The geniuses in the global warming community tell us that the US heatwave of 2012 is due to the background of a warming climate.
July of 2009 was the coldest on record in the Ohio Valley, and July temperatures have been plummeting in that region since 1930. July 1934 and 1936 were both much hotter – even after NCDC adds 1.5 degrees on to recent temperatures relative to the 1930s.
Yep. Get away from the marine and UHI influences, and this is what you get.
Wow, you know it’s bad when the NCDC has a cooling trend, it must have really cooled off.
Two points:
1. Regional variation in the context of a larger-scale national, hemispheric, and global rise in temperatures can occur.
2. Selective sampling can lead to biased results. If one calculated the trend line from all the possible starting points (1895 through 1982 toassure a period of at least 30 years, the minimum climatic base period) through 2011, about 75% of the trend lines would be positive. Selectively sampling from an anomalously warm period can skew the results.
Try using your thought process to reach a sensible conclusion.
I am not the one claiming that this summer proves global warming, rather I am showing that people who claim otherwise don’t know what they are talking about.
Regional temperatures in populated areas have no meaning. Only Hansen’s adjustments and extrapolations in unpopulated areas have meaning.
Rural temperatures must be contaminated by all cities within 1200km before they can be properly analyzed.
