Scientists have successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating -- a new technique that may allow them to locate and date ice that is more than a million years old. This will allow them to reconstruct the climate much farther back into Earth's history and potentially understand the mechanisms that have triggered the planet to shift into and out of ice ages.
