We have written many times about the fact that the scientific agencies which are keepers of the world’s historical temperature data are all, or nearly all, under the control of warmists. These warmists have systematically altered historic temperature records, so that the temperatures they report today for past eras are not the same as what were measured, say, 70 or 80 years ago. The effect of these adjustments is strikingly consistent: they almost always make the past look cooler than it was measured at the time, so that the present looks warmer by comparison. The opposite–an adjustment that results in reporting a historic temperature higher than what was published contemporaneously–never, or almost never, happens. These adjustments may or may not be explained; sometimes, they are kept quiet until someone stumbles across the original data and points out a discrepancy.
A man named Paul Homewood, an accountant by profession, has taken it upon himself to research this issue of unexplained temperature adjustments. He reports on his findings atNot a Lot of People Know That. His site is worth checking out, as he is producing a lot of highly relevant data.
One of the areas that Homewood has looked at is Paraguay. In a post titled All of Paraguay’s temperature record has been tampered with, he found that GISS has systematically altered temperature records to make the past look cooler and the present warmer, and to create an entirely fictitious warming trend.
To show his findings, Homewood created animated GIFs of the data from each weather station in Paraguay, contrasting the “old” data–the data actually recorded by thermometers and reported at the time–with the “new” data, i.e., the massaged numbers that GISS now publishes. Here they are. The deception is obvious:
Let me state again. These warming adjustments have taken place at every single, currently operational site in Paraguay. …
What is perhaps most telling is that we have not heard a word from NCDC or GISS. We expect the jokers from BEST to jump in, but this data and the associated adjustments are from NCDC and GISS.
Serious accusations have been levelled against them in the media, yet they have not responded or attempted to defend their data. Instead, they seem intent to sweep the matter under the carpet, just as they did last summer when they told us “the system was working as it was supposed to”!
This kind of thing is going on all over the world. It is one of the reasons why the satellite data (which, however, go back only to 1979) are so important: they have not been corrupted.
