AGW Myths

Despite claims that global warming will reduce human well-being in developing countries, there is no evidence that this is actually happening.  Empirical trends show that by any objective climate-sensitive measure, human well-being has, in fact, improved remarkably over the last several decades.  Specifically, agricultural productivity has increased; the proportion of population suffering from chronic hunger has declined; the rate of extreme poverty has been more than halved; rates of death and disease from malaria, other vector-borne diseases, and extreme weather events have declined; and, consequently, life-expectancy has more than doubled since 1900.
And while economic growth and technological development fueled mainly by fossil fuels are responsible for some portion of the warming experienced this century, they are largely responsible for the above-noted improvements in human well-being in developing countries (and elsewhere).  The fact that these improvements occurred despite any global warming indicates that economic and technological development has been, overall, a benefit to developing countries [pp. 181-182].
