غرينلاند وأنتاركتيكا تفقدان 11.3 تريليون طن جليد
(opens the publisher’s site)A study published Wednesday found the Greenland and Antarctic ice sheets lost 11.3 trillion metric tons of ice since the 1970s, raising global sea levels by about 3.1 centimeters.
- The study, published in Scientific Data, drew on 45 independent surveys and data from 27 satellite systems operated by the European Space Agency and NASA.
- Researchers said about five-sixths of the loss stems from warmer ocean waters eroding the sheet bases and accelerating glacier flow into the sea.
- Lead researcher Inès Otosaka said each additional centimeter of sea rise could expose two to three million more people to annual coastal flooding.
- Co-researcher Eric Rignot said the ice sheets are "melting fast," warning that rising seas would heighten coastal exposure.
