Weather Channel founder calls Global Warming "a scam."

Hi guys. If I may jump into the conversation late here ...I think I would agree with Legend that global warming models have not made many specific predictions that have been verified. Similarly they have not made many specific predictions that have been falsified. Accurate computer models have not been available until recently, and if you make a prediction about what temperature, clouds, CO2 concentrations, etc, will be like ten years from now, you have to wait ten years to see if you are right. This is not a fault of the models, it is a fact of life.That said, it is clear that the warming recently has been very significant, and it is beyond the norm of common natural climate fluctuations. I am not familiar with most of the techniques that are used to reconstruct past temperatures, but here's an easily understood piece of evidence. Plant material that this glacier left behind as it melted was carbon dated to be ~50,000 years old. So over the last 50,000 years the weather was not warm enough to melt this ice until recently.So yes, there are natural variations in the climate, and in the distant past it was warmer than it is today. But climate fluctuations of this magnitude are rare on the time scale of recorded human civilization, and the probability that such a fluctuation just happens to be occuring naturally at the same time as we are pumping vast amounts of heat trapping gasses into the atmosphere seems extremely unlikely. So humans are almost certainly the primary cause of the warming.That's how it seems to me, anyway, though I'm no expert.
