Over this period, the onset of seven major millennial-scale warmings in Antarctica preceded the onset of Greenland warmings by 1500 to 3000 years. In general, Antarctic temperatures increased gradually while Greenland temperatures were decreasing or constant, and the termination of Antarctic warming was apparently coincident with the onset of rapid warming in Greenland. This pattern provides further evidence for the operation of a bipolar see-saw in air temperatures and an oceanic teleconnection between the hemispheres on millennial time scales.","pubRank":"1"}],"site":[{"NOAASiteId":"19973","siteName":"GRIP","siteCode":null,"mappable":"Y","locationName":"Continent>North
