Many cannot agree upon a few ideals. But few disagree with one scientific break through. Carbon dating.
Analytically speaking, if exhibit A is carbon dated to an era before man, then how does it arrive back to man? Have we disregarded plate tectonics in our search for global warming?
What about continental drift, as presented by the German geophysicist, Alfred Wegener, from his model called "Pangaea"? Furthermore, by following his hypothesis is not clear that South East Georgia, and North East Florida is in fact changing to match from it's jigsaw cut? Recall that this region was attached to Africa in the area of modern day Morocco and Western Sahara, which are home to the Sahara desert. IIRC, both of these areas have seen mass drought, deforestation from dry conditions and increased wildfire over the last several years.
Moreover, I feel the human effect has placed a demand on the total climate that may or may not be changeable in the foreseeable future. What I do have an interest in, and follow closely is what the Greeks are reporting about deterioration of their ancient historical relics. It appears that scientists over the years have recorded deterioration levels and have made some hypothesis that an increase can be traced to a significant event. The automobile, and man made pollutants. One such hypothesis is that over the last 50-60 years, the measurable increase of carbon dioxide has propelled the deterioration process into previously unrecorded stages. To me, this places man at the center of cause, and the effect is a change of climate that has only been rarely recorded in history. All of which is based upon, carbon dating.
I theorize that Al Gore is making bank on scare tactics and is selling a future called carbon credits that allow some to feel at ease because he received an award about publicizing previously documented historical research that many already are aware of. In fact, many movies of recent blockbuster status feature this phenomenon, could it be, we are headed into a historically documented but unpredictable change to the physical environment that many know as, an "Ice Age"?
