There's lots about politics I don't feel comfortable with. To talk about the politics of future ideas is impossible in soundbite form.

It's an important point, and every little bit helps not least because those who make those kinds of changes are more likely to make their voices heard as citizens. But the ultimate solutions are going to come through policies.

The debate's over. The people who dispute the international consensus on global warming are in the same category now with the people who think the moon landing was staged on a movie lot in Arizona.

...the debate among the scientists if over. There is no more debate. We face a planetary emergency. There is no more scientific debate among serious people who've looked at the science...Well, I guess in some quarters, there's still a debate over whether the moon landing was staged in a movie lot in Arizona, or whether the Earth is flat instead of round.

America's political system has evolved over the last 50 years in ways that have enhanced the power of business lobbies.

Take it from me - every vote counts. In our Democracy, every vote has power. And never forget - that power is yours. Don't let anyone take it away or talk you into throwing it away. And let's make sure that this time every vote is counted.

I have a personal staff that helps me scour the internet and other media for the latest scientific peer-reviewed findings, the latest examples of climate-related extreme weather events, and the latest examples of progress. The world is in the midst of a sustainability revolution that has the scope of the industrial revolution, but with the speed of the digital revolution. That's not enough without new laws and the right kind of political leadership. But it does give us a base from which to build a movement that will save us from the most catastrophic consequences of the climate crisis.
