Hot and Warm..

Asslamaulaikum my friend...

Do u know about earth warming ? What is earth warming ? ..So today i want to share about what i know.Global warming is an average increase in the temperature of the atmosphere near the Earth's surface and in the troposphere, which can contribute to changes in global climate patterns. This process may last for an extended period (decades or longer). The "greenhouse effect" refers to the natural phenomenon that keeps the Earth in a temperature range that allows life to flourish. The sun's enormous energy warms the Earth's surface and its atmosphere. As this energy radiates back toward space as heat, a portion is absorbed by a delicate balance of heat-trapping gases in the atmosphere—among them carbon dioxide and methane—which creates an insulating layer. With the temperature control of the greenhouse effect, the Earth has an average surface temperature of 59°F (15°C). Without it, the average surface temperature would be 0°F (-18°C), a temperature so low that the Earth would be frozen and could not sustain life. Global warming" refers to the rise in the Earth's temperature resulting from an increase in heat-trapping gases in the atmosphere.

Scientists have concluded that human activities are contributing to global warming by adding large amounts of heat-trapping gases to the atmosphere. Every time we drive a car, use electricity from coal-fired power plants, or heat our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the air. The second most important source of greenhouse gases is deforestation, mainly in the tropics, and other land-use changes.

The impacts of global warming on us may be felt gradually. The impacts shall be felt in many aspects such as health, forests, crops yield, water supply, erosion of beaches, loss of habitats and species.

There are many ways we can do to reduce global warming. Governments can adopt a range of options for reducing greenhouse gas emissions, including

* increasing energy efficiency standards
* encouraging the use of renewable energy sources (such as wind and solar power)
* protecting and restoring forests, which serve as important storehouses of carbon
* disaster mitigation – flood warning and prevention

Individuals can reduce the need for fossil fuels and often save money by

* driving less and driving more fuel-efficient and less-polluting cars
* using energy-efficient appliances
* using less electricity in general
