That could mean a repeat of the Dalton Minimum, which was one of the most extreme weather periods in history. #miniiceage #earth #sun #planet Source: Ī post shared by Bridge News on at 10:00am PSTĪstronomer Tony Phillips has suggested that the sunspot counts could produce one of the “deepest (solar minimums) of the solar system.” Researcher Irina Kitiashvili, who used NASA models, made a similar projection for the current solar cycle, positing that it could “be the weakest of the last 200 years.” These only occur once every 400 years or so. That's because it marks the start of a rare event known as a Grand Solar Minimum, in which energy emitted from the Sun plummets down even more than usual. However, 2020's minimum is going to be a special case. Solar minimums are part of the Sun's natural life cycle and occur once every 11 years. That might not sound a lot but a whole degree fall would have a significant impact on global average temperatures. The average temperatures could drop as much as one degree Celsius in a period lasting about 12 months.
As it further goes into its natural hibernation phase, Earth will experience extremely cold spells which will trigger food shortages across the planet. According to NASA, the Sun will reach its lowest activity in over 200 years in 2020. Scientists have warned that as a result of the Sun’s inactivity, Earth is likely to witness a ‘mini ice age’ that could bring extreme winters and chilly cold storms over the next 30 years. Earth is bracing for a solar minimum: a dormant period in which the Sun radiates less energy or heat at our planet than usual.
