Global Warming Alarmists
Are the Ones Full of Hot Air

THE FRIGID TEMPERATURES that continue
throughout the Northeast and the ice storms that pushed into
the Deep South earlier this week causing mayhem and death on
the interstates failed to faze the global warming alarmists,
some of whom came out of hibernation to write letters to
the editor at several newspapers where my column on the
topic ran a few weeks ago.
One letter writer actually wrote that the colder than usual
weather was further evidence of global warming. While my
previous column was not meant to be a serious thesis on the
topic of global warming, this one is.
What we know is that the earth’s average temperature has
warmed by about 1 degree Fahrenheit over the last century.
The National Academy of Sciences reports on their website:
“This warming has been particularly strong during the last
20 years, and has been accompanied by retreating glaciers,
thinning arctic ice, rising sea levels, lengthening of
growing seasons for some, and earlier arrival of migratory
birds. In addition, several other data support that
conclusion.”
If you stopped reading there—as most of the knee-jerk, junk
scientists do—you’d be terribly misled.
NASA has been monitoring the temperature of the lower layers
of the atmosphere since 1979. Since this encompasses the
same “last 20 years” of the National Academy of Sciences’
report of a “particularly strong” warming trend, certainly
balloon measurements in the atmosphere should support this
postulate.
What the data shows is not warming but cooling: “The lower
[troposphere] data are often cited as evidence against
global warming, because they have as yet failed to show any
warming trend when averaged over the entire Earth. The lower
stratospheric data show a significant cooling trend…In
addition to the recent cooling, large temporary warming
perturbations may be seen in the data due to two major
volcanic eruptions: El Chichon in March 1982, and Mt.
Pinatubo in June 1991.”
This finding is in keeping with those of Dr. S. Fred Singer,
president of the Science and Environmental Policy Project,
who points out, “a study of carbon dioxide and temperatures
over the last 11,000 years that was analyzed in both Science
and Nature in 1999 found that the increase in carbon dioxide
in the atmosphere tends to follow not precede a rise in
temperature.”
“The bulk of the temperature rise in the 20th century took
place before 1940 while most of the carbon dioxide emissions
took place after 1940 and coincided with a slight cooling
between 1940 and 1975.”
Richard S. Lindzen, the Alfred P. Sloan Professor of
meteorology at MIT, in his testimony before a Senate
committee in 2002 agreed, stating, past climate changes were
either “uncorrelated with changes in carbon dioxide or were
characterized by temperature changes which preceded changes
in carbon dioxide [levels] by hundreds or thousands of
years.”
So what has caused the “warming” over the last century and
other warming-related phenomenon such as the shrinking polar
ice caps? To many scientists, it’s rather obvious.
In December 2001, a story appeared on ABC News.com. Entitled
“Red Planet Warming,” it reported that high resolution
images taken by NASA’s Mars Global Surveyor showed that the
levels of frozen water and carbon dioxide in Mars’s polar
ice caps dwindled dramatically—by more than 10 feet over a
single Martian year (equivalent to about two earth years).
Since there aren’t any people on Mars, it’s difficult to pin
the blame for Mars’s warming on human activity relating to
the combustion of fossil fuels.
The culprit is “solar warming”—a periodic increase in the
sun’s output of energy. That would explain why the surface
of our planet has grown warmer. And there’s nothing we can
do about it.
Two years ago, Science published a study based on
tree ring analysis that demonstrated similarities between
increases in global temperature the last century and the
Medieval Warm Period—a period lasting from 1330 AD to 1600
AD in which similar increases in temperature occurred. For
those of you who are world-history challenged, that was
before the invention of the internal combustion engine and
the SUV.
Commenting on the study, Edward Cook of the Lamont-Doherty
Earth Observatory said, “We don't use this as a refutation
of greenhouse warming, but it does show that there are
processes within the Earth's natural climate system that
produce large changes that might be viewed as comparable to
what we have seen in the 20th century.”
In other words, the global warming alarmists—not this
journalist—are the ones filled with hot air. n
