President Obama and Chinese President Xi Jinping together signed documents committing their nations to the Paris climate change pact on Saturday while meeting in Hangzhou, China. This marks a major step toward the deal’s required approval from 55 countries and 55 percent of the world’s carbon emitters (China and the United States together are responsible for 38 percent of carbon emissions). Because the agreement is not considered a treaty, it does not require the approval of the U.S. Senate; and it will require the U.S. to cut emissions levels by 26 percent over the next nine years. “I believe that history will judge today’s efforts as pivotal,” Obama said at the signing ceremony.
