You will recall how offended I was to discover that the East Anglia academics were going back and changing earlier data to make it conform to their political ideology. I had some of the earlier data and could not believe my eyes as they changed the data and gave a stupid convoluted explanation of their reasons.
It now turns out that my own government is doing the same stupid convoluted political nonsense.
This all began as I looked into the statement that 2012 was the hottest year in the continental United States on record.
First of all, this disclosure was perverted because it did not include Alaska which is 17% of the landmass of the US. When Alaskan data is put back into the totals, the 2012 year was not the highest.
Second, the number that is given for the highest temperature of the past century and a half is based on an average of daily highs and lows. That is not an average. If you took the average of the tallest and shortest people to walk into a coffee shop in one day you would not have the average height of the people in that coffee shop. You would be better off averaging the height of every 10th person. Height is skewed. The year 2012 was also the year of warmer than trend nights.
Third in the very document from which the press release was compressed the statement is made that "the United States has experienced warming trend equal to .06°F per century". That is 6/100 of 1°F. Most mercury thermometers are not accurate beyond 0.9°F. This anti-global warming fact was not included in the press release from our government agencies.
Lastly, our weather agencies are going back in history to correct the data. According to their absolutely convoluted statement they have divided the United States into a grid pattern and are creating averages for each grid. They are removing data that gives too much information for any one grid and extrapolating for any grid that lacks data.
I spent my professional lifetime looking at data and can state empirically that you have more reliable data when you don't try to create missing numbers.
One reason given for removing data is that urban areas create heat islands. Presumably urbanization increases air temperature. This may or may not be true. I looked at the data for 140 years of Salt Lake City which went from desert to sprawling city and found no change whatsoever in the temperature over that period.
What heat island has been proven?
All in all our government is dishonest with climate data and scientists and those associated with scientists are tragically corrupt bunch.
