Global Warming

Increase in the global average surface temperature resulting from enhancement of the greenhouse effect, primarily by air pollution. In 2007 the UN Intergovernmental Panel on Climate Change forecasted that by 2100 global average surface temperatures would increase 3.2 – 7.2 °F (1.8 – 4.0 °C), depending on a range of scenarios for greenhouse gas emissions, and stated that it was now 90 percent certain that most of the warming observed over the previous half century could be attributed to greenhouse gas emissions produced by human activities (i.e., industrial processes and transportation)is known as global warming


Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapour, carbon dioxide (CO2), methane and ozone. Greenhouse gases are those gases that contribute to the greenhouse effect (see below). The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide.


Owing to the overall rise in the temperature, the glaciers in the Antarctic region begin to melt which has increased the overall sea level. If this situation continues, many low lying areas will submerge in the near future. Global warming also increases the occurrences of hurricanes.

There are many easy solutions to reduce global warming and its impact. First of all, people should understand the problem and take measures accordingly to save the world.
People should reduce the usage of electrical appliances which emits green house gases. For e.g. the refrigerator releases chloro fluro carbon (CFC) and the incandescent light lamp emits 300 pounds of carbon dioxide a year. This can be replaced by a compact fluorescent light bulb which saves much energy.

Follow RRR-Reduce, Reuse, Recycle. People should not dump waste products in the ground. Plant products, food waste, vegetable dump undergoes anaerobic decomposition i.e. they break down to produce methane, a green house gas instead of oxygen. Hence the product usage and wastage should be reduced or recycled for a healthy atmosphere.

Trees absorb a large amount of carbon dioxide. Many trees should be planted since they involve in photosynthesis, food preparation with the help of sunlight. During this process, trees absorb carbon dioxide and exhale oxygen. Also, existing forests should be saved and usage of plant byproducts shouldn’t be wasted

Usage of green power prevents 300 kg of carbon dioxide to be emitted into the atmosphere. The electricity obtained from the renewable resources like wind and water is called green power. The cost is also low in case of green power.

People should use only energy efficient appliances. Thermostat should be used for air conditioners since it reduces the temperature automatically.

Insulation of the ceiling of a house and power saving is the important factor to reduce global warming. The electric appliances should be switched off instead to hold it in stand by mode. This will save more power since stand by mode consumes 40% of the energy.

Consumption of organic food should be increased because organic soil absorb large amount of carbon dioxide. Buying local food reduces the consumption of fuel. Cows emits large amount of methane due to their vegetarian diet. Hence meat consumption should be reduced. Also tetra packs should be used instead of tinned food.

Periodic maintenance of the vehicles helps in efficient usage of fuel and reduces release of green house gases. Proper inflation of tyres should be done and fuel wastage should be avoided

Teach your neighborhood and friends about the cause and impacts of global warming and methods to reduce it. Conservation of forests also forms a factor to reduce global warming

i hope now you will try to stop global warming !!
