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.
Cause of global warming
Everyone now has recognition to “Global warming”, and it acts because the concern for the environment and it begins to work in the shape that sticks to our life.
Then, what do you cause as for “Global warming”?
Also because “Global warming” paid attention to all over the world is a content exactly related to the human race’s continuing, various discussions are done.
The theory of the main style is the one as the cause of “Global warming” by having exhausted “Heat-trapping gas” along with the industrial activity that has been done so that we human races may develop.
The heat-trapping gas that the human race generated is assumed according to AR4 (the fourth evaluation report) issued by “Intergovernmental Panel on Climate Change” and the probability of cause of “Global warming” is assumed to exceed 90%.
AR4 (the fourth evaluation report) is this consolidating an academic finding of now most, and the report acknowledged worldwide.
Therefore, when the discussion of relating to the cause of “Global warming” is executed, this report is a main axis.
However, meteorological observation data here and there and a huge calculation are needed all over the world for the root cause analysis on Global warming.
The analysis is done by various climate models by the use of data that observes the temperature directly and the temperature presumption data, etc. for the past tens of thousands of years for the calculation.
It is assumed that the influences such as carbon dioxides and methanes that are still a kinds of the heat-trapping gas as the cause of “Global warming” are large as a result of the analysis.
It is presumed by another that there are various causes like human race’s land development and the use of the aerosol, etc.
Mechanism of global warming
There is various kinds of “Gas” assumed that it is a cause of “Global warming”.
It tries to the gas with the especially largest influence of “Carbon dioxide” on global warming.
The use of the fossil fuel keeps increasing since the Industrial Revolution, and the amount of carbon dioxide included in the atmosphere as a result increases, too.
The normal temperature announces in 2100 after about 90 years that 1.8℃?4.0℃ will rise when Intergovernmental Panel on Climate Change (IPCC) advances as it is by global warming.
Even when the heat-trapping gas that influences global warming is the least, 4.0℃ of a lot of cases that are is 1.8℃ oppositely.
- Global warming mechanism
Is everyone heard, “Global warming”, and can it explain the mechanism though present when a variety of easing plans such as discretion, power savings, and recycling garbage are done?
The normal temperature in the entire earth is about 14℃ now.
If neither carbon dioxide, the methane nor the heat-trapping gas such as steam are completely contained in the atmosphere, the normal temperature might become degrees how many though this is an important numerical value where the human race exists.
The numerical value is assumed to be subtract about 19℃.
The light of the sun that gives us warm sunlight passes by in the atmosphere in the earth and warms ground.
As a result, the heat-trapping gas absorbs the heat, it heats the air, and it exists though heat is radiated from surface of the earth.
I think that you understood saying that the heat-trapping gas is a gas necessary for the human race.
However, it came to exhaust heat-trapping gases such as carbon dioxide, the methane, and fluorocarbon in large quantities by activating the industrial activity in recent years.
As for the heat-trapping gas on an atmospheric inside, the densities rise more than natural values, and the absorbed amount of heat has increased.
It is “Global warming ..connection… ” to the rise of the result and the temperature.
Density of carbon dioxide
An increase of heat-trapping gas that is key factor of global warming.
It seem to be still to our regret in the increasing tendency though a variety of easing plans are promoted all over the world.
The kind is various even if it is said to one item, “Heat-trapping gas”.
Carbon dioxide is 60% when the influence level to global warming is examined according to the kind of the heat-trapping gas, the methane is 20%, and the nitrous oxide is assumed that 6%, the ozone-destroying chlorofluorocarbon, and halon are 14%.
It can be said that the carbon dioxide exhausted as a result by the combustion of fossil fuels such as indispensable oil and coal to industrial development will have the maximum influence on global warming.
It increases by 379ppm and as much as 35% in 2005 in recent years though the density of carbon dioxide is 280ppm in 1750 before the Industrial Revolution.
It has been reported in various observations and the pasts the highest increase rate from the result of the forecast in 20,000 years in the past.
Is it twice in about 2100 when global warming advances as it is compared with 1750?It is forecast that it increases up to three times.
It is reported that the country where the amount in which carbon dioxide has been exhausted is the largest has exhausted five billion tons or more a year in the United States. This numerical value reduces around and the United States carbon-dioxide emissions to 24.4% of all parts of the world and a big effect will be achieved.
It is still a country where ..the fourth place in the world.. amount of the exhaust is large though carbon-dioxide emissions of Japan become about the United States 1/4 or less.
As for the United States, a lot of amounts of the exhaust per person are reported to about twice Japan, about 9 times China, and about 18 times India though it sees from the cut of the population ratio.
Breakdown of heat-trapping gas
An increase of heat-trapping gas forecast direct cause of “Global warming” phenomenon.
It continues with the United States, Australia, Canada, Russia, Germany, Britain, and Japan in order in the country where the amount of the exhaust a person of carbon dioxide (CO2) is large though an exhaust amount increase of carbon dioxide especially occupies the many.
The majority of the 3/4 or more are reported the combustion of the fossil fuels such as coal and oil as a translation while being increase the density of carbon dioxide in the atmosphere in the past 20 years.
“Advanced country” such as the United States, Russia, and Japan where industry and industry are advanced as understood even if the amount of the exhaust a person is seen occupies the large percentage, and it is understood to bear a heavy responsibility to “Global warming” easing.
The amount of the exhaust a person in the advanced country greatly exceeds developing countries’ emissions.
The amount of the exhaust a person under the present situation is done proportion to industry and economic development and is increasing rapidly in the developing country however though tends ..few…
In any country, it is necessary to form the system that controls economic development and the exhaust of the heat-trapping gas by doing “Coexist” all over the world.
As for the heat-trapping gas, the methane, the nitrous oxide, and fluorocarbon, etc. are enumerated besides carbon dioxide.
- Methane
It is reported that the combustion of fossil fuels and the land development of reclamation etc. are causes more than the half of the cause of the exhaust of the methane.
The atmospheric level of the methane is in 150% increasing tendency since 1750, too and it is progressing now.
- Fluorocarbon
It has the character to rip up the ozone though all fluorocarbon is good ..not doing.. and it is thought that it knows.
