Can sunspots and other solar activity be used to predict long range weather?
Correlations made between solar activity and daily, monthly or seasonal weather are unsubstantiated. No testable physical mechanism exists to explain correlations between sunspots and climate. “Despite much research, no connection between solar variations and weather has ever been unequivocally established. Apparent correlations have almost always faltered when put to critical statistical examination or have failed when tested with different data sets. As a result the subject has been one of continual controversy and debate.
