Okay, my position is that there is no way that the human activities have no measureable effect on climate. That is subtle, but you still have people debating it.
We are not moving away from the sun BTW, and the last warm years and their temp records were set during a solar minimum. How's that?
An excellent question. If I understand the theory correctly, the reason for that is that the solar miminum equates to reduced solar wind and weaker magnetic flux. This in turn allows more cosmic rays and particles to reach the Earth, affecting cloud formation and resulting in increasing temperatures. It is perhaps no coincidence then that global temperatures have stabilized as solar activity is reversing its trend. According to the theory, temperatures should begin to go down now.
I do not deny that global temperatures fluxuate; the Earth's geological history tells a story of alternating warm and cold periods for eons. I simply believe the science does not support CO2 as a driving factor. CO2 is a minor component of the so called "greenhouse gasses". Further, there is evidence to suggest that it is a result of global temperature increases, rather than the cause. Finally, what impact CO2 has in trapping heat falls off as an exponential decay, meaning that doubling the amount has X effect, doubling it again has 1/X^squared, and so on. For this and many other scientific and technical reasons I've read, I believe CO2 to be inconsequential as a driver of global temperatures.
As for money, much more has been spent trying to prove man-made GW than the oil and energy companies have spent trying to disprove it. The science is anything but settled, and more and more scientists have come to the conclusion that MMGW is a sham.
