First Six Months of 2014 No Warmer Than Historical Average in Contiguous USA

NOAA has released its June 2014 temperature data for the contiguous United States, and with it we find that the temperature during the first six months of 2014 has been equal to the 20th-century average. Since 1998, we have a statistically significant cooling trend in the USA's average temperature for the first half of each year.  Over the past 30 years – which climate scientists (and Associated Press science journalists) like to tell us is a rigorous indicator of climate trends, there has been no significant trend, and the correlation is even negative (i.e., cooling). The contiguous U.S. temperature over the past 12 months has also been no warmer than the 20th-century average, with no significant trend during the last 30 years, either. And the precipitation over the first six months of 2014 in the contiguous U.S. was exactly equal to the 20th-century average, and there has been absolutely no significant trend in this variable since records began in...(Read Full Post)
