An Ice Age happens when the Earth’s surface and atmosphere suffer a long period of reduced temperature.
The last one occurred millions of years ago but global warming theories have suggested it could return.
And the latest weather predictions for this Christmas suggest another Ice Age is around the corner.
Published by YouTube channel MrMBB333, a series of maps show large areas of the US expected to be covered in snow on Christmas Eve.
The host says: “There’s that moisture going up into that low-pressure system.
“On Christmas Eve, look at all the snow through central Illinois.
“And there’s going to be a line of freezing rain.
“We’re talking multiple inches, at least an inch per hour.”
“It could possibly be a record-setting blizzard”
And it does not end on December 24 as the weather only gets worse on Christmas day.
“Look for a huge blizzard,” the host adds.
“It could possibly be a record-setting blizzard.
“If this is heavy snow, like they saw in the Carolinas, it puts a lot of weight on trees and power lines.
“That’s what creates the power outages.”
This footage was only published today but viewers have already been sent into frenzy by the predictions.
“Stock up now while there’s plenty to get,” one said.
Another commented: “You have been warned.”
While a third made a terrifying claim.
“Looks like the chemtrails are creating the next ice age,” they said.
This is not the first time the big freeze has been predicted, though.
NASA predicted the next Ice Age if the sun continues to remain dead.
And a “mini Ice Age” is expected to hit Britain.
