Sunspots Are Back To Zero

At Watt’s Up With That, David Archibald marks the occasion by posting updates a few graphs relating to solar activity.  The upshot — solar activity is low and seems to be bent on remaining low.  That matters because low sunspot activity historically has corresponded with lower than average global temperatures.  In particular, Archuleta spots some similarities to the Dalton Minimum, a period of global cooling lasting from about 1790 to 1830.  As humankind learned back then, cold weather is far worse for us than warm weather.
