Read the passage below carefully and choose the correct answer a, b, c, or d.
Scientists believe that something very serious is happening to the Earth. It is becoming warmer. Scientists predict that there will be major changes in the climate during the 21st century. Coastal water will have higher temperatures. This will have a serious effect on agriculture. The farmer will have trouble producing good crops. In warm regions, the weather will be too dry. The amount of water could decrease by 50 percent. This would cause a large decrease in agricultural production.
World temperature could increase from 1.5 to 5.6 degrees Celsius by the middle of the 21st century. And the increase in, temperature could be even greater in the Arctic and Antarctic regions. A rise in temperature could cause the great ice sheets to melt, which, in turn, would raise the level of the oceans by one to two meters. Many coastal cities would be underwater. Why is all this happening?
The Earth and its atmosphere are kept warm by the Sun. The atmosphere lets most of the light from the Sun pass through to warm the Earth. The Earth is warmed by the sunlight and sends heat energy back into the atmosphere. Much of this energy escapes from the Earth’s atmosphere. However, some of it remains. Gases such as carbon dioxide, ozone, and water vapor absorb this energy and create more heat. Then this heat is sent back down to Earth, and the Earth becomes warmer.
The melting of the polar ice sheets will probably lead to ________.
