Satellite temperature measurements have consistently shown the total temperature rise for the last galf of the 20th century was only .1 degrees F.

Curious points: one, the satellite temps start in 1979, so they don't cover the last "half" of the century; two, the minimum trend of three separate analyses is now about 0.13 C per decade (the other analyses are at about 0.2 C per decade); three, the 0.36 F figure is for the surface, and the satellites measure the temperature of the lower troposphere (and also the middle, troposphere+mesosphere, and also the stratosphere).

the 0.36 F figure is for the surface, and the satellites measure the temperature of the lower troposphere (and also the middle, troposphere+mesosphere, and also the stratosphere).

I would ask the question how much of that 0.36 F figure takes into account the "heat island" effect from the massive metropolitan areas represented by the likes of major cities such as LA, Houston, Chicago, NY, Tokyo, the Dallas-Ft.Worth area, etc.? These massive urban developments are known to retain heat longer and have affected weather patterns as a result of that factor.

I watched a snowstorm advancing on Ft. Worth a few years ago and expected that we would be hit by a rare snowstorm. However, as the storm approached the outskirts of the Dallas-Ft. Worth metropolitan area, the heat island affect caused the storm to literally split and bypass the area. Later, I received a call from my sister in San Antonio (which got 3 inches from this storm) asking how much snow we received. She was astonished when I told her it went around us.
