Magnetic Reversal Found in Ice Core

TNRTB Archive - Retained for reference information

A team of European scientists has found additional evidence that Earth is more than 10,000 years old. Ice cores in Antarctica and Greenland show annual layering that indicates the first layers were deposited roughly 800,000 years ago. One objection often raised by those espousing a young-earth view is that the layers were not actually deposited yearly. Detailed isotopic studies of ice-core layers using beryllium reveal evidence of a reversal of Earth’s magnetic field. If the layers were deposited annually, the reversal would date around 780,000 years ago. These results match the dates for a particular magnetic-field reversal found using an independent method relying on sedimentary rocks. Any young-earth model’s explanation would require that very different radioisotope decay rates and ice deposition rates would conspire in such a way as to give the same date. However, the straightforward interpretation—that the reversal occurred roughly 780,000 years ago—finds a natural fit in RTB’s creation model, which asserts that Earth is actually 4.5 billion years old.
