Sun Responsible for Global Warming
As Reported on NewsMax

Two new reports cast doubt on the manmade global warming theory and
instead point to another cause for the recent warming of Earth to
changes in the sun.

One report from National Geographic News asserts, "Simultaneous
warming on Earth and Mars suggests that our planet's recent climate
changes have a natural and not a human-induced cause, according to one
scientist's controversial theory.

Data from NASA's Mars Global Surveyor and Odyssey mission in 2005
disclosed that the carbon dioxide "ice caps near Mars' south pole had
been shrinking for three consecutive summers.

Habibullo Abdussamatov, head of the Pulkovo Astronomical Observatory
in Russia, says the shrinking provides evidence that the current
warming on Earth is being caused by changes in the sun, according to
the National Geographic article.

"The long-term increase in solar irradiance is heating both Earth
and Mars, he said. "Manmade greenhouse warming has made a small
contribution to the warming seen on Earth in recent years but it
cannot compete with the increase in solar irradiance.

The other report offers a mechanism behind the changes in the sun
variations in its magnetic field.

Compiled by scientists at the Danish National Space Center, it
maintains that the Earth's climate is strongly influenced by cosmic
rays from exploded stars.

The cosmic rays help make ordinary clouds, and high levels of rays and
cloudiness cool the planet, while lower levels of radiation lead to
milder temperatures, according to the Danish report, which is cited by
Marc Morano, communications director for the U.S. Senate Committee on
Environment & Public Works, on the committee's Web site.

"Cosmic ray intensities and therefore cloudiness keep changing because
the sun's magnetic field varies in its ability to repel cosmic rays
coming from the galaxy before they reach the Earth, the Danish report
by Henrik Svensmark, head of the Space Center, explains.

Whenever the sun's magnetic field was weak, cosmic ray intensities
were high and the climate cooled, most recently in the little ice age
that climaxed 300 years ago.

Several scientists cited in the report believe that changes in the
Earth's climate are linked to "the journey of the sun and the Earth
through the Milky Way Galaxy. They blame the icehouse episodes on
encounters with bright spiral arms, where cosmic rays are most
intense.

"... according to one scientist's controversial theory."
One out of how many?

Please continue your thought. One scientist cannot be right
because....

One scientist *can* be right but if that scientist's opinion is
anathema to the general consensus of the related field - in this case
climatology - then it would probably not be a good idea to formulate
public policy around the lone figure.

For the record: I don't think climatologists have an adequate model
around which to construct policy. Global warming - although *very*
popular in this group - still requires a great deal of work before we
can adequately assess the situation. Are we dealing with a minor
annoyance or a catastrophe? I'll agree to higher costs in order to
avoid the latter. The former? Not so much.
