"The world has spent $50 billion on global warming since 1990, and we have not found any actual evidence that carbon emissions cause global warming."
--David Evans, a scientific consultant to the Australian Greenhouse Office from 1999 to 2005, writing in The Australian newspaper.
With oil and therefore gas prices high, the economic slowdown and the bursting of the housing bubble, the climate for discussion of global warming (pun intended) has changed.
Whereas before those in the academic community (usually so contrary) may have felt uncomfortable countering Al Gore's "scientific consensus," the aforementioned factors seem to have made more people feel like they can speak their minds about the so-called man-caused-carbon-caused-global-warming.
For the last few years, Bjørn Lomborg seemed like the only one tough enough to stand athwart history, yelling Stop!. His Copenhagen conferences calling attention to other, more pressing needs (easy interventions in lesser developed countries) helped. Highlighting the poor return on investment in the global warming industry helped some more.
There is a sane, rational, cost effective way to talk about all things global warming. And then there's Al Gore's way.
Opt for the former.
