WASHINGTON (AP) — For Republican presidential contenders who once supported combating global warming, the race is heating up.

Faced with an activist right wing that questions the science linking pollution to changes in the Earth's climate and also disdains big government, most of the GOP contenders have stepped back from their previous positions on global warming. Some have apologized outright for past support of proposals to reduce heat-trapping pollution. And those who haven't fully recanted are under pressure to do so.

The latest sign of that pressure came Thursday when New Jersey Gov. Chris Christie said he was pulling his state out of a regional agreement to reduce greenhouse gases, saying it won't work. While Christie, a rising GOP star, has said he won't run for his party's presidential nomination, some in the party continue to recruit him.
