Over at the excellent libertarian blog Clasically Liberal, CLS points to a story in the Edmonton Journal to try to poke hole in the claim that there is a scientific consensus on global warming:
Only about one in three Alberta earth scientists and engineers believe the culprit behind climate change has been identified, a new poll reported today.
The expert jury is divided, with 26 per cent attributing global warming to human activity like burning fossil fuels and 27 per cent blaming other causes such as volcanoes, sunspots, earth crust movements and natural evolution of the planet.
A 99-per-cent majority believes the climate is changing. But 45 per cent blame both human and natural influences, and 68 per cent disagree with the popular statement that “the debate on the scientific causes of recent climate change is settled.”
I know it’s lazy/sloppy to use Wikipedia as a reference, but check here for a list of national and international scientific organizations who’s official position is that human actions are very likely the cause of global warming. The article also notes: “With the July 2007 release of the revised statement by the American Association of Petroleum Geologists, no remaining scientific body of national or international standing is known to reject the basic findings of human influence on recent climate.” (Emphasis mine.)
If you think the Edmonton study pokes any holes in the claim that there is a scientific consensus, perhaps you should also read the Wikipedia entry on scientific consensus.
