"Former President Barack Obama says cities, states and nonprofit groups have emerged as 'the new face of leadership' on climate change.

He briefly spoke Tuesday to a summit of mayors from around the world gathered in Chicago to address concerns about climate change since President Donald Trump rejected the Paris climate accord. The mayors signed a charter that echoes portions of the 2015 Paris agreement.

Obama didn’t mention Trump by name, saying only that the U.S. was in an “unusual” position as the sole country to reject the Paris agreement."

NBC 5 Chicago had the story December 5, 2017. [2]
