Congressman John Shadegg's re-election campaign issued a press release last week that cites Michael Fumento and Steve McIntyre to claim that the "facts" about climate change are wrong. If you missed the McIntyre controversy that ignited the conservative blogosphere and political talk radio, you can find the full context here.

In Shadegg's instance, he adds fuel to the fire by using Al Gore as a foil. It's another example of the "two Americas of climate change perceptions," a partisan divide that Gore has only amplified. Given competing cues from partisan leaders, over the past year, Dems have become more intense in their climate change concern while Republicans remain unmoved.
