Greenland and Antarctica shed 11,309 billion tonnes of ice over 44 years
A new scientific assessment has found that Greenland and Antarctica have collectively lost 11,309 billion tonnes of ice since 1979. This massive loss has contributed to a global sea level rise of 31.4 millimetres over the same period. The dominant driver was faster-flowing glaciers, which accounted for 84% of the total ice loss, while surface melting made up the remaining 16%. Researchers say the findings underscore the sustained and significant impact that warming oceans are having on polar ice sheets.
