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."

    I think its important to study the ice melting in Antarctica so we can learn how to stop it. Imagine all the animals that would lose their homes or maybe even go extinct!

    It isn't good thhat Antartica is melting 6 times faster than it was in the 1980's because now the water level is going to rise drastically.

    It is important because the ice is melting which means the animals could die. The animals who live there need the ice in some way to survive. If all the ice melts the fish would be harder to catch and the animals wont have food.

    so we can prevent the water from rising and major islands getting over flowed by water.

    Antarctic is currently melting six-times faster than in the 1980s, making this an indicator of human-caused change. This brings in civic engagement, because scientists are the public are trying to do something about it. An example from the article is Eric Rignot, who is an ice scientist and the leader on a new ice study. In fact, he published the study already. Basically, East Antarctica has been losing 56 billion tons of ice per year; however, they also found out ? of the melting has been happening in West Antarctica and at the Antarctic Peninsula. Due to all the ice melting, sea level has also risen. Ultimately, global warming is a real problem that the public and professionals are trying to solve.

    We really need to try to stop global warming. Donald trump may not think its real but that doesn't mean it isn't.

    Without ice Antarctica not only will it not be the same. Its contenders, polar bears, penguins,etc.. Will die off. Leaving Antarctica in collapse.

    I think it's important to study the ice melting in Antarctica because then you would know when all the ice is gone.

    People need to stop pullution and recycly

    wow! That is terrible !!! I think people should help stop this.
    i for one think people should stand with the scientist. help the the water not flood the world !
