    Unusual incidents are being reported across the Arctic. Inuit (因纽特人) families going

off on snowmobiles to prepare their summer hunting camps have found themselves cut

off from home by a sea of mud. There are also reports of sea ice breaking up earlier than

usual, carrying seals beyond the reach of hunters. Climate change may still be a rather

abstract (抽象的) idea to most of us, but in the Arctic it is already having great effect-

if summertime ice continues to shrink at its present rate, the Arctic Ocean could soon

become almost ice-free in summer. The knock-on effects (连锁反应) are likely to include

more warming, cloudier skies and higher sea levels. Scientists are increasingly eager to find

out what's going on in the Arctic.

    For the Inuit the problem is urgent. They live in unsteady balance with one of the toughest

environments on earth. Climate change, whatever its causes, is a direct danger to their way

of life. Nobody knows the Arctic as well as the locals, which is why they are not content

simply to stand back and let outsider experts tell them what's happening. In Canada, where

the Inuit people are trying hard to guard their hard-won autonomy (自治权) in the country's

newest land, Nunavut, they believe their best hope of survival in this changing environment

lies in combining their ancestral (祖先的) knowledge with the best of modern science. This

is a challenge in itself.

    The Canadian Arctic is a vast, treeless polar desert that's covered with snow for most of

the year. Adventure into this area and you get some idea of the hardships facing anyone who

calls this home. Farming is out of the question and nature offers few pickings. Humans first

settled in the Arctic a mere 4,500 years ago, surviving by taking advantage of sea first. The

environment tested them to the limits: sometimes the settlers were successful; sometimes they

failed and disappeared. But around a thousand years ago, one group appeared that was uniquely

well adapted to deal with the Arctic environment. These Thule people moved in from Alaska,

bringing dogs, iron tools and the like. They are the ancestors of today's Inuit people.
