Solar grand minima linked to cooling period in Europe

This is interesting. A quick cooling in Europe together with an increase in humidity and particularly in windiness was found to coincide with a long-term reduction in solar activity 2800 years ago during something called the “Homeric minimum”. The paper … Continue reading
