Stubborn isn't a word I would use to describe myself; pigheaded is more appropriate.

We've continued progress in the six months since Trump got elected, and the good thing about what we're doing is that success begets success. As we bring down greenhouse gases, for example, we've closed half of the coal-fired power plants in the country in recent years. There's more impetus to try to close the other half because you can see that it is working. So, you know, I had hoped that Trump would not do that, and it doesn't make any sense to me, but regardless, it is not as cataclysmic as it could be.

New York has been, and will continue to be, a magnet for people from all over the world. This is where the arts, business, research and technology converge to create the world's foremost urban economy.

I tend to be reasonably blunt, maybe a little bit too much. But I just- I always respected people that tell the truth. And I've always wanted people to tell me the truth.

The fact is, the most painful and tragic lesson of the 20th century was that regimes based on racial superiority and religious hatred can't be trusted to keep their word to the international community.

Other ways of looking at the environmental or climate change stuff is to frame it in the context that it is simultaneously a public health issue. One out of eight premature deaths worldwide happens because of air pollution. The worst power plant in America kills 278 people a year and causes 445 heart attacks. So, when we improve air quality we improve our lives, and at the same time we improve the climate as well. We must see climate policy from this perspective and not as an abstract threat that may threaten our survival in 100 years.

If people are not smoking, they'll probably be drinking more.
