Over 165 countries to sign Paris Climate deal at UN
UNITED NATIONS: (APP) United States World leaders gather at the United Nations on Friday to sign the Paris climate deal and get the ball rolling on a quick entry into force to start beating back global warming .
French President Francois Hollande and Canada's Justin Trudeau will join US Secretary of State John Kerry for the ceremony attended by more than 165 governments, the largest ever one-day signing of an international agreement.
Held on Earth Day , the ceremony comes four months after the hard-won deal was clinched in Paris and marks the first step toward binding countries to the promises they made to cut greenhouse gas emissions.
Oscar winner and environmental activist Leonardo DiCaprio will be on hand to praise leaders for signing, urge others to do the same and appeal to all to turn their commitments into action.
