Talking issuesFor inhabitants of the Artic, global warming is more than just a scientific debate about a distant threat. It is an everyday reality. The ice is getting thinner, and animals that form an integral part of the local diet are moving farther north.The ground, once permanently frozen, is beginning to melt, causing major damage to houses and roads. Jhon Chugiak, an enviromental campaigner from Banks Island in the far north of Canada, wantsthe world to wake up to the problem. "Our traditional lifestyle has already changed due to global warming," he says, "and it´s going to change a lot more. My people aren´t going to be able to hunt and fish much longer, and our houses are going to fall down." Soon people will start leaving for the big cities, and our town may even die. Our town may even die. Our whole way of life might be best. Global warming occurs when greenhouse gases, such as water vapor and carbon dioxide,accumulate in the atmosphere. These gases prevent heat from escaping into space and, as a result, the planet warms up. If levels of greehouse gases continue to rise at the current rate scientist predict that average global temperatures will rise by around 3ºC by the end of this century.Such temperatures will almost certainily melt polar icecaps, and the resulting floods might affect major cities like New York and London. "I don´t know if thre is still time to stop global warming, but we have to try," says Chugiak. "It´s everyone´s responsability. We can´t just leave it all to the politicians." So what can we do?
