The term Global Warming is getting much attention these days due to its possible hazards in coming time. It is certainly an aspect of climate change. In simple words Global Warming is the increase in the temperature of the Earth’s atmosphereand the area of concern for scientists is the rate at which the temperature is increasing. It is an issue that is being widely discussed all around the world and scientists are figuring out the causes of Global warming. To know what causes Global Warming lets get familiar with two more terms that are Greenhouse Gases and Green house Effect.

Greenhouse Gases, Greenhouse Effect and the cause of Global Warming

The greenhouse effect is that process where thermal radiation from the Earth surface is absorbed by greenhouse gases. Greenhouse Gases are those naturally occurring gases that are required to create Greenhouse Effect. Earth requires GreenhouseEffect to keep the surrounding warm enough to support life. The effect of greenhouse gases (GHGs) emitted by humans is the cause of Global warming.

In Detail when sun rays reach the surface of earth, a proportion of them is absorbed by the Earth and warms the Earth. Now, the rest of the sunlight which is not absorbed by the Earth is radiated back to the atmosphere at a longer wavelength then the sunlight and are absorbed by Greenhouse Gases. This absorption of thermal radiation by greenhouse gases is called greenhouse effect which further warms the Earth and the end result is that the Earth temperature gets higher than it would be if warming by solar radiation were the only heating mechanism. The increase in temperature of Earth is thus called Global Warming.

The Greenhouse Gases are also abbreviated as GHG and they affect the temperature of Earth by keeping the Earth warm. In Global Warming, the problem comes in the scene when scientist determined that due to some human activities there is an increase in the Greenhouse Gases and thus causes Global Warming. The excessive amount of Greenhouse gases in the atmosphere trap the heat that would otherwise exit in the space.

Thus, Global Warming of the Earth Surface is supposed to be the outcome of increased greenhouse effect which is further is the result of increased greenhouse gases due to human activities.

In our day to day life, we people in variety of ways emit greenhouse gases that are responsible for the cause of Global warming. Most of these appear from factories and electricity production, combustion of fossil fuels in cars. Following are the several greenhouse gases that mainly contribute in global warming:

Carbon dioxide (CO2)MethaneNitrous oxideWater vaporChlorofluorocarbons

The main source of greenhouse gases is the combustion of fossil fuels for human use. The carbon dioxide which is also called CO2, produced from this combustion of fossil fuels combined with deforestation leads to higher carbon dioxide concentration is the main cause of Global warming. Deforestation is also a source of greenhouse gases, which further becomes cause of global warming because if there are fewer trees, it means a reduced amount of carbon dioxide conversion to oxygen.

A study revealed that the atmospheric concentration of carbon dioxide has increased by 31 percent during the 150 years of the industrial age and at the same time the level of atmospheric methane has climbed by 151 percent, which is released from agricultural activities such as from digestive systems of grazing animals and growing rice.

Atmospheric concentration of nitrous oxide (N2O) has been increased due to some agricultural activities such as the use of fertilizers and gases used in refrigeration system and industrial process also lead to higher concentration of nitrous oxide.

International Panel on Climate Change or IPCCis a group of scientists formed to bring all the information regarding Global Warming such as cause of Global warming and effects or dangers of global warming. The IPCC releases a report about global warming after reviewing the latest findings by scientists every few years.

Higher concentration of greenhouse gases leads to a considerable warming of the earth which is called global warming global warming or we can say that emission of greenhouse gases by human activities what that causes Global Warming.

We humans are habitual by nature and it’s hard for us to give up our automobiles, trains, buses or any agricultural or industrial activity. However, as we created a cause of global warming then we have to find out the way to slow down the process of Global warming.

These days, there seems to be a lot of controversy about Global Warming.

Some say that Global Warming is a fact, others say it’s not. But regardless of whether or not Global Warming is a fact, let’s step aside from the arguments on the subject, and take a common-sense approach.

In this article we will take a look at some of the issues involved.

What is Global Warming?

We can take a look at the definition of global warming – without taking sides or getting into vested interests, political motivations, reasons, or causes.

The definition of global warming in its purity is “an overall increase in world temperatures.” As you can see, whether this has to do with greenhouse emissions, or whether it is caused by a natural phenomena, has no bearing on whether there is an average temperature increase.

