Great video guys. If I use your research in a debate, one of the obvious criticisms would be that you cherry-picked the locations that you analyzed. Were these the only 28 pairs that met your criteria? Using your same size criteria, have you done a more general analysis of all U.S. rural sites and all urban sites? That would be interesting.

We are trying to look at rural sites that have long histories at the moment (at least 150 that are at least 70 km away from urban sites. There may be an interesting effect of latitude on temperatures in the US. Some locations get warmer, some stay the same and some get colder. But there may be a pattern. There is also an issue with the cyclic nature of the rise and fall of the mean annual temp over the years. There appears to be about a 70 year cycle and it must be carefully considered .

BOTTOM LINE: to *ACCURATELY* determine long term climate(temp) change, URBAN SITES SHOULD NOT BE USED. IPCC denies a UHI *contamination* problem, but they are wrong.

NOAA is setting up a new U.S. Climate Reference Network for the express purpose of detecting the national signal of climate change.

Google USCRN, then look at the photos of ALL 120 stations. THEY ARE ALL RURAL! WHY? Because climate scientists KNOW that urban sites contaminate the data over time. Case closed.

Now, instead of the greenhouse, I build my house next to that station, surround it with blacktop, put my central AC unit right under it & build a big heavy brick bbq beside it. Over time, the other 5 temps stay constant but avg temp goes up because my *urban* station temp increased. Has climate changed on my sq mile of the globe? No. Is it proper to *homogenize* the stations and change temps of the other 5? No. The true measure of climate change would be found by eliminating my *urbanized* data.

Well done! I have been a major skeptic of "global warming" because the data sets include data from urban weather stations. There is an upward bias in the temperature at these stations due to urban heat island effect. Of course temperatures would appear to be climbing because urban areas are getting bigger. Not because of "global warming". No-brainer.

cool!

WHO'S PAYING YOU??? lol, sorry. I am getting paid by the cheesecake factory to ask that question.

Great Work - love the grass roots attitude and your display of scientific rigor that exceeds the rigor of the 'consensus'.

At 4:50 you say the average temperature of the rural sites surveyed is not increasing, please can you direct me to the supporting evidence in detail
