Scientists have recently reported that (a) — surface Ice caps are (b) —. This is due to a rise (c) — atmospheric temperature known (d) — the greenhouse effect. According to the scientists, carbon dioxide is primarily responsible (e) — temperature rise in the (f) —. Carbon dioxide is high when coal and oil (g) — burnt. The gas is accumulating (h) — the atmosphere and causing the temperature to rise. As a result, the polar Ice in the North and South poles (i) — melting. We should maintain the ecological (j) — of the environment.
