WASHINGTON, Dhu-Al-Qa'dah 13, 1438, Aug 05, 2017, SPA -- The Trump administration on Friday officially told the United Nations that the U.S. intends to pull out of the 2015 Paris climate pact. But the State Department's announcement doesn't formally start the process of the U.S. getting out of the voluntary agreement. That's still to come. Still, the department described its communication as a "strong message" to the world, following President Donald Trump's decision in June to leave the accord. "The State Department is telling that U.N. what the president already told the world on June 1 and it has no legal effect," said Nigel Purvis, who directed U.S. climate diplomacy during the Bill Clinton and George W. Bush administrations. Purvis said countries can't withdraw from new international agreements, including the Paris climate one, until three years after they go into effect. The Paris agreement went into effect on Nov. 4, 2016. Then the process takes a year. --SPA 05:11 LOCAL TIME 02:11 GMT www.spa.gov.sa/w460067
