Atmospheric Temperature and Rising CO2 Levels Do Not Correlate In Last Decade

The following short article illustrates the disconnect between atmospheric temperature and CO2 levels. I think everyone agrees that surface temperature measurements are of dubious validity for a variety of reasons. These include but are not limited to 1) calibration of instruments, 2) location of measuring stations, and 3) the urban heat island effect.

The following average atmospheric temperatures are derived from satellite measurements, thus they have a much greater sampling area, with calibrated instruments, are not subject to local variations, and thus these satellite temperature measurements are considered the most accurate measure of global atmospheric temperatures.

The article goes into more detail, but the key point here, that is so clearly shown in the second graph, is that in spite of steadily increasing carbon dioxide levels, the atmospheric temperature is not rising. This simple observation is completely counter to computer models and predictions of global warming as a result of burning fossil fuels and adding the resultant carbon dioxide to the atmosphere.

If there is no significant recent atmospheric warming, then carbon dioxide emissions must not be a problem. Can anyone question this data, and its interpretation?

And by the way, the source of this article is from an excellent web site titled ICECAP and is located here:

They have an impressive list of science advisors and contributors. I highly recommend you examine what they offer.

Global Temperatures are Uncorrelated with Carbon Dioxide Trends This Last Decade
By Joseph D’Aleo, CCM
Temperature peaked in 1998 and have shown no warming for a decade now. Many scientists have been remarking about this trend for several years but no one takes heed, preferring to believe models than actual data. Here is the satellite derived global temperature trend since 1979. Note the cooling globally near the volcanically active periods of the early 1980s and 1990s. Note also the warm spike associated with the super El Nino that seemingly marked the beginning of the end of the warm Pacific trend that began in 1978.

Note the subsequent cooling as a series of 3 La Ninas in 4 years helped cool the earth in the late 1990s. Temperatures rebounded a bit in the early 2000s with a slight rebound in the Pacific warmth, three El Ninos and a volcanic aerosol-free stratosphere, but the trend since 2001 has been flat and at a level considerably below the peak of 1998. This lack of warming has occurred despite the increases in carbon dioxide. Indeed, when comparing this satellite derived temperature trend the last decade with the carbon dioxide increases as seasonally adjusted from Scripps, we find NO CORRELATION (just 0.07 r squared!!!)
