Satellite data helps pinpoint Antarctic ice loss

Study says 92 billion tons of ice melting each year

The ice sheets of West Antarctica are losing about 240 billion tons of ice each year, and the rate of loss has doubled in the past 10 years. @bberwyn photo.

FRISCO — Sparse data make it tough to track continental-scale climatic changes across the vast reaches of Antarctica. But a new study that analyzed gravitational readings from satellites is helping scientists understand what’s happening to the region’s massive ice fields, and in a new study, they say that, overall, the southern continent’s ice cap is melting ever faster.

The study covers a 10-year span, from 2003 to 2014, when an average of 92 billion tons of ice melted away into the sea each year, with obvious implications for sea level rise. Reporting in the  journal Earth and Planetary Science Letters, the Princeton researchers said that, if all that ice were piled on Manhattan it would be more than a mile high, five times the height of the Empire State Building.
