Actually I think that the debate on climate destabilization is largely over since Hurricane Sandy occurred right over the capitalist decision-making centers of the east coast. This disastrous storm could not have hit a better place in terms of influencing the debate. Now our masters who are (literally) addicted to the wealth and power "highs" delivered by capitalism, the root cause of environmental degradation, are using their media to censor out any relationship between climate disasters that are becoming increasingly evident and global warming; and when they do mention the latter, they emphasize fantasies about technology solving the problem.
If people are just confused about climate, they can be reasoned with. The facts are convincing, to anyone who is willing to see. But nothing convinces hard core science deniers, as this 2009 episode from Wiley Miller‘s comic strip Non Sequitur illustrates.
