प्रश्न
State the effects of greenhouse gases on the atmosphere.
उत्तर
Effects of global warming
- Rise in sea level: Due to global warming, glaciers and polar ice caps have started to melt, and gradually this may lead to an increase in the sea level. This will in turn flood several coastal areas in countries such as India, Bangladesh, the Netherlands, and the Maldives.
- Global warming will cause more water to evaporate from water bodies, thus forming more water vapour. Because water vapour also contributes to the greenhouse effect, global warming will further increase.
- Global warming can lead to changes in the rain pattern and thus shift in crop zones. For example, wheat-producing zones will shift from Russia and Canada to the less fertile polar regions.
- Change in rain patterns due to global warming will also affect trees and plants in forests which are natural habitats of wildlife. With the destruction of forests, many species of wildlife will also begin to die out.
