The Coming Modern Grand Solar Minimum

DM

I wrote last week about the coming Grand Solar Minimum, something that will have much more impact on the environment than anything we puny humans can do. It generated a lot of interest from all sides, so it’s time to delve deeper into what we can expect. Starting with the hype: During the last grand solar minimum (GSM), the Maunder Minimum of 1645 to 1715, glaciers advanced, rivers froze, sea ice expanded — in short, the Little Ice Age. Is another one is almost upon us? Probably not. Maunder occurred at the tail end of a bi-millennial cycle. These cycles range between 2,000 and 2,600 years in length and see the Earth first warm, then cool. Gradual cooling had been going on for hundreds of years. Maunder just capped it off. Today we are a few hundred years into the warming phase of the subsequent bi-millennial cycle. Different starting conditions yield different paths. The progressives say that we’re so deep into anthropogenically accelerated climate change that there’s almost no time left to turn things around. Nope, sorry squad members. What we can predict, instead, is an overall temperature reduction of 1 degree Centigrade by the end of the GSM.
