Introduction and meaning: The rise in earth’s surface temperature as a consequence of greenhouse effect is called Global Warming.
The greenhouse gases such as carbon-dioxide and other pollutants absorbs more heat from the sun then it radiates back. This causes an increase in the intensity of heat in atmosphere.
The thickening of earth atmosphere because of presence of increased carbon dioxide and other greenhouse gases is called greenhouse effect.
What causes Global Warming?
1. Deforestation and industrial emissions result to an increase greenhouse gases (such as carbon-dioxide) around earth’s atmosphere.
2. These greenhouse gases traps and absorbs atmospheric heat and ultimately causes Global warming (an increase earth’s surface temperature).
Effects / Impact of Global Warming
If Global warming continues the world would be in danger. The major effects and impacts of Global Warming are:
1. Climate Change: Global warming is causing climate change. The world’s is becoming warmer and warmer. There is also prediction of regional climate changes along the ecosystem.
2. Sea Level Change: One major consequence of global warming arising out of greenhouse effect is the rise in sea level. 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.
3. 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 wetter than it is now.
There is uncertainty regarding regional forecasts of future precipitation as warming of globe makes it difficult to predict. Also, pattern of agricultural changes, or effects on ecosystems in general are fairly unpredictable.
4. Human Health: The human health is put at risk because of Global warming. In recent years, there have been newer reports of spread of major tropical diseases with changing climate. As the earth becomes warmer, more and more people are likely to be affected by tropical diseases.
How to prevent Global Warming?
The problem of Global Warming can be controlled by minimizing the emission of greenhouse gases 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. Reduced dependence on thermal power for our electricity need would help towards reducing the quantity if carbon dioxide in the environment. 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. Trees absorb carbon dioxide and releases oxygen. Trees are helpful in reducing the problem of global warming.
- 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.

Sustainable Development Can Reduce Global Warming Essay

"Global warming is too serious for the world any longer to ignore its danger or split into opposing factions on it."
-- Tony Blair, speech, Sept. 27, 2005
According to the latest scientific data there is a direct human influence on the climate system. An upward trend in global temperatures can be clearly seen over the last three decades. The effects of this human induced climate destabilization can be seen in the present and are projected to worsen over time, regardless of the level of carbon emitted into the future. This does not mean that global and regional systems should not be overhauled to reduce carbon emissions. A rapid decrease in emissions is necessary to avert further warming of the planet and changes in the climate…show more content…
While posing significant threats to the stability of society, it is a driving force of this newfound development scheme. With changes in line with sustainable development, great gains in living conditions can be seen.
In looking at the driver of climate change, fossil fuels, an obvious need for doing away with all fossil fuels can be seen.
Just as important to look at though, are the public health benefits that come from reducing the burning of fossil fuels. Smog and airborne particulate matter are a huge health risk all over the world, from the smog filled skies of Beijing to the United States, where in 2013 118 of the 231 counties in the United States exceeded the EPA’s allowed level of ozone. These dangers are a direct result of burning fossil fuels. Switching to power-generation systems that do not emit will not only slow global warming, it will directly save lives and promote healthier activities.
The alleviation of poverty is one of the United Nation’s direct responsibilities. Taking a look at poverty one will find that about 1.3 billion people in the world do not have access to electricity. One solution to this would be to build large centralized coal plants, which would be the centers of massive electricity transportation networks. This inefficient and unsustainable system is currently in place in much of the developed world. However other solutions exist. There has been a great deal of work done on the link between renewable energy and
