Scientists warn that The Grand Solar Minimum could lead to a global food shortage.
Experts warn that a 'mini ice age' could grip the planet in the next 30 years and see temperatures in the coldest areas plummet to -50C, claiming the sun could enter a natural "hibernation period" also known as a solar minimum where it projects less heat, bringing frostier weather conditions and heavy snow.
Valentina Zharkova, a scientist at Northumbria University who has published multiple papers on solar minimums, said average temperatures could drop by 1C in 2020.
This might sound insignificant, but a degree difference can make a significant impact on global weathers and temperatures, leading to wet and cold summers.
Solar minimums are completely normal and happen in the sun's life cycle every 11 years. However, this year's minimum is predicted to be especially cold as the energy emitted from the sun will dip more than usual.
A Grand Solar Minimum occurs every 400 years and wet and cold weather is expected to continue right up until 2053.
Professor Zharkova pointed to the unusually wintry weather in Iceland and Canada as evidence that the minimum was already taking place.
The professor said: "The Sun is approaching a hibernation period.
"Less sunspots will be formed on the solar surface and thus less energy and radiation will be emitted towards the planets and the Earth.
"The reduction in temperature will result in cold weathers on Earth, wet and cold summers, cold and wet winters.
"We will possibly get big frosts as is happening now in Canada where they see [temperatures] of -50C."
