Yet, it was also a year full of progress in the effort to cut the carbon pollution fueling the problem. Solar, wind and energy efficiency continued to make big gains here in the state. And, for the first time in history, America is growing the economy at the same time emissions are decreasing. But we’ve still got the biggest challenges ahead of us.

Will our Sens. Udall and Bennet and Gov. Hickenlooper push for the strongest possible limits for carbon pollution this year? Time will tell, but if 2014 is anything like this last year, we’ve got reason to hope.
