Summary
Comparison of temperature proxies for ice cores from Antarctica and Greenland for 140,000 years. Greenland ice cores use delta 18O, while Antarctic ice cores use delta 2H. Note the <a href="https://en.wikipedia.org/wiki/Dansgaard-Oeschger_event" class="extiw" title="en:Dansgaard-Oeschger event">en:Dansgaard-Oeschger events</a> in the Greenland ice core between 20,000 and 110,000 years ago, which barely register (if at all) in the corresponding Antarctic record. GRIP and NGRIP data is on ss09sea timescale, Vostok uses GT4, and EPICA uses EDC2.
