I make no secret of the fact that I was not a big Hillary Clinton supporter, but I thought in the two-way race between her and Donald Trump, that she should have been the president. But Trump promised a lot of things. And now he's six months in and hasn't passed a piece of legislation yet. Now, I personally have said we should help him. I didn't vote for him. I didn't think he was the right person. But once we have an election and he gets elected, then we have a responsibility as citizens to help him.

Fifty percent of the world's population lives in cities. In a couple of decades, 70 percent of the world's population will be living in cities. Cities are where the problem is. Cities are where the solution is, where creativity exists to address the challenges and where they have most impact. This is why, in 2005, the C40 was founded, an organization of cities that address climate change. It started with 18 cities; now it's 91. Cities simply are the key to saving the planet.
