Now that everyone has headed home following the Paris climate talks, it's time to analyze, discuss and figure out next steps. As Bill McKibben wrote, "This agreement won't save the planet. It may have saved the chance to save the planet (if we all fight like hell in the years ahead)."  

Although a group of 195 nations agreed to a landmark climate agreement, it's up to all of us to ensure that governments uphold their stated goal of allowing the earth's temperatures to rise no more than 2 degrees Celsius.
