Here's a thing that closely resembles a monkey wrench.
86 members of the leadership of the Evangelical Christian Right in the US have become signatories to a document entitled "Climate Change: An Evangelical Call to Action".
It's a remarkable document in many ways not least of which is their unqualified acceptance of the scientific basis of human contributions to global warming.
Mostly though it spells even more trouble for the corporate sponsored global warming denial community.
And of course for the political right in North America.
Including Stephen Harper and his dog Rona Ambrose.
