Factor of global warming
The temperature of the atmosphere and the ocean on the earth keeps rising in recent years when environmental problems become aggravated, rise and abnormal weather of the sea level by “Global warming” are observed, and the big menace for the human race and the ecosystem.
“Global warming” is divided into a problem of an original, natural origin and a human factor on the earth.
It is said that the theory called the heat-trapping gas generated by human race’s industrial activity etc. is a key factor is the most powerful as a factor of “Global warming” in the latter half on the 20th century of recent years.
In “The fourth evaluation report” that an intergovernmental panel of the United Nations issued in 2007, establishment whose heat-trapping gas that the human race generated is a cause of “Global warming” is reported to be 90% or more.
The normal temperature is reported to be the maximum rise of the transition of 6.4℃ and the surface of the sea by 38.5cm on the average according to a scientific finding of “The fourth evaluation report” in 2100 on the future of the future.
It is said that the influence of in that or carbon dioxide and the methane is large though “Global warming” is assumed that the discharge of the heat-trapping gas that the human race generated is a factor.
Moreover, the generation of the aerosol and the soot contained in the decrease and the vehicle exhaust emission etc. of the albedo by doing an artificial land use is one of the causes.
The influences such as Earth’s climate, the weather situation, and seawater are exerted on the heat-trapping gas such as the carbon dioxide generated by one degree by the surprise for about 100 years.
Only only about several % of the amount of the change of the calorie etc. that the sun radiates as a natural phenomenon exists compared with the factor of the human race who describes in the above-mentioned, and “Global warming” to present is assumed that it is sure to happen only by the natural phenomenon that surrounds the earth and the earth.
