Global Warming: Is the Science Settled Enough for Policy?

July 24, 2008 presentation by Stephen Schneider for the Stanford University Office of Science Outreach's Summer Science Lecture Series.

Professor Schneider discusses the local, regional, and international actions that are already beginning to address global warming and describe other actions that could be taken, if there were political will to substantially reduce the magnitude of the risks.

The Stanford Summer Science Lecture Series is a set of informal lectures about cutting edge research from four of Stanford's most esteemed professors.

Combating climate change may not be a question of who will carry the burden but could instead be a rush for the benefits, according to new economic modeling presented at âClimate Change: Global Risks, Challenges & Decisionsâ hosted by the University of Copenhagen.

Contrary to current cost models for lowering greenhouse gas emissions and fighting climate change, a group of researchers from the University of Cambridge conclude that even very stringent reductions of can create a macroeconomic benefit, if governments go about it the right way.

âWhere many current calculations get it wrong is in the assumption that more stringent measures will necessarily raise the overall cost, especially when there is substantial unemployment and underuse of capacity as there is todayâ, explains Terry Barker, Director of Cambridge Centre for Climate Change Mitigation Research (4CMR), Department of Land Economy, University of Cambridge and a member of the Scientific Steering Committee of the Congress.

But is the science settled? I have seen the failures of the computer simulations and the correlation with sunspot cycles. Can anyone prove to me that this is.....settled?
