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.
