Sceince of dating events using ice
In the sequence of events in the creation-Flood Ice Age model, at the end of deglaciation, the Ice Age was effectively over. The Greenland and Antarctica ice sheets are remnants left over from the post-Flood Ice Age (figures 12.1 and 12.2).
They were protected from melting by their location in the polar latitudes and by the high altitude of the ice deposited during the Ice Age.
The method of counting annual layers only works with the high accumulation Greenland ice sheet.
From incredible winter sports to the dazzling aurora borealis, we’ll be exploring all sorts of exciting seasonal science with hands-on fun every Saturday in December.The claimed 110,000 annual layers in the GISP2 ice core to near the bottom of the Greenland ice sheet is not a straightforward deduction.The annual layers, indeed, show up well near the top of the ice sheet.From the top of the Greenland ice sheet, glaciologists further claim that they can count the annual layers downward, like counting the rings in a tree to determine its age.They arrive at 110,000 years for the top 90 percent of the ice sheet.1 Is their claim justified?
Some scientists believe that if the ice somehow disappeared, it probably would not return in the present climate. Many ice cores have been drilled deep into both the Antarctica and Greenland ice sheets since the 1960s (see figures 12.1 and 12.2).
