Satellites Show No Acceleration In Global Warming For 23 Years

Technocrats will ignore any data that presents a contrary case against their own pre-conceived ideas and assumptions. In this case,  another solid report from university scientists with funding from the Department of Energy! ⁃ TN Editor

Global warming has not accelerated temperature rise in the bulk atmosphere in more than two decades, according to a new study funded by the Department of Energy.

University of Alabama-Huntsville climate scientists John Christy and Richard McNider found that by removing the climate effects of volcanic eruptions early on in the satellite temperature record it showed virtually no change in the rate of warming since the early 1990s.

“We indicated 23 years ago — in our 1994 Nature article — that climate models had the atmosphere’s sensitivity to CO2 much too high,” Christy said in a statement. “This recent paper bolsters that conclusion.”

Christy and McNider found the rate of warming has been 0.096 degrees Celsius per decade after “the removal of volcanic cooling in the early part of the record,” which “is essentially the same value we determined in 1994 … using only 15 years of data.”

The study is sure to be contentious. Christy has argued for years that climate models exaggerate global warming in the bulk atmosphere, which satellites have monitored since the late 1970s.

Christy, a noted skeptic of catastrophic man-made global warming, said his results reinforce his claim that climate models predict too much warming in the troposphere, the lowest five miles of the atmosphere. Models are too sensitive to increases in carbon dioxide concentrations in the atmosphere, he said.

“From our observations we calculated that value as 1.1 C (almost 2° Fahrenheit), while climate models estimate that value as 2.3 C (about 4.1° F),” Christy said.

While many scientists have acknowledged the mismatch between model predictions and actual temperature observations, few have really challenged the validity of the models themselves.

A recent study led by Lawrence Livermore National Laboratory climate scientist Ben Santer found that while the models ran hot, the “overestimation” was “partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.”

Christy’s removal of volcanic-driven cooling from satellite temperature data could also draw scrutiny. The study also removed El Nino and La Nina cycles, which are particularly pronounced in satellite records, but those cycles largely canceled each other out, the co-authors said.
