We are seeing every night on the television news now a nature hike through the Book of Revelation. These climate-related extreme weather events have convinced the vast majority of people that the scientists have been right for a long time. We have to address this.

Believe in the power of your own voice. The more noise you make, the more accountability you demand from your leaders, the more our world will change for the better.

Because these consequences are distributed globally, the problem masquerades as a distraction. Because the length of time between causes and consequences stretches out longer than we're used to dealing with, it gives us the illusion that we have the luxury of time. Neither of those things is true.

The United States has an absolute, uncompromising commitment to Israel's security and an absolute conviction that Israel alone must decide the steps necessary to ensure that security. That is Israel's prerogative. We accept that. We endorse that. Whatever Israel decides cannot, will not, will never, not ever, alter our fundamental commitment to her security.

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.

Any child born into the hugely consumptionist way of life so common in the industrial world will have an impact that is, on average, many times more destructive than that of a child born in the developing world.
