Someone should tell the Gore-Bull Warmists that in micro-climate heating of cities filled with asphalt and cement absorbing large amounts of heat along with the direct heating of large building and homes causes large columns of rising hot air. This rising warmer air from large metro areas disrupts the jet-streams and has far far more of an effect on local and national weather than a few tenths of degrees here and there...

Yes, this is called the Urban Heat Island(UHI) effect and it is as you point out unrelated to CO2.

The temperature data set people claim that they calculate in some factor to supposedly cancel out UHI. Anybody what to bet that they don't do this correctly and that the results remain skewed on the high side.

Also when you have temperature stations that used to be on the outskirts of town that are now developed...

Gee this part of the city was developed 10 years ago and the air temps went up 10 years ago....

Golly, it must be CO2...

Most of their adjustments actually raise the recent temperatures and lower past temperatures. Because they have weird protocols about how the sensitivity of the instrument changed over time. The time of day the reading was taken. Etc. Etc. Basically progressive scientist are just like progressives. You cannot trust anything they say or do.
