Climate-change about-face could cost Mitt Romney

Shift over decade may affect votes of independents

By the time he accepted the Republican nomination for president in August, Romney had completed an about-face, reducing climate science — and President Obama’s efforts to fight global warming — to a punch line. Now, in the waning days of the campaign, Romney’s shift on what had been a backburner election issue could cost him some independent votes.
