Guide to terminology used in paleoclimate studies of the last 150,000 years

“Event”, Stages	Estimated age (Calendar years)
Holocene	~10 Kyr to Present
Holocene maximum warming (also referred to as “climatic optimum”)	~4.5 to 6 Kyr (Europe) 10 to 6 Kyr (Southern Hemishphere)
Last deglaciation	~18 to 10 Kyr
Termination I	~14 Kyr
Younger drayas	~12.7 to 11.5 Kyr
Antarctic cold reversal	14 to 13 Kyr
Bolling-Allerod warm period	14.5 to 13 Kyr
Last Glacial	~74 to 14 Kyr
LGM (Last Glacial Maximum)	~25 to 18 Kyr
Last interglacial peak	~124 Kyr
Termination II	~130 Kyr
Eemian/MIS Stage 5e	~128 to 118 Kyr
Heinrich events	Peaks of ice-rafted detritus in marine sediments, ~7 to 10 Kyr time scale.
Dansgaard-Oeschger events	Warm-cold oscillations determined from ice cores with duration ~2 to 3 Kyr
Bond Cycles	A quasi-cycle during the last Ice age whose period is equal to the time between successive Heinrich events.
Terminations	Periods of rapid deglaciations
