There is basically no one not on the payroll of Exxon Mobil or coal companies who any longer contend that this is not something to worry about.

So far the earth has warmed about a degree Fahrenheit globally averaged. That doesn't seem like an enormous amount but it's unlike what we would have expected twenty years ago.

we use TV as we use tranquilizers- to even things out, to blot out unpleasantness, to dilute confusion, distress, unhappiness, loneliness.

You think OWS is radical? You think 350.org was radical for helping organize mass civil disobedience in D.C. in August against the Keystone Pipeline? We're not radical. Radicals work for oil companies. The CEO of Exxon gets up every morning and goes to work changing the chemical composition of the atmosphere. No one has ever done anything as radical as that, not in all of human history.

To me, it's more important to take the 60-70% of people who really understand that there's a problem [of climate change] and get some percentage of them active than to try and stamp out the last embers of pre-scientific thought.

One of my favorite places is the Maldives, an all-Muslim nation in the Indian Ocean with a culture that stretches back 5,000 years. But since the highest point in the archipelago is a meter or two above sea level, even the next hundred are not guaranteed. They've committed to becoming the first carbon-neutral nation on Earth by 2020, building windmills as fast as they can.

In the end, climate change is a math problem.
