This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model, for the first time in human history.

We are just about to cross the 400 parts per million threshold.

We have to get to the point where each individual, each corporation, each community chooses low carbon, because it makes fundamental sense. It should become a no-brainer.

We shouldn't have stupid cars that use liquid fossil fuels. Come on, how outmoded is that? We have to get to the point where this is no longer a part of our experience.

You can rear children in an antagonistic environment or in a facilitative one with a good combination of love and discipline. It's about supporting them, and recognizing achievements and contributions, but also saying, "that's fantastic but it's not enough, here's the next thing."

The U.S. military is investing in new storage technology because most of the weight that soldiers carry on their backs is batteries. Once that gets developed for the military, it will be expanded to civilians.

We have already used more than half of that budget. This means that three quarters of the fossil fuel reserves need to stay in the ground, and the fossil fuels we do use must be utilized sparingly and responsibly.
