Quiet Sun = Ice Age?

Dana Longcope, a solar physicist at MSU, said the sun usually operates on an 11-year cycle with maximum activity occurring in the middle of the cycle. The last cycle reached its peak in 2001 and is believed to be just ending now, Longcope said. The next cycle is just beginning and is expected to reach its peak sometime around 2012. But so far nothing is happening. “It’s a dead face,” Tsuneta said of the sun’s appearance.

In the past, they observed that the sun once went 50 years without producing sunspots. That period coincided with a little ice age on Earth that lasted from 1650 to 1700.

Glance at the chart above and understand that we really still have no way of predicting what the sun will do, and consequently all of our efforts to warm up the planet might be wasted if the Sun stays quiet, as it has done not too long ago.
