The Year Without a Summer occurred during the Dalton Minimum

Recently, astrophysicist Piers Corbyn forecast that we’re headed into a Little Ice Age. He made that forecast because circulation patterns are beginning to look like the Maunder and Dalton Minimums.

The Dalton Minimum, a period of low solar activity named after English meteorologist John Dalton, lasted from about 1790 to 1830, says this article on Wikipedia.



“Like the Maunder Minimum and Spörer Minimum,” the article continues, “the Dalton Minimum coincided with a period of lower-than-average global temperatures. The Oberlach Station in Germany, for example, experienced a 2.0°c decline over 20 years.”

“The precise cause of the lower-than-average temperatures during this period is not well understood.”

Not well understood? Do you suppose the fact that it was “a period of low solar activity” might have had something to do with it?

The prime reason for that particular cold spike, says Wikipedia, was the colossal eruption of Mount Tambora in Indonesia, one of the two largest eruptions in the past 2000 years, and which caused the Year Without a Summer in 1816.

In other words, the The Year Without a Summer occurred during the Dalton Minimum.

“Recent papers have suggested,” the article continues, “that a rise in volcanism was largely responsible for the cooling trend.”

I contend that the rise in volcanism was triggered by the low sunspot count. With that in mind, I think we should be preparing for ever more volcanic activity as we enter this new sunspot minimum.

“Looking at the Wikipedia chart on the Dalton minimum,” says John, “it appears that yearly sunspot totals were less than 100. So 100 divided by 365 gives you .27 of a sunspot per day.”
