Ice Threatens Sailing

The results showed a satellite photograph, a large chunk of ice had just passed the area of ​​the island toward the main island of Auckland and South Island, about 450 kilometers northeast. "The warning applies to all ships in the region to be aware of the existence of the iceberg," said New Zealand's marine spokesman, Ross Henderson, AFP reported

The presence of large ice blocks in the group that submitted the glacier expert from the Australian Antarctic Division. They continue to monitor the movement of the ice chunks.

According to them, ice blocks are part of a giant blocks seen in last October around Macquarie Island, Australia. At that time, two large blocks of the first two kilometers wide and the second at the Olympic Stadium "Bird Nest" Beijing-tracked there.

Meanwhile, observed heading to New Zealand last Monday was fragmented in various sizes. Some of them have a width of 200 meters.

"All come from one big chunk, which may be the extent of 30 square kilometers in the Antarctic," said one expert glaciers, Neal Young. Increasing global temperatures and sea level due to global warming has been blamed as the cause.

After three years

According to Neal Young, chunks of ice in large numbers last seen floating near New Zealand in 2006. At that time, only 25 kilometers away from the coastline-the first event after 1931.

For the purpose of publication, in 2006, a helicopter transported sheep shorn on iceberg that is floating. New Zealand is known as a center for the wool industry.

"What it looks today has the same movement path towards New Zealand. Did towards South Island, it is difficult to say, "he said.

However, he believes will more often see the same thing if global temperatures continue to rise. Some experts are not sure of this.

The reduced extent of Antarctic ice in Antarctica has been identified in recent years. However, reduced ice cover in the east Antarctic region in large numbers, during the last three years, considered the experts as a "surprise".

Unlike ice sheet in western Antarctica, which is known vulnerable and unstable, a layer of ice in eastern Antarctica was known to be stable. However, some experts do not believe the phenomenon is closely related to climate change.

Prediction loss

In the midst of pros and cons the polar ice melt as a result of global warming, WWF launched a study in Switzerland, last Monday. Major flooding expected to hit the major port cities in the world and causing damage to 28 trillion U.S. dollars in 2050.

Sea-level rise will reach half a meter if global temperatures rise 0.5 to 2 degrees Celsius during the current period until 2050. At the time that the loss of trillions of dollars generated from 136 large port city in the world.
