This was a big year for climate news, good and bad. In June, the Obama administration took its biggest step yet in the fight against global warming by introducing regulations to limit greenhouse gases from existing power plants. And while there was plenty of anti-science rhetoric and opposition to climate action (no, the polar vortex does not disprove climate change), the year came to a dramatic end with at least three landmark climate-related stories: In September, hundreds of thousands of protesters around the world marched to demand climate action. November’s historic deal between the U.S. and China to curb greenhouse emissions breathed new life into international climate negotiations. And finally, after a series of last-minute compromises, leaders from nearly 200 countries produced the Lima accord, which, for the first time, calls on all nations to develop plans to limit their emissions. All eyes are now on Paris, where next year world leaders will meet in an attempt to work out a major global warming deal.
