2012 was the warmest year ever for the U.S.

Compared to what? Given the earth is hundreds of years old, don't you think it is a tad but presumptuous to think we can control the weather?

Presumptuous is a big word for an inbred redneck freak.

Get back to the trailer park and let the big people handle this problem, okay sweetie?

This raises an interesting point. For all those years except 2008, Pittsburgh was "hell with the lid off" because of all the smog and pollution. So isn't it possible that the temps were high because of the man-made contribution to nasty air?

[FONT=Arial, Helvetica, sans-serif]"Almost from its beginnings as a city, bituminous coal provided cheap and easily obtainable high-quality fuel to the people of Pittsburgh. But while high in terms of its BTU content, bituminous coal was also a dirty fuel producing effluents such as carbon dioxide, mercury, and arsenic when consumed. Over the years the city and surrounding areas were heavily mined, with the result that piles of mining wastes littered the countryside, acid mine drainage destroyed life in streams, and hundreds of miles of mine tunnels honeycombed the land.

Smoke pollution was the most visible byproduct of coal consumption, with atmospheric inversions in the city and in the region exacerbating conditions. Smoke's link with industrial prosperity made control of the problem difficult. A smoke control movement developed after the city experienced a brief clean air period in the 1880s and early 1890s due to a brief natural gas boom. But smoke control ordinances and a Bureau of Smoke Control produced only minimal results because of weak regulations and enforcement, and imperfect control technologies.

Throughout the period between the two world wars, smoke in Pittsburgh continued to be a serious problem. In 1940, however, after St. Louis had improved its air quality by passing ordinances requiring the use of clean fuel or mechanical combustion equipment, Pittsburgh followed its lead. The ordinance resulted from a consensus that promised that the air could be cleaned by using treated local coal, therefore creating a new industry and maintaining local coal mining jobs. What eventually reduced most of the smoke was the piping of clean natural gas into the city from the Southwest, although the smoke control ordinance should be given credit for accelerating the change. Additionally, the decision by the Pennsylvania Railroad and other regional railroads in the 1950s to shift from coal-burning to diesel-electric locomotives helped to improve air quality significantly in the region. Control of the smoke made possible the cleaning of buildings of their soot burden and the replanting of hillsides, providing the city with a green ambience.
But while smoke pollution was considerably reduced by the 1960s, the metals industry, particularly iron and steel manufacturing, resisted control of their gaseous effluents. In the 1970s and 1980s, however, the efforts of the advocacy organization Group Against Smoke and Pollution (GASP), working to encourage local enforcement of the Clean Air Act, brought about some improvement. But perhaps the most substantial air quality improvements came because of the collapse of the iron and steel industry in the 1980s. Today, pollution from the by-products of coking facilities and automobiles are the greatest source of air pollution in the region.

A very valid point. However, there is a consistency issue. My point was to illustrate that it had happened several other times in the past. While I would tend to agree that the pollution of the late 1800's and early 1900's certainly would lend to the assertion you make, I would then ask why it spiked only at times and what were the other variables that caused lower temps in other years?

Weather patterns have and always will vary. The climate has, is and always will be changing. Pretending that man is somehow the primary driver is not supported by the actual data. The computer models that were shown to us in the late 90's early 2000's have been shown to be wrong. Yet the non stop fear mongering from so called 'climate scientists' (ask one of them what extra science courses they needed for this designation) continues unabated.

Smog tends to be caused when you have a temperature inversion and the area affected is in a depression surrounded by higher ground.
