This year may go down as one of the more consequential years for action to prevent the worst effects of climate change. I have written in the past about why fighting climate change is proving to be such a challenge, but an end-of-the-year reflection on what we are getting right might make for a refreshing change.The good news is that while global emissions continue to grow, 2014 saw a great deal of progress toward putting in place the policies and infrastructure necessary to eventually reverse that trend.
