France calls on world leaders to give Paris climate deal 'new push'

Ratifying the agreement at a meeting in New York to enshrine it in international law is the next step, says France's foreign minister Laurent Fabius

World leaders should give international efforts to fight global warming a new push by ratifying the historic Paris climate deal in person, according to France's foreign minister.

Laurent Fabius, who steered December's UN talks, wants heads of state to ratify the accord at a meeting in April in New York, so that it can be enshrined in international law. Nations accounting for more than 55% of global emissions must formally sign up before the Paris agreement can be made official.
