This is a segment of The Big Picture with Thom Hartmann, in which climate scientist Professor Michael Mann provides important perspective on the link between climate change and other disasters such as tornadoes. (See also: The Meaning of the Fort McMurray Fire).
Michael Mann is the author of The Hockey Stick and the Climate Wars: Dispatches from the Front Lines, and Dire Predictions, 2nd Edition: Understanding Climate Change (a visually rich summary of the most recent IPCC report) as well as the forthcoming book combining climate science and political cartooning, The Madhouse Effect: How Climate Change Denial is Driving Us Crazy!.
For more information on the science showing the link between climate change and weather patterns, discussed in the video by Professor Mann, see these items:
