Here's an interesting article that does seem to take a more reasoned approach; it criticizes the way in which the media talk about climate change, but also admits there is a problem that needs to be addressed and offers up some scenarios and numbers.
The IPCC reports frequently contradict alarmist rhetoric but I point that out I often get some yahoo whinging about how I am ignoring the "97% consensus".
The article essentially makes my point that natural evolution of tech and society will "fix" the problem without any need for radical interventions by government - just like what happened with the over population/resource depletion panics in the 70s.
