The sun has reached a milestone not seen for nearly 100 years: an entire month has passed without a single visible sunspot being noted.

The event is significant as many climatologists now believe solar magnetic activity – which determines the number of sunspots—is an influencing factor for climate on earth.
. Sunspot data has been collected since 1749.
In the past 1000 years, three previous such events—the Dalton, Maunder, and Spörer Minimums, have all led to rapid cooling. One was large enough to be called a “mini ice age”.
