European scientists warn of conditions that, by 2030, could lead to a decade of winters with freezing temperatures — a “mini ice age” the likes of which hasn’t been seen in 370 years.

Researchers at Northumbria University, led by Professor Valentina Zharkova, used mathematical models to predict solar activity will drop by 60%. The last time this happened was between 1645 and 1715, a period marked by lower-than-average temperatures, the Independent reported.

More testing will be needed, but Zharkova is confident about her outlook.

“Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97%,” she said.

Sound familiar? Former NASA consultant and space shuttle engineer John Casey has been known to voice similar concerns. In fact, he wrote a book called “Dark Winter” in which he warns of crop failures and food riots. He says we’ve been preparing for the wrong calamity.

“We don’t have 10 years,” Casey once told conservative website Newsmax. “We’ve squandered during President Obama’s administration eight years ... and we didn’t have eight years to squander.”
