Satellite Data Shows Major Ice Losses for Greenland and Antarctica
A study using 42 satellite estimates found glaciers, not surface melt, caused 84% of the loss and lifted sea level by about 1 inch.
- A new study published in Scientific Data calculated that Greenland and Antarctica lost 11.3 trillion tons of ice between 1979 and 2023, making them major contributors to rising global sea levels.
- Researchers found that 84% of combined ice loss came from glaciers speeding up as they flowed into the ocean, while 16% came from surface melt, revealing the primary mechanism driving the decline.
- Global average sea levels rose about 3 centimeters due to this loss, said Inés Otosaka of Northumbria University, who noted the volume could fill a cube 23 kilometers high.
- The two ice sheets are now responsible for roughly one-quarter of global average sea-level rise, threatening coastal communities through worsening flooding and infrastructure damage worldwide.
- Otosaka's team now plans to estimate ice loss region by region, aiming to improve sea-level projections and help vulnerable communities prepare more effectively for future impacts.

Satellite data shows major ice losses for Greenland and Antarctica
Researchers said the total sea-level rise from ice losses may not sound like a huge number, but it puts 6 to 9 million people at risk of flooding and erosion.
Earth Lost More Than 12 Trillion Tons of Ice in 47 Years, Satellites Reveal
Greenland and Antarctica lost about 11.3 trillion metric tonnes of ice between 1979 and 2023, contributing roughly 3.14 centimetres to global sea-level rise, according to a new study published in Scientific Data. The assessment, led by the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), combines 42 independent estimates from 27 satellite missions to produce one […]
Satellites show Earth lost more than 12 trillion tons of ice from Greenland, Antarctica in 47 years
About 12.5 trillion tons (11.3 trillion metric tons) of ice from glaciers in Greenland and Antarctica have melted since 1979, which is enough frozen water to stack ice 5 feet (1.5 meters) deep across the continental United States, according to a major scientific report.
The longest satellite record ever compiled shows that the ice sheets in Greenland and Antarctica have been around eleven since the 1970s.
