Find the answer to Antarctic paradox

Weather experts, after trying to explain the phenomenon of expanding Antarctic ice area, found the cause - warming the Earth.

Experts say the reason is because water ice melting in the Antarctic ice sheet will freeze on the surface.

The area of ​​ice in Antarctica reached a record in September 2012.

The sea ice around the Antarctic area is expanding, while the icefall in the Arctic reaches a record.

A group of scientists from the Royal Dutch Climate Institute said that fresh water due to melting Antarctic ice sheets has a lighter density than the density of seawater. So they gather on the sea surface in the summer months. In autumn and winter, this amount of water will freeze back in a large area. The team predicts that this phenomenon will continue.

Earth's 2 poles have very different weather patterns. Surrounded by North America, Greenland and two Eurasian continents, Arctic ice sheets float on the surface of the ocean, not on land. It has lost a large portion of old, thick ice sheets over the past 30 years, which makes it more susceptible to global warming.

There are scientists who think that wind is the "culprit" that makes the area
The tape increased, but this hypothesis seemed hard to stand.

Meanwhile, Antarctica is a continent surrounded by open waters. This may be the reason the Antarctic ice sheets are expanded in winter, and melted much in the summer.

However, the Dutch scientists report also said that although the surface area of ​​the ice is extended every winter, the total area of ​​ice around the Antarctic region continues to decrease because of the underwater ice. is melting.
