In a confidential security review by Australia’s Defence Force, named “Climate Change, The Environment, Resources And Conflict”, the Australian army says climate change will pose “one of the biggest threats to security in the Pacific“. The confidential security review obtained by the Sydney Morning Herald newspaper also says that the natural resources under the melting Arctic ice may spark a global conflict.

“”Environmental stress, caused by both climate change and a range of other factors, will act as a threat multiplier in fragile states around the world, increasing the chances of state failure,” said the summary, published in the Herald on Wednesday.

“The Arctic is melting, potentially making the extraction of undersea energy deposits commercially viable. Conflict is a remote possibility if these disputes are not resolved peacefully,” the assessment said.”

According to the security review rising sea levels, caused by climate change, will “affect nations and islands with low-lying coastlines”, create climate refugees from the Pacific islands and result in more illegal fishing as food recourses will become rare.

Top German scientist Hans Joachim Schellnhuber warns that climate change is now happening much more quickly than anyone thought was possible.

In an interview with Saarbruecker Zeitung newspaper Schellnhuber, who heads the Potsdam Institute for Research on Global Warming Effects and acts as an adviser to German Chancellor Angela Merkel on climate-change issues, said that “the threats posed by climate change are worse than those imagined by most governments.”

“In nearly all areas, the developments are occurring more quickly than it has been assumed up until now. We are on our way to a destabilization of the world climate that has advanced much further than most people or their governments realize.”

Schellnhuber points out that the Arctic ice is melting faster than previously expected and says that “the entire climate pattern at the North Poll has been disrupted to the extent of causing irreversible change.”

CBS News reports that the Canadian Coast Guard is confirming “that in a major first, a commercial ship travelled through the Northwest Passage this fall to deliver supplies to communities in western Nunavut”.

“We did have a commercial cargo vessel that did the first scheduled run from Montreal, up through the eastern Arctic, through the Northwest Passage to deliver cargo to communities in the west,” Brian LeBlanc of the Canadian Coast Guard told CBC News.

“That was the first — that I’m aware of anyway — commercial cargo delivery from the east through the Northwest Passage.”

[…]Rayes, who was on the vessel during its trip through the Northwest Passage, said the company informed the coast guard, which put an icebreaker on standby.

“They were ready to be there for us if we called them, but I didn’t see one cube of ice,” he said.

“They were informed about our presence [and] they were ready to give us the support needed. However, since there was no ice whatsoever, the service was not needed, we didn’t call for it.”

Besides changing the climate and environment for people around the world the loss of Arctic sea ice is destroying the habitats for polar bears. Recently we reported about polar bears swimming to Iceland trying to find food and land. And now scientists are reporting that the starving polar bears are desperately resorting to killing and feeding on other polar bears as their natural habitats are rapidly being destroyed by man-made global warming.

“The Arctic sea ice melt is a disaster for the polar bears,” according to Kassie Siegel, staff attorney for the Center for Biological Diversity. “They are dependent on the Arctic sea ice for all of their essential behaviors, and as the ice melts and global warming transforms the Arctic, polar bears are starving, drowning, even resorting to cannibalism because they don’t have access to their usual food sources.”

Scientists have noticed increasing reports of starving Arctic polar bears attacking and feeding on one another in recent years. In one documented 2004 incident in northern Alaska, a male bear broke into a female’s den and killed her.

Unfortunately there seems to be no light in the tunnel for the polar bears. A new preliminary report from NASA shows that the sea ice at the Arctic continues to disappear and that the ice-levels this year has reached the second-lowest level on record.

A new preliminary report from NASA confirms our worries. The sea ice at the Arctic is disappearing.

NASA reports that the Arctic sea ice has reached a second all-time low “since the dawn of the satellite era”. Previous record low for September was in 2005. NASA says that this year’ loss of sea ice “further reinforces the strong negative trend in summer sea ice extent observed during the past 30 years”. In the past sea ice has covered about 60% of the Arctic. But this winter the sea ice covered less than 30%.

“In March, when the Arctic reached its annual maximum sea ice coverage during the winter, scientists from NASA and the data center reported that thick, older sea ice was continuing to decline. According to NASA-processed satellite microwave data, this perennial ice used to cover 50-60 percent of the Arctic, but this winter it covered less than 30 percent. Perennial sea ice is the long-lived layer of ice that remains even when the surrounding short-lived seasonal sea ice melts to its minimum extent during the summer.”

You might have heard from the climate change deniers that this year will be the coolest globally this century. And that is true.

Newly released data from the UK Met Office shows that during the first half of 2008 the global temperatures was more than 0.1 Celcius cooler than any other year after 2000. The reason for this is La Nina, an ocean-atmosphere phenomenon that has a cooling effect on the earth.

But this doesn’t mean the deniers are correct about anything else. Scientists still expects that 2008 will be the 10th warmest year since 1850. And the UK Met Office says that the global temperatures will continue to rise again when La Nina eases away.

Last week the ice at the North Pole melted at an “unprecedented rate.” And that has some scientists worrying that the Arctic could become ice-free during the summers as early as 2013, the Guardian reports.

The storms over the Alaska’s Beaufort Sea last week brought with them not just bad weather but also streams of hot air into the Arctic. Satellite images that were taken shortly after could show that the ice caps had started to “disintegrate dramatically.” And because of that the scientists believes that the melting could exceed last year’s record loss of ice.

This is a continuation on an earlier post called “It keeps getting warmer, no matter what some people say“.

Just like the global warming deniers say the Arctic ice is approximately the same as it was last year, as data from Nasa clearly shows. But, the Nasa data also shows that the old and thick Arctic ice is melting much faster than previous years.

Data shows that ice older than two years have decreased from 60% to 30% of the total ice mass in Arctic.

Seelye Martin, manager of the Cryospheric Sciences Program at Nasa headquarters in Washington DC, said that “although this March the area is slightly larger than last March, the area of [thick] perennial ice has reached an all time low.” And he concludes that “the volume of Arctic ice continues to decrease.”
