The new data confirmed that most of the melting happened on ice - covered Greenland and Antarctica, where enough ice melted to raise sea levels by 1.06 millimeters (0.042 inches) per year between January 2003 and December 2010, the study period.

Glaciologists analyzed ice flow to the ocean from 1991 to 2015 in the Queen Elizabeth Islands, and found that surface melt grew by a whopping 900 percent, or 10 times, in the 10 years between 2005 and 2015, increasing to 30 gigatons per year by the end of that time.

Simultaneously the best studied Greenland glacier, the Jakobshavn, began retreating from its Little Ice Age maximum with it fastest observed retreat of 500 meters per year between 1929 and 1942.

For comparison, between 2003 and 2010, sea levels rose about 0.05 inches (1.5 mm) per year because of melting ice, and an additional 0.06 inches (1.7 mm) because of thermal expansion of the warming waters.

Richard Telford suggests that equilibrium between local ice cover and local temperature occurs within several decades because melt rates of 0.5 m per year have been observed.

Berthier and his co-authors recently reported that Cook Ice Cap shrank at 2.4 km2 / yr, half a percent per year, between 1963 and 2001.
