How did the Maunder minimum relate to the Little Ice Age in Europe?

The Maunder minimum, a period of significantly reduced sunspot activity between 1645 and 1715, coincided with the coldest phase of the Little Ice Age in the Northern Hemisphere.1

During this interval, Europe experienced severe climatic conditions, including the freezing of the Thames River and frequent crop failures. Because low sunspot activity is associated with decreased solar output, some scientists argue that the reduction in available solar radiation contributed to the cooling observed during this time.12

However, the relationship remains a subject of scientific debate. While the timing is suggestive, the physical mechanism linking solar activity to Earth's climate is not fully understood. Furthermore, because cooling episodes occurred in various parts of the world at different times and for different durations, many researchers contend that reduced solar output cannot be the sole cause of the Little Ice Age, noting that factors such as volcanism and changes in atmospheric circulation likely played significant roles.12
