Antarctica is melting more than six times faster than it did in the 1980s. That's according to a new study.

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

Since 2009, Antarctica has lost almost 278 billion tons of ice per year. That is what the new study found. In the 1980s, 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 is a University of California, Irvine, ice scientist. He was the lead author on the new study. It was was published recently in the Proceedings of the National Academy of Sciences. He 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. It 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 is a Pennsylvania State University scientist. He was not involved in Rignot's study. He called it "really good science."

    It's important because we need to see the rate that the heat is increasing at. If it will keep on constantly increasing at a consistent rate, it won't be good for future generations.

    Because it is a change that in a short time could alter the ecosystem, affect the habitat of some animals, and trigger natural disasters.At the same time, it tells us that global warming is progressing faster, since it mentions that in the last eighty years it has thawed 6 times faster.

    Due to climate change our land has gone through many evolutionary processes and one of them is Antarctica which in the text mentions that they traced the speed with which the southernmost continent has been melting since 1979, it is worth mentioning that the fusion in Antarctica Occidental and the Antarctic Peninsula represent approximately four-fifths of the loss of ice. This implies that we have to be more aware of the pollution on the planet.

    It´s amazing how we are destroying our future, our planet, our home, the aticle says that Since 2009, Antarctica has lost almost 278 billion tons of ice per year, the Antartic is suffering our bad habits to the nature, We think that the planet will bear forever but are in to change it, we are in time to save the planet, the climate change, is the time to be better, to be good people with the enviroment because is our home is our future.

    They made a study where it is appreciated that the ice of the antarctic is melting extremely fast, tons are being lost and this worries the humanity, because it increases the level of the sea and losses of species like polar bears, this article should arrive as message and do something about it not to pollution this is why global warming is.

    Probably, to the naked eye human beings can not realize the dimension of the situation in terms of the state of our planet earth, we live the day by day with a blindfold in the eyes ignoring the phenomenon that we have created and it is really worrying to see as there is evidence that supports the melting of ice by global warming.

    We are causing the pollution ourselves and it is worrisome, because the ice melts faster. We should not thow garbage anymore and we should take care of the wáter, before it is too and the ice melts completely.

    What I understand in the article and I think that affects me directly not only to me but to those around me is the speed with which are occurring the thawing of ice in the Poles, I hope we become aware and see the degree of danger we have all per We inhabit the planet

    did you know that Antarctica is melting 6 times faster than
    30 years ago due to climate change and air pollution its making the air warmer so that the ice melts i really enjoyed this article.

    Since 2009, Antarctica has lost almost 278 billion tons of ice per year. That is what the new study found. In the 1980s, it was losing 44 billion tons a year.They used aerial photographs and satellite measurements to measure. This is really bad it was losing 44 billion tons of ice per year now it is up to 278 per year.
