Where's the Tropospheric Warming?

Satellite Global Temperature Measurements:

November 30 marked the 33rd year of the data record of using satellite data to calculate atmospheric temperatures. Published monthly, these data are the most comprehensive and rigorous collection of global temperatures in existence. When adjusted for volcanic cooling events and unusually strong El Niño warming events, the data from the lower troposphere show little global warming over the entire record. The lower troposphere is precisely where the climate models predict the warming should take place, especially above the tropics. The recorded warming is largely above 60 degrees North Latitude, especially the Arctic.

University of Alabama, Huntsville, scientists Roy Spencer and John Christy are to be congratulated and esteemed for their scientific efforts and scientific integrity in consistently publishing the results of their findings, regardless of short warming or cooling periods.

The notes accompanying the release of the data state: "While Earth's climate has warmed in the last 33 years, the climb has been irregular. There was little or no warming for the first 19 years of satellite data. Clear net warming did not occur until the El Niño Pacific Ocean 'warming event of the century' in late 1997. Since that upward jump, there has been little or no additional warming."

"Christy and other UA Huntsville scientists have calculated the cooling effect caused by the eruptions of Mexico's El Chichon volcano in 1982 and the Mt. Pinatubo volcano in the Philippines in 1991. When that cooling is subtracted, the long-term warming effect is reduced to 0.09 C (0.16° F) per decade, well below computer model estimates of how much global warming should have occurred."

Of course, these measurements contradict the land surface measurements of temperatures so widely cited as proof of human-caused global warming. Please see links under "Challenging the Orthodoxy."
