WASHINGTON — A coalition of conservative evangelical leaders wants to enlist 1 million Christians to sign a statement questioning whether human-caused global warming is a real threat and arguing that restrictive environmental policies harm poor people.

The "We Get It!" campaign is the latest development in an ongoing disagreement among evangelicals about climate change.

"Our stewardship of creation must be based on Biblical principles and factual evidence," the statement says.

Several leaders and groups on the evangelical right back the campaign, including James Dobson of Focus on the Family, Richard Land of the Southern Baptist Convention's Ethics and Religious Liberty Commission, Institute on Religion and Democracy and Cornwall Alliance for the Stewardship of Creation.
