On November 18, with the United Nations Global Warming Conference in Copenhagen fast approaching, U.S. Sen. James R. Inhofe (R–Okla.) took the floor of the Senate and proclaimed 2009 to be "The Year of the Skeptic." Had the senator's speech marked a new commitment to dispassionate, rational inquiry, a respect for scientific thought and a well-grounded doubt in ghosts, astrology, creationism and homeopathy, it might have been cause for cheer. But Inhofe had a more narrow definition of skeptic in mind: he meant "standing up and exposing the science, the costs and the hysteria behind global warming alarmism."
Within the community of scientists and others concerned about anthropogenic climate change, those whom Inhofe calls skeptics are more commonly termed contrarians, naysayers and denialists. Not everyone who questions climate change science fits that description, of course—some people are genuinely unaware of the facts or honestly disagree about their interpretation. What distinguishes the true naysayers is an unwavering dedication to denying the need for action on the problem, often with weak and long-disproved arguments about supposed weaknesses in the science behind global warming.

Minchin and Abetz are probably too fixed in their views to benefit, but the author's treatment of the seven main arguments of sceptics could prove useful to any Coalition representatives who still maintain an open mind on climate change.
What lies behind all this debate are some simple propositions, it seems to me, which often get lost.
Climate change will adversely affect many people, perhaps most of us. CO2 levels affect global temperatures. CO2 levels have increased sharply in the last two centuries. Human activity, particularly industrialisation, population growth, deforestation, is contributing to rising CO2 levels. The evidence for these propositions is pretty strong.
Taken together it all adds up to a compelling case for intervention to reduce our reliance on carbon-sourced energy.
It would be nice if our leaders would leave the rhetoric and hyperbole behind and just get on with it.
