Global Warming

The theory of Global Warming is a term used to describe an increase, over time, of the average temperature of Earth's atmosphere and oceans. Global warming theories strive to give an account for the ascending average global temperatures since the late 19th century, and review the scope to which the effects are owing to human causes. Most supporters believe that human CO2 emissions are to blame for the warming, causing a Greenhouse Effect, while others attribute it to methane. There are also those that blame the hole in the ozone layer that lets in more sun.

Most of these gases are being utilized for vital functions. For instance, hydrogen is liberated by volcanoes, which can give energy 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. (www.pewclimate.org)Not only do those gases make up our atmosphere, but they also keep the temperature of the earth stable.

By adding collectively oxygen as well as taking away carbon dioxide this makes the earth to be cooler than it would actually 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.

If sufficient gases are not found in the atmosphere then it would be too cold. But if several gases are released into the air, then we have the problem of heating up things.

The earth's atmosphere comprises of five layers of gases that operate as a blanket sheltering 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. (www.pewclimate.org). This is for the motive that it acts like greenhouse windows by leasing in sunlight to warm the surface in addition to air, and grasp in the majority of the solar generated warmth.

The greenhouse gases comprise of oxygen, carbon dioxide, nitrogen, methane, ozone and water vapor, as well as other atmospheric gases. Those greenhouse gases become the reason for the greenhouse effect by taking into plus absorbing solar power. For devoid of the greenhouse effect, the planet ought to be inhospitable to life for the reason that the surface temperature of earth's surface should be cooler by 63 degrees F. (yosemite.epa.gov)This world signifies the standard temperature must be 19 degrees C which causes the earth to be unproductive.

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 ensnared in the environment than required. Carbon dioxide is the most important gas that humans have ...
