I drive a hybrid. Tipper and I got a Lexus hybrid. And we have a couple of Priuses in the family with our children. And I encourage people to make environmentally conscious choices because we all have to solve this climate crisis.

Capitalism is the best way of organizing economic activity for a lot of reasons. It unlocks a higher fraction of human potential, it balances supply and demand, it's more consistent with higher levels of freedom. But the way we're pursuing it now, focuses on such short-term horizons, that a lot of businesses and investors are tempted to look at investments in terms of what's gonna happen in the next 90 days, what's gonna happen in one year. But the old phrase, "Good things take time," is true of successful businesses as well.

For me, the most serious problem is how America became so vulnerable to the assertion of blatant falsehoods that drive policy and are not corrected by the so-called immune system of democracy, a free press and a free democratic discourse.

Well-established theories collapse under the weight of new facts and observations which cannot be explained, and then accumulate to the point where the once useful theory is clearly obsolete.

The struggle to save the global environment is in one way much more difficult than the struggle to vanquish Hitler, for this time the war is with ourselves. We are the enemy, just as we have only ourselves as allies.

In physics there's the old law for every action there's a equal amount of reaction. Sometimes that's true in politics. If somebody's out there making nonsensical statements, but wielding power behind them a lot of people say, "Well, I need to react to that." Another reason for the increased prominence of the climate-change issue is the Paris Agreement itself. It's not a small thing when just about every nation in the entire world comes together and makes an historic agreement like this. It's a big deal. And the old cliché "The train is leaving the station" kind of applies.

In an economic recession, naturally, when you ask people to list their priorities, they're going to place a higher priority on the immediate economic situation.
