I do genuinely believe that the political system is not linear. When it reaches a tipping point fashioned by a critical mass of opinion, the slow pace of change we're used to will no longer be the norm. I see a lot of signs every day that we're moving closer and closer to that tipping point.

We have arrived at a moment of decision. Our home - Earth - is in grave danger. What is at risk of being destroyed is not the planet itself, of course, but the conditions that have made it hospitable for human beings.

We face a climate crisis now that is the most serious challenge our civilization has ever confronted. And the greatest country in the world [America] has to remain a part of this unprecedented global agreement to deal with it.

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.
