After a relatively stable MIS 2
period, Termination 1 is marked by a rapid 13C depletion over the
Glacial - Bolling transition followed by a return to
somewhat heavier values during the Younger Dryas, similar to earlier observations [1].
Such as
glacial periods have happened before in the past, many species must be
somewhat attuned to surviving it, but no doubt many species will perish.
