Warming Yes, C02 maybe (Score 1)

I am not a environmental scientist. However I am an expert at statistical analysis. (An expert statistical analyzer?) There is absolutely no question that the earth's core temperature is rising abnormally. However it is not entirely clear whether or not C02 is the prime culprit. At this point it is the best guess. As I'm sure all of you know, the scientific method requires laborious testing in closed conditions with isolated variables. In the best conditions an experiment can be run multiple times (often times in the 1000's). This allows for a large pool of data reducing the general variable error rates. Basically, if you flip a coin 4 times and record the results, you are more likely to see data sets of all heads or all tails. This might lead one to believe that one side is more likely to be flipped than another. However flip the coin 1000 times, you are more likely to get something close to a 50/50 split. Scientists are dealing with 1 earth. At best they have 3 examples to compare (Earth, Venus which has a dense C02 atmosphere, Mars) Point being, its clear that global warming is happening, its hard to be sure that C02 is the single most influential cause. Honestly I am very concerned that global warming has more than just a single cause. We are so eager for a simple, "single shot" answer in general these days... Outside of carbon dioxide emissions, I would like to see more done to combat the heat island effect (http://en.wikipedia.org/wiki/Heat_island/) which may or may not be contributing to global warming.
