Listen to this 55 minute webinar (voice presentation with slideshow) by Professor Kevin Anderson, on Climate Change: Going Beyond Dangerous. Professor Anderson is Deputy Director of the Tyndall Centre for Climate Change Research and holds a chair in Energy and Climate Change at Manchester University, and is an advisor to the British Government on climate change (see Wikipedia).
Kevin Anderson explains in simple language what we are facing in our climate future - a four degree world perhaps as soon as 2060 and a 6 to 8 degree world by the end of the century. He is brutally honest and straight forward in his assessments of where we are at with mitigation and the options open for humanity. Climate negotiations have dithered since 1992, and have left no easy options for us. The longer we delay, the more difficult it will be to respond to climate change.
It is only through knowing the dire extent of the situation that we can take the actions necessary to possibly avoid the worst climate impacts.
