~24.3 million billion tons of ice, then it will take ~162 THOUSAND years for the entire ice sheet to melt assuming melt rates remain the same. It’s possible that the rate could increase due to positive feedback, but it’s also as equally possible that it decelerates due to negative feedbacks that are ignored in modeling (or not well understood). Even in a worst case scenario, it would take thousands of years for the entire Antarctic ice sheet to melt, and the rate of sea level rise would still be slow enough to mitigate with modern technologies.
