Scientists have (a) — reported that the surface icecaps are (b) —. This is due to a rise (c) — atmospheric temperature known (d) — the green house effect. According to the scientists, carbon di-oxide is primarily responsible (e) — temperature rise in (f) —. The carbon di-oxide is high (g) — coal and oil (h) — burnt. The gass is accumulating in the atmosphere and (i) — temperature to rise. As a result, the polar ice in the North and south poles (j) — melting.
