A Different Perspective of Global Warming

Let’s take a different look at AGW….

Bob Tisdale - Climate Observations

I was preparing a few graphs for a chapter of my upcoming book (current working title An Illustrated Guide to Global Warming and Skepticism), and I thought readers here would find them interesting because they display global warming in a different light.  The changes in temperature are minuscule when we look at the annual temperatures at all latitudes of the planet. I believe most of us are aware of that fact, and often times, because we’re looking at anomalies, we lose sight of the big picture.  (Those warming signals would be even smaller if we were to consider the seasonal cycles and daily variations in temperatures…but those additional variations are beyond the scope of this post.)

In this post, we’re going to be looking at global temperature data and a reanalysis of global temperatures in absolute form, on a latitude-average (zonal-mean) basis, for two decade-long periods:  1979 to 1988 and 2003…
