My suggestion is that we should first work to ensure the Third World has clean drinking water and sanitation.

The obvious issue is providing clean drinking water and sanitation to every single human being on earth at the cost of little more than one year of the Kyoto treaty.

The Kyoto treaty has an estimated cost of between US$150 and $350 billion a year, starting in 2010.

Wishful thinking is not sound public policy.

We need to invest dramatically in green energy, making solar panels so cheap that everybody wants them. Nobody wanted to buy a computer in 1950, but once they got cheap, everyone bought them.

Money spent on carbon cuts is money we can't use for effective investments in food aid, micronutrients, HIV/AIDS prevention, health and education infrastructure, and clean water and sanitation.

On average, global warming is not going to harm the developing world.

The fact that we're catching more fish per person than we've ever done before doesn't mean that there are not particular places where we've managed fisheries badly.

Global warming is real - it is man-made and it is an important problem. But it is not the end of the world.

Think on a 50-year scale, which is a much more natural time-scale for global warming. The US is right now spending about 200 million dollars annually on research into renewable energy.

Obviously any group that has to have funding also needs to get attention to their issues.

Think of me as an impetuous Hegel, drunk with power, and also, regular drunk.

Sometimes another person’s fear tells you that everything you're about to do is right.

I know where nowhere is, I know where nowhere leads, it's the place you go when you have nothing left to lose but you.

To unlock the writer's block is to keep writing until you can unknot the "not". If you cannot, then put a can in the plot and unwrap it a lot!

He who know most grieves most for wasted time.

Although I enjoy digging through the library to help students find books, my aim is to help them develop self-confidence in choosing books for themselves.

You speak what you believe, and you believe you’re doomed. If there’s one thing I’ve learned throughout the years, it’s that what you believe is the impetus for your entire life.

I often thought my gravestone would say, 'Here lies Gandalf. He came out,'

Good teachers deserve apples; great teachers deserve chocolate. A favorite quotation, written in calligraphy on his office door.

What we'd like to think of YouTube as is a part of Google with very overlapping goals and values. We're a fundamental part of the advertising business for Google.
