We have determined the black carbon concentration in Greenland Dye‐3 ice core samples covering the time period from about 3380 to 100 years before present. The average concentration found is 1.53 μg of black carbon per 1 kg of ice. We have found significantly lower black carbon concentrations during the time period from 750 to 100 years before present connected possibly with the Little Ice Age and corresponding changes in atmospheric general circulation patterns and black carbon sources.
