A new study from Lund University in Sweden, published Aug. 17 in Nature Geoscience, has reconstructed solar activity during the last ice age, the last so-called “global maximum” extending from 20,000 to 10,000 years ago. Analysis of trace elements in ice cores in Greenland and from cave formations in China indicates the growth and melting of a thick ice sheet stretching from the Arctic to northern Germany were related to variations in the sun’s UV radiation outpu.
“The study shows an unexpected link between solar activity and climate change. It shows both that changes in solar activity are nothing new and that solar activity influences the climate, especially on a regional level. Understanding these processes helps us to better forecast the climate in certain regions,” said Raimund Muscheler, lecturer in quaternary geology at Lund University and co-author of the study, in a widely cited interview published by LaboratoryEquipment.com .... http://www.wnd.com
