So, a major government climate data set is adjusting recent years temperature reading upward, at an increasing rate. This implies that the data as collected at the sensors is getting increasingly inaccurate - after all, we're seeing adjustments on the order of 0.5°F for the 1990s, so the sensors are clearly reading almost half a degree cold.Peer-reviewed Science™ this week:
Does this make any sense? And notice how the sensors are "running cold", never hot, despite the fact that cities have grown much larger since 1960, and many once-rural weather stations are now surrounded by hot asphalt parking lot, rather than cooler meadow? Does that make any sense?
ABSTRACTThe objective of this research was to test the hypothesis that GlobalAverage Surface Temperature (GAST) data, produced by NOAA, NASA, and HADLEY, are sufficiently credible estimates of global average temperatures such that they can be relied upon for climate modeling and policy analysis purposes.…In this research report, the most important surface data adjustment issues are identified and past changes in the previously reported historical data are quantified. It was found that each new version of GAST has nearly always exhibited a steeper warming linear trend over its entire history. And, it was nearly always accomplished by systematically removing the previously existing cyclical temperature pattern. This was true for all three entities providing GAST data measurement, NOAA, NASA and Hadley CRU. As a result, this research sought to validate the current estimates of GAST using the best available relevant data. This included the best documented and understood data sets from the U.S. and elsewhere as well as global data from satellites that provide far more extensive global coverage and are not contaminated by bad siting and urbanization impacts. Satellite data integrity also benefits from having cross checks with Balloon data.
Eight years later, we're actually seeing peer-reviewed scientific papers answering my question: Does this make any sense?The conclusive findings of this research are that the three GAST data sets are not a valid representation of reality. In fact, the magnitude of their historical data adjustments,that removed their cyclical temperature patterns, are totally inconsistent with published and credible U.S. and other temperature data. Thus, it is impossible to conclude from the three published GAST data sets that recent years have been the warmest ever – despite current claims of record setting warming. [My emphasis - Borepatch]
Their peer-reviewed answer: no.
The implications are huge. As I said in my post:
Like I said recently, almost every climate scientist uses data from one of a very small number of data sets. If the people who control the data sets can inject a warming signal, then you will indeed reach a consensus that the climate has been warming. All scientists using those data sets will find the warming signal. The science will, in a sense, be "settled".What is astonishing is that this paper was actually published. It's conclusions are so, so not helpful for the current Government power grab.
It will be wrong, but it will be settled.
