Did Quiet Sun Cause Little Ice Age After All? - ScienceNOW
“There’s tantalizing evidence that [during the Maunder Minimum] the sun may have actually dimmed more than we have thought until now,” Foukal says.
Even so, Foukal concedes that other factors, such as enhanced volcanic activity around the globe, may also have played a role in causing Europe’s Little Ice Age. Meanwhile, the biggest worry to solar physicists—and to society—is that no one knows what caused the sun’s prolonged quiescence in the first place. As far as anybody knows, a repeat of the Maunder Minimum could start within a few years with the next dip in the number of sunspots.
