Global Warming
1
Most of the evidence concerning U.S. temperature trends is collected by NOAAs National Data Climatic Center which gathers information from about 1,200 weather observation stations across the nation. These stations are small wooden sheds with thermometers, which are read at intervals, mostly by volunteers. Many are located in sprawling urban and industrial centers, known as heat islands, and are subject to higher readings than stations in rural areas where temperatures are subject mostly to land use effects.
Most of the recent global-warming alarmists use 1998 as the benchmark for the hottest year on record, but it turns out that their reporting is flawed, the result of a math blunder.
In fact, 1934 was the hottest year on record, and four of the ten hottest years in the U.S. were recorded in the 1930s. The second hottest year on record was 1998, but the third hottest was 1921, not 2006. Notably, six of the ten hottest years occurred prior to 90 percent of the economic growth associated with increased greenhouse-gas emissions.
Update: I am still....STILL waiting for loerke or any other gullible believer in man-made global warming to tell us what the mean temperature of the earth SHOULD be. If they cannot answer that question, their arguments have no validity whatsoever.
