The only thing that will really change global warming in the long run is if we radically increase the speed with which we get alternative technologies to deal with climate change.

We worry about the seemingly ever-increasing number of natural catastrophes. Yet this is mainly a consequence of CNN - we see many more, but the number is roughly constant, and we manage to deal much better with them over time. Globally, the death rate from catastrophes has dropped about fifty-fold over the past century.

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.

Wishful thinking is not sound public policy.

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.

For the longest time in Denmark I didn't want to say what I was politically. I thought it was irrelevant.

There is no question that global warming will have a significant impact on already existing problems such as malaria, malnutrition, and water shortages. But this doesn't mean the best way to solve them is to cut carbon emissions.
