Seeing as comments have been made I've got a question.
Well,... actually first I'd better point out that I'm a fence sitter on this issue but that I lean towards the global warming believers side. I think even if it's a myth it can't hurt for us to take better care of our planet and make an effort to curb pollution, regardless if it's causing warming or not as we are certainly doing a great job of wiping out whole species. People who are sceptical and believe that this gives them the right to be ignorant and knowingly pollute should go find another planet. All you city 'bus-sized' SUV driving numpties I'm looking at you

.. jokes aside here's my question:
I'm intrigued why so many convinced sceptics believe it's a scam by governments. Surely capatalist governments would be on the sceptics side as the biggest pressure groups are all large industry, oil, transport, manufacturing etc. and doing something about global warming means diverting tax dollars and greatly upsetting large industry. If you don't have these guys on your side then kiss the next election goodbye. So why do the sceptics use the scam argument? I can't think of a single large company that wouldn't be affected by measures used to ensure that carbon emissions are lower.
I can understand an ulterior motive for alternative fuel companies and other companies that are marketing greener products, but these companies are tiny compared to global oil, car and manufacturing giants who have economies bigger than small countries.
Ok I can understand that governments might have been misinformed but why would they knowingly buy into a scam, how would they profit from that?
P.S won't energy conscious societies do wonders for light pollution?
