Antarctic continent warms Ascertained

Antarctic continent at the South Pole grew warmer during the last half century as well as other parts of the world. A new study published in the journal Nature, the latest edition of the break which had expressed the opinion that the area even colder.

Studies conducted by U.S. scientists that carried out by combining weather records and satellite at the South Pole region that contains 90 percent of the world's ice. The results showed that freezing temperatures had risen by 0.5 degrees Celsius (0.8 Fahrenheit) since the 1950s.

The scientists concluded that the eastern region of the South Pole, which is larger and colder than the western part, grew warm 0.1 degrees Celsius per decade. While temperatures in the western part rose 0.17 degrees Celsius per decade, faster than the global average rise.

"What you hear all the time was Antarctica would be cool but not what happened," said study leader Eric Steig of the University of Washington. Previous studies did show that the temperature in most of the continent at the bottom of the earth remains the same or slightly cooler.

Over the years, the South Pole is the only place that looks odd as if immune from climate perubahah. Increased cold temperatures in some parts of Antarctica into a weapon for some researchers to give the argument that climate change is exaggerated.

However, recent research results mamatahkan assumption is much less done thoroughly in all parts of Antarctica. The scientists who still believe global warming affected Antarctica predicted cooling is only influenced locally by the cold wind blowing into the polar region.

Campaign "Global Warming", Prince Albert Explore Antarctica

Monaco's Prince Albert II left, start an expedition to Antarctica at the South Pole to arouse public awareness of global warming (global warming). The trip will complement the experience of first visiting the North Pole in 2006.

He will spend the time until January 22 and visit the 26th international base camp on the frozen continent. Place the first visit the destination is King George Island which is a research station with a number of countries. From there, the ship will stop at Patriot Hill base camp that became the U.S. researchers and Amundsmen-Scott who is a research center of France and Italy.

Furthermore, the mission of Vostok Station and proceed to the center of attention Novolazarevskaya Russia. From there, go to the Australian Davis Station, Princess Elisabeth Station is a base station researchers Belgium and Norwegian researchers.

"This is one of the most sensitive regions in the world. Everything that happens in Antarctica as Arctic daearah berpenagruh to all on this planet," he said. According to him, the mission of the expedition at once affirm support to Treaty Antaryiksa Monaco aimed at preventing commercial exploitation and military for narrow interests of each country.

Prince Albert II as the boys Puteri Rainier is known as a figure who care about the environment. Husband beautiful Hollywood actress Grace Kelly has been active in environmental activities alma even environmental foundation established in 2006.

One of them became one of the highest bidder for naming new species of fish found in Raja Ampat, West Papua through the Blue Ocean Auction two years ago. The funds provided are used to fund environmental conservation on the land and waters near the Bird's Head area of ​​Papua it.

Find Traces of Dirt Penguin

The scientists succeeded in finding 38 colonies of king penguins in Antarctica using satellite looking animal droppings.

Very hard to find a penguin if use the default image satellite because this animal is too small. However, penguins gather to eight months in the frozen sea, and those that accumulate dirt looks like a reddish brown marks on the frozen sea, so easily found.

The study colony is published by the magazine Global Ecology and Biogeography. "We're mapping one of our camp on the frozen sea, and we know there pengyin colony nearby," said Peter Fretwell, an expert on the geography of the British Antarctic Survey told the BBC.

"I use satellite images as a background map and see there are reddish brown spots on one possible location of the lake yan g king penguin colony." "This discovery happened because a few months before we make a mosaic of satellite images of Antarctica, so we can look back and find all existing colonies."

By comparing the satellite images that have a dot it with the location of the colony that was already known, the team successfully found 10 colonies of penguins that were previously unknown, and six colonies were already known but recently moved some distance away.

Six colonies of penguins that have been known before now completely disappeared. "We know that king penguins are very dependent on the frozen sea to breed - such as polar bears depend on sea ice to hunt. Although the frozen sea is quite stable, we are aware that in recent decades the frozen sea view will be reduced. We need know the location and number before we can conclude how much they are threatened by climate change, "said Fretwell.

Save Our Small Island, Keep Sea Level Rise

Ministry of Maritime Affairs and Fisheries (DKP) through the Marine and Fisheries Research Agency (BRKP) continue to disseminate the results of the World Ocean Conference (WOC) 2009 and Manado Ocean Declaration (MOD), among others in Palembang, South Sumatra.

Head of Regional Research Center for Marine and non-biological Resources Ministry of Marine Affairs and Fisheries, Dr Budi Sulistyo said it continues to strengthen the mitigation system to avoid loss of small islands and the impact on climate change in the form of rising sea levels.

Strengthen mitigation system to maintain marine ecosystems, becoming one of the efforts to maintain the existence of small islands and reduce the impact of global climate change that.

"Losing a number of small islands that occurred recently is the phenomenon of climate change impacts are increasingly perceived the world community, among others, due to melting icebergs at the poles," he said.

Keeping in coastal marine ecosystems is an effort to mitigate the loss of small islands and rising sea levels.

"Indonesia is very vulnerable to climate change impacts, such as the degradation of coastal and island," he said.

Exploitation of natural resources in coastal sea by irresponsible parties, has created pollution and fatal damage.

"As a result, marine disaster strikes, whether it be flood or rob the impact further impoverishing the people who live in the coastal ocean," he said.

The government should issue a variety of coastal management policies and small islands based mitigation, so as to anticipate the impact of climate change.

"Improving the environment by reforestation, preserving the mangrove forests and coral reefs, it is important to anticipate the impact of climate change," said Budi.

By implementing various strategies and programs to protect marine ecosystems are expected to anticipate the disaster that could happen.

"Efforts to rehabilitate and restore the carrying capacity of damaged marine resources with the active role of government and society is expected," he said.

World Ice Melt Faster

The mountains melt ice world in a very fast pace and some of them can be lost in coming decades, according to disclosed Programme United Nations  Environment  (UNEP),

The scientists who examined some 30 layers of ice conditions around the world found that ice melt reaches its peak in 2006.

Therefore, UNEP warned that further ice loss could have serious repercussions, especially in India, where rivers originating in the Himalayas ice.

West coast of North America that get some water from glaciers in mountain ranges like the Rocky and Sierra Nevada will also be affected.

UNEP executive director Achim Steiner urged governments to agree on measures to reduce greenhouse gas emissions in an international meeting next year in the Danish capital, Copenhagen.

Average ice cover is reduced 1.5-meter world in 2006. Ever recorded in a melt layer of ice Breidalblikkbrea, Norway, which yield 3 meters in 2006, while Echaurren Norte glacier in Chile is the only one who grew thicker.

"What we get is likely a trend that is not known when to stop," said Wilfried Haeberli, director of the World Glacier Monitoring Service.

It says Haeberli, ice melted about 0.3 meters per year between 1980 and 1999. But since 2000, the melt was increased by about 50cm.

Floating Iceberg Hijrah to New Zealand

Hundreds of floating icebergs from the Antarctic are now moving to New Zealand. This rare event forced the local government issued a warning to the crew of a passing ship in the area.

Australian Antarctic Division Glaciology Agency said the point of ice visible from satellite photographs have been passing the island of Auckland and is now heading towards the South Island, which is about 450 kilometers northeast.

Neal Young Scientists reveal, more than 100 of the iceberg, - the estimated size of about 200 meters of it - can be seen only in one cluster. This marks at the site there are hundreds of icebergs.

He said that the floating object is the remnant of the iceberg that broke away from Antarctica due to global warming.

"What is there now, come from a larger iceberg, which may berukuransekitar 30 kilometers square when he left the Antarctic," he explained.

New Zealand coastal navigation warnings are often issued for southern waters where chunks of ice in sight. "This is really a warning to shipping in the area that many dilabuhi chunk of the iceberg," said Maritime New Zealand spokesman Ross Henderson.

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.
