Why Was the Maunder Minimum So Cold?

The Maunder Minimum occurred within the Little Ice Age, a long period of lower-than-average European temperatures. The reduced solar activity may have contributed to the climatic cooling, although the cooling began before the solar minimum and its primary cause is believed to be volcanic activity.

Why was the Little Ice Age so cold?

The Little Ice Age was caused by the cooling effect of massive volcanic eruptions, and sustained by changes in Arctic ice cover, scientists conclude. ... They say a series of eruptions just before 1300 lowered Arctic temperatures enough for ice sheets to expand.

What was the weather like during the Maunder Minimum?

From 1650 to 1710, temperatures across much of the Northern Hemisphere plunged when the Sun entered a quiet phase now called the Maunder Minimum. During this period, very few sunspots appeared on the surface of the Sun, and the overall brightness of the Sun decreased slightly.
