Climatologist Dr. Pat Michaels suggests feds altering temperature data for political reasons: ‘The raw temperature data is continually adjusted to show more warming’
PATRICK J. MICHAELS and PAUL C. "CHIP" KNAPPENBERGER: U.S. temperature 'history has been repeatedly “revised” to either make temperatures colder in the earlier years or warmer at the end' - 'A major and ongoing federal effort has been to try and cram these numbers into the box imposed by the theory that gives the government the most power—i.e., strong global warming.'
'Please be advised that this history has been repeatedly “revised” to either make temperatures colder in the earlier years or warmer at the end. Not one “adjustment” has the opposite effect, a clear contravention of logic and probability. While the US has gotten slightly warmer in recent decades, compared to the early 20th century, so have the data themselves. It’s a fact that if you just take all the thousands of fairly evenly-spaced “official” weather stations around the country and average them up since 1895, that you won’t get much of a warming trend at all. Consequently a major and ongoing federal effort has been to try and cram these numbers into the box imposed by the theory that gives the government the most power—i.e., strong global warming.'
