"It is increasingly clear that doubling CO2 is unlikely to increase global temperature more than about one degree Celsius, not the much larger values touted by the global warming establishment. In fact, CO2 levels are below the optimum levels for most plants, and there are persuasive arguments that the mild warming and increased agricultural yields from doubling CO2 will be an overall benefit for humanity. Let us debate and deal with serious, real problems facing our society, not elaborately orchestrated, phony ones, like the trumped-up need to drastically curtail CO2 emissions."
