A surprising discovery in the field of glaciology has been making some waves in the scientific community lately. It could help us better understand the ice that cover the South Pole and thus better model how it could react to a warming planet.
The study shows data on how ice melts and re-freezes extensively at the base of the Antarctic ice sheet, creating new ice bottom-up, which isn't how ice is supposed to behave according to current models. "In places, this deeply buried add-on layer is hundreds of metres thick and represents about half of the entire ice column". Read more about it at the NYT and BBC.
