"It [the IPCC report] has finally ended all serious debate over climate change.

There can be no more denial. Global warming skeptics and deniers now find themselves in the company of creationists, flat-Earthers and those who dispute the scientific consensus that HIV is the cause of AIDS."

While introducing a mostly excellent weekend package on climate change, Globe and Mail Editor-in- chief Edward Greenspon says, "We are in the business of promoting debate, not dogma...

TVO Producer Daniel Kitts makes the case in the Globe and Mail online edition for not giving climate change "skeptics" equal time.

But he misses a couple of arguments, at least.

First, if you surveyed all those legitimate scientists who accept or contest the theory of anthropogenic global warming and then quoted them proportionately, the deniers would get to comment, but only very, very rarely.

Choosing one person on one side and one on the other - as journalists so often do - makes it appear that the scientific community is evenly divided, that there is a hot debate. As Naomi Oreskes demonstrated in Science , no such debate exists in serious scientific literature.
