English: From the Vostok and EPICA (Antarctica) and NGRIP (Greenland) ice cores: d-o-18, last 140kyr.
d-O-18 is a proxy for temperature: more negative is colder; the period from 20 to 10 kyr shows the rise in temperature at the end of the last ice age. Note the Dansgaard-Oeschger events visible in the NGRIP core but barely, if at all, in the Antarctic cores. The period around 120 kyr is the previous interglacial; before that (140 kyr) is the previous glacial.
Horizontal axis: years before present (before 1950?). Vertical axis: delta-O-18.
Note that the image is mislabelled/misnamed, the red graph shows NGRIP, not GRIP data (the red graph in this image corresponds to the green graph in File:Epica-vostok-grip-ngrip-o18.png).
