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.
