This is a really good article everyone should read:
One pertinent excerpt:
“Professor Valentina Zharkova, a mathematician and PhD. astrophysicist has been studying the planet’s cycles for many years. In 2015, she predicted a new “minimum” or mini ice age would start around five years from that time, based on the known 400 year solar cycle.
Zharkova recently presented her findings on Climate and the Solar Magnetic Field hypothesis at the Global Warming Policy Foundation in October, 2018.
Using reported “eye observations” from the 13th and 14th centuries Professor Zharkova and her team ran calculations up to today. Then they pushed another 1200 years forward and 800 years backwards.
Their generated charts clearly matched all of the great climate change events across that time. The climate events include Minimums and warm periods.
At that time, Professor Zharkova and others predicted there could soon be a mini ice age lasting 40 to 70 years. Now, with almost 5 more years of new information and study, actual observations, and the speed of change, they say this ice age may last 350 to 400 years.”
