Most scientists agree that the world’s climate is getting warmer and you can already see the difference in Greenland. For examPle, small icebergs about the size of City buses ._ are Hoating near t0 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 kilometres each year. If all of Greenland’s ice melted, sea
levels across the world would rise by 7.5 metres.
