Question

If all the glaciers and ice caps melt, sea level will increase by _____________, but by the end of 2100, we estimate ____________ of sea level rise.

Answer 1

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly . but in 2100 Global sea levels are predicted to rise by 20-60 mm, and possibly up to 1 metre. This is mostly from glacier melt and thermal expansion of the oceans. It does not include inputs from dynamic changes to ice sheet flow
