The world has not warmed up very much since the millennium.

I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.

The big threat to the planet is people: there are too many, doing too well economically and burning too much oil.

The oil companies regard nuclear power as their rival, who will reduce their profits, so they put out a lot of disinformation about nuclear power.

The inertia of humans is so huge that you can't really do anything meaningful.

One thing that being a scientist has taught me is that you can never be certain about anything. You never know the truth. You can only approach it and hope to get a bit nearer to it each time. You iterate towards the truth. You don't know it.

Perhaps the single most important thing that we can do to undo the harm we have done is to fix firmly in our minds the thought: the earth is alive.
