Republicans to break rank with party leaders in call for climate change action

At least 10 House Republicans sign on to resolution in mini-rebellion seemingly designed to put pressure on presidential candidates and party leaders

Nearly a dozen Republican members of Congress will break ranks with leaders of their party on Thursday, and call for action against climate change.

The mini-rebellion a week before the pope visits Congress appears timed to ratchet up the pressure on Republican presidential candidates and congressional leaders to soften a party line of casting doubt - or simply denying - the existence of climate change.
