by Ronald Bailey

“Details like sea level rise will continue to be debated by researchers, but if the debate over whether or not humanity is contributing to global warming wasn’t over before, it is now. The question of what to do about it will be front and center in policy debates for the next couple of decades. How strongly humanity may want to mitigate future climate change and at what cost depends on how likely the worst case projections turn out to be. … However, as the new IPCC Summary makes clear, climate change Pollyannaism is no longer looking very tenable.” (02/02/07)
