Both the Microwave Sounding Unit (MSU) satellite (analyzed by the University of Alabama in Huntsville by John Christy and Roy Spencer) and weather balloon data (trends reported by a number of researchers, notably Jim Angell at NOAA) have failed to show significant warming since the satellite record began in late 1978, even though the surface record has been rising at its fastest pace (~ 0.15 C / decade) since instrumental records began.

Citing the work of Dr. John Christy and Richard McNider at the University of Alabama in Huntsville (UAH), which compared climate model projections with temperatures measured independently by satellites and weather balloons, he said «the average warming predicted to have occurred since 1979 (when the satellite data starts) is approximately three times larger than what is being observed.»

Measurements by weather balloons, the main method used to measure temperatures at the time, only test a small sliver of the atmosphere and are far from comprehensive.

But instead they deny the importance of 28 million weather - balloons, call the missing heat a «travesty», they pretend that if you slap enough caveats on the 1990 report and ignore the actual direct quotes they made at the time, then possibly, just maybe, their models are doing OK, and through sheer bad luck 3000 ocean buoys, millions of weather balloons, and 30 years of satellite records are all biased in ways that hides the true genius of the climate models.

To calculate the molar densities from the weather balloon measurements, we converted all of the pressures and temperatures into units of Pa and K, and then determined the values at each pressure using D = n / V =P / RT, where R is the ideal gas constant (8.314 J / K / mol)
