By speeding the transition to cleaner energy, we can improve the lives of billions of people, while also reducing the risks we face from a changing climate.

What the Democrats have to understand is that while we do need to reform our regulation and we do need more restrictions, it is true that it is capitalism and free enterprise and companies that create jobs and wealth for every American.

We have reduced poverty in the world by 50% since the year 1970 - the number of people who go to bed hungry, the number of people that have to sleep without a roof over their heads, the number of people that are illiterate.The world is better.

People vote against their own interests that all the time. But when you do the polling in the U.S., it has gone from less than 50 percent who thought climate change was real to 70-odd percent. And if you listen to the Republicans in Congress, they used to say, "Oh, climate change doesn't exist." Then they switched to "Well, it exists, but it's not man-made," to "Well, I'm going to address the issue." Why? Because when they go home, the local constituent says, "Wait a second. What are you talking about? We just had a flood. We haven't had rain in a long time." They can't get away from it.

In New York City, a lot of people think "the great outdoors" is the area between your front door and a taxi cab.

I cannot for the life of me understand why the American market keeps going up. Our economy has some real challenges. The infrastructure's falling apart. We're destroying jobs with technology. We are keeping the best and the brightest from around the world from coming to America to create new jobs and create new businesses. All of those things would give you pause to worry about the future.

My personal view is, why don't you get out there and try to do something about the things that you don't like, create the jobs that we are lacking, rather than just yell and scream. But if you want to yell and scream, we'll make sure you can do it.
