ROUGH CUT (NO REPORTER NARRATION). Story: U.S. President Barack Obama praised the Paris agreement on climate change on Saturday (September 3) while meeting with leaders at the G20 summit in China. But he told them the agreement is not enough to solve the problem. The U.S. leader is making his last scheduled trip to Asia before leaving office. His speech at the summit came on the same day as the U.S. and China ratified the Paris deal to cut climate-warming emissions, marking a major step toward the enactment of the pact as early as the end of the year and setting the stage for other countries to follow suit. The world's two biggest emitters of greenhouse gases made the landmark announcement as heads of state from the Group of 20 biggest economies, or G20, arrived for a summit in the city of Hangzhou.
