On November 30, the Smithsonian Channel will air the film Mass Extinction: Life at the Brink featuring UC Berkeley researchers Walter and Luis Alvarez, as well as UCMP’s Tony Barnosky; and Stanford University’s Elizabeth Hadly and Jon Payne. The film describes what we know about the Cretaceous-Paleogene boundary, how we know it, and how the Cretaceous-Paleogene and end-Permian mass extinctions relate to our present extinction crisis. Learn more at smithsonianchannel.com and tangledbankstudios.org.

Watch newscenter.berkeley.edu this week (November 24) for a news release about Tony Barnosky and his work regarding mass extinctions.

See Tony’s recent blog entitled “Preventing the Sixth Mass Extinction Requires Dealing With Climate Change” on The Huffington Post website.

Also see two free educational videos produced by the Howard Hughes Medical Institute (HHMI) that are available on HHMI’s BioInteractive website as well as YouTube. One features Barnosky and UCMP alum Kaitlin Maguire measuring mammal extinctions in Oregon’s John Day Fossil Beds, and in the other, Stanford’s Elizabeth Hadly and biologist Sean Carroll track the effects of climate change in Yellowstone National Park.
