evidence: London: Scientists from the University of Northumbria warned that the Earth could face frosty weather and intense snow storms over the next 30 years as an ominous "solar minimum" grips the planet. [...] These only occur once every 400 years or so and most of the effects will be harmless. Professor Zharkova, however, warned icy spells and wet summers could persist until solar activity picks up again in 2053. She listed recent unusual chills in Canada and Iceland as evidence of the Grand solar Minimum (GSM) already taking hold.
