　　Recent studies show that the earth is getting warmer. The scientists who carried out the studies say a large amount-of CO₂ in the atmosphere is the reason for the warming. CO₂ is the gas which humans and animals give off when they are breathing. It is also produced when coal, oil and other things are burnt. Scientists have warned that this kind of burning is adding too much CO₂ to the atmosphere（大气）. They believe the gas acts like a green house--the grass-topped building used to grow plants in cold weather. They say the gas is like the grass roof（房顶）of a green house, which lets in sunlight, but stops heat from running away. As a result, they say the earth becomes warmer.

　　One of these scientists, Dr. Hansen, says the weather will become so hot that some rivers will dry up. On the other hand, satellite pictures show us there is less ice in the Antarctic（南极洲）during the summer time than in earlier years. The heat would turn all the ice at both ends of the earth into water, making the oceans rise five to seven meters higher than they are now.
