The consensus is clear. We need an immediate and determined shift to a clean, renewable economy. The continued mass burning of fossil fuels is inconsistent with a healthy, prosperous future for our civilization.

Fake news has been around as long as news has been around.

You can say the Earth is flat, but it doesn't mean you're going to fall off the edge.

All I have to do is be the best Al I can be, because I'm good enough, I'm smart enough and, doggone it, people like me.

We need to put a price on carbon, and that's what cap-and-trade does and that's also what a CO2 tax does. As long as our current valuation in the marketplace tells us every minute of every day that it's perfectly all right to dump 90 million tons of global warming into the thin atmosphere surrounding the planet every 24 hours as if that atmosphere is an open sewer, then the individual actions are not going to solve the problem.

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.

Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.
