Am I a denier? I really don’t think so. Who can deny that the climate is changing? What really sets us apart from the alarmists is that most of us know that most, if not all, of climate change is only natural variations. I started researching this a few years back because I wanted to know the truth. I did not have a particular truth that I was looking for, I just did not want to be lied to and I suspected I was. So I began researching the problem. I delayed launching into discussion about the politics as long as possible, simply because I did not understand enough of it to contribute to a discussion, though I had many questions.
We can all agree that there has been a net warming in the temperature trend at the rate of .6C per century. We can also agree that this has resulted in a reduction of the polar ice cap area at the rate of .02 per year and we can agree that there has been a sea level rise of about .17M per century. These three things seem consistent with a warming temperature trend. Fair enough.
However, what should be happening. Is a warming trend in the middle of an interglacial not to be expected. Why is this interglacial so much colder than the previous 4 interglacials. How much of this is natural and how much of this is man made, and how are we able to differentiate between the two. And what of the future? Will it continue to warm or will the interglacial finally come to an end and the long steady cooling period take over where the northern hemisphere will once again be blanketed by glaciers several kilometers thick?
Then there is the evidence. CO2 driven climate change should clearly show cause and affect. Monotonic growth in CO2 should be represented in the temperature record, but it is not. The temperature record is clearly showing cycles.
