If you live somewhere that doesn't have a mayor, check with your town/village government. The town manager here in Arlington, Mass., wasted no time in assuring us (on behalf of the board of selectmen*) that the town is committed to the Paris Climate Agreement.

*Yes, the term is archaic and suboptimal, but I gather that enough people here find both "selectpeople" and "select board" awkward or irksome that no change is likely.
