A new scientific “Review Article: Earth’s ice imbalance” by Slater et al. found that Earth lost a net 28 trillion tons of ice from 1994 to 2017. Breakdown in trillions of tons, largest to smallest, is: Arctic sea-ice 7.6, Antarctic ice shelves 6.5, Mountain glaciers 6.2, Greenland ice sheet 3.8, Antarctic ice sheet 2.5, and Antarctic sea-ice 0.9. 60% is from the Northern Hemisphere, 40% from Southern Hemisphere. Rate of ice loss has increased 57% since the 1990’s (from 0.8 to 1.2 trillion tons/year). 68% is from atmospheric melting, 32% is from oceanic melting. Overall, the ice melt has taken up 3.2% of the global energy budget
