The robust Pause resists a robust el Niño Still no global warming at all for 18 years 9 monthsPosted: December 5, 2015
With the ever increasing divergence of surface temperatures from satellite ones, and the subsequent divergence of overheated climate models to observed reality, it is worth a background on atmospheric measurement systems from former NASA climate scientist Dr. Roy Spencer, Ph.D. – climatologist at the University of Alabama in Huntsville who he developed the first temperature record based on satellites…
Roy Spencer On Satellite (UAH / RSS) v Surface Temperature Data (NASA GISS) :
I claim 2014 won’t be the warmest global-average year on record.
..if for no other reason than this: thermometers cannot measure global averages — only satellites can. The satellite instruments measure nearly every cubic kilometer – hell, every cubic inch — of the lower atmosphere on a daily basis. You can travel hundreds if not thousands of kilometers without finding a thermometer nearby.
(And even if 2014 or 2015 turns out to be the warmest, this is not a cause for concern…more about that later).
The two main research groups tracking global lower-tropospheric temperatures (our UAH group, and the Remote Sensing Systems [RSS] group) show 2014 lagging significantly behind 2010 and especially 1998:
With only 3 months left in the year, there is no realistic way for 2014 to set a record in the satellite data.
Granted, the satellites are less good at sampling right near the poles, but compared to the very sparse data from the thermometer network we are in fat city coverage-wise with the satellite data.
In my opinion, though, a bigger problem than the spotty sampling of the thermometer data is the endless adjustment game applied to the thermometer data. The thermometer network is made up of a patchwork of non-research quality instruments that were never made to monitor long-term temperature changes to tenths or hundredths of a degree, and the huge data voids around the world are either ignored or in-filled with fictitious data.
Furthermore, land-based thermometers are placed where people live, and people build stuff, often replacing cooling vegetation with manmade structures that cause an artificial warming (urban heat island, UHI) effect right around the thermometer. The data adjustment processes in place cannot reliably remove the UHI effect because it can’t be distinguished from real global warming.
Satellite microwave radiometers, however, are equipped with laboratory-calibrated platinum resistance thermometers, which have demonstrated stability to thousandths of a degree over many years, and which are used to continuously calibrate the satellite instruments once every 8 seconds. The satellite measurements still have residual calibration effects that must be adjusted for, but these are usually on the order of hundredths of a degree, rather than tenths or whole degrees in the case of ground-based thermometers.
And, it is of continuing amusement to us that the global warming skeptic community now tracks the RSS satellite product rather than our UAH dataset. RSS was originally supposed to provide a quality check on our product (a worthy and necessary goal) and was heralded by the global warming alarmist community. But since RSS shows a slight cooling trend since the 1998 super El Nino, and the UAH dataset doesn’t, it is more referenced by the skeptic community now. Too funny.
In the meantime, the alarmists will continue to use the outdated, spotty, and heavily-massaged thermometer data to support their case. For a group that trumpets the high-tech climate modeling effort used to guide energy policy — models which have failed to forecast (or even hindcast!) the lack of warming in recent years — they sure do cling bitterly to whatever will support their case.
As British economist Ronald Coase once said, “If you torture the data long enough, it will confess to anything.”
So, why are the surface thermometer data used to the exclusion of our best technology — satellites — when tracking global temperatures? Because they better support the narrative of a dangerously warming planet.
Except, as the public can tell, the changes in global temperature aren’t even on their radar screen (sorry for the metaphor).
2015 “Hottest Year Ever” Update :
By Christopher Monckton of Brenchley
The Christmas pantomime here in Paris is well int0 its two-week run. The Druids who had hoped that their gibbering incantations might begin to shorten the Pause during the United Necromancers’ pre-solstice prayer-group have been disappointed. Gaia has not heeded them. She continues to show no sign of the “fever” long promised by the Prophet Gore. The robust Pause continues to resist the gathering el Niño. It remains at last month’s record-setting 18 years 9 months (Fig. 1).
Figure 1. The least-squares linear-regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset continues to show no global warming for 18 years 9 months since February 1997, though one-third of all anthropogenic forcings have occurred during the period of the Pause.
The modelers ought to be surprised by the persistence of the Pause. NOAA, with rare honesty, said in its 2008 State of…
