Century to millennial-scale temperature variations for the last two thousand years indicated from glacial geologic records of Southern Alaska

Abstract

Comparisons of temperature sensitive climate proxy records with tree-ring, lichen and radiocarbon dated histories from landterminating, non-surging glaciers for the last two millennia from southern Alaska identify summer temperature as a primary driver of glacial expansions. Two major intervals in the Alaskan chronology of glaciation, during the First… (More)
