Professor Zharkova studies sun cycles…shorter-run cycles and longer-run cycles. I think she has made very clear connections over long periods of time between the different types of energy coming from the sun and changes in earth’s climate. She predicted that cooling would begin in 2020 and continue for about 30 years. You can read about her research via the links below.
