One of the most reliable indicators of global warming is the rate at which icebergs and glaciers melt. In a general sense, permanent glaciers are getting smaller and fewer. For example, projections show that 70% of the glaciers in the Alps will melt during the 21st century. The rate at which the Greenland ice sheet melts has doubled during the last 10 years. When the effects of global warming were not as clear as they are now, the predicted lifespan of Greenland glaciers was longer. But now protection shows they will melt completely in only 1000 years. With all tsih ice mass melting, oceans are rising on average of 2,5 mm every year.
By the ende of next year, we will understand a lot more about global warming and its consequences because in 2007 experts from various universities around the world will initiate a study that will produce a comprehensive report on melting ice over the last 50 years.
2007 is important because around 50.000 scientists from 60 countries have declared it International Ice Year. For now, scientists are preparinh for Ice Year, which has been declared only twice before; in 1882 and 1932. In 2007, the world’s attention will again be directed towards the poles in an attempt to understand the earth’s geographical structure, but this time the purpose is to research the effects of global warming. It is obvius that these research attempts will not remove the danger. So, to combat this irreversible change, public awareness campaigns will also be initiated.
