摘要: In the search for a better understanding of dominant mechanisms Earth's climate system, we present study rapid warm transitions into Dansgaard-Oeschger events as seen in ice-cores from Greenland Ice Sheet. We continuous δO-record GRIP core with resolution 5 yrs until 50 kyrs BP and 20 100 BP. These data are compared other high-resolution records, i.e. GISP2 chemistry-record (25 BP) Ca-record (3 BP). All records have been transformed to Meese/Sowers time scale. The separated interstadials stadials, defined by δO records. examine detail events, propose scenario changes taking place different ice during approximately takes. main difference previous studies is much higher sets available BP; (Taylor others, 1997) focused on only YD/PB transition.
