Antarctic ice loss increases six times since 1979, a new study finds itself



Global warming The ice of the Antarctic is melting faster than ever, six times more than six years ago, to increase sea levels, scientists have warned.

Already, the Antarctic melting world sea level increased by 1.4 cm between 1979 and 2017 according to the Academy of Sciences Academy (PNAS) Processes report.

And the pace of meltdown is expected to rise to sea level in the coming years, according to Eric Rignot, a scientist at Earth Sciences Systems at the University of California, Irvin.

"As long as the ice sheets in Antarctica continue to melt, we expect a sea level of up to a million meters in Antarctica in the coming centuries," said Rignot.

The length of 1,100 meters (six meters) by the year 2100, as scientists predict in a bad state, would cause flooding in several coastal cities with millions of people around the world. Previous research has shown.

For current research, researchers have conducted the longest evaluation of the Northern Antarctic in 18 geographical regions.

Since researchers found it since 1979 to 1990, Antarctica broadcasts more than 40 million tons of ice.

Between 2009 and 2017, the ice losses were six times more than 252 million tonnes per year.

Even more disturbing, the researchers found that a temporary "steady and changing variation" had been placed in eastern Antarctica, although many ice became apparent, the study said.

"The Wilkes Land Land of the East Antarctic, in general, has always been an important participant in the loss of masses, even though it has reached the 1980s, as our research has shown," said Rignot.

"The Earth is probably a more sensitive climate, and it's important to know that it's more ice than the Antarctic West and the Antarctic Peninsula."

Ice loss

The total amount of ice in Antarctica, if everything melts, would be enough to lift the sea level 187 meters (57 meters).

Most of the Antarctic ice are located in the east, with enough ice to reach 170 meters of water from the sea, namely 17 foot of the West Antarctic ice.

Eastern Antarctic ice is the largest in the world, with less than half of the Earth's freshwater.

Up to now, most research has shown that most melting occurs in the West.

The scientific research published in the Nature magazine in June last year was found to be tripled from the Antarctic ice melting since 1992, but did not show significant melting in the east.

However, a study published in September of the Nature magazine in September 2018 analyzed ocean ocean sediment layers, the Wilkes Subglacial Basin, in southern Australia in Eastern Antarctica, when it melted over 125,000 years ago.

This research found that the massive basin was melting again, maintaining a sustained temperature, two-degree Celsius caps, in Paris's climate forecast, to prevent global warming.

The latest research shows "more attention" worthy of melting in East Antarctica, according to the PNAS report.

Ocean warming will accelerate future losses due to ice loss and experts say that sea levels continue to depend on climate change.

Recent research has shown that oceans are hotter than previously thought, setting new hot records in recent years.
