The heavy cost of a non-problem

WUWT
"The bottom line: No policy to abate global warming by taxing, trading, regulating, reducing, or replacing greenhouse-gas emissions will prove cost-effective solely on grounds of the welfare benefit from climate mitigation. CO2 mitigation strategies that are inexpensive enough to be affordable will be ineffective; strategies costly enough to be effective will be unaffordable. Focused adaptation to any adverse consequences of any warming that may occur is many times more cost-effective. Since the premium greatly exceeds the cost of the risk, don’t insure. Every red cent spent now on trying to stop global warming is a red cent wasted. Don’t mitigate: sit back, enjoy the sunshine, and adapt only if and when and to the extent necessary. That, however unfashionable, is the economically prudent and scientifically sensible course."
