If the temperature of your living room fluctuated by 2 degrees, you probably wouldn't flinch. But if global temperatures climb by that much, the result could be "catastrophic and irreversible." That's according to the Intergovernmental Panel on Climate Change. The U.N. climate talks being held in Paris starting November 30 aim to avoid that scenario.

U.S. President Barack Obama will be there as will leaders from China and the United Kingdom. There will also be a city councilman, and former mayor, from Boulder in attendance --Matt Appelbaum. He'll be joining a number of representatives from cities around the world in Paris. He sat down to chat with CPR's Ryan Warner before his trip.
