The two cracks grow in west Antarctica, the Pine Island Glacier, as well as, they are an ominous warning that a huge ice-loss was on the road.
This is not the first time a large ice losses in the past few years. Almost a year ago, on Oct. 29, 2018, an iceberg measuring about 116 square miles (300 square kilometers) calved from the glacier, which is less than a month after a large crack appeared.
Shortly after the birth of the iceberg, B46, and a lot that are good for the 87 square kilometres (226 square miles) in October, 2018, with ice-cream, the loss, the two new fissures appeared, and said, Mark Drinkwater, head of the Earth, and the Mission Sciences Division of the European Space Agency (ESA).
These cracks have been spotted, in the beginning of 2019 at the latest, by the ESA’s Copernicus Sentinel-1 and Sentinel-2 satellites.
Recent satellite observations show that the new cracks are growing, the ESA reported in a statement. Every one of the cracks, it measures approximately 12 miles (20 km) in length. With their expansion, suggesting that the ice shelf is faced with an immediate and significant ice loss, according to the ESA.

“Sentinel-1 in winter to monitor their progressive expansion, the signs that there is a new iceberg in terms of similar relations that will soon be off,” Water said in a statement. To put that into perspective, an iceberg that large, it would stretch to more than twice the area of Paris, france.
Satellite Network operations for polar observations. But the Sentinel-1 has been linked to satellite imagery is particularly useful for checking the status of the ice of the Pine Island Glacier, which is one of these satellites is an imaging system called synthetic aperture radar (SAR), which images the whole year through, in winter, in the dark winter months, and in any type of weather, in accordance with the ESA.
When an ice tongue of the Pine Island Glacier is to the left of the West Antarctic ice sheet in the Amundsen Sea. It is one of the fastest-receding glaciers in the Antarctic, and the birth of the incidents have increased in the past few years, NASA reported. With global warming, the ocean currents are melting the glaciers from below, and the washing of the ice is way faster than a glacier, the ESA said.
Prior to the end of 2018 calving of the glacier and suffered two massive ice losses in 2015 and 2017, raising concerns among glaciologists about the future of the region’s stability.
“In terms of the frequency, it is a lot more happening than in the past,” Seongsu Jeong, a postdoctoral researcher at the Byrd Polar and Climate Research Center at The Ohio State University, told Science in 2017.
