My question for the greens is, do you have a PhD in Meteorology, 50 years experience as a research meteorologist, and have you headed up a major NOAA research institute? I bet the answer is no. Well, I don't have these qualifications either, but my late father did. When he read Al Gore's book (about a month after it was published), his comment was, "I have never before seen so much bad science, so much good science misapplied and so many outright errors in one publication in my entire life." He went on to explain that the temperature cycle (pick your starting point, warmest or coldest) is, on the average, 1500 years long, and this cycle has been going on for many tens of thousands of years. Once meteorologists, astronomers and geologists put all this together, they went looking for a reason and discovered a parallel cycle, also with an average length of 1500 years, that is the amount and intensity of sunspots and solar flares on our own sun, and is the overall driver of the temperature cycle. When I asked if CO2 content in the atmosphere could make any significant difference, he answered that it is not impossible that it could make a difference of as much as 1% or 2% in our temperature, but that the sun spot cycle was was and will remain the driver. We don't need to be making extreme financial efforts to reduce CO2, we need to be preparing for the inevitable as this warming portion of the cycle continues, because nothing we do about greenhouse gasses is going to make a difference in the inevitable weather actions that occur until it starts back into the cooling portion of the cycle. Of course, like a dummy, I didn't ask him approximately where we are in the current warming portion of the cycle.
