What is the total global glacial loss from 1993 to 2018?
The total cumulated global glacial losses over the 26 years from 1993 to 2018 were likely 5500 gigatons. This amounts to an average of 210 gigatons lost per year during that period.

Glaciers around the world retreated as the climate warmed substantially until about 1940 after the Little Ice Age ended between 1550 and 1850. Since 1980, climate change has led to glacier retreat becoming increasingly rapid and ubiquitous with some glaciers disappearing altogether.
The Thwaites Glacier alone holds enough ice to raise the world ocean a little over 2 feet or 65 centimeters. It currently contributes approximately 4 percent of global sea level rise while backstops neighboring glaciers that would raise sea levels an additional 8 feet if all their ice were lost.
By 1999, 89% of glaciers in the Italian Alps were retreating compared to only about a third in 1980. The Italian Glacier Commission found that 123 glaciers in Lombardy were retreating in 2005.
On the 13th of August 2005, the Ayles Ice Shelf broke free from the north coast of Ellesmere Island. This event followed the splitting of the Ward Hunt Ice Shelf in 2002 which has lost 90% of its area in the last century.
