what is global warming...
Answers
Answer:
a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.
Explanation:
Answer:
Global Warming
Global warming is the phenomenon of the increase in the temperature of the atmosphere due to the presence of excessive greenhouse gases. These harmful greenhouse gases are emitted by the burning of fossil fuels.
Effects of global warming:
Global warming will results in the melting of the polar ice caps and raise the ocean level which will submerge islands and coastal lands. Due to extreme climatic conditions, people in many regions will be displaced. There will be mass migration as people look for habitable places for resettlement.
Global warming would cause unpredictable rainfall. A sudden flash flood will be followed by a period of drought. This will cause scarcity of drinking water and irrigation for cultivation leading to worldwide food scarcity.
The burning of fossil fuels increases global warming and also depletes the ozone layer which protects us from the harmful effects of UV rays of the Sun. This will increase the cases of skin cancer.
Global warming would cause unpredictable rainfall. A sudden flash flood will be followed by a period of drought. This will cause a scarcity of drinking water. The shortage of water for irrigation will lead to the failure of agriculture and cause worldwide food scarcity.
Prevention of Global Warming:
The catastrophic consequences of Global Warming can be mitigated by preserving the natural ecological system, shifting to sustainable development, and using more environmentally friendly energy.
Planting more trees will reduce the amount of harmful carbon dioxide gas in the atmosphere and reduce global warming. We need to shift to alternative energy instead of burning fossil fuels like coal and petroleum products. The burning of fossil fuels increases global warming and also depletes the ozone layer which protects us from the harmful effects of UV rays of the Sun.
The increase of harmful greenhouse gases will also result in acid rain. The acid rain will kill marine life and corrode buildings and monuments.
Proper treatment of industrial waste before they are dumped and using renewable energy, electric, hydro and solar energy will help us to reduce the danger of global warming. Urgent steps must be taken to reduce exhaust emissions from motor vehicles, power plants, factories, and industries. Global warming needs urgent global actions to save and preserve life on Earth.
