I really try to say things as they basically are and it so happens that it is a good message that things are getting better, but there are still problems.

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.

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.

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.

It doesn’t matter. I love you. That’s it. That’s all. I hope to hell it’s enough.

If you keep wandering in the dark streets, may be it is because you find peace in the darkness rather than in the light!

The instinct to tell our children that they are better than someone else’s children, based on nothing more than the color of their skin, is now a fossilized aberration that serves no useful purpose.

[A]s military history reveals, a bad plan is often better than no plan, especially if the people on the other side think it’s a good plan.

Vampire Willow Rosenberg: "In my world, we have people in chains, and we can ride them like ponies.

No matter how lofty you are in your department the responsibility for what your lowliest assistant is doing is yours.

I'm perfectly miserable; but if you consider me presentable, I die happy.

There is an Arabic writer who wrote philosophy and poetry and who brought all religions and all the world together.

Medicine is only palliative. For behind disease lies the cause and this cause NO DRUG can reach.
