"Three independent studies of the sun's insides, surface, and upper atmosphere all predict that the next solar cycle will be significantly delayed—if it happens at all. Normally, the next cycle would be expected to start roughly around 2020.[---]
The combined data indicate that we may soon be headed into what's known as a grand minimum, a period of unusually low solar activity.
The predicted solar "sleep" is being compared to the last grand minimum on record, which occurred between 1645 and 1715.
Known as the Maunder Minimum, the roughly 70-year period coincided with the coldest spell of the Little Ice Age, when European canals regularly froze solid and Alpine glaciers encroached on mountain villages."
"...even if there is a climate link, Pesnell doesn't think another grand minimum is likely to trigger a cold snap.[---]
"With what's happening in current times—we've added considerable amounts of carbon dioxide and methane and other greenhouse gases to the atmosphere," said Pesnell, who wasn't involved in the suite of new sun studies.
"I don't think you'd see the same cooling effects today if the sun went into another Maunder Minimum-type behavior.""
"Taken together, the three lines of evidence strongly hint that Solar Cycle 25 may be a bust..."Whew!!
