What we take for granted might not be here for our children.

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.

American democracy is in grave danger from the changes in the environment in which ideas either live and spread or wither and die.

Atheists have just as much of a right to the public discourse as any ... people of any religious faith in this country.

If youre a young person looking at the future of this planet and looking at what is being done right now, and not done, I believe we have reached the stage where it is time for civil disobedience to prevent the construction of new coal plants that do not have carbon capture and sequestration.

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

I'm not a psychologist, and I don't know how to play a more sophisticated role than the one that I have played for quite a few years, and that is spending a lot of time with these hard-working scientists in the various fields of expertise that relate to the climate crisis, learning as fully as I can the truths they are discovering, asking them to explain it in language that's simple enough for me to understand and then use that language to convey the essence of it, and then letting the chips fall where they may.
