The former vice president and climate champion, Al Gore, has called on Barack Obama to seize the moment and use his reelection victory to push through bold action on climate change.

The president has faced rising public pressure in the wake of superstorm Sandy to deliver on his promise to act on global warming.

But none of those calling on Obama to act carries the moral authority of Gore, who has devoted his post-political career to building a climate movement.
