World Environment Day (International Polar Year)

- (Genesis 8:22, The Bible ).
Our environment has been under threat for quite sometime now. Needless to say, we, the people, of this planet earth, are to be blamed.
Global warming is threatening the Earth's endurance and our very existence.
Awareness regarding the environmental crisis began way back in the twentieth century. In 1972, The United Nations General Assembly decreed that the world observe World Environment Day (WED) on June 5, each year. Accordingly, every year a different city plays host to WED and organizes an international exposition that extends a week, starting on June 5.Each year this exposition highlights a then current issue. The purpose of this observance is to not only kindle an awareness among the public about our fast deteriorating environment , but also to harness political and public support and to implement restorative action.
This year,the most peaceful country in the world, Norway, is the host.And the topic? It is ''Melting Ice - A Hot Topic?'' The focus is on climatic changes and its effects on ice and snow-covered areas of the world as it is in the polar systems that the impact of global warming has been most profound and measureable.
Norway plans to showcase the main celebrations in its eighth largest city, Tromsoe.The city, popularly known as ''The Gateway to the Arctic'' is situated north of the polar circle. In the context of the shrinking Arctic ice cap, it would appear that the place and theme are well matched indeed what better way to (celebrate) WED!
The North and South Poles are the centres of our planet's polar regions .These frigid zones are extensively covered by polar ice caps resting respectively on the Arctic ocean in the north and the Antartic continent in the south. Since the ice is more ''water ice'', the Arctic Ocean is covered by floating ice or sea ice, called the Arctic Ice pack.
In recent years there has been noticeable shrinking of polar ice. Scientists have warned that the Arctic ice cap may disappear in the next 100 years! NASA and the National Snow and Ice Data Centre together conducted a study and report that since 1978, the polar ice cap has shrunk by 30 percent. Incidentally, the Arctic summer this year was the warmest in 400 years!
The Greenland ice sheet is melting three times faster today than it was five years ago, according to a new study. The finding adds to evidence of increased global warming in recent years and indicates that melting polar ice sheets are pushing sea levels higher, the authors report. According to the study, Greenland ice loss now amounts to more than 48 cubic miles (200 cubic kilometers) each year . - John Roach (National Geographic News, 10 Aug 06).
