Check the Thermostat!

While we all argue about man's impact on the climate (my most recent take here), why isn't anyone checking the thermostat?

The New
Scientist report, along with other scientific assessments warning of
global cooling, also come as a blow to the campaign -- led by David
Suzuki and one of the directors of his foundation -- to portray all who
raise doubts about climate change theory -- so-called skeptics -- as
pawns of corporate PR thugs manipulating opinion. If the Suzuki claim
is true, then the tentacles of Exxon-Mobil reach deeper into science
than anyone has so far imagined.

Dramatic global temperature fluctuations, as New Scientist
reports, are the norm. A Little Ice Age struck Europe in the 17th
century. New Yorkers once walked from Manhattan to Staten Island across
a frozen harbour. About 200 years earlier, New Scientist reminds us, a
sharp downturn in temperatures turned fertile Greenland into Arctic

These and other temperature swings corresponded with changing
solar activity. "It's a boom-bust system, and I expect a crash soon,"
says Nigel Weiss, a solar physicist at the University of Cambridge.
Scientists cannot say precisely how big the coming cooling will be, but
it could at minimum be enough to offset the current theoretical impact
of man-made global warming. Sam Solanki, of the Max Planck Institute
for Solar System Research in Germany, says declining solar activity
could drop global temperatures by 0.2 degrees Celsius. "It might not
sound like much," says New Scientist writer Stuart Clark, "but this
temperature reversal would be as big as the most optimistic estimate of
the results of restricting greenhouse-gas emissions until 2050 in line
with the Kyoto protocol."

It turns out that while we may be encountering some of the highest temperatures in a couple of centuries, the sun's output is also at its highest point in centuries:
