Satellites vs. thermometers

Phil Plait, the Bad Astronomer, has a pretty good post up about measuring global temperature the satellite way and the thermometer way.

Global Warming, Satellites vs. Thermometers

It features the Yale Climate Connections video, which is good, too.

I like the contrast he draws between Ted Cruz and Lamar Smith.   Smith thinks it bad to "alter" data, which is his word demonstrating he doesn't understand the meaning of calibration and bias reduction.  And it's also pointed out that satellite data, which Cruz was claiming was the best we have and doesn't show global warming (which ain't true any more), is adjusted more than surface thermometer data.  So it's bad according to the Smith criterion.

So ultimately, everything is showing its getting warmer.  Unless you're a true denier, in which case nothing will.
