ROUGH CUT (NO REPORTER NARRATION) U.N. Secretary-General Ban Ki-moon said on Sunday (September 4) that climate change scepticism is over, a day after the United States joined China to ratify the Paris agreement to curb climate-warming emissions. Climate change sceptics dispute the widely-held understanding that excessive levels of emissions in the atmosphere cause global warming and harm the environment, and have become increasingly side-lined at international summits. U.S. President Barack Obama and Chinese President Xi Jinping delivered the legal instruments to join the Paris agreement to curb climate-warming emissions to Ban on Saturday (September 3), Ban said. Experts are warning the temperature target is already in danger of being breached, with the U.N.'s weather agency saying 2016 is on course to be the warmest year since records began.
