Earth beneath ice sheet key to predicting sea level rise from warming climate

Findings from an international team of researchers, including those from Penn State, suggest that Earth's natural forces could substantially reduce the melting of the West Antarctic Ice Sheet and its impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current rising trajectory, Antarctic ice loss could lead to more sea level rise in the future than previously thought, according to the researchers.
