Cold snaps so severe they could threaten food shortages and plummeting temperatures are a very real possibility over the next 30 years, an expert claims.
With the Sun entering a natural “hibernation period” or solar minimum in which it projects less heat at the Earth there could be frostier weather and heavy snow storms.
Scientist Valentina Zharkova, of Northumbria University, said average temperatures could drop by 1C in 2020 and last up to a year – while resulting in wet and cold summers.
And the minimum was the cause for Canada’s recent -50C, she claims.
