Secretary of State John Kerry is headed back to Paris, to join negotiators there trying to break through impasses on a climate change agreement.
Kerry left Washington late Sunday to return to the talks in the French capital that he and President Barack Obama were at just a week earlier.
Kerry, who has made climate change a priority as secretary of state, will arrive in Paris following the weekend adoption of a draft agreement that leaves many key issues unresolved.
Over the course of the week, Kerry and others will have to untangle numerous sticking points in what is envisioned to become a lasting, universal pact to fight global warming.
