We are in a fool's climate, accidentally kept cool by smoke, and before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable.

I wouldn't be against them (large wind turbines) if they actually worked.

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

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.

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.

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.
