Save the world: Global Warming

What is Global Warming:

An increase in the average temperature of the earth’s atmosphere.

Global warming is caused by the gases in the atmosphere such as carbon dioxide and methane, which form a sort of layer over the Earth, trapping in heat that would normally escape the atmosphere. The leading greenhouse gas is carbon dioxide, a pollutant emitted from the burning of fossil fuels, such as coal, oil, and natural gas.

The increase in global temperatures brought about by the increased emission of greenhouse gases into the atmosphere.

What is Greenhouse effect:

The greenhouse effect is a naturally occurring process that aids in heating the Earth’s surface and atmosphere. It results from the fact that certain atmospheric gases, such ascarbon dioxide,water vapor, and methene, are able to change the energy balance of the planet by absorbing longwave radiations emitted from the Earth’s surface. Without the greenhouse effect life on this planet would probably not exist as the average temperature of the Earth would be a chilly -18° Celsius, rather than the present 15° Celsius.

Greenhouse gases:

1) carbon dioxide CO2

2) Methene CH4

3) Nuterios oxide N2O

4) ChloroforoCarbon CFxCLx

5) Ozone O3

The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.

he US produces far more carbon dioxide than any other country in the world. According to the latest figures by the Department of Energy, the US produces 22% of all CO2 emitted into the atmosphere, at 5,912.21 million metric tons in 2004. That is more than China, and India together (17% and 4.1% respectively), more than Russia (6%), Japan (4.7%), Australia (1.4%) and the whole of Europe put together (17.2%). In the United States, the major sources of CO2 emissions stem from burning fossil fuels, like coal, natural gas, and oil.

Things to take care:

1) A well-tuned car with properly inflated tires burns less gasoline—cutting pollution .

2) wind and solar power, can reduce our reliance on coal-burning power plants, the largest source of global warming pollution in the world.

3) An energy-efficient electronic and appliances will save you money on your electricity bill and cut global warming pollution.

4) Producing new paper, glass, and metal products from recycled materials saves 70 to 90 percent of the energy and pollution, including CO2,

5) Educate your community about how it can cut global warming pollution.
