▶ 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.
▶ Causes of Global Warming:
☢ Man-made Causes of Global Warming :-
- Deforestation
- Use of Vehicles
- Chlorofluorocarbon (CFCs)
- Industrial Development
- Overpopulation
☢ Natural Causes of Global Warming:-
- Volcanoes
- Water Vapour
- Melting Permafrost
- Forest Blazes
▶ Effects of Global Warming:-
- Rise in Temperature
➡ Global warming has led to an incredible increase in earth’s temperature. Since 1880, the earth’s temperature has increased by ~1 degrees. This has resulted in an increase in the melting of glaciers, which have led to an increase in the sea level. This could have devastating effects on coastal regions.
- Threats to the Ecosystem
➡ Global warming has affected the coral reefs that can lead to a loss of plant and animal lives. Increase in global temperatures has made the fragility of coral reefs even worse.
- Climate Change
➡ Global warming has led to a change in climatic conditions. There are droughts at some places and floods at some. This climatic imbalance is the result of global warming.
- Spread of Diseases
➡ Global warming leads to a change in the patterns of heat and humidity. This has led to the movement of mosquitoes that carry and spread diseases.
- High Mortality Rates
➡ Due to an increase in floods, tsunamis and other natural calamities, the average death toll usually increases. Also, such events can bring about the spread of diseases that can hamper human life.
- Loss of Natural Habitat
➡ A global shift in the climate leads to the loss of habitats of several plants and animals. In this case, the animals need to migrate from their natural habitat and many of them even become extinct. This is yet another major impact of global warming on biodiversity.
