Global Warming

Introduction

The atmosphere is somewhat that is following us day after day, but do we actually think about the changes that take place in it. Day after day gases are on the loose into the air by every living material. The gases in the air are used for several significant things.

For example, hydrogen is released by volcanoes, which can give power to the cell; photosynthesis has evolved to take the gas carbon dioxide and create food and release oxygen; nitrogen is a gas used in our air, oceans, and solid earth, as an essential part of living things.

Carbon dioxide is also involved in processes where it is stored as limestone and marble, as gas plus oil and coal, and is in organic material in the soil. Not only do those gases make up our atmosphere, but they also keep the temperature of the earth stable. Carbon dioxide soaks up the energy that would or else break away from the earth.

By adding together oxygen and taking away carbon dioxide this makes the earth to be cooler than it would or else be. Those are just two of the several gases that make up the atmosphere we live in today. The temperature in our earth is directly determined by those five gases.

The earth's atmosphere is made up of five layers of gases that act as a blanket covering the earth. This blanket keeps in some of those gases to keep the planet warm. This effect in easy word is called the greenhouse effect. (Jonnes, 64-67)This is for the reason that it acts like greenhouse windows by letting in sunlight to warm the surface and air, and hold in most of the solar generated heat.

The greenhouse gases comprise of oxygen, carbon dioxide, nitrogen, methane, ozone and water vapor, as well as other atmospheric gases. Those greenhouse gases cause the greenhouse effect by capturing and absorbing solar power. For without the greenhouse effect, the planet should be inhospitable to life for the reason that the surface temperature of earth's surface should be cooler by 63 degrees F. This world mean the average temperature should be 19 degrees C which causes the earth to be barren (Jonnes, 64-67).

Several scientists believe that the increase in temperature is caused by humans. The greenhouse effect increases for the reason that of the burning of fossil fuels such as natural gases, oil, and coal. Those cause more heat to be trapped in the atmosphere than needed. Carbon dioxide is the most important gas that humans have an effect on. It has increased by nearly 30% since 1700 for the reason that of human destruction's. (Weir, 58-64)

The quantity of fossil fuels we burn annually has increased dramatically. Amid 1850 and 1950 60 million tons of fossil fuels were burned. At present the world burns at least five billion tons of fossil fuels annually. This means that we are adding amid 15 and 20 billion tons of carbon dioxide into the atmosphere every 12 months (Jonnes, ...
