Many scientists believe that the Earth atmosphere is heating up rapidly, researchers and scientists believes humans are the main cause. The term globe warming another term for "global warming" is "climate change." refers to the increase in the average temperature of global surface air and oceans since about 1950, and to continuing increases in those temperatures. Emissions from human activities have caused this unnatural change. Using the latest computer models, and the latest weathering technology their forecasts are worrisome of what might global warming mean to our planet. Global warming begins when the sun’s energy, in the form of light and heat, enters the Earth. However, it rises up, escapes the earth’s atmosphere, and returns to space in the form of infrared waves. Due to the presence of greenhouse gases such as water vapor, carbon dioxide, methane, and nitrous oxide, most of this radiation is trapped in the atmosphere. This is nature’s way of keeping the Earth at a comfortable temperature; without it, this planet would be too cold to even live in. You cannot exactly say they are harmful; it's just that now we have greatly increased the amount of carbon dioxide (CO2) along with other greenhouse gases, thereby thickening the atmosphere trapping more heat and bringing up the Earth’s average temperature dangerously warmer. While the greenhouse effect is an essential environmental prerequisite for life on Earth, there really can be too much of a good thing, when human activities distort and accelerate the natural process by creating more greenhouse gases in the atmosphere than are necessary to warm the planet to an ideal temperature. Here are some of the causes of the greenhouse effect: burning natural gas, coal and oil-including gasoline for automobile engines-raises the level of carbon dioxide in the atmosphere. Some farming practices and land-use changes increase the levels of methane and nitrous oxide. Many factories produce...
