NASA has a graphic which shows the global temperature deviations from seasonal averages for every month since 1979 through 2003. The most striking thing about the graphic is that although it seems like some places are consistently warmer than the seasonal average other places are consistently cooler. In other words, to the extent that warming is occuring it appears to be occuring locally or regionally and not uniformly around the globe.
Canada and the arctic seem to be warming while the southern states, Central, and South America seem to be cooling.
The bottom graph is the average global deviation from the long-term mean. You can select any month by moving the cursor across the graph. It appears that the average global temperature fluctuates around the mean spending as much time below it as above it (except for a bit of a spike in May of 1998).
So what's it all mean? I'm not sure, but it certainly suggests that the situation is more complex than the global warming people are letting on. The ambiguity of the data causes us to wonder what motivates those like The Weather Channel's Heidi Cullen who are so eager to have everyone believe that the earth is getting warmer that they want to forcibly silence all dissent from that opinion by having dissenters stripped of their scientific credentials.
