16...C Rapid Temperature Variation in Central Greenland 70,000 Years Ago.

Deals with a study which presented a reconstruction of the surface temperature change in Central Greenland during Dansgaard-Oeschger (DO), based on measurements of nitrogen isotopes on the GRIP ice core. Characteristics of the DO events; Two ways by which the coefficient that relates the oxygen isotopic composition of water and surface temperature can be derived; Disagreement between the two methods.
