Comparative Ice Core Evidence

Caption

(A) Decadal averages of O-18 isotopes from low-latitude, high-elevation ice fields are combined for the last 2,000 years. The number of cores contributing to various parts of the 2,000-year record is shown. (B and C) Also shown are the composites for four Tibetan (B) and three Andean (C) cores. (D) These cores are compared to the Northern Hemisphere meteorological observations (red) back to A.D. 1860 (50) and a multiproxy history (blue) back to approximately 200 A.D.(51).
