That could affect weather on Earth because low solar activity has been linked to low global temperatures in the past.

Three studies, presented at a meeting of the American Astronomical Society’s solar physics division, all point towards declining sunspot activity into the next decade.

Between 1645 and 1715 almost no sunspots were observed, a solar period which came to be called the Maunder Minimum. During those decades Europe suffered frequent unusually harsh winters, and the time was later termed the Little Ice Age.
