I fully agree Paul. That is the key. I don't see any credible argument that global warming is not happening - the question is why. We could say that more 7 billion people, with their domestic animals (cows, sheep and goats) using ever more
oil, coal and cranking out pollutants gaseous and solid - has no effect at all. But that would be a short-lived fantasy land, from my reading on this.
So the next question is what can we do and this is where the politicians come in to it with 'solutions' that relate more to their policy positions rather than to the common good. I also agree with reasonably tight environmental regulation if we even want to retain much of what we have today, but like you I don't see a rosy future as long as India, China and others major contributors continue to produce ever more ...
(Note to self: never talk about politics, religion and now the environment!)
Heck I am off to drive the Cobra to work today while I can!
