17 Sep 08 – Warming and cooling cycles are more
directly tied in with astronomical influences than they are with
human-caused carbon dioxide (CO2) emissions, some scientists now say.
”An examination of warming and cooling trends over the last 400 years
shows an “almost exact correlation” between all of the known climate
changes that have occurred and solar energy transmitted to the Earth,
while showing “no correlation at all with CO2,” Don J. Easterbrook, a
geologist with Western Washington University in Bellingham, Wash., told
CNSNews.com.
Easterbrook has identified about 30 warming and cooling cycles reaching
back over the past several hundred years.
“Only one in 30 shows any correlation with CO2,” he said. “So if you’re
a baseball player with 30 at bats, that’s not a very good average.”
”The ice core records also show that after the last Ice Age ended,
temperatures rose for about 800 years before CO2 increased, Easterbrook
pointed out in a recent paper. This demonstrates that “climatic warming
causes CO2 to rise, not vice-versa.
”Meanwhile, other scientists are beginning to attach themselves to the
idea that the sun, not mankind, is primarily responsible for driving
global warming.
”Dr. Bruce West, the chief scientist of the U.S. Army Research Office’s
mathematical and information science directorate, sees a strong link
between the dynamics of the sun and the Earth’s ecosystem.
“The Sun could account for as much as 69 percent of the increase in
Earth’s average temperature, says West
“Although it was long assumed that the sun was a constant star, one that
did not experience any variability in its irradiance, this is not the
case, Fred Singer, an atmospheric and space physicist, pointed out in an
interview.
”Solar variability – fluctuations in the sun’s radiation – directly
affects climate change on Earth, in his estimation.
”Willie Soon, a climate scientist based in Massachusetts, sees a mix of
astronomical influences that include the sun and other heavenly bodies.
“For me what works is to look at the powerful phenomenon attached to
how the earth goes around the sun. Very slight changes [in the orbit]
can lead to changes in the seasons.”
”Soon credits a mathematician named Milutin Milankovic from Yugoslavia
(now Serbia) who formulated the “orbital theory of climate change” back
during the World War II era for offering up an explanation that remains
salient and relevant to this day.
Yes. As I said in Not by Fire but by Ice, I think the Milankovic
cycle controls our climate.
“So the way this theory works, we do not look at the energy of the sun
itself,” Soon said.
“Instead we look at the way our earth is being pulled and tugged by
bigger planets, including the sun and the most massive gas giants. This
is how our orbit is changing. Seasons can be changed slightly and yet
significantly by orbits being pulled and tucked.”
As it turns out, this warming trend could be over anyway, says
Easterbrook, the geologist from Washington State. A slight cooling
period that began to take hold in 1998 could endure for the next 30
years, he forecasts.
“It’s practically slam dunk that we are in for about 30 years of global
cooling,” he said. Not something you will read about in the media.”
