Antarctic and Greenland Ice Core Dates Match

Studies of ice cores affirm the antiquity of Earth and pose a serious challenge to young-earth models. Layers in ice cores (cylinders of ice removed from an ice sheet) can be used to determine ages if the layers are deposited annually. Assuming annual layering, high-resolution ice cores from Greenland and Antarctica give ages in the hundreds of thousands of years (indicating Earth is at least that old). Recent work conclusively demonstrates that events occurring on century and millennial timescales in both cores correlate with each other. Furthermore, the cores show variability matching periodicities in Earth’s orbit that occur on millennial timescales. These results corroborate and strengthen RTB’s old-earth model but present an awkward fit—if they can be fit at all—in young-earth models.
