New research shows that Antarctic ice is disappearing five times faster than in the 1990s, threatening to raise sea levels and submerge many cities around the world.
Research on new satellite data is published in the journal Geophysical Research Letters comparing the height of ice sheets from 1992 to 2017 and shows that Antarctic ice is disappearing very quickly.
Guardian cites research showing that the Antarctic sea is hot, causing ice sheets to slide into the sea faster and faster. Ice is disappearing at a rate five times faster than in the 1990s.
The West Antarctic ice sheet is quite stable in 1992, but now about a quarter of the ice sheet is thinning. In the worst-hit areas, more than 100 meters of ice has melted.
If the West Antarctic ice sheet completely disappears, global sea level will rise by about 5 meters, submerging coastal cities around the world.

Scientists say the damage caused by melting ice is doubling every decade. Sea level has risen to the highest level compared to the forecast given only a few years ago.
Professor Andy Shepherd, of the University of Leeds in the UK, who chaired the study, said: "Since the 1990s, the ice has been thinning over the past 25 years. This has happened due to the impact of geography. substance, but now it is human. "
"During the 3,000 kilometers at West Antarctic, seawater comes into contact with overheated ice sheets, causing the underside of the ice sheet, which is in contact with the seabed, to melt. The tape then slid into the sea faster, "said Professor Shepherd.
Previous researchers have been aware that ice in the West Antarctic is disappearing, but the new study shows exactly where and how fast the ice melts. This helps make more accurate forecasts when sea level rises and can support preparedness.
Without rapid reductions in carbon emissions, melting ice and seawater will continue to rise for thousands of years, research warns.
"Before we can use satellite image analysis, most researchers think that polar ice sheets are not affected by climate change. Now we know that the reality is must be, "said Mr. Shepherd.
