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

Scientists used many tools. They used aerial photographs. They used satellite measurements. They used computer models. They tracked how fast the southern-most continent has been melting. They have tracked it 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.

Antarctica has lost almost 278 billion tons of ice per year. This has happened since 2009. That is what the new study found. Before it was losing 44 billion tons a year. This was in the 1980s. 

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

Eric Rignot works at University of California, Irvine. He is an ice scientist. He was the lead author on the new study. It was was published recently. It was published 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. Before, it was considered stable.

Last year's study took several teams' work into consideration. It found little to no loss in East Antarctica recently. It showed 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 sea level rise over the next century or so," Rignot said.

Richard Alley works at Pennsylvania State University. He is a scientist. He was not involved in Rignot's study. He called it "really good science."

    So then they can study of what is melting the ice and what makes it melt quicker. the ice could be more different than regular ice.

    Antarctica is melting ice 15% more than last year that is really good.

    To help us learn more about the climate and find out the problems that we will have.

    Its importaint to show how much its melting per year.

    I think its important because its important to preserve it

    It's important because it can show how the world is being affected by climate change

    I think it is important to study the melting of the ice in Antarctica to know when seasons are changing.

    I think it is important to study the ice melting in Antarctica because you need to see how much ice is disappearing in Antarctica. The ice melting is almost always caused by human-caused climate change. If we could figure out what we are doing, then we could prevent the ice form melting.

    It is important to study the melting ice in Antarctica because it effects other places around the World. One of these big problems are the rising oceans which are pushing back the coasts.

    I think it is important to study the ice because we would know how fast the ice is melting. When we see how fast the ice is melting we will know when only the land below the ice will be left.
