There are many who would much prefer that the word 'climate' never be mentioned and that the issue be eliminated from our national conversation.

...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.

I would distinguish between Donald Trump and the United States of America. Although he is president, he does not speak for the country on the climate change, and that was vividly illustrated in the aftermath of his speech pulling the US out of the Paris Agreement. Almost immediately, not only did the rest of the world double down on its commitments, but also here in this country, governors, mayors, business leaders, they said, we're still in the Paris Agreement, and they're doubling down. A lot of cities have now made a decision to go 100% renewable energy.

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.

I am a passionate advocate of getting special interest money out of politics.

If you look at the way all of the new reform movements dedicated to the public interest are living and thriving on the Internet, I do think there is still some considerable hope that the full participation of individuals in that conversation of democracy can once again restore the integrity of the way our democracy works.

I take no pleasure in the fact that the scientific predictions I’ve relayed to popular audiences turn out to be true.
