New paper finds solar activity may influence Arctic sea ice, less ice during Medieval & Roman Warm Periods – Published in Palaeogeography, Palaeoclimatology, Palaeoecology
Study reconstructs Arctic sea ice near West Greenland over the past 5,000 years and finds that solar activity "may be an important contributor to the sea-ice changes." The paper shows Total Solar Irradiance [TSI] at the end of the 20th century was at the highest levels of the past 5,000 years, and a correspondence between solar activity and Arctic sea ice concentration.
