Link Found Between Cold European Winters and Solar Activity
Scientists have long suspected that the Sun’s 11-year cycle influences climate of certain regions on Earth. Yet records of average, seasonal temperatures do not date back far enough to confirm any patterns. Now, armed with a unique proxy, an international team of researchers show that unusually cold winters in Central Europe are related to low solar activity â€“ when sunspot numbers are minimal. The freezing of Germany’s largest river, the Rhine, is the key.
