Paper finds Arctic climate & sea ice extent related to solar activity — Paper published by the Danish Meteorological Institute
Study 'finds a remarkable correlation of Arctic sea ice observations over the past 500 years to "the solar cycle length, which is a measure of solar activity. A close correlation (R=0.67) of high significance (0.5 % probability of a chance occurrence) is found between the two patterns, suggesting a link from solar activity to the Arctic Ocean climate." The paper adds to several others demonstrating that Arctic sea ice extent and climate is controlled by natural variations in solar activity, ocean & atmospheric oscillations, winds & storm activity, not man-made CO2.'
