Thermometers on the ground, measuring the near-surface air temperature, demonstrate a marked increase in globally-averaged temperature over the past two decades. Computer models of global warming predict that the temperature trend in the Earth's thick lower atmosphere, called the lower troposphere, should be experiencing an even more pronounced warming that increases smoothly with altitude. And yet, satellite observations of the temperature of the Earth's lower troposphere do not reveal any overall warming trend.
Facing comment to appease the global warming mob cut.
These results will be presented today (February 6) at the 77th meeting of the American Metorological Society in Long Beach, California in a special session dedicated to the scientific study of global warming.
Dr. Roy Spencer, a scientist at NASA/Marshall and principal author on the paper, has been monitoring the temperature of layers in the Earth's atmosphere from space. Along with Dr. John Christy of the University of Alabama in Huntsville, Spencer has produced a temperature record spanning 18 years. Acquired from Microwave Sounding Unit (MSU) instruments flying aboard the TIROS series of weather satellites. Their data show temperature variations in the lower troposphere, a region from the surface to about 5 miles into the atmosphere.
"The temperatures we measure from space are actually on a very slight downward trend since 1979 in the lower troposphere. We see major excursions due to volcanic eruptions like Pinatubo, and ocean current phenomena like El Nino, but overall the trend is about 0.05 degrees Celsius per decade cooling," Spencer remarked.
The interesting thing about this data is it is hard and not open to question. The earth's atomosphere is definitely cooling. Combine this with rural temperature records from co2science.com that show a clear cooling trend in most locations and the evidence I have posted that the southern oceans (most of the world's oceans) seem to be cooling and it seems the day of reckoning for the Kyoto sky-is-falling industry is not far off. |
