Ice shelf in Canadian Arctic region breaks off

With our current sea water levels, we maintain a uneasy balance with the seas and oceans in coastal areas. Housing, habitation, and other forms of human existence are right till the doorstep of the water, and there are millions of people living on islands that are only a few meters about the surface of the seas. When we get a storm (call it a hurricane / typhoon / cyclone), the wave front pushed up by the storm typically expands inwards towards land and causes damage; the stronger the storm, the more the damage.
We are also getting more and more into the region where we can start seeing the effects of global warming, and as yet, the engines of civilization are still pumping more chemicals into the air that increase the speed of global warming. Worldwide, countries are not able to agree on what to about global warming, since they fear that any such action will cause an economic damage (never mind that 20-30 years later, we will see much more damage to humanity). As per projections, the massive ice shelfs that exist in the Arctic, the Antarctic, and Greenland contains enough water to raise sea water levels by many meters, and thus unprecedented damage. Scientists are slowly observing that they were not paranoid enough, that there are changes happening to the ice shelfs much ahead of projection:

A 19-square-mile (50 kilometers) ice shelf attached to an island in Canada’s northern arctic for thousands of years has broken from land, another sign of the effect of global warming, scientists said. Nearly the size of Manhattan, the 4,500-year-old Markham Ice Shelf separated from Ellesmere Island in early August and is now floating in the Arctic Ocean, said Luke Copeland, director of the Laboratory for Cryospheric Research at the University of Ottawa.
In January, the National Aeronautics and Space Administration said net loss of ice mass in Antarctica increased to 196 billion metric tons in 2006 from 112 metric tons a decade earlier. To have a chance of containing the average worldwide increase in temperature to 2 degrees Celsius (3.6 degrees Fahrenheit) would require cutting global greenhouse gas emissions by 50 to 85 percent by 2050, according to the UN panel. Ice shelves, which attach to land and float on the ocean’s surface, form through the accumulation of snow and freezing water.

Movement towards preserving the continued economic growth and future of humanity is conditioned upon being able to forestall events that can cause harm to humanity, and this dithering over responsibility and fear of current economic harm if trying to implement caps on emissions is slowly destroying our future.
