news agency Reuters accordingA series of rapid ice melts has doubled previous estimates of the loss of the world’s largest ice sheet in the past 25 years, a satellite analysis showed on Wednesday. According to the report, a first-of-its-kind study led by researchers from NASA’s Jet Propulsion Laboratory (JPL) has shown how rapidly climate change is weakening Antarctica’s giant ingots of floating ice and causing a tremendous rise in sea level. is increasing.
The study found that the mass of Antarctic ice caps has decreased by 12 trillion tonnes since 1997, more than double the previous estimate, due to the thinning of glaciers and the breaking of ice caps.
According to JPL scientist Chad Greene, the study’s lead author, the continent’s ice sheet loss due to the break-up of ingots in the last quarter-century is about 37,000 km (14,300 sq mi), roughly the size of Switzerland. area of.
“Antarctica is crumbling on its shores,” Green said in announcing the NASA findings, “and when ice caps shrink and weaken, the continent’s giant glaciers accelerate and the rate of global sea level rise increases.” increase in.”
The consequences can be very frightening. He said that Antarctica holds 88 percent of the sea level capacity of all the world’s ice.
Ice ingots, which are permanent floating sheets of frozen freshwater and are attached to land, take thousands of years to form, holding glaciers that would otherwise easily fall into the ocean, raising the ocean Will get up
