Shrinking polar ice caused one-fifth of sea level rise

Comprehensive analysis quantifies ice sheet loss in Greenland and Antarctica

Scientists now have one polar ice study to rule them all. An international team of researchers has compiled 20 years of data from 10 satellite missions to create the most comprehensive assessment to date of Greenland’s and Antarctica’s shrinking ice sheets.

DISAPPEARING ICE Greenland and Antarctica lost 4,260 billion metric tons of ice through melting (meltwater in Greenland shown) and calving icebergs, a new study finds.
