WASHINGTON (AFP) - The presidents of France and the United States issued a joint call on Monday for other nations to join them in seeking an "ambitious" agreement to curb climate change.

Presidents Barack Obama and Francois Hollande, writing in an article in the Washington Post and Le Monde, called for support "in pursuit of an ambitious and inclusive global agreement" to reduce greenhouse gas emissions "through concrete actions" at a climate conference in Paris in 2015. Hollande will begin a visit to the United States on Tuesday.