Is There an Overall Increase in World Temperatures?

Alright, now we can take a look at what scientists say about world temperatures.

Again, we are going to leave out the reasons why, and simply look at whether or not the Earth’s general temperature is rising.

According to NASA scientists, the average temperature of the earth rose by one degree Celsius, over the last century. This is based on actual measurements taken with exact measuring instruments.

Another report, compiled and submitted by 600 scientists from the Intergovernmental Panel on Climate Change, issued the following statement:

“Warming of the climate system is unequivocal.”

These 600 scientists sifted through thousands of studies and reports, in order to come to the above conclusion.

Even scientists who are “opposed” to the global warming theory are not contradicting the fact that the earth’s temperature is rising. These scientists are only saying that global warming is a natural phenomena, and is not caused by man.

The Causes of Global Warming There are several factors that could contribute to or influence global warming.

Greenhouse gases are gases that prevent heat from escaping from the Earth’s atmosphere. A few examples of greenhouse gases are:

Carbon Dioxide – A minor but important part of the Earth’s atmosphere. Carbon dioxide prevents heat from escaping the earth, by blocking the infrared radiation reflected off the Earth’s surface from leaving the atmosphere. Methane – A gas produced through the decomposition of waste (in landfills, animal waste, and decomposition of food in human and animal digestive systems). It is created by the production and distribution of natural gas, oil and coal. It is also is produced by incomplete fossil-fuel combustion. Nitrous Oxide – Another gas produced through the use of commercial fertilizers, natural fertilizers, and fossil fuel combustion (cars, airplanes, and conventional power plants, to name a few). Chlorofluorocarbons – Commonly referred to as CFC gases, these are produced primarily by our industries, and are used for products such as, styrofoam, spray-can propellants, refrigerants, electronic circuit boards, and many more. Water Vapor – This is a completely natural gas, caused by the sun evaporating water from our oceans.

As you can see, carbon dioxide, methane, and nitrous oxide are produced mainly by human resources, whereas chlorofluorocarbons are exclusively produced by industrial installations.

Out of all the above, interestingly enough, the greenhouse gases which have the largest effect on global warming are water vapors. This fact will no doubt please all critics of the “global warming theory”.

You have to keep in mind, however, the cyclic effect of global warming. A slight increase in temperature will increase the amount of water vapor in the atmosphere, which in turn will increase the temperature, and so on. Thus, a slight effect created by other greenhouse gases has a much larger impact, due to the creation of additional water vapor in the atmosphere.

Greenhouse Gases: Facts and Figures

let’s go over some facts and figures here. Again, keep in mind that these are measurements taken by scientific tools. They are not statements for or against global warming.

The amount of carbon dioxide in our atmosphere has increased by 25 percent since the early 1800s. Ten percent of this increase has occurred between 1958 and the present day. There are two main factors that responsible for the increase of carbon dioxide. The leading cause is the burning of fossil fuels. Next in line is deforestation. Methane content in the world’s atmosphere increases at a rate of 0.6 percent per year, by current measurements. The atmospheric methane content is now more than twice as high as it was before the Industrial Age, which started in the early 1800s.

The Effects of Global Warming

I am not the doom-and-gloom sort of person, so I am going to spare you the details here. But I do have an opinion on this subject, so I will share it with you.

Regardless of whether the globe is warming or not, it is simply common sense to take care of the environment you live in.

The plain truth of the matter is that carbon monoxide is unhealthy, methane makes for unpleasant breathing, and nitrous oxide in the atmosphere is no laughing matter.

While the lack of ozone might make for faster tanning at the beach, the long term effects are not as desirable.

What You Can do About Global Warming

Believe it or not, you are important – what you do and say is listened to by others, and does make a difference. It doesn’t require a lot of effort to do something about conditions in the environment. A little extra care will go quite a long way. Many are already doing it, and all of us need to get aboard.

It starts as simply as recycling your waste, saving energy where you can, or even planting a tree.

A great way to reduce pollution is the use of solar power. 75% of the average home’s energy consumption is for hot water and heating. The most economical, effective, and inexpensive way of using solar power is through the use of solar heating, and solar hot water heaters.
