Temperatures Going Up?

If global warming is happening to the earth (i.e. globally), we should see a general increase in temperatures across the planet, right?

From CO2 Science:

This issue's temperature record of the week is from Dixon, IL. During the period of most significant greenhouse gas buildup over the past century, i.e., 1930 and onward, Dixon's mean annual temperature has cooled by 2.01 degrees Fahrenheit.

Not much global warming here!
