Christopher Burt keeps track of weather extremes at Weather Underground, and provides huge amounts of valuable information that I frequently reference. But he has been snookered by tampered NOAA temperature data.
He published this graph showing that the past decade has had the hottest summers in the US, which is utter nonsense.
The 1930s were by far the hottest decade in the US. Maximum temperatures were about two degrees warmer. Afternoon summer temperatures are no warmer now than they were in the 19th century.
Average daily temperatures were also much warmer, even with UHI effects bringing up nighttime temperatures.
So what is wrong with Dr. Burt’s analysis? He is using tampered temperature data from NOAA. For example, his data set shows the hottest summer in Wichita Kansas as being 2011. The two closest HCN stations to Wichita show that 1934, 1936, 1954 and 1980 all were hotter.
NCDC massively adjusts US summer temperatures, cooling the past. This creates the appearance of a non-existent warming – and leads good scientists like Dr. Burt to the wrong conclusion.
Hot days were far more common and widespread in the 1930s.
The past decade was nowhere near as hot as the 1930’s in the US. Data tampering by NOAA destroys climate science, and causes good scientists to reach wrong conclusions.
