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.
The new findings are extremely important and should dramatically alter the
global warming debate.
Scientists on all sides of the global warming debate are in general
agreement about how much heat is being directly trapped by human emissions
of carbon dioxide (the answer is “not much”). However, the single most
important issue in the global warming debate is whether carbon dioxide
emissions will indirectly trap far more heat by causing large increases in
atmospheric humidity and cirrus clouds. Alarmist computer models assume
human carbon dioxide emissions indirectly cause substantial increases in
atmospheric humidity and cirrus clouds (each of which are very effective at
trapping heat), but real-world data have long shown that carbon dioxide
emissions are not causing as much atmospheric humidity and cirrus clouds as
the alarmist computer models have predicted.
The new NASA Terra satellite data are consistent with long-term NOAA and
NASA data indicating atmospheric humidity and cirrus clouds are not
increasing in the manner predicted by alarmist computer models. The Terra
satellite data also support data collected by NASA’s ERBS satellite showing
far more longwave radiation (and thus, heat) escaped into space between
1985 and 1999 than alarmist computer models had predicted. Together, the
NASA ERBS and Terra satellite data show that for 25 years and counting,
carbon dioxide emissions have directly and indirectly trapped far less heat
than alarmist computer models have predicted.
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.
When objective NASA satellite data, reported in a peer-reviewed scientific
journal, show a “huge discrepancy” between alarmist climate models and
real-world facts, climate scientists, the media and our elected officials
would be wise to take notice. Whether or not they do so will tell us a great
deal about how honest the purveyors of global warming alarmism truly are.
