Global Warming: A Deadly Threat for Human Life

The recent activity in Iceland-Volcano brought the whole world to a grinding halt. This was the most recent reminder of nature's power, and shows how feeble human beings are in front of mother nature; however, advanced the human race has become in technology. The natural catastrophes similar to above are grim reminders to respect nature.

What is Global warming: There is a perceptible change in the average temperature of the atmosphere through out the world. This increase in the average temperature of Earth's atmosphere is known as GLOBAL WARMING. The summers are becoming hotter and longer, and the winters are turning out to be more freezing (recent increased snowfall witnessed in Northern Hemisphere) and longer. Not to mention that the spring and autumn are becoming shorter. Let us try to understand what has caused this change in climate, and what are the effects of this change?

Earth is the only planet suitable to human life known to us in the Universe. Other planets are either too hot or too cold to support the life. What sets planet Earth apart is the Earth's atmosphere, and Green House Effect. Planet Earth receives the heat from Sun in form of radiation during the day. The heat radiation from Sun enters the earth's atmosphere, and gets reflected back from the earth surface. Earth's atmosphere consists of different gases, and some gases' atoms have the property to trap the heat; these gases are termed as green house gases (e.g. CO2, CH4 etc.), and the phenomenon of heat-trapping is called the Green House Effect. Owing to the Green House Effect, a part of the reflected heat is trapped in the atmosphere. The heat trapped by the atmosphere during the day saves the earth from cooling down to the freezing temperate during night when there is no heat radiation received by Earth.

This is a very delicate balance and directly depends on the quantity of Green house gases in the atmosphere. Higher the percentage of the green house gases in atmosphere composition the higher the amount of heat will be trapped in atmosphere; therefore results an increase in the temperature of the Earth. Some of the major green house gases are Carbon Dioxide (CO2), Carbon Monoxide (CO) and Methane (CH4).

The major human activities contributing to a higher percentage of green house gases are:

There are two significant methods that prove that the carbon dioxide in the atmosphere comes from human activity. An isotope called carbon-14 is formed high in the atmosphere when radiation from space collides with nitrogen-14 (“Human Caused Global Warming”). Thus, carbon dioxide in the atmosphere with a high level of carbon-14 originated not from
