effect of global warming

chunk of ice spreading across seven square miles has broken off a Canadian ice shelf in the Arctic, scientists said Tuesday.Derek Mueller, a research at Trent University, was careful not to blame global warming, but said it the event was consistent with the theory that the current Arctic climate isn't rebuilding ice sheets."We're in a different climate now," he said. "It's not conducive to regrowing them. It's a one-way process."Mueller said the sheet broke away last week from the Ward Hunt Ice Shelf off the north coast of Ellesmere Island in Canada's far north. He said a crack in the shelf was first spotted in 2002 and a survey this spring found a network of fissures.The sheet is the biggest piece shed by one of Canada's six ice shelves since the Ayles shelf broke loose in 2005 from the coast of Ellesmere, about 500 miles from the North Pole.Formed by accumulating snow and freezing meltwater, ice shelves are large platforms of thick, ancient sea ice that float on the ocean's surface. Ellesmere Island was once entirely ringed by a single enormous ice shelf that broke up in the early 1900s.At 170 square miles and 130-feet thick, the Ward Hunt shelf is the largest of those remnants. Mueller said it has been steadily declining since the 1930s.Gary Stern, co-leader of an international research program on sea ice, said it's the same story all around the Arctic.Speaking from the Coast Guard icebreaker Amundsen in Canada's north, Stern said He hadn't seen any ice in weeks. Plans to set up an ice camp last February had to be abandoned when usually dependable ice didn't form for the second year in a row, he said."Nobody on the ship is surprised anymore," Stern said. "We've been trying to get the word out for the longest time now that things are happening fast and they're going to continue to happen fast."

3. EconomicsThis section examines the types of economic activity found in South Asia at the start of the twenty-first century. The lesson also explores the region’s rich economic history, with focus on the post-independence period, and the six prominent drivers of economic development.
4. Population, Health, Environment, and ConflictThis segment looks at the issues of population, health, the environment, and conflict and their significant social and human consequences in South Asia. Reducing population growth, improving health and health care, reversing environmental decline, and resolving conflict are vital issues for the region.
5. South Asian Social and Cultural IssuesHome to one of the world’s oldest civilizations, the region has a history of social fragmentation and cultural diversity. This lesson explores the roots of South Asian society and culture, focusing on four important areas: religion; family life and the role of woman; the arts, architecture, and literature; and recreation and leisure.
6. South Asia in World AffairsThe instructional guide and videotape conclude with an overview of relations between the countries of South Asia and the rest of the world. The September 11, 2001 terrorist attacks in the United States demonstrated how sizeable a role South Asia plays in world affairs

globalisation

It was the anti-globalisation movement that really put globalisation on the map. As a word it has existed since the 1960s, but the protests against this allegedly new process, which its opponents condemn as a way of ordering people's lives, brought globalisation out of the financial and academic worlds and into everyday current affairs jargon.
But that scarcely brings us nearer to what globalisation means. The phenomenon could be a great deal of different things, or perhaps multiple manifestations of one prevailing trend. It has become a buzzword that some will use to describe everything that is happening in the world today.
The dictionary definition is a great deal drier. Globalisation (n) is the "process enabling financial and investment markets to operate internationally, largely as a result of deregulation and improved communications" (Collins) or - from the US - to "make worldwide in scope or application" (Webster). The financial markets, however, are where the story begins.
In the late 1980s and early 1990s, the business model termed the "globalised" financial market came to be seen as an entity that could have more than just an economic impact on the parts of the world it touched.
Globalisation came to be seen as more than simply a way of doing business, or running financial markets - it became a process. From then on the word took on a life of its own. Centuries earlier, in a similar manner, the techniques of industrial manufacturing led to the changes associated with the process of industrialisation, as former country dwellers migrated to the cramped but booming industrial cities to tend the new machines.
So how does the globalised market work? It is modern communications that make it possible; for the British service sector to deal with its customers through a call centre in India, or for a sportswear manufacturer to design its products in Europe, make them in south-east Asia and sell them in north America.
But this is where the anti-globalisation side gets stuck in. If these practices replace domestic economic life with an economy that is heavily influenced or controlled from overseas, then the creation of a globalised economic model and the process of globalisation can also be seen as a surrender of power to the corporations, or a means of keeping poorer nations in their place.
