The data for Greenland ice cores are much less extensive then for Antarctica.

For the last 50 thousand years though, when Antarctica chills, Greenland freezes.

Apparently.

There does seem to be a phase shift evident at times.

Ice Core Data for Antarctic and Arctic (climatedata.info)

Arctic

Whilst the Antarctic is a continent, the only major area of land in the Arctic covered with snow is Greenland. There have been several ice cores drilled in Greenland but these core do not go as deep as those in the Antarctic. Figure 7 shows temperature calculated for the GISP2 Greenland ice core in comparison to the Vostok Antarctic ice core.
