^ Ah mate - I know that the world is being poisoned, but I know that Viking settlements were growing crops on greenland during the last time the earth warmed up.

All this Climate Rage has come from the Club of Rome, of which Al Gore is a member, about which even Wiki says;

According to this book, divided nations require common enemies to unite them, "either a real one or else one invented for the purpose."[6] Because of the sudden absence of traditional enemies, "new enemies must be identified."[6] "In searching for a new enemy to unite us, we came up with the idea that pollution, the threat of global warming, water shortages, famine and the like would fit the bill."
It's all a con. It's fake. The world get's hotter and colder. It's what happens. Climate change is WMD. It is Al Qa'ida. It is the Banks failing that need cash. It is the big bogey man in the cupboard. It is simply another fear tactic.

Just ask one question. After WW2 when there was so much industrialisation, and so much damage done to the world, why did the temp drop for 30 years? That was the peak time when every nasty chemical and process in the world was being spewed into the air and dumped all over the place and yet year after year temps dropped. Then in the 1970's the temp went up a little. Then the last 12 years it has stopped.

It's all a pile of shit. Pollution is not good but it has nothing to do with climate change.
