According to a recent study, Antarctica is melting more than six times faster than it did in the 1980s. 

Scientists used many tools during the study - aerial photographs, satellite measurements and computer models - tracking how fast the southern-most continent has been melting since 1979 in 176 individual basins. They found the ice loss to be accelerating dramatically - a key indicator of human-caused climate change.

The recent study found that, since 2009, Antarctica has lost almost 278 billion tons of ice per year, compared to the 1980s, when it was losing 44 billion tons a year.

The recent melting rate is 15 percent higher than what a study found last year.

Eric Rignot, a University of California, Irvine, ice scientist and lead author on the new study that was published recently in the Proceedings of the National Academy of Sciences, said the big difference is that his satellite-based study found East Antarctica is losing 56 billion tons of ice a year. Previously, it was considered stable.

Last year's study took several teams' work into consideration and found little to no loss in East Antarctica recently and gains in the past.

Melting in West Antarctica and the Antarctica Peninsula account for about four-fifths of the ice loss. East Antarctica's melting "increases the risk of multiple meter (more than 10 feet) sea level rise over the next century or so," Rignot said.

Richard Alley, a Pennsylvania State University scientist not involved in Rignot's study, called it "really good science."

    Why do I think it is important to study the ice melting in Antarctica is because if the ice melts it will cause the water level to rise and it will not be good if the water level rises. It could also harm the animals living on the land if the ices melts away. The recent melting rate is 15 percent higher than what a study found last year.

    It is important because of its profound effect on the Earth's climate and ocean systems. Locked in its four kilometre-thick ice sheet is a unique record of what our planet's climate was like over the past one million years.

    The melting of Antarctica is increasing at extreme rates causing Scientology’s do more test. Thankfully they are working together and comparing their ways of measurement to find the answers that they are able to agree upon. It is quite unfortunate that climate changes was first called global warming.

    Antarctica is melting is increasing at extreme rates casing scientist to do more test and observations. Also they are working together and comparing the way they will find the answers.

    The study found that that East Antarctica is loosing 58 billion tons of ice per year. Antarctica is melting at a faster rate than it was last year, about 15% faster. The team from University of California Berkeley has monitored the rate of melting since the 70's. They are concerned with how fast the glacier is melting, as a result of melting sea levels will rise

    Cold meltwater running off Antarctica's ice sheets and into the ocean could dampen the pace of global temperature rise, a new study suggests. The research, published in Nature, finds that the rate of ice-sheet melt in a high-emissions scenario could see the oceans cooled by the influx of frigid water.

    Because animals live in Antarctica and they can become extinct if all the ice melts in Antarctica

    It is important To Study the ice in Antarctica Because nobody studies the ice

    I thinks import to study because of its profound effect on the Earth's climate and ocean systems. I also think its important because to study antarctic because the scientist says that the meltwater could have wider impacts on the Earth's climate, increasing the formation of Antarctic sea ice, reducing rainfall in the southern hemisphere and increasing rainfall in the northern hemisphere.

    It important to study the melting in Antarctica because Antarctica is losing a lot of ice so scientists are working and comparing their ways to help Antarctica. Us humans toady need to help out our environment because we are losing ice to where some ice animals live. About 270 billion that Antarctica has lose ice for the past year and i hope one day we can help our environment
