High-resolution accelerator-mass-spectrometer radiocarbon dating was performed on late-glacial macrofossils in lake sediments from Kodiak Island, Alaska, and on shells in marine sediments from southwest Sweden. In both records, a dramatic drop in radiocarbon ages equivalent to a rise in the atmospheric ¹⁴C by 70 coincides with the beginning of the cold period at 11 000 yr B.P. (¹⁴C age). Thus, our results show that a close correlation between climatic records around the globe is possible by using a global signature of changes in atmospheric ¹⁴C content.
