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.
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.
The entire range of living matter on Earth from whales to viruses and from oaks to algae could be regarded as constituting a single living entity capable of maintaining the Earth's atmosphere to suit its overall needs and endowed with faculties and powers far beyond those of its constituent parts.
Nature favors those organisms which leave the environment in better shape for their progeny to survive.
Evolution is a tightly coupled dance, with life and the material environment as partners. From the dance emerges the entity Gaia.
Humans are too stupid to prevent climate change from radically impacting on our lives over the coming decades.
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.
Climate change now represents so urgent a threat to mankind that the only way to deal with it is by suspending democracy.
Humans on the Earth behave in some ways like a pathogenic micro-organism, or like the cells of a tumor.
An inefficient virus kills its host. A clever virus stays with it.
I think that we reject the evidence that our world is changing because we are still, as that wonderfully wise biologist E. O. Wilson reminded us, tribal carnivores. We are programmed by our inheritance to see other living things as mainly something to eat, and we care more about our national tribe than anything else. We will even give our lives for it and are quite ready to kill other humans in the cruellest of ways for the good of our tribe. We still find alien the concept that we and the rest of life, from bacteria to whales, are parts of the much larger and diverse entity, the living Earth.
Those who fail to see that population growth and climate change are two sides of the same coin are either ignorant or hiding from the truth. These two huge environmental problems are inseparable and to discuss one while ignoring the other is irrational.
Sadly, it's much easier to create a desert than a forest.
Those of us who consider ourselves to be somehow involved in the birthing of a new age, should discover Gaia as well. The idea of Gaia may facilitate the task of converting destructive human activities to constructive and cooperative behavior. It is an idea which deeply startles us, and in the process, may help us as a species to make the necessary jump to planetary awareness.
By the end of this century, climate change will reduce the human population to a few breeding pairs surviving near the Arctic.
What we have lived through, the 20th century, has been like a great party. Adults now have had the best time humanity has ever had. Now the party is over and the Earth is reckoning up.
It just so happens that the green religion is now taking over from the Christian religion. I don't think people have noticed that, but it's got all the sort of terms that religions use. The greens use guilt. That just shows how religious greens are. You can't win people round by saying they are guilty for putting (carbon dioxide) in the air.
We need a more authoritative world...What's the alternative to democracy? There isn't one. But even the best democracies agree that when a major war approaches, democracy must be put on hold for the time being. I have a feeling that climate change may be an issue as severe as war. It may be necessary to put democracy on hold for a while.
Our future is like that of the passengers on a small pleasure boat sailing quietly above the Niagara Falls, not knowing that the engines are about to fail.
Life does more than adapt to the Earth. It changes the Earth to its own purposes.
So-called 'sustainable development' is meaningless drivel.
If we gave up eating beef we would have roughly 20 to 30 times more land for food than we have now.
There aren't just bad people that commit genocide; we are all capable of it. It's our evolutionary history.
One pound of uranium is worth about 3 million pounds worth of coal or oil.
Civilization in its present form hasn't got long.
