The presidency is more than a popularity contest.

I'm not trying to top anything. I'm trying to be useful, to play a positive role, to serve the public interest.

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.

There are skeptics who do not come to their view because they have a source of income from carbon polluters. I don't mean to imply that they're all in that category at all. There are also those who are also not motivated by ideological resistance for any role of government. But I don't know of any arguments or any presenters of arguments that overturn the consensus that I think have gained any legitimacy.

Mother Nature does not do bailouts.

The conversation on global warming has been stalled because a shrinking group of denialists fly into a rage when it's mentioned.

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.
