If a power station were to be built down the road, I'd prefer a nuclear plant over an oil burner, and definitely over a coal burner. We simply have to lessen our consumption of fossil fuels.

Humans are too stupid to prevent climate change from radically impacting on our lives over the coming decades.

There aren't just bad people that commit genocide; we are all capable of it. It's our evolutionary history.

The problem is we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books - mine included - because it looked clear-cut, but it hasn't happened.

There is no clear distinction anywhere on the Earth's surface between living and nonliving matter. There is merely a hierarchy of intensity going from the 'material' environment of the rocks and the atmosphere to the living cells.

All the modelling we do shows that the climate is poised on the jump up to a new hot state. It is accelerating so fast that you could say that we are already in it.

Civilization in its present form hasn't got long.
