Researchers in the United States and several other countries published a study on Monday that found two Change rapidly Glaciers in Antarctica, the Pine Island Glacier, and the Thaiweats Glacier have developed “crevices and open fractures,” which “indicate their structural weakness.”
“These damaged areas are closely associated with cracked areas and open fractures and are the first signs that the area around the edges of both ice shelves has become significantly weaker over the past decade,” the researchers wrote in the abstract. .
Decades of changes in atmospheric and ocean conditions have caused sea levels to rise due to melting glaciers. According to the study, the Pine Island Glacier and the Thaiwits Glacier are responsible for about 5% of global sea level rise.
“Both glaciers reflect different changes in recent decades as environmental and ocean conditions change, causing the ocean-driven advances to melt their floating ice caps,” the researchers said.
Global sea level is rising at a rate of about 1.4 inches per year Accordingly Science Times.
If both glaciers break, many of the neighboring areas will also collapse, leading to a massive collapse. Told.
Damage development for the Pine Island Glacier began around 1999, and damage development for the Thaiwits Glacier began around 2000 but “moved on” around 2016, satellite imagery shows.
Glacier ”Shear zoneAreas of serious deterioration have increased by about 30% since 1992, and the fastest growth between 2000 and 2010.
The researchers concluded that it was impossible for glaciers to collapse completely in the near future because surface melting is rare, but damage in the shear zones would “make them vulnerable to massive damage and ground line return.” Is. ”
