I’ve been documenting for a decade how NASA has been hiding the past warmth in Iceland by repeatedly tampering with temperature data.

And now they have started tampering with the unadjusted data as well – to cool the past and warm the present, and make the warmth of the 1940s disappear.

“Progressives” have never had a problem changing history, or reality, to agree with their viewpoint. And whenever reality tends to wobble outside their parameters they get anxious and start hammering things back in shape.
Since the manipulations by NASA and NOAA “make” the resultant temperatures perfectly match the CO2 global warming theory, one can say that the manipulation curve, the amount of alteration vs time, is actually a representation of how poorly the CO2 theory reflects reality. If the CO2 theory actually matched reality, then there would be no need to adjust the data and the manipulation curve would have a slope of 0. However the curve has an average slope of about +2 degrees (F) per century. Even worse the need to adjust the temperature to match the theory is exponential, requiring greater adjustments as time moves forward. So by their manipulations, they are proving that their theory in no way matches reality and is increasingly off.
But the original temperature data is bad!!! Ok, so what? The temperature gathering stations were located and arranged as best as the scientists at the time could make them record the “true” temperature at that time and location. All of these temperature readings, some high, some low, and some just right, flow from each temperature station through time with the same biases. As a data cloud they represent temperature sets that continue to have the same biases through time, so any temperature change of the set is representative of the real world even if the absolute temperatures are not correct. I.e. it’s the delta T through time that is important, not the absolute temperature. So what about station changes? Well they should have done side by side data runs to figure out the adjustment needed. What about urban encroachment and other anthropogenic microclimate factors? Well these always force the local microclimate near the station toward higher temperatures. They never cause cooling. So any temperature adjustment for man should be downward in the present to compensate for urban heat islands. In no way should adjustments be downward in the past. Clearly, everything that NASA does to the data set has no legitimate
real world impetus.
“Who controls the past, controls the future: who controls the present, controls the past. The mutability of the past is the central tenet of Ingsoc.* Past events, it is argued, have no objective existence, but survive only in written records and in human memories. The past is whatever the records and the memories agree upon. And since the Party is in full control of all records, and in equally full control of the minds of its members, it follows that the past is whatever the Party chooses to make it.”
