So what do we really know? We Know that climate is far too complex and too insensitive to greenhouse gases to pretend that we can ‘stabilize’ it by marginal changes in CO2 emissions, whether it is California’s AB32, or the many incarnations of national legislation or global proposals. We know that government policies offer great economic pain and no environmental gain. We also know that the global warming issue has produced intellectual deception and the subversion of the scientific process, widespread corporate rent seeking, and the gross waste of resources that could have gone to improve our environment. But we still have it within our grasp to restore integrity to the science process and to avert unnecessary economic hardship, especially for the world’s poorest who might otherwise aspire to make great strides this century.
