My friend writes: Also, the 10-12 year cycle of sunspots does not have a significant effect on climate. In fact, the climate scientists desperately trying to find other causes of global warming investigated them thoroughly, studies show that the change in solar insolation to be roughly one and a half orders of magnitude smaller than needed to be comparable to the current temperature changes. The temperature decrease from even the little ice age was less than a third of the temperature increase we've already experienced, and you know we're in for another three times that best case scenario. A little ice age now would be a wonderful coincidence, but would hardly change the dire outlook as the heating well surpasses it. That fortuitous event would only effect the price we put on carbon by ~1/31/3.
