Stop using fossil fuels and food production plummets (random googled link which may or may not be accurate: http://www.fromthewilderness.com/free/ww3/100303_eating_oil.html). These problems are not simple.
And if anyone ever suggested that we "stop using fossil fuels" in anything less than a century and without some alternative, you could rightly dismiss them as a lunatic. No use of fossil fuels --> most of us die soon. This is why trying to figure out and respond to the consequences of fossil fuel use is crucial. The most radical alarmists have been trying to get is for us to stabilize our use of fossil fuels in the next few decades and invent alternatives as rapidly as possible. Reducing fossil fuel use is something to be looked at for 2050 and later. But any effort to argue even slowing down our use of fossil fuels is met simultaneously, in the US anyway, by earnest arguments that it is not that big a deal, that the science is uncertain, that the science is also certain that there isn't a problem, that every single possible move one could make is counterproductive, that absolutely no change is possible in future emissions, that money spent on innovation is wasted and shut up and go away. The trouble is, it was met with that in the 1970s and 1980s and 1990s as well as now. We lost at least four and maybe five presidential terms of useful small scale efforts, terms we spent subsidizing oil exploration instead of doing scientific research.
Indeed the problems are not simple, but your initial question was not should we stop using fossil fuels; it was is global warming a serious problem. Clearly it is. You've tried to cast doubt on many alarmist arguments and media hype, but said little about whether or not it is a serious problem. Look, if I suggested we make large scale changes to the world's economy because Ian Plimer was a dolt, I'd be wrong. By the same token, if some politician attributes Hurricane Sandy to climate change, or Al Gore says rhododendrons vent methane (he didn't) or some other nonsense comes out, it has no bearing on the seriousness of the problem. Do you believe that global warming is _not_ a serious problem? Is there a positive standard of proof climate scientists could meet that would justify in your mind even a modest policy response? Does the impossibility, in your mind, of ever modelling climate mean we can take no action, nor counsel any inaction, with any hope of a useful result? Is even Lomborg's recommendation outside the pale?
Last question: I gather you're in Germany. Do you think the weather there will be warmer in July than it is now?
