Scandinavian eskers, global climatic relationships, and solar forcing

Abstract

The morphology of a number of eskers in Sweden formed during the down-wasting of the last Scandinavian ice sheet about 11,000 to 10,000 calendar years ago shows a subdivision into centres representing periods of 1,3-6 and 10-11 years. It is proposed that these periods correspond to the summer/winter seasons, the El NiÔo - Southern Ocean (ENSO) cycle, and the sunspot cycle, respectively. If this is correct, the implication is a more global climatic relationship than earlier realised
