Video – Summary of Evidence Linking Extreme Weather to Climate Change

In this video Prof. Jennifer Francis (2013) summarizes some of the massive and growing body of evidence linking extreme weather to climate change. This address was delivered in January 2013 at the 24th annual Glen Gerberg Weather and Climate Summit in Breckinridge (Colorado). It is ironic that Francis’ talk was filmed in Colorado 8 months before the “biblical floods” that devastated that state.
