Coronavirus. COVIDiots. Murder Hornets and the latest is that the sun has been reported to have a “very deep” solar minimum.
Astronomer Dr. Tony Phillips says the current lack of sunspot counts suggests the current solar minimum is one of the ‘deepest’ of the past century.
A sunspot is an area of magnetic activity on the surface of the sun and they play a big part in the sun’s activity.
NASA first recorded no activity on the sun last summer and it is thought to have continued to be without sunspots. Solar minimums usually consist of 12 months of little sunspot activity.
The idea of solar minimums affecting life on Earth is an on-going debate with some scientists believing it can affect the weather and earthquakes. Others argue it has little impact on the planet.
Some scientists have linked previous solar minimums to dramatic drops in Earth’s temperature, including causing what was known as the “little ice age” in the 1600s. Some are afraid it may happen again.
Valentina Zharkova, a professor of mathematics at Northumbria University said ,
“Solar activity will fall by 60 percent during the 2030s to conditions last seen during the ‘mini ice age’ that began in 1645.”
In the 2011 research paper Influence of Solar Cycles on Earthquakes produced by M. Tavares, linked the solar cycle to earthquakes and that there were fewer of them during solar minimum.
The earthquakes analyzed during two grand solar minima, the Maunder (1645-1720) and the Dalton (1790-1820) showed a decrease in the number of earthquakes and the solar activity. After the last [grand] minima (Dalton) the earthquakes pattern increased with solar maxima.
NASA scientists fear it could be a repeat of the Dalton Minimum, which happened between 1790 and 1830, leading to periods of brutal cold, crop loss, famine and powerful volcanic eruptions.
Temperatures plummeted by up to 2 degrees Celsius (35.6 degrees Fahrenheit) over 20 years, devastating the world’s food production.
On April 10, 1815, the second-largest volcanic eruption in 2,000 years happened at Mount Tambora in Indonesia, killing 71,000 people.
It led to the so-called Year Without a Summer in 1816 when there was snow in July. It was also nicknamed
“Eighteen hundred and froze to death”
