Global Warming: Consequences of Global Warming

Global Warming is the gradual increase in 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. There are several causes of global warming which have a negative effect on human, plant and animal lives. These causes may be natural or might be the outcome of human activities. In order to curb the issues, it is very important to understand the negatives of global warming.

Sources of Global Warming

  1. Deforestation: It causes to increase levels of carbon dioxide to the atmosphere. Plants are the main source of oxygen. They take in carbon dioxide and release oxygen thereby maintaining environmental balance. The forests are being depleted for many domestic and commercial purposes. This has led to an environmental imbalance thereby giving rise to global warming.
  2. Volcanoes: Volcanoes emits huge amount of carbon dioxide approximately 25 million tons, therefore the entire region around the volcano is enriched in carbon dioxide.
  3. Environmental Pollution : It means Air and water pollution, It may also element causes to global warming. Because air pollution increases more carbon-dioxide.


  1. 1. Changing patterns of rainfall: Patterns of rainfall would change worldwide causing large shifts in agriculturally productive areas.
  2. Increased rate of decomposition: As a result of increased global temperature due to greenhouse effect, the dead plant matter and soil organic matter would decompose at the rate higher than normal. The decomposition shall yield more carbon dioxide, which would supplement the greenhouse phenomena.
  3. Evaporation of water from soil: Due to increase in temperature, the moisture content of soil would decrease, and so would its fertility towards many crops.
  4. Effect on human health: An increase in average global temperature is likely to increase the incidence of infectious diseases, such as malaria, schistosomiasis, sleeping sickness, dengue and yellow fever. An increase in the global temperature is suspected to extend the range of vectors the mosquitoes, flies and snails that transmit infectious disease.
  5. Effects on Wildlife: With every rise of 1°C, plant and tree species will have to move about 90 kilometres pole wards to survive. Changing rainfall patterns will compound the ecological disaster, while rise in sea levels will swamp coastal habitats.
  6. Climate effects: Work done with different climatic models shows there is scientific uncertainty about the effects of global change.
