Between 1992 and 2020, the polar ice sheets lost 7,560 billion tons of ice.

Ice loss from Greenland and Antarctica has quintupled since the 1990s and now accounts for a quarter of sea level rise, according to a report published this Thursday by the European Space Agency (ESA).

Scientists have used data from satellites such as ESA's CryoSat and the European Union's Copernicus Sentinel-1 to measure changes in ice volume and flow, as well as satellites that provide gravity information to determine how much ice is being lost. .

The latest IMBIE assessment, which was published this Thursday, establishes that between 1992 and 2020, the polar ice sheets lost 7,560 billion tons of ice, equivalent to an ice cube 20 km on a side.
