*sigh* - Show me some long term data, not cherry picked ranges. For example, when the five-year running average slopes down, it starts to become interesting. (the five year slope is pretty flat currently, so it could go either way next year)
Here's the same data source for 1979 through 2008. It's apparent that it has not been cooling for the last six years. At best you could claim 2 years, but that is not enough to claim a trend when you're talking about global climate.
Here's a comparison of satellite temperatures and direct surface measurements. All of the data agree that there is an overall warming trend, they merely disagree on the extent of the warming.
Let me be clear - I am not claiming that this is a doomsday scenario. My only point is that the data does not support the claim that we are in a cooling trend.
