An independent climate science think tank produces evidence from a leading infrared thermometer manufacturer proving that climatologists were mistakenly taking incorrect readings of atmospheric temperatures. Latest findings are set to trigger a paradigm shift in climate science.
Researchers from Canada, USA, Mexico and Britain this week announce a startling discovery that destroys 20 years’ of thinking among government climatologists.
Climate scientists had long believed infrared thermometers measured thermal radiation from the atmosphere and assumed it was 'proof' of the greenhouse gas effect (GHE). Their assumption was that infrared thermometers (IRT’s) were measuring ‘back radiated’ heat from greenhouse gases (including water vapor and carbon dioxide). But damning new evidence proves IRT's do no such thing.
Now a world-leading manufacturer of these high-tech instruments, Mikron Instrument Company Inc
., has confirmed that IRT’s are deliberately set to AVOID registering any feedback from greenhouse gases. Thus climate scientists were measuring everything but the energy emitted by carbon dioxide and water vapor.
One of the researchers involved, Alan Siddons, has analyzed the GHE for over six years. He has long condemned the practice of using IRT’s as a means of substantiating the increasingly discredited hypothesis.
In 2010 Siddons and his colleagues debated the GHE issue with fellow global warming skeptic, and GHE believer, Dr. Roy Spencer. An unmoved Spencer posted the following on his blog (August 8, 2010 at 6:38 AM):
“The IR thermometer DOES see the atmosphere immediately in front of it, as well as most of the rest of the atmosphere along its line of sight… The final calibrated brightness temperature can be roughly considered to be the weighted average temperature of all of those layers.”
But Siddons quashes Spencer's assumptions quoting from manufacturers, Mikron Instrument Company Inc (MIC), who state:
“Whereas the early IRT's required a broad spectral band of IR [infrared] to obtain a workable detector output, modern IRT’s routinely have spectral responses of only one micron.” [1.].
The company explains why this is so: “instruments necessarily need to have this selective and narrow spectral response to allows the IR thermometer to see through atmospheric or other interference.”
MIC goes further to advise that IRT’s are routinely calibrated for selective spectral responses of only 8-14 microns [2.]. The company says IRT's are set to evade atmospheric moisture over long path measurements. This, they say, is necessary to “avoid interference from CO2 and H2O.”
Yet on August 7, 2010 at 4:04 AM Dr. Spencer asserts the following on his blog:
“For an IR thermometer sensitive to wavelengths from, say, 8 to 14 microns, you could plot a weighting function profile that shows the proportions of IR energy being received from different altitudes.”
Clearly, from the above statement Spencer has identified a spectral range in which his instrument CANNOT detect any IR energy from CO2 or water vapor, thus making any such “plot” pointless and absurd for the purpose he is trying to prove.
Thus Siddons ably demonstrates that when Spencer was pointing his IRT at the sky he was deluding himself that he was measuring the energy of ‘greenhouse gases.’ Thus Spencer’s erroneous assumption that infrared thermometers prove the existence of ‘back radiation’ coming from carbon dioxide (CO2) is refuted.
Mexican Study Shows IRT’s Actually Measuring ‘Rising Hot Air’
Professor Nasif Nahle in his latest report on "back radiation” further exposes the shocking misuse of radiometers and Infrared thermometers by climate scientists.
Nahle’s study proves, “they merely detect thermal radiation emitted by relatively small hot globules of air rising vertically in the atmosphere.”
“The records would depend on the altitude of those globules. For example, a globule radiating 60 W/m^2 would be at 30 km in altitude; globules at surface level, which start rising and are very hot because they are in contact with the hotter surface, would emit around 92 W/m^2, etc.”
Fellow independent climate analyst, Joe Olson from Texas, added that Nahle’s discovery “removes this dangerous weapon from the Sky Dragons’ toolbox once and for all.”
Olson, along with Siddons, Nahle and Canadian astrophysicist, Joseph Postma have been collaborating with two dozen other well-qualfied experts for over a year on this international project. The team are addressing in great detail the flaws of the greenhouse gas effect, a cornerstone of the science of the discredited Intergovernmental Panel on Climate Change (IPCC).
The Fatal False Assumption of Greenhouse Gas Effect Believers
But Spencer can be forgiven for his false assumptions because he is in very large company; almost all climatologists have fallen into the same trap. To his great credit, Spencer is one of the few such experts willing to even debating the existence of a GHE.
Astrophysicist, Joe Postma chips in to explain that:
“When pointed horizontally, the IRT sensor will report the ambient air temperature. When pointed vertically, it gives a reading for the integrated average temperature of the vertical air-column, weighted for optical depth “penetration” of the instrument.”
Postma advises us:
“So think about that. If ANY parcel of air emitted the full intensity of the Stefan-Boltzman Equation, then when that sensor was pointed straight up, it STILL HAD a cubic meter of warm, ground-temperature air directly above it, just like it did when it was pointing horizontally.”
The air has to emit SOME radiation though, because any ensemble of particles with a temperature higher than absolute zero (0 degrees Kelvin) emits thermal radiation.
Siddons, Postma, Nahle and their Slayers think tank colleagues have a point; Mikron Instrument Company Inc. has thrown into the mix an important caveat for consideration for those who misinterpret the readings from IR thermometers.
So it is the company that builds IR thermometers that destroys another cornerstone of the religion of the ‘greenhouse gas effect.’ For further compelling examples of how the indomitable ‘Slayers’ have debunked IPCC junk science visit here.
