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.

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.

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

Wishful thinking is not sound public policy.

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.

We create ourselves endlessly.

I can't think of anything worse than trying to schmooze someone with the idea that you're an actor.

You need to suffer to be interesting.

If the Wright brother were alive today Wilbur would have to fire Orville to reduce costs.

If we're going to talk about mayors, that under the current mayor [of New York in 2016], crime has continued to drop, including murders.

I love my career right now, and I won't be with anybody until they make my life as satisfying and as happy as my work makes me.

Let my thoughts come to you, when I am gone, like the afterglow of sunset at the margin of starry silence.

When I'm ninety-five and it's 'This is Your Life' time, they'll still be referring to me as 'ex-Beatle'...it does have it's advantages. It's still the best way to get a good table at a resturant.

It is unfair to label me anti-Islam. I am an atheist and a secular humanist.

I am quite sensitive to politics, because you know, as an Arab, an Iraqi, all your life, you are very conscious of it.
