The right's civil war over science goes to Tennessee

America's right flank is at war with itself over climate-change science, and the latest battle is this week in Nashville.

Driving the news: The American Legislative Exchange Council, a policy group of conservative state lawmakers and companies, holds a meeting Thursday in Nashville, Tenn. Members of one of its task forces are expected to vote on whether to draft a proposal calling on the Environmental Protection Agency to withdraw a scientific finding that greenhouse gas emissions endanger public health and welfare.
