Researchers report synchronized cosmogenic radionuclide and paleoclimate records that show how a period of relative warmth in Greenland around 41,000 years ago occurred in phase with mild winters at the Black Sea, and that enhanced precipitation and warm lake temperatures followed with a lag time of around 190 years; the results suggest that the lag in climate effects may be due to a time-transgressive thermal adjustment of the ocean interior, according to the authors.
