Looking at the temperature over the last few years and saying look the earth is warming or the earth is cooling is like looking at the change in stock market with 1 minute worth of data and saying "see the stock market is increasing (or decreasing) this year" A single year is way to little data to determine what the overall trend is over 100, 1000, 10000, and especially 100,000 years. There is so much noise in these types of measurements that you can't with certainty say anything.

That is why for me the argument of global warming comes down to 1) is man kind changing the environment in a way that could have consequences. If the answer to that question is yes then the second question is 2) scientifically speaking how will those changes likely effect the earth.

The question should be "what are the likely effects of more CO2 in the atmosphere?" not "is the earth warming, cooling, or neither?"
