Thank you Robert for your superb and balanced essay on the subject of climate change. I agree with the point you made about Africa, though its hard to watch. I understand the Sahara was once fertile plains.

I've copied this little bit of your post:

Neverthless it makes logical sense to me to go full out to find alternatives to fossil fuel now... since pumping anything even potentially harmful into the atmosphere when there is a credible alternative would not make sense. Motor companies should be morally persuaded to cease production of ridiculous sports cars and focus upon how society is going to get around in the future when the oil's gone. Population has soared to such an extent that any notion of returning to how we used to be pre-Industrial Revolution is frankly ludicrous, so unless a new source of energy can be discovered the future is bleak indeed, even with severe population growth restrictions. Guess we are looking for a new Einstein-calibre (or above) genius to get us out of this mess.

I fully realise that we cannot return to a 'horse power' society given the population explosion that's going on. One person restricting the use of their car is not going to make a difference is it, but that's where it starts. I read somewhere recently that many cities now have traffic free zones where people can just wander on foot - surely this is the way forward because whatever you believe about the causes of climate change, traffic pollution does have a serious impact on health.

On the political side of things, I have to wonder, along with many others, why the police spent millions on the under cover operation involving Mark Kennedy when all the Environmentalists were embarked on was peaceful protest. Unethical to say the least.

Thanks Tjj. I'm probably about as confused as anyone regarding where we are going as a species... and why we have such self-destructive tendencies. But our capacity to love - however uncomprehensive the results of that can be (tell me about it) suggests we will survive, adapt, no matter what. Unless the whole planet goes. That was on the cards during the Cold War, particularly when the H-bombs tests were underway. But luckily Sting was right... the Russians did love their children, too.

So let's hear it for love. And for those first Africans who decided to break-out to give their children a future all those millennia ago. If they had not would there be anyone in a position to help the decendants of those who chose to stay.... or were forced to say by climatic circumstances? The magnitude of such a decision is overwhelming. Whether our northern future is one of deserts of sand or ice is perhaps a question of degree. But, hey, we've been there before.
