Global warming my arse

the-smiling-buddha But climate change, caused by humanity's tipping the balance of CO2, is a scientifically proven fact

Actually I believe that it is a consensus of opinion and not a scientificaly proven fact. Unless of course you can tell me how it was proven, by whom and when.

What's the IPCC, if not peer reviewers of scientific propositions?

Just a bunch of circus entertainers? Star Trek fans?

You might be confusing the use of consensus to take decisions with a lack of rigour. Consensus is much more rigourous, and demanding, than simply voting. It's actually a very good way of establishing scienctific facts. Another thing you ought to educate yourself about.
