From the Telegraph:
When future generations look back on the global-warming scare of the past 30 years, nothing will shock them more than the extent to which the official temperature records – on which the entire panic ultimately rested – were systematically “adjusted” to show the Earth as having warmed much more than the actual data justified.
Two weeks ago, under the headline “How we are being tricked by flawed data on global warming”, I wrote about Paul Homewood, who, on his Notalotofpeopleknowthat blog, had checked the published temperature graphs for three weather stations in Paraguay against the temperatures that had originally been recorded. In each instance, the actual trend of 60 years of data had been dramatically reversed, so that a cooling trend was changed to one that showed a marked warming.
This was only the latest of many examples of a practice long recognised by expert observers around the world – one that raises an ever larger question mark over the entire official surface-temperature record. Following my last article, Homewood checked a swathe of other South American weather stations around the original three. In each case he found the same suspicious one-way “adjustments”.
First these were made by the US government’s Global Historical Climate Network (GHCN). They were then amplified by two of the main official surface records, the Goddard Institute for Space Studies (Giss) and the National Climate Data Center (NCDC), which use the warming trends to estimate temperatures across the vast regions of the Earth where no measurements are taken. Yet these are the very records on which scientists and politicians rely for their belief in “global warming”.
Homewood has now turned his attention to the weather stations across much of the Arctic, between Canada (51 degrees W) and the heart of Siberia (87 degrees E). Again, in nearly every case, the same one-way adjustments have been made, to show warming up to 1 degree C or more higher than was indicated by the data that was actually recorded.GO READ THE WHOLE THING.

I went through the Canadian figures two years ago, one of the coldest winters ever. The Canadian Met. office have a site where they list the hourly high/low temperature for every hour of every day since 1953.
I took 12 noon one cold December day, noted the temperature for that hour of the day for nearly sixty years and since weather, unlike climate can change from year to year averaged the temperature over ten years to get a more reliable reading for the day.
The result: fraction of a degree rise since 1953, slightly higher in the 90's but since dropped back to the fraction.
Now comes the kicker. Most of the weather stations IN THE WORLD are at airports, they were in the early days essential for aviation. Since the 50's airports have gone from some small rural flying fields deliberately sited out of towns to become small towns on their own. Towns where the urban heat build up is far greater then in actual towns because there is far more black heat absorbent tarmac both in terms of runways and parking. From air and road traffic there is also far more CO2 than in even the most polluted city and to top it all,
practically no trees for miles. It has been policy to chop all trees on all approaches as a safety measure in case of crashes.
