The good news is, we have everything we need now to respond to the challenge of global warming. We have all the technologies we need, more are being developed.... But we should not wait, we cannot wait, we must not wait.

You know, 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." I think that's happening.

We have to use our reasoning capacity and set long-term goals based on our deepest values.

I'm going to be focused on doing everything I possibly can to help solve the climate crisis.

The climate, financial and national security crises are all connected. They share the same cause: Our [the USA's] absurd dependency on foreign oil. As long as we need to spend billions of dollars each year to buy foreign oil from state-run oil companies in the Persian Gulf, our problems of a trade deficit, a budget deficit and a climate crisis will persist.

The mountain glaciers in every region of the world are melting, many of them at an accelerated rate, threatening drinking supplies - drinking water supplies and agricultural water supplies. We have these record storms, drought, floods, fires, three deaths (ph) in the American West, climate refugees beginning now, expected to rise to the hundreds of millions unless we take action.

We need to remake the Democratic party. We need to remake America.
