.html
