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

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

NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station.

Evolution is a tightly coupled dance, with life and the material environment as partners. From the dance emerges the entity Gaia.

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.

Let's make hay while it lasts.

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.

Nature favors those organisms which leave the environment in better shape for their progeny to survive.

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.

Courage is feeling fear, not getting rid of fear, and taking action in the face of fear.

We can only see a short distance ahead, but we can see plenty there that needs to be done.

Man is obviously made for thinking. Therein lies all his dignity and his merit; and his whole duty is to think as he ought.

In the world of thought a man's rank is determined, not by his average work, but by his highest achievement.

I never left you; I never will leave you. While life lasts, and beyond, I am here.

As you submit to God more and more, you will get accustomed to being nourished by the power of truth. He is so holy that He cannot lie. God reveals His truth to His people through the Holy Spirit.
