"If you're trying to model an ice sheet, the single most important input is ice thickness," said Prof Jonathan Bamber. "Why's that? Because velocity is proportional to the fourth power of thickness. So differences in thickness make for huge differences in the velocity of the ice in our models; and to things like thermodynamics, because thick ice is warmer than thin ice, and so on," the Bristol University, UK, glaciologist told BBC News."
