We rushed into renewable energy without any thought. The schemes are largely hopelessly inefficient and unpleasant. I personally can't stand windmill….

Climatologists are all agreed that we'd be lucky to see the end of this century without the world being a totally different place, and being 8 or 9 d….

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 tw….

I have a feeling that climate change may be an issue as severe as a war. It may be necessary to put democracy on hold for a while..

Ask almost anybody if they think the climate?s changed in the last couple of decades and they will all say ?yes? and give you lots of examples..

Geological change usually takes thousands of years to happen but we are seeing the climate changing not just in our lifetimes but also year by year..

China will soon emit more greenhouse gases than America, but its regime knows if it caps aspirations there will be a revolution..

Nowadays if you're dependent on a grant - and 99% of them are - you can't make mistakes as you won't get another one if you do..

There is little evidence that our individual intelligence has improved through recorded history..

Only nuclear power can now halt global warming..
