Over 130 countries will sign UN climate agreement on April 22
The UN says a record number of more than 130 countries will sign the landmark agreement to tackle climate change at an April 22 ceremony at UN headquarters.
Secretary-General Ban Ki-moon is hosting the ceremony on the first day that the agreement reached in Paris in December opens for signing.
The UN says the signing by over 130 countries, including more than 60 world leaders, would surpass the previous record of 119 signatures on the opening day for signing an international agreement, set by the Law of the Sea treaty in 1994.
Signing is the first step. The agreement will enter into force 30 days after at least 55 countries, accounting for 55% of global greenhouse gas emissions, deposit their instruments of ratification or acceptance with the secretary-general.
The UN chief, French President Francois Hollande and French environment minister Segolene Royal, who is in charge of global climate negotiations, have invited leaders from all 193 UN member states to the event.
"Paris was historic," Mr Ban said. "But it's only the beginning. We must urgently accelerate our efforts to tackle climate change."
The agreement sets a collective goal of keeping global warming below 2C (3.6F) compared to pre-industrial times, and to pursue efforts to limit the temperature rise to 1.5C (2.7F). It requires all countries to submit plans for climate action and to update them every five years, though such plans are not legally binding.
