Not that the fools in Copenhagen care. If you can afford to not work and still travel to Copenhagen, you are probably not as worried about the price of food as the vast majority of humans are. The crowds in Copenhagen are a bunch of over propagandized rich kids who were easily bullied by their fad obsessed teachers into turning against the 'evil' capitalists. This, while they live lives built around the toys capitalists have no problem selling to them.
Also the data shows periods of much greater warming that could not have been man made and were not caused by increased CO2 levels.
