Some people accuse me of exaggeration, so let me be clear. Those people seek nothing less than the complete and utter destruction of the American way of life.

I would distinguish between Donald Trump and the United States of America. Although he is president, he does not speak for the country on the climate change, and that was vividly illustrated in the aftermath of his speech pulling the US out of the Paris Agreement. Almost immediately, not only did the rest of the world double down on its commitments, but also here in this country, governors, mayors, business leaders, they said, we're still in the Paris Agreement, and they're doubling down. A lot of cities have now made a decision to go 100% renewable energy.
