I would not place much emphasis on sunspots.

The sun's activity is in free fall, according to a leading space physicist. But don't expect a little ice age. "Solar activity is declining very fast at the moment," Mike Lockwood, professor of space environmental physics at Reading University, UK, told New Scientist. "We estimate faster than at any time in the last 9300 years."

Lockwood and his colleagues are reassessing the chances of this decline continuing over decades to become the first "grand solar minimum" for four centuries. During a grand minimum the normal 11-year solar cycle is suppressed and the sun has virtually no sunspots for several decades. This summer should have seen a peak in the number of sunspots, but it didn't happen.

But Lockwood says we should not expect a new grand minimum to bring on a new little ice age.Human-induced global warming, he says, is already a more important force in global temperatures than even major solar cycles. "

Solar activity varies about 0.1%; that has little effect.
