1 Jul 08 - "The level of activity on
the Sun will significantly diminish sometime in the next decade and
remain low for about 20 - 30 years," said Ian Wilson, lead author of a
study appearing in the June issue of PASA, Publications of the
Astronomical Society of Australia.

A 2005
prediction of solar activity. The sunspot number
should now stand close to 100, instead it is zero. |
The result is a strong, rapid pulse of global cooling,
said Wilson. "On each occasion that the Sun has done this in the past
the World’s mean temperature has dropped by ~ 1 - 2 C.”
"A 2 C drop would be twice as large as all the warming the earth has
experienced since the start of the industrial era, and would be
significant enough to impact global agriculture output."
We're talking about a Little Ice Age here.
The study identified a "spin-orbit
coupling" affecting the rotation rate of the sun. That rotation, in
turn, is linked to the intensity of the solar cycle and climate changes
here on Earth.
I mention this 178.7-year cycle in "Not by Fire but by Ice" -
and say that the next beat of the cycle is due - except that I
refer to it as the solar retrograde cycle.

Earlier this year, astronomers from around the
world noted that solar activity was suspiciously low. Some began
predicting global cooling at that time.

Two months ago, a team of German climatologists forecast that,
due to "natural effects", global warming would halt for up to 15 years.
