Antarctica Is Changing Rapidly. The Consequences Could Be Dire

As seen from the place, Antarctica looks much easier than other continents – it is a great sheet of ice against the dark water surrounded by the southern Ocean. Although you go around and you will not get a simple cap of frozen water, but you will find an extraordinary complex interplay between the sea, the sea ice and the ice sheets and the shelves.

That relationship is in serious danger. A new Paper In the Journal Nature catalogs, in the past decade, a number of “sudden changes”, such as the loss of sea ice, are deriving in the water around it, strengthening each other, and threatening to cross the point of the continent – and threatening the coastal cities everywhere due to the rising of the sea.

“We are looking at the entire and amazing changes of development across Antarctica, but these are not happening separately,” climate scientist Nerily Abram, the top author of the paper says. (He conducted the research while he was at Australian National University but he was now the chief scientist of the Australian Antarctic Department.) “When we change a part of the system, it has an impact that makes changes to other parts of the system worse.

Scientists suddenly define the change as a slightly faster than expected at the environment. In Antarctica they can occur in scales and beyond centuries and beyond the weekends for a few days or weeks for a shelf of ice shelf. Unfortunately, these sudden changes can be self-performed and endless because people are warming the planet. Abram said, “This is the preferences we are making right now, and this decade and the next, for greenhouse gas emits that these promises will be placed for long -term changes,” Abram said.

One of the main drivers of the cascading crisis of Antarctica is the loss of ice in the floating sea formed in winter. In 2014, it reached a top of 20.11 million square kilometers or a 7.76 million square mile Antarctica (after the launch of the satellite observation in 1978). However, since then the sea ice coverage has not just exhausted, but almost incredibly a 55 -mile deal near the coast. During the winter, when the sea ice reaches its highest coverage, it has declined 4.4 times faster around Antarctica than the article in the last decade.

Put another way: Antarctica’s winter sea ice loss over the past decade is similar to what Artic has lost for the past 46 years. “People always think that the Antarctic Arctic is not changing compared to the Antarctica University of Ohio University, and I now think we are seeing the symptoms that it is no longer.” “We are looking just as fast – and in many cases, the change of Antarctic is faster than Arctic.”

Scientists need to collect more data to determine whether it is the beginning of the basic change in Antarctica, so far the signals are ominous. “We are starting to see the pictures of the pictures that we can be very well in this new condition of the dramatic loss of ice in the Antarctic sea,” a climate scientist who was not involved in the new research was Jatcheri M. Lab says.
