As someone who believes that the global warming ‘problem’ is a case of peer pressure of many –and, yes, a great number of scientists — which man is prone to, and not a man-made problem, I still feel that I should give some thought to what might happen if I’m wrong and the IPCC warmists are right.
If the world’s governments continue to be largely ineffective in efforts to reduce carbon dioxide emissions — and it looks as though they’ll continue this way — then just how warm will the earth become? The forecasts of the IPCC have always been exaggerated since it made them 30 years ago when some, such as Al Gore, were actually implying that everything would be melting !. In its last trienniel Report the IPCC again softened down their previous forecasts by saying that if we did nothing then it would be nothing more than about 1.5 degrees centigrade and extremely uncomfortable and economically costly but manageable nonetheless.
It would have huge effects on the total ecology of the earth. Thousands more species would die — even more than the thousands that man has already extinguished with his industrial revolution. But this is nothing compared with the successive coolings and warmings that went on during and between all the previous Ice Ages. The earth’s ecology adjusted its composition each time with as many new species evolving as ‘uncomfortable’ ones vanished. And this sort of environmental flexibility will continue for billions of years yet.
What he concern of the IPCC and its followers really comes down to is that man can do almost whatever he likes to climate because we’re special. At its most extreme such a view is saying that it doesn’t really matter what happens to other species of flora and fauna so long as Homo sapiens survives. Science is telling us otherwise. We are increasingly learning that a rich interweaving tapestry of millions of species make for a healthier existence for all.
The earth, with a moderate stability of sunshine for billions of years yet could quite easily evolve other species which are as intelligent and virtuous (?) as man. In any case, the chances are high that we ourselves will bud further hominims able to live under the sea or hibernate in space while travelling to distant planets to colonise them. That’s when we can pick up the tag of being a ‘Special Species’, but not yet by a long chalk.
