Most scientists agree thet the world's climate is getting warmer and you can already see the difference in Greenland For example,small icebergs - about size of city buses - are floating near to coast.They have broken off from much larger near to the coast.They have broken off from much larger areas of ice further out in the ocean because of the change in temperature. Furthermore,the huge sheet of ice which covers Greenland is shrinking by about 75 cubic kilometreseach year. If all of Greenland's ice melted,sea levels across the word would rise by 7.5 metres
