We ought to approach this challenge [of global warming] with a sense of profound joy and gratitude: that we are the generation about which, a thousand years from now, philharmonic orchestras and poets and singers will celebrate by saying, they were the ones that found it within themselves to solve this crisis and lay the basis for a bright and optimistic human future.

I think the fact that within the bitcoin universe an algorithm replaces the functions of the government is actually pretty cool. I am a big fan of bitcoin.

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.

When it comes to climate, we can all make a big difference.

The misconception that there is serious disagreement among scientists about global warming is actually an illusion that has been deliberately fostered by a relatively small but extremely well-funded cadre of special interests, including Exxon Mobil and a few other oil, coal, and utilities companies. These companies want to prevent any new policies that would interfere with their current business plans that rely on the massive unrestrained dumping of global warming pollution into the Earth's atmosphere every hour of every day.

I remain optimistic that ultimately free speech and a free press where individuals have access to the dialogue will have a self-correcting quality.

If the people that believed the moon landing was staged on a movie lot had access to unlimited money from large carbon polluters or some other special interest who wanted to confuse people into thinking that the moon landing didn't take place, I'm sure we'd have a robust debate about it right now.
