So the Maunder Minimum didn't happen?
Correlation is not causation. But it doesn't even correlate well. From wikipedia:
Note that the term "Little Ice Age" applied to the Maunder minimum is something of a misnomer as it implies a period of unremitting cold (and on a global scale), which is not the case. For example, the coldest winter in the Central England Temperature record is 1683-4, but the winter just 2 years later (both in the middle of the Maunder minimum) was the fifth warmest in the whole 350-year CET record. Furthermore, summers during the Maunder minimum were not significantly different to those seen in subsequent years. The drop in global average temperatures in paleoclimate reconstructions at the start of the Little Ice Age was between about 1560 and 1600, whereas the Maunder minimum began almost 50 years later.And note the "and on a global scale". The "Little Ice Age" was not global. While Northern Europe and the US had very cold winters, southern Europe, Canada and Greenland did not.
