I like online video content with a little more style than youtube... for my money TED.com provides the most interesting video content in the form of a series of talks from notable people from Clinton to Johnny Chung Lee. But I keep my eye out for other interesting bits and pieces ...
I ran across this from http://uc.princeton.edu/main/
"....The Intergovernmental Panel on Climate Change (IPCC) - co-Laureates, with Al Gore, of the 2007 Nobel Peace Prize - presented a public lecture series on its work entitled: "Inside the Intergovernmental Panel on Climate Change: Science, Policy, and Politics". UChannel is devoting the coming week to this important climate change lecture series, with the publication of one IPCC lecture each day from June 15-20...."
Coming up this week are talks from Isaac Held, V. "Ram" Ramaswamy, Ron Stouffer, Michael Oppenheimer, Jae Edmonds & Gary Yohe all speaking on IPCC activities from the evolution of the science to macroeconomics.
