Global Warming is the increase of earth’s temperature because of greenhouse gases like carbondioxide, emissions from burning fossil fuels or from deforestation.
The burnt, cut down or rotted trees contribute to global warming as their stored carbon is released into the air as carbon dioxide, deforestation is responsible for about 10 percent of all global warming emissions.
Impact of Global Warming
The major impacts of Global Warming are:
- Change in Climate: Global warming cause’s climate change. The world is becoming warmer and warmer. The regional climate changes along the ecosystem could also be predicted.
- Change in Sea Level: Rise in the sea level is one of the major consequences of global warming arising out of greenhouse effect. Four major changes take place prior to this. They are: Thermal expansion, mountain glacier melting, Greenland ice sheet melting and Polar (Arctic and Antarctic) ice sheet melting. Thus, the coastal cities and ports may be submerged under sea-water. Many islands may vanish from the earth surface as well as from the world map.
- Water Balance: Although changes in sea-level have received much publicity, problems of water availability are likely to be more serious and perhaps more expensive to solve. In future, warmer world will face water crisis in some parts while in other regions it will be better than it is now.
- Human Health: The human health is put at risk because of Global warming. The warmer the earth, the more people with tropical diseases.
How to prevent Global Warming?
The problem of Global Warming can be controlled by minimizing the greenhouse gas emissions into the environment. The following preventive steps would help save the earth from the harmful effects of Global Warming.
- Laws. The Laws that governs pollution and greenhouse gases should be followed.
- Reduction in thermal power generating stations. The thermal power dependence our electricity need must be reduced. The use of fossil fuels for generating conventional energy is a major of greenhouse gases.
- We should not waste paper. We can save paper by keeping documents in electronic format and by not printing emails.
- Planting Trees. Afforestration should be encouraged as trees absorb carbon dioxide and releases oxygen.
Sharing our car. We can share our car while going to office or performing other scheduled activities. On one hand, we will save money, and on the other, we will emit less greenhouse gases.
