Now we have things that are obviously false, leading us to war, leading us to deny people health care, leading us to ignore the climate crisis. We have to restore the integrity of the democratic conversation.

Although I have a variety of obligations, the climate crisis is my central concern.

George W. Bush promised us a foreign policy with humility. Instead, he has brought us humiliation in the eyes of the world. He promised to restore honor and integrity to the White House. Instead, he has brought deep dishonor to our country and built a durable reputation as the most dishonest president since Richard M. Nixon.

The physical relationship between CO2 molecules and the atmosphere and the trapping of heat is as well-established as gravity, for God's sakes. It's not some mystery.

The truth about the climate crisis is still inconvenient for the large carbon polluters and the politicians who are in their pockets.

The Himalayan Glaciers on the Tibetan Plateau have been among the most affected by global warming. The Himalayas...provide more than half of the drinking water for 40% of the world's population...Within the next half-century, that 40% of the world's people may well face a very serious drinking water shortage, unless the world acts boldly and quickly to mitigate global warming.

...it is appropriate to have an over representation of factual presentations on how dangerous it is, as a predicate for opening up the audience to listen to what the solutions are, and how hopeful it is that we are going to solve this crisis.
