There would be a cost for dumping carbon into our atmosphere and a cap on total emissions. The government must make a clear and firm decision - terminating the idea in our society it is free to pump infinite amounts of carbon into the air. Once that happens, private capital will flow even more aggressively into developing and deploying the alternative, less-polluting technologies.

If you want to understand what's going to happen, you can't look in the rearview mirror into the United States' history, because that's done now. You have to look out at the rest of the world and look at the history of the rest of the world, and what you'll see is demonstrations and counter-demonstrations are going to become the norm. We'll have a big march, then they'll have a big march, we'll have a big rally and they'll have a big rally. That will be one of the features. Again, a pro-regime and pro-opposition media system, that will become a feature.

I'm not asking for more entitlement programs; I'm asking for more enterprise.

Religion has gotten a bad rap for good reasons. Often, there are a lot of people - women, LBGT, and others - you know, hierarchical monotheism has been a real source of a type of oppression.

Every person with a pulse has a responsibility to stand in solidarity with the Muslim community that is on the front lines fighting against groups like ISIS, both militarily and ideologically, every day, and now on the front line of standing up for civil liberties and civil rights to make America great. [They] are the best insurance for the safety of all Americans.

Ordinary Americans can't pollute for free. You can't dump your trash on the sidewalk or throw all your refuse into your neighbor's yard. I don't understand why corporate polluters should be allowed to dump megatons of carbon, the most dangerous pollution in the history of the world, into our thin shell of an atmosphere, and not pay a penny to do it.

Little kids sing a song called "America the Beautiful." They sing a song called "This Land Is Your Land, This Land Is My Land." To me, those songs are not just nice little ditties. They are marching orders. They are commandments that we must protect America's beauty from the clear-cutters, the strip-miners, the oil spillers. They are pledges we have made. They are promises to keep.
