Ente 1645 and 1715, Earth experienced a period called the Maunder minimum . The number of sunspots – and therefore the magnetic field of the Sun and all forms of activity resulting – is significantly reduced. A phenomenon that could happen around 2030.
At that time, the winters were so cold that the Thames was frozen. But a new ice age is it still possible? To believe a study published by Royal Astronomical Society , scientists estimate that within five years, the Earth could be hit again by a mini ice period causing very cold winters.
Last year, NASA had already made similar predictions, saying the number of sunspots fell sharply since 2011 and solar flares are less and less important and increasingly rare.
