When people flirt with despair about the future, they are less likely to take the actions necessary to safeguard it, focusing instead on the short-term.

At some point, a false belief collides with physical reality.

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

There are people who say, "God is in complete control of everything that happens, and if the Earth is getting warmer, then maybe God intends that." Well, no. God intends for us to take responsibility for how we treat God's creation, and if we choose to use the thin shell of atmosphere surrounding our planet as an open sewer for 110-million tons of global-warming pollution every day, the consequences are attributable to us. And if you are a believer, as I am, I think God intends for us to open our eyes and take responsibility for the moral consequences of our actions.

When energy prices go up, the difficulty of projecting demand also goes up - uncertainty goes up.

What we've often seen is that when we Americans say, look, we've got to reduce pollution, business - some businesses complain about it, but almost every time, it's turned out to be easier and cheaper and accomplished faster, and they've gained confidence, and then we go farther.

A leapord never changes his stripes.
