NASA claims that Antarctica is losing ice at a rate that nature cannot replenish


An investigation by NASA’s Jet Propulsion Laboratory (JPL) revealed that Antarctica’s coastal glaciers are shedding icebergs at a faster rate than nature can replenish the crumbling ice.

This diagnosis by scientists suggests that Previous estimates of losses from the world’s largest ice sheet over the past 25 years are doublingsatellite analysis showed on Wednesday, August 10.

The study published in the academic journal Nature and cited on CNN raises new concerns about how quickly climate change is weakening Antarctica’s floating ice shelves and accelerating global sea level rise.

The conclusions of the study

The main conclusion of the researchers is that the net loss of Antarctic ice due to the calving of pieces of coastal glaciers into the ocean it’s almost as large as the net amount of ice that scientists already knew was being lost due to thinning caused by melting ice shelves from below by warming seas.

Chad Greene, lead author of the study, explained: “Antarctica is crumbling at its edges. And when the ice shelves shrink and weaken, the continent’s huge glaciers tend to accelerate and increase the rate of global sea level rise”.

Together, thinning and calving have reduced the mass of Antarctica’s ice shelves by 12 billion tons since 1997, twice the previous estimate.

The net loss of the continent’s ice sheet from calving alone in the last quarter century covers almost 37,000 square kilometers, an area almost the size of Switzerland, according to JPL scientist

Antarctica hosts 88 percent of the sea-level rise potential of all the world’s ice, he said, so the consequences could be huge. Ice shelves take thousands of years to form and act as buttresses holding back glaciers that would otherwise easily slide into the ocean, causing the sea to rise.
