Today, the need of the hour is a proper understanding of the causes and effects of 'Global Warming'. My definition of Global warming is:
"It is the process of converting Mother Earth into planet Venus"
Let us take a look at the effects of global warming so that we can expect a tinge of seriousness in us when we study the causes.
Can you imagine pushing your life on Venus, which is often referred to as the Sister planet of Earth, that has a surface temperature of about 500 degree Celsius?? This is what is exactly happening to our Earth. The Earth's average surface temperature has risen by 2 C` in the past 500 years, which may sound small considering the time it has taken to rise from 13 C` to 15 C`. But, it has a number of hazardous effects on Earth's health. The rising global surface temperature is the main cause for melting of polar ice caps, which house some of the largest glaciers on Earth. This has triggered the increase in the sea levels. If this state continues, we can be sure cities like Chennai and New York will turn into civilized seabed 30 years from now. The problem with Global warming is that it can't be completely controlled because the temperature has already risen and started a chain reaction in the earth's atmosphere as a result of which the amount of Greenhouse gases present in earth's atmosphere is steadily increasing. This means we can expect the temperature to increase at a rate faster than the one at which it has been moving all along.
Now, it's necessary to posses some knowledge about the causes of Global warming.
There are certain gases in the atmosphere like carbon-di-oxide and methane, which are otherwise known as Greenhouse gases. These gases are capable of allowing the infrared radiations emitted by the sun into the earth's atmosphere but do not allow the radiations reflected back from the Earth's surface out of the atmosphere. With no way out, the absorbed heat starts increasing the temperature of the atmosphere which causes a disturbance in the troposphere, the lowest layer of the atmosphere. This leads to a thermal imbalance in troposphere that once again excites Greenhouse gases and the whole process takes place again in a cycle, which ends only when Earth's life comes to a hot end. In addition to the amount of Carbon-di-oxide present in the atmosphere, the motor vehicles we use, which run on petroleum products, emit a large volume of the treacherous gas that is enough to take the average surface temperature of the Earth to alarming values. Thus, in order to keep the Earth alive for years to come, switching over to battery-powered vehicles is an option we have in front of us today, though it sounds quite tough. Burning fossil fuels adds massive volumes of Greenhouse gases to the atmosphere. But, without coal, which is one of the fossil fuels, the thermal power plants we have would run out of feedstock. Since even a day without power has now become unimaginable, combustion of fossil fuel is a necessary evil. But, we always have the alternatives in the form of renewable resources like wind energy, hydro energy and solar energy. Thus, our motto to save Earth is "When we can, we should". When we can make use of renewable energy sources, we should make good use of them.
Our Mother Earth isn't just a clump of rocks, clay and sand. It's the only place in the vast universe, as far as we know till now, which is highly generous to support our lives. You might find Earth very warm few years from now. Don't think that is because of your realization of Earth's love for you. It would actually be a sign of danger that resulted from all the anti-Earth activities we carried out in the past. It's Global Warming at our doorstep. It's late now. Let us rectify our mistakes before it becomes too late. Responsibility is now in our hands. Save Earth. Save yourself.

Remember this hari "It is better late than never"... Hope people realises what they have in the near future left for the next generation
