Um, That Global Warming Stuff? It’s Happening

What were you doing on Aug. 13, 2005? If you were a Canadian ice shelf, you were melting and breaking free. Yikes.

“What surprised us was how quickly it happened,” Copland said. “It’s pretty alarming.”

A giant ice shelf the size of 11,000 football fields has snapped free from Canada’s Arctic, scientists said. The mass of ice broke clear 16 months ago from the coast of Ellesmere Island, about 497 miles south of the North Pole, but no one was present to see it in Canada’s remote north. Scientists using satellite images later noticed that it became a newly formed ice island in just an hour and left a trail of icy boulders floating in its wake.

Warwick Vincent of Laval University, who studies Arctic conditions, traveled to the newly formed ice island and could not believe what he saw.

“This is a dramatic and disturbing event. It shows that we are loosing [sic] remarkable features of the Canadian North that have been in place for many thousands of years. We are crossing climate thresholds, and these may signal the onset of accelerated change ahead,” Vincent said Thursday…

Laurie Weir, who monitors ice conditions for the Canadian Ice Service, was poring over satellite images in 2005 when she noticed that the shelf had split and separated.

Weir notified Luke Copland, head of the new global ice lab at the University of Ottawa, who initiated an effort to find out what happened.

Using U.S. and Canadian satellite images, as well as data from seismic monitors, Copland discovered that the ice shelf collapsed in the early afternoon of Aug. 13, 2005.

“What surprised us was how quickly it happened,” Copland said. “It’s pretty alarming. Even 10 years ago scientists assumed that when global warming changes occur that it would happen gradually so that perhaps we expected these ice shelves just to melt away quite slowly, but the big surprise is that for one they are going, but secondly that when they do go, they just go suddenly, it’s all at once, in a span of an hour.”

Iraqi Suicides on Rise Due to Stress of Violence

Seeking relief: Medical experts in Iraq have noted a sharp rise in suicides in Iraq — most blamed on the psychological stress caused by unrelenting violence. The report was released today by IRIN, a UN humanitarian news and information service.

“We see more cases of suicide each month and all evidence shows that the main reason for the suicides has been the stress and pressure caused by the continuing violence,” said Dr. Muhammad Hamza, a specialist in suicide medical investigation at the Ministry of Health.

The Iraq Ministry of Health said that about 20 people have been committing suicide each month since January; 30 others attempted suicide but were saved.

Hamza said that he found that 70 percent of suicide victims chose to poison themselves using rat and cockroach poison. Others either shot or hanged themselves.

“Some of them leave letters to their parents and the most common excuse given for their act is that they can no longer bear the violence,” Hamza said.

“This week I had two cases of suicide. One person committed suicide because of the daily threats to his life which he had been receiving, and the other one because her husband had been killed and she became so desperate that she killed herself too,” Hamza added.

Based on statistics from the Baghdad mortuary and hospitals in five regions, the Ministry of Health said that about 20 people have been committing suicide each month since January. Thirty others attempted suicide but were saved.

“The numbers are high when compared to those during Saddam Hussein’s regime when we used to have one or two suicide cases a month,” said Ahmed Fatah, a member of the suicide investigation department at the Ministry of Health.
