Global Warming

Global warming is the increase in the average temperature of the Earth's surface because of the greenhouse gases effects, such as carbon dioxide or methane, increase in the air.

The atmosphere such as nitrogen or oxygen surrounds on the surface of the earth. The light of the sun arrives on the earth is finally discharged the reflection on the surface of the earth and radiant heat in space, but change of a sudden temperature is moderated because there is the atmosphere. The atmospheric carbon dioxide is 0.03% and it is few, but the carbon dioxide absorbs heat emitted by the surface of the earth and emit it again in the surface of the earth, the atmosphere can keep on average temperature of the earth around 15 degrees centigrade. Such a gas is called greenhouse gases.

Humans used coal or oil in large quantities with industrial development from the latter half of the 18th century. The density of carbon dioxide became more than double current in the end in the 21st century if humans continue carrying out similar activity. As a result, it is predicted that the average temperature of the earth is rised from now. It is said, when discharge of the greenhouse gases are the least, the average temperature is rised of 1.8 degrees. The most, the average temperature rises an average of 4.0 degrees in 2100.

In addition, methane and chlorofluorocarbon are greenhouse gases, too. Artificial chemical substances such as chlorofluorocarbon are stronger in the greenhouse effect than carbon dioxide, the influence of it is worried about with a little quantity. The global warming is caused by carbon dioxide or chlorofluorocarbon. It is approximately certain that factitious activity is a cause.

When warming advances, in Japan, we cannot harvest delicious rice and the concern of insects causing damage to crops increases. The Influence is reflected in quantity of a catch of fish. The number of Mackerel and mackerel pike continue increasing. On the other hand, abalone, a turban shell and dthe sockeyes will decrease. In addition, the danger of dengue fever prevalent in the southern part of Japan is increased, and it is thought that harmful insects such as cockroaches are seen in Hokkaido and Tohoku. Heat island effect is accelerated in the urban region, and the number of sandy beaches of the coast decrease, and the number of danger zones caused by high tide and the tsunami increase remarkably.

Seeing from a global viewpoint, the surface of the sea rises, and many islands sink into the sea. The big damage is given in particular in the Marshall Islands and Bangladesh, with much low land. In addition, the warming causes abnormal weather, and the water cycle is affected in each place on the earth. As a result, the area undergoing short of water and dry comes out. On the other hand, areas where flood occur frequently. Such change in climate have a big influence on the crop of global farm products, the quotation of the international markets change greatly. Am anxious about Influence on Japan where the import of foods dependence ratio is high.
As for the emission of greenhouse gases in Japan, most of the emission are caused by industrial activity. The carbon dioxide emission is influenced easily by energy demanded. So energy save and energy convert in industry are gone forwarded, and more positive measures are expected.

In conclusion, it is necessary to change our lifestyle to prevent warming. It is important that to use things carefully without buying things unnecessary as much as possible, and to keep reuse and recycling in mind. In addition, Had better saved electricity and not use a car, use a bicycle and public institutions.
