The truth about the climate crisis is still inconvenient to the large carbon polluters. And so they want to bob and weave and dodge the truth, and pretend like it's still a big controversy, and it's not. They want to pretend that this is up for debate. Like, whether or not the world is round is up for debate, or whether the moon landing really took place.

The age of printed pamphlets and political essays has long since been replaced by television, a distracting and absorbing medium which seems determined to entertain itself more than it informs and educates.

The constant drive for campaign dollars has distorted decision-making in Washington, DC, to the point where our systems can no longer effectively address complex, long-term problems like the climate crisis. Which brings me to my other major concern - the short-term focus of capitalism. It distorts the allocation of resources and the decision-making processes of companies.

I have a sense of mission on this climate crisis, and I'm trying to pour all the energy I have into it. And I hope that I, along with others, can catalyze the emergence of real solutions to the climate crisis. I think we're making a lot of progress. I think we're going to win this, but it matters how quickly we win it. So I'm focused on that.

There's a law of physics: For every action there's an equal and opposite reaction. And sometimes that shows up in politics and society. And I think that the reaction to President Trump's decision on the Paris Agreement has been much stronger than I had even hoped for. And the determination being expressed by so many people in state governments, city governments, in the business community, the investor community, is really heartening to me.

The more deeply I search for the roots of the global environmental crisis, the more I am convinced that it is an outer manifestation of an inner crisis that is, for lack of a better word, spiritual... what other word describes the collection of values and assumptions that determine our basic understanding of how we fit into the universe?

[T]he scientific enterprise will never be completely free of mistakes. What is important is that the overwhelming consensus on global warming remains unchanged.
