28 Jul 11 - (Excerpts) - NASA satellite data from the years
2000 through 2011 show the Earth's atmosphere is allowing far more heat
to be released into space than alarmist computer models have predicted,
reports a new study in the peer-reviewed science journal
Remote Sensing.
The study indicates far less future global warming will occur than
United Nations computer models have predicted, and supports prior
studies indicating increases in
atmospheric
carbon dioxide trap far less heat than alarmists
have claimed.
Study co-author Dr. Roy
Spencer, a principal research scientist at the University of Alabama in
Huntsville and U.S. Science Team Leader for the Advanced Microwave Scanning
Radiometer flying on NASA's Aqua satellite, reports that real-world data from
NASA's Terra satellite contradict multiple assumptions fed into alarmist
computer models.
"The satellite observations suggest there is much
more energy lost to space during and after warming than the climate models
show," Spencer said in a July 26 University of Alabama
press release. "There is a huge discrepancy between the data and the
forecasts that is especially big over the oceans."
In addition to finding that
far less heat is being trapped than alarmist computer models have predicted, the
NASA satellite data show the atmosphere begins shedding heat into space long
before United Nations computer models predicted.

"Climate models
get energy balance wrong, make too hot forecasts of global warming,"
says the UA press release.
"Data from
NASA’s Terra satellite shows that when the climate warms, Earth’s
atmosphere is apparently more efficient at releasing energy to space
than models used to forecast climate change have been programmed to
“believe.”
"The previously
unexplained differences between model-based forecasts of rapid
global warming and meteorological data showing a slower rate of
warming have been the source of often contentious debate and
controversy for more than two decades.
"Not only does
the atmosphere release more energy than previously thought, it
starts releasing it earlier in a warming cycle. The models forecast
that the climate should continue to absorb solar energy until a
warming event peaks. Instead, the satellite data shows the climate
system starting to shed energy more than three months before the
typical warming event reaches its peak.
"For this
experiment, the UA Huntsville team used surface temperature data
gathered by the Hadley Climate Research Unit in Great Britain. The
radiant energy data was collected by the Clouds and Earth’s Radiant
Energy System (CERES) instruments aboard NASA’s Terra satellite.
"The six
climate models were chosen from those used by the U.N.’s
Intergovernmental Panel on Climate Change. The UA Huntsville team
used the three models programmed using the greatest sensitivity to
radiative forcing and the three that programmed in the least
sensitivity." |
In short, the central premise of alarmist global warming theory
is that carbon dioxide emissions should be directly and indirectly trapping a
certain amount of heat in the earth's atmosphere and preventing it from escaping
into space.
Real-world measurements, however, show far less heat is being
trapped in the earth's atmosphere than the alarmist computer models predict, and
far more heat is escaping into space than the alarmist computer models predict.

Roy W. Spencer received his Ph.D. in meteorology at the
University of Wisconsin-Madison in 1981. Before becoming a Principal
Research Scientist at the University of Alabama in Huntsville in
2001, he was a Senior Scientist for Climate Studies at NASA’s
Marshall Space Flight Center, where he and Dr. John Christy received
NASA’s Exceptional Scientific Achievement Medal for their global
temperature monitoring work with satellites.
Dr. Spencer’s work with NASA continues as the U.S. Science Team
leader for the Advanced Microwave Scanning Radiometer flying on
NASA’s Aqua satellite. He has provided congressional testimony
several times on the subject of global warming.
Dr. Spencer’s research has been
entirely supported by U.S. government agencies: NASA, NOAA, and DOE. |
