Perhaps the climate change models are wrong

They drift along in the worlds' oceans at a depth of 2,000 metres -- more than a mile deep -- constantly monitoring the temperature, salinity, pressure and velocity of the upper oceans.
Then, about once every 10 days, a bladder on the outside of these buoys inflates and raises them slowly to the surface gathering data about each strata of seawater they pass through. After an upward journey of nearly six hours, the Argo monitors bob on the waves while an onboard transmitter sends their information to a satellite that in turn retransmits it to several land-based research computers where it may be accessed by anyone who wishes to see it.
These 3,000 yellow sentinels --about the size and shape of a large fence post -- free-float the world's oceans, season in and season out, surfacing between 30 and 40 times a year, disgorging their findings, then submerging again for another fact-finding voyage.
It's fascinating to watch their progress online. (The URLs are too complex to reproduce here, but Google "Argo Buoy Movement" or "Argo Float Animation," and you will be directed to the links.)
When they were first deployed in 2003, the Argos were hailed for their ability to collect information on ocean conditions more precisely, at more places and greater depths and in more conditions than ever before. No longer would scientists have to rely on measurements mostly at the surface from older scientific buoys or inconsistent shipboard monitors.
So why are some scientists now beginning to question the buoys' findings? Because in five years, the little blighters have failed to detect any global warming. They are not reinforcing the scientific orthodoxy of the day, namely that man is causing the planet to warm dangerously. They are not proving the predetermined conclusions of their human masters. Therefore they, and not their masters' hypotheses, must be wrong.
In fact, "there has been a very slight cooling," according to a U.S. National Public Radio (NPR) interview with Josh Willis at NASA's Jet Propulsion Laboratory, a scientist who keeps close watch on the Argo findings.
Dr. Willis insisted the temperature drop was "not anything really significant." And I trust he's right. But can anyone imagine NASA or the National Oceanic and Atmospheric Administration (NOAA) or the Intergovernmental Panel on Climate Change -- the UN's climate experts -- shrugging off even a "very slight" warming.
A slight drop in the oceans' temperature over a period of five or six years probably is insignificant, just as a warming over such a short period would be. Yet if there had been a rise of any kind, even of the same slightness, rest assured this would be broadcast far and wide as yet another log on the global warming fire.
Just look how tenaciously some scientists are prepared to cling to the climate change dogma. "It may be that we are in a period of less rapid warming," Dr. Willis told NPR.
Yeah, you know, like when you put your car into reverse you are causing it to enter a period of less rapid forward motion. Or when I gain a few pounds I am in a period of less rapid weight loss.
The big problem with the Argo findings is that all the major climate computer models postulate that as much as 80-90% of global warming will result from the oceans warming rapidly then releasing their heat into the atmosphere.
But if the oceans aren't warming, then (please whisper) perhaps the models are wrong.
The supercomputer models also can't explain the interaction of clouds and climate. They have no idea whether clouds warm the world more by trapping heat in or cool it by reflecting heat back into space.
Modellers are also perplexed by the findings of NASA's eight weather satellites that take more than 300,000 temperature readings daily over the entire surface of the Earth, versus approximately 7,000 random readings from Earth stations.
In nearly 30 years of operation, the satellites have discovered a warming trend of just 0.14 C per decade, less than the models and well within the natural range of temperature variation.
I'm not saying for sure the models are wrong and the Argos and satellites are right, only that in a debate as critical as the one on climate, it would be nice to hear some alternatives to the alarmist theory.
