Global Warming

The term global warming mean increase in greenhouse effect. Global warming occurs when carbon dioxide and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface.  this radiation would escape into space but these pollutants which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter.

Global warming has emerged as one of the major threat to our planet in this century. It has been proved that due to the increase of the greenhouse gases in our outer atmosphere. The earth’s temperature has warmed by 0.74°C over the last 100 years, leading to floods, famines, droughts and cyclones among other natural disasters.

Global warming is the center of attention for every country. Global warming is a phenomenon in which the temperature of the earth rises with time. The rise in temperature occurs due to greenhouse gasses that are emitted on regular bases, the burning of fossil fuels, smoke discharge from the factories etc.

The human activities like burning of fossil fuels, excessive smoke discharges from factories and the depletion of forests have led to an increase in the concentration of the greenhouse gases, mainly carbon dioxide, methane and nitrous oxide, in the earth’s outer atmosphere which are responsible for trapping excessive heat inside the environment and thus increasing the overall temperature of the earth, leading to the phenomenon of global warming

Moreover the major part of the Pakistani land is dry and barren because of the great variability in the climate. The major water resource of Pakistan is the melting snow from the Himalayan glaciers, as well as the heavy monsoon rainfalls.

Although Pakistan itself contributes very little to the overall emissions of the greenhouse gases, yet it remains one of the most severely hit countries of the world by the process of global warming. Pakistan’s economy has been crippled heavily by devastating and repetitive floods during the last decade.

The nation is facing ever-rising temperatures, drought and flooding that threaten health, agriculture, water supplies and hopes for development of a society that ranks in the bottom quarter of nations, based on income per person.

How to control Global Warming?

Firstly replace one regular light bulb with a compact fluorescent light bulb will save 150 pounds of carbon dioxide a year.

 Secondly walk or do cycling  more you'll save one pound of carbon dioxide for every mile you don't drive.

Thirdly plant trees a single tree will absorb one ton of carbon dioxide over its lifetime.

Lastly avoid plastic bags a single tree will absorb one ton of carbon dioxide over its lifetime.

Global warming is an alarming situation for the nation. As Pakistan is already a source stressed country it is the duty of every citizen to feel their responsibility and act like a responsible citizen.
