Introduction

We used to living in a green planet. She was a beauty and huge resources. And when the planet's resources and environment gradually disappearing gradually bad until threaten our life even life. Global warming is an important fact. What is the global warming? It is just that we were stuck in a warm environment and air. For some people, it caused trouble and threats. But for others it is always an absurd deception.
In my post I argument whether global warming alued and necessity. why need us to stop it? And what is the risk of Global Warming? Who or what cause Global Warming?

Factors cause Global Warming

Humans burning of fossil fuels such as coal and oil and natural gas in nearly a century. A large amount of carbon dioxide emissions of greenhouse gases. These greenhouse gases to the shortwave radiation from the sun has high permeability. The longwaves radiation reflected on the Earth that highly resorptive include invisible electromagnetic pollution which call "greenhouse effect" also can cause global warming. The forests in the world can be divided into frigid northern (main) forest, temperate forests and rainforests. And for now on, all of the primeval forest logging industries are being developed on a large scale to all the objectives of. Many tropical forests is already disappeared in the past 50 years been logged completely. There are more than 4.5 million hectares of tropical forests were engulfed the tropical forest area of 20 percent and millions of hectares of tropical forest in logging and mining of mineral resources farmlands and degradation in 90 century. And the global illegal logging and illegal trade continues wood products, especially in tropical forest of the developing countries and the government of the country such as Russia slacker enforcement. However the international market demand for cheap wood products farther worsened the situation.

Histroy record and Forcast

The mainstream scientific consensus that global warming is more and more obviously every day and changed our climate and environment. In the last 400-600 years of continued worldwide on global warming. Since the beginning of the 20th century, the surface of the earth's average temperature increased about 0.6 degrees Celsius (1f). Over the past 40 years, the temperature rise about 0.5 f (0.2-0.3 ° c) in the 20th century is more than any other time. In the 1990s. One of hottest year is 1998. Natural environment change of earth it is slowly warming up and alpine glaciers are gradually subsid. During last four years the arctic ice thickness has dropped about 40 percent. Global sea-level rise for about three times faster than the past 100 years than in previous 3000 years. Through research that shows plants and animals gradually chang their activity and behavior to respond climate change.While many of the world's scientists to predict the future is in 50-100 years, humans will fully into a warming world. The impact of human activities in the 21st century the greenhouse gases that future increase in global temperature of 100 increases rapidly. The global average surface temperature will increase by between 1.4 ° c - 5.8 degrees Celsius.

Consequence of Global Warming

Climate temperature increas cause melting glaciers and sea level will rise. The heat of the inertial effect of greenhouse gases will continue to affect our life and agriculture like agriculture, forestry, animal husbandry and fishery. The most terriffy problem is disease germs through such extreme weather and climate events (flood, drought and heatwaves)hile expanding the prevalence of the epidemic is causing harm to human health. The influence of climate makes more carbon dioxide and greenhouse gases into the atmosphere but cause damage. Who is unable to accurately estimate about the dangers of climate change is more serious. Even until 2004, scientists began to have ability to clarify the atmosphere and the mechanism of carbon dioxide. But truly understand all this to 2050. When the world's average temperature rise to 1 ° c it will casue sea-level rise, mountain glaciers retreat and snow area shrink. Global warming will cause the imbalance of rainfall precipitation increase in some areas and some other areas reducing precipitation. When the world's average temperature increase 3 degrees it will be too late to restrain. Esculent are gradually tight. The last 100 years, worldwide sea level 1-2 mm annually in the speed. Scientists estimate year 2050 sea level will be rise 30-50 centimeters and cause flooded low-lying coastal large land.Climate change such as drought disaster caused more than tens of billions of dollars in economic losses each year. In addition another global warming study result is Humans will face serious economic, social, and population statistics results of upcoming ice age because it will directly affect more than 80% of the population on earth, scientists concluded.

Conclusion

I believe that through the above evidences. That we need make a big choices. Believe. Global warming is not a joke or fraud. Of course,it not so obvious. and it is no threat to our daily life. Save the earth environmental need all of us to work together to save our home land.
