Earlier in this century, the Heisenberg Principle established that the very act of observing a natural phenomenon can change what is being observed. Although the initial theory was limited in practice to special cases in subatomic physics, the philosophical implications were and are staggering.

Having worked on climate crisis for almost 40 years now, I've seen good days and bad days. And through all of that time, the general trajectory has been it's getting worse, it's getting worse. But in the last ten to 20 years, there's a second development; the solutions are more and more, and more available. So having this broad overview that I've developed over a long period of time, I now see the evidence that the solutions are available. We're gonna do this.

We're all capable of mistakes, but I do not care to enlighten you on the mistakes we may or may not have made.

The wind and the sun are free.

It's a blessing to have work that feels fulfilling.

During my service in the United States Congress, I took the initiative in creating the Internet. I took the initiative in moving forward a whole range of initiatives that have proven to be important to our country's economic growth and environmental protection, improvements in our educational system.

I have felt for a long time that the pathway to solving the climate crisis is through the building of a massive grassroots army of men and women who will go out there and win the conversation on climate, and persuade businesses, and universities, and towns to switch to renewable energy and to reduce emissions. And the big change from ten years ago is that people are way more receptive, not only to the message that we have to act, not only to the message that now we can act, we have the solutions now - that's the biggest change - but also willing to make a commitment that we will act.
