World Leaders Open Summit Seeking Binding Climate Change Action by VOA News More than 150 world leaders gathered Monday in Paris for a U.N. summit with the goal of agreeing to binding measures to address climate change and keep global temperatures from rising to a level with catastrophic impacts. Peru's Environment Minister Manuel Pulgar Vidal, who chaired the last summit, opened the meeting by saying an agreement would show the world that countries can work together against global warming and terrorism. The goal of the summit is to limit average global warming to 2 degrees Celsius, perhaps less, compared to pre-Industrial Revolution levels, by curbing fossil fuel emissions that are blamed for climate change. Just this year, the U.N.'s weather agency says the average global temperature is set to rise by 1 degree Celsius, halfway to the limit the U.N. is seeking to impose. Before the summit opened, U.S. President Barack Obama highlighted the "necessary" coordination in fighting climate change between his country and China as he met with Chinese President Xi Jinping. '' "As the two largest carbon emitters, we have both determined that it is our responsibility to take action," Obama said. "Our leadership on this issue has been vital." Obama will also hold separate talks Monday with India's Prime Minister Narendra Modi. Together, the U.S., China and India account for about half of the world's emissions of carbon dioxide, a gas that traps heat in the atmosphere and that scientists have identified as a leading cause of the rising global temperatures. French President Francois Hollande has warned of obstacles for the 195-nation summit in reaching a compulsory deal in Paris, including the legality of any accord, financing for poorer countries and monitoring of countries' pledges to limit greenhouse gas emissions. So far this year, 183 nations have issued long-term plans to cope with climate change, but difficult negotiations are expected at the summit and related international meetings that run through December 11. An attempt in Copenhagen in 2009 to craft a global deal foundered at an ill-tempered summit, with divisions between rich and poor countries. Ahead of the summit in Paris, hundreds of thousands of protesters joined worldwide demonstrations Sunday calling for adoption of global environmental controls. Activists linked hands in the heart of the French capital amid tight security in the wake of the deadly Islamic State terrorist attacks earlier this month that killed 130 people. Peaceful protests turned violent with police firing tear gas at some demonstrators. More than 200 protestors were detained. '' With French officials banning marches, demonstrators, including U.N. Secretary General Ban Ki-moon, left about 20,000 pairs of shoes on the ground at the Place de la Republique. Demonstration organizers said the shoes weighed four tons and included a pair the Vatican sent on behalf of Pope Francis. France says about 2,800 police and soldiers are securing the Le Bourget conference site, and 6,300 others will deploy in Paris. French Interior Minister Bernard Cazeneuve said nearly 1,000 people believed to pose security risks have been denied entry into France. __________________________________________________________________ [1]http://www.voanews.com/content/world-leaders-open-summit-seeking-bin ding-climate-change-action/3080216.html References 1. http://www.voanews.com/content/world-leaders-open-summit-seeking-binding-climate-change-action/3080216.html
