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.
These 3,000 yellow sentinels -- about the size and shape of a large fencepost -- 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.
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 Argos 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.
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.
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.
