This paper Solar forcing on the ice winter severity index in the western Baltic region, was published yesterday in the Journal of Atmospheric and Solar-Terrestrial Physics. It suggests that the winter severity index over the past 600 years in the Baltic region of the Arctic is “strongly modulated” by solar activity over periods as short as one decade, or in other words, the 11 year sunspot cycle. Me, I’m not so sure, because this would likely have been observed before if the correlation were so strong. OTOH, there’s the recent story about the ice skating festivals on canals showing a correlation.
