Need your climate adjusted? – call Dr. James Hansen at GISS. Below is a chronology of the destruction and politicization of the US and global temperature record. The Northern Hemisphere used to have a broken hockey stick problem. According to the National Academy Of Sciences in 1975, the hemisphere had cooled 0.7C since the 1930s, and was colder than it was at the turn of century.
Dr. Hansen realized he had a problem when he took over – that data didn’t look anything like a hockey stick. So he fixed it! You can do such cool stuff when you are pushing an agenda, and you control the historical record.
The figure below shows Hansen’s remarkable changes to the pre-1975 temperature data. He simply removed that pesky warm period from 1890 to 1940.
But that was just the beginning of Hansen’s history rewrite. He had another problem – the United States. Until the year 2000, the US temperature graph looked almost identical to the 1975 NAS Northern Hemisphere graph. fig1x.gif (500×182)
Hansen’s problem was that he had fixed the data for the rest of the world, but the US data was still not looking like a hockey stick.
Phil Jones and NOAA had clearly stated that there was no warming in the US.
February 04, 1989 Last week, scientists from the United States Commerce Department’s National Oceanic and Atmospheric Administration said that a study of temperature readings for the contiguous 48 states over the last century showed there had been no significant change in average temperature over that period. Dr. (Phil) Jones said in a telephone interview today that his own results for the 48 states agreed with those findings. Global Warmth In ’88 Is Found To Set a Record – New York Times
In 1999, Hansen himself said that he didn’t see anything happening in the US.
Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought. The drought of 1999 covered a smaller area than the 1988 drought, when the Mississippi almost dried up. And 1988 was a temporary inconvenience as compared with repeated droughts during the 1930s “Dust Bowl” that caused an exodus from the prairies, as chronicled in Steinbeck’s Grapes of Wrath…..
in the U.S. there has been little temperature change in the past 50 years, the time of rapidly increasing greenhouse gases — in fact, there was a slight cooling throughout much of the country
Undaunted by reality, all the evidence, and millions of temperature records – in the year 2000 Dr. Hansen and Tom Karl at NOAA adjusted the US temperature record to make it look like Hansen’s already adjusted global temperature record.
Below is an animation of their handiwork. 1934 was no longer the hottest year, and the 1930s was no longer the hottest decade. Hansen essentially erased the Dust Bowl.
Conclusion. US and global surface temperature records are so corrupted as to be meaningless. Below are some news stories from the 1930s. July of 1936 was the hottest month in US history. The summer of 1934 was the worst drought in US history. Half of the lower 48 states set their all-time temperature record during the 1930s. The most powerful hurricane to ever hit the US happened in 1935.
