Global Warming
Global warming is a gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
Global warming is the phenomenon of a gradual increase in the temperature near the earth’s surface. This phenomenon has been observed over the past one or two centuries. This change has disturbed the climatic pattern of the earth. However, the concept of global warming is quite controversial but the scientists have provided relevant data in support of the fact that the temperature of the earth is rising constantly.
Man-made causes of global warming are as follows:
- Deforestation
- Use of vehicles
- Chlorofluorocarbon
- Industrial Development
- Agriculture
- Overpopulation
Natural causes of global warming as as follows:
- Volcanic eruption
- Water vapour
- Melting permafrost
- Forest Blazes
