“I tentatively believe in a god. I was brought up in a fairly religious home. I think the world is compatible with reincarnation, karma, all that stuff.”

There is something wrong with saying we should start using renewables now, while they are still incredibly expensive.

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

The second thing is, if you want to do something about global warming, you have to think much more long-term.

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

We worry about the seemingly ever-increasing number of natural catastrophes. Yet this is mainly a consequence of CNN.

I found university a little dispiriting. I thought I would enter the great halls of Plato, but instead I entered the halls of an intellectual sausage factory. I wanted to do something not on the main course, and chose the environment.

Across Europe, there are six times more cold-related deaths than heat-related deaths…by 2050…Warmer temperatures will save 1.4 million lives each year.

Of course, the world is full of problems. But on the other hand it’s important to get the sense… are we generally moving in the right direction or the wrong direction?

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.

To prepare adequately for the challenge of global warming, we must acknowledge both the good and the bad that it will bring.

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.

Surely the biggest problem we have in the world is that we all die. But we don’t have a technology to solve that, right? So the point is not to prioritize problems; the point is to prioritize solutions to problems.

So it’s mainly a question of helping the Third World overcome the effects of global warming.

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.

Nobody wanted to buy a computer in 1950, but once they got cheap, everyone bought them.

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.

Christianity had the great religious wars of the 17th century. Islam, fortunately for the Muslims, did not have that. Christianity worked out a system of toleration. Islam was always more tolerant of Christendom.

Refugees of all kinds were constantly fleeing from Christendom to the Islamic lands. Jews of course and Muslims of course, but even some Christians and the movement of refugees went overwhelmingly that way.

Mohammad founded a state which soon became an empire, so that Islam from the very beginning is involved with government, with politics. And therefore there is a very clear strong political tradition in Islam.

Muslims have their own tradition on limited government. Now in Islam, there is a very strong political tradition. Because the different circumstances, Islam is political from the very beginning.

For strictly scientific or technological purposes all this is irrelevant. On a pragmatic view, as on a religious view, theory and concepts are held in faith.

When we talk about the Judeo-Christian or the Judeo-Muslim tradition, it’s important to remember that we are speaking of a Jewish component of civilization, but not in itself a civilization.

Political dictatorship and social hopelessness create the desperation that fuels religious extremism.

The Constitution of the Republic should make a Special privilege for medical freedoms as well as religious freedom.
