“The rural data set shows no warming since 1890! The temperatures have trended up and down, but there's no overall increase. The urban stations show a strong warming, especially after 1965. Are these two "skeleton sets" of raw data more representative of reality than the urban-polluted "adjusted" data sets in the official records? Long says "Yes"

* The raw data is that measured at the time, so, simply stated, those were the temperatures.

* The two sets had strikingly similar variations, with the rural set having more variability. The cities were warmer, but less susceptible to short-term changes in air temperatures due to their retained heat.

* The medium-term trends are similar up to about 1965, but the cities warmed much faster after that year. That's probably not global warming, but rather the in-filling of the cities: higher populations, more and taller office buildings, more streets and parking lots, more lost trees. The airports have poured more concrete, and become "development hot spots."

Both data sets show that public opinion has been heavily impacted by the continuing 30-year phases of the Pacific Decadal Oscillation. Temperatures rose strongly 1915–1940 during a Pacific warming, but World War II was scarier than any theory about man-made warming. When the PDO trended downward from 1940–1975, newsmagazines and "experts" predicted a new Ice Age. When the temperatures and the Pacific rose strongly again from 1976–98, the man-made warming scare was born and flourished. Now that earth has failed to warm for a decade, public fear of global warming has waned dramatically.

We have clearly been polluting the official temperature record with Urban Heat. Has none of the global warming scientists, cap and trade millionaires, and media folks noticed? Or have the billions and billions of dollars spent to "save the world from pending disaster" clouded their vision?”
