CNN moderators ask climate questions in the Democratic and Republican presidential debates in Florida

Last week, the Democratic and Republican presidential candidates participated in debates in Florida. A bipartisan group of 21 Florida mayors wrote to the debate moderators to argue it would be "unconscionable for these issues of grave concern for the people of Florida [climate change and sea level rise] to not be addressed." The moderators of both debates listened, and asked the candidates questions about climate change - including by far the most substantive climate question posed to the Republican candidates thus far.
