Global warming refers to the sustained increase in the average temperature of the earth’s atmosphere. In simple words, the phenomenon of warming of the planet Earth is known as global warming.

The chief indicators of the global warming are as under:

• Ozone Depletion
• Greenhouse effect
• Burning of Fossil fuels like coal, oil and natural gas which release greenhouse gases in the atmosphere. • Rapid industrialisation
• Motor vehicle exhaust

The climate history of the earth has always fluctuated. There have been Ice Ages as well as the periods of great warmth, like when dinosaurs roamed the planet. So why is everyone concerned about the climate change now? Firstly, this changing climate is man-made. Secondly, the rate and speed at which the climate is changing has never occurred before. The climate used to change over a period of thousands of years. Scientists generally agree that the Earth’s surface has warmed by about 1 degree Fahrenheit in the past 140 years. A recent report predicts that the global temperature could rise between 1 degree Celsius and 6 degree Celsius by the ends of this century. That is some serious warming. 

One of the biggest issues we are facing now is global warming. Its effects on animals on animals and on agriculture are needed frightening. The effects on the human population are even scarier. The facts about global warming are often debated. But unfortunately, even if we disagree about the causes, global warming effects are real, global and measurable. Let’s first discuss the causes of global warming and then its effects on the globe.

Our ever increasing addiction to electricity from coal burning power plants release enormous amounts of CO2 into the atmosphere. 40% of US CO2 emissions come from electricity production. Burning of coal accounts for 93% of emissions from the electric utility industry. Every day, more electric gadgets flood the markets. Without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply.

Our modern car culture and appetite for globally sourced goods is responsible for about 33% of emissions. With our population growing at an alarming rate, the demand for more cars and consumer goods is increasing. It means that we are increasing the use of fossil fuels for transportation and manufacturing. Our consumption is outpacing our discoveries of ways to mitigate the effects. There is no end in sight to our massive consumer culture.

Methane is another extremely potent greenhouse gas. When organic matter is broken down by bacteria under oxygen-starved conditions (anaerobic decomposition) as in rice paddies, methane is produced. The process also takes place in the intestine of herbivorous animals. With the increase in the amount of concentrated livestock production, the level of methane released into the atmosphere is increasing.

The use of forests for fuel, both wood and for charcoal is another major cause of global warming. Our appetite for wood and paper products contributes to the mass...
