Mid-Deglacial Cooling: The Younger Dryas
q The mid-deglacial pause in ice
melting was accompanied by a
brief climate osscilation in records
near the subpolar North Atlantic
Ocean.
q Temperature in this region has
warmed part of the way toward
interglacial levels, but this reversal
brought back almost full glacial
cold.
q Because an Arctic plant called
“Dryas” arrived during this
episode, this mid-deglacial cooling
is called “the Younger Dryas”
event.
