STUDY: Satellites Show No Acceleration In Global Warming For 23 Years
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.
