Listen, global warming is a real problem, but it's not the end of the world. A 30-centimetre sea level rise is just not going to bring the world to a standstill, just like it didn't over the last 150 years.

...children born today-in both the industrialized world and developing countries-will live longer and be healthier, they will get more food, a better education, a higher standard of living, more leisure time and far more possibilities-without the global environment being destroyed.

Im no expert on American politics.

The second thing is, if you want to do something about global warming, you have to think much more long-term. There is something wrong with saying we should start using renewables now, while they are still incredibly expensive.

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

I think it's great that we have organisations like Greenpeace. In a pluralistic society, we want to have people who point out all the problems that the Earth could encounter. But we need to understand that they are not presenting a full and rounded view.

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.
