Theodor Landscheidt, who was a solar physicist and successful predictor of all el nino and la nina events, also predicted the coming of a mini ice age due to solar variations before his death.
He said however the Maunder minimum would be about 2030.
Our long range weather forecaster, Lennox Walker is a Landscheidt adherent.
This is no way means we should not be looking for ways to decrease the levels of CO2 in the atmosphere asap as *after* the Maunder minimum, the planet will start heating up again. If combined with significant CO2 rises, the subsequent increase in temperature might quickly become catastrophic.
