jim - // Perhaps, but doesn't that in itself undermine the point you're trying to make? Because it seems to me like you're saying that there *is* something humans can do to influence the future change of Earth's climate. In that case nature needn't "do what it does", and the only disagreement becomes the scale of changes in human activity necessary to achieve this. //
You advise that you know more about the science of climate change than most of us on here - I have no idea, I only have your word for it, and I don't really care either way.
What I think you need to accept is that human nature dictates that unless something is seriously impacting on the everyday lives of most people on the planet, they simply don't care what scientists are telling them about climate change, and that approach will continue until there are impacts on enough people for them to want to make a difference, and that is not going to happen in my lifetimes, or yours.
So, you can tell me that humans are 'destroying the planet', and I will say that while China is constructing coal-fired power stations at the rate of one a week, I am really not minded to care very much.
