CONSEQUENCES OF GLOBAL WARMING

Greenhouse gases can retain in the atmosphere for a long period of time ranging from decades to million of years. Human preventing measures can't even mitigate its effect on the earth. Therefore, its effects can be prevailed on earth and that may harm whole of the human civilization.

1. Melting of polar ice caps
The most ongoing issue that is taking place globally is melting of the ice caps. It is a four pronged danger.
• Rise in sea level all over the world. It is estimated that if all the glaciers that exist today melt, then there will be increase in the sea level by 230 feet.
• Imbalance in the global ecosystem. The melting ice caps are fresh water and when they mix with the ocean water, desalinization of water takes place. It shuts down or increases the irregularity in the smooth functioning of ecosystem.
• Extinction of weaker species of animals. As evidenced by Darwin, only the fittest and the most adaptable species of animals will survive in the environment of increasing temperature and changing landscapes. Therefore, there is an extinction of those species which can’t adapt to the changing environment of the earth.
• The melting of ice caps allows much more heat to enter this atmosphere. Since ice caps are white in colour, they reflect most of the sunlight back to atmosphere. There are only seas to reflect and absorb the sunlight in absence of seas. Therefore, most of the sunlight enters into the earths atmosphere and is trapped, hereby rising the temperature of the earth.

2. Economic consequences
Global warming has an obvious effect on the human and environment. In addition to these, it has an equal effect on the economic sector of countries of the world. Money is spent to treat and control the diseases, billions of dollars is destroyed during hurricanes and again a lot of money is required to renovate all these. So, it is also a cause for increasing recession of the world.

3. Increase in probability of droughts and heat waves

Global warming may wet some areas of the earth. Nevertheless, other areas may have increased probability and intensity of droughts and heat waves. The most affected region due to this is the country Africa which has born the adverse effects and these have exacerbated its condition.

4. Warmer waters and more hurricanes
Global warming is accompanied by increase in the temperature and this results in more possibility of hurricanes as in 2004 and 2005.

5. Spread of diseases
As the temperature of the earth increases, the earth plunges into the threatening situation of global warming. As the northern hemisphere gets warmed up, disease carrying insects migrate to the north bringing diseases with them like plague and malaria. Sometimes, these diseases become epidemic and may place the whole human civilization in danger.
