Is "Global Warming" an Evangelical Issue?

I mentioned global warming the last issue without further comment, because it seemed unimportant to the cuteness of the post. But now it appears that I have to comment. the New York Times is reporting that a group of 86 Evangelical leaders, including Rick Warren who is the author of the "Purpose Driven Life" used by many churches in the last year or so, has endorsed the "Evangelical Climate Initiative" to push legislators to reduce greenhouse emissions and battle global warming.

Global warming is a major issue on the political front, and personally I am not yet convinced that human activity has any role to play in the cyclical progress of warm climate to ice age to warm climate seen in the history of this planet. But it seems to me that either way this is not an issue that Evangelicals should be grouping together about. Not that Evangelical Christians can not have strong beliefs about this, or that they should not express those beliefs. But forming a uniquely religious organization to deal with global warming is wrong-headed. There are plenty of existing organizations to join which address this issue. Let's keep our Christian leaders focussed on Christ and Him crucified and risen again, and leading their people in that way.
