Global Warming
☆ Global Warming?
The global warming, by greenhouse gas that occurs with human activities increases the concentration of greenhouse gases in the atmosphere, it says that the temperature near the ground rises. There are different types of methane, nitrous oxide, and CFCs to the greenhouse gas effect, but the most common is carbon dioxide. Atmospheric concentration of carbon dioxide in the pre-industrial was about 280ppm. However, had risen to 370ppm in after the Industrial Revolution. It is anticipated to be 540 ~ 970ppm by the end of the 21st century If leave this. Temperature of the earth's surface has 0.3 ~ 0.6 ℃ rise in the 100 years. There is no example in which the temperature has risen so much in 100 years even when viewed
from the history of the Earth. I believe the increase in greenhouse gases is causing global warming.
☆ Effects of Global Warming?
Intergovernmental Panel on Climate Change, predicted the average temperature of the Earth's surface to 1.4 ~ 5.8 ℃ rise to the end of the 21st century. There is a significant impact on the environment such as global. Because the trees can not be adapted to the speed of temperature rise in the short period of 100 years, receive a big blow. Impact on the animals who live there is also large. In addition, it is said that global warming proceeds, due to expansion of seawater and melting of glaciers, sea level will rise. Intergovernmental Panel are expected to 9-88 cm rise in the end of the 21st century. This is a serious problem for people living in low-lying and island nationIn addition to this, the potential impact has been pointed out several dry granary of natural disasters due to changes in precipitation patterns, the expansion of the endemic areas of animal infection.
☆ The Kyoto Protocol?
To prevent global warming, it is necessary to reduce the concentration of greenhouse gases in the atmosphere, the second report in the atmosphere of the Intergovernmental Panel in 1995, to stabilize carbon dioxide in the atmosphere , I have pointed out that must be reduced 50-70%.From the developed countries towards the realization of this task, were greenhouse gas emissions that many of responsibility, was targeted greenhouse gas emissions by developed countries to reduce is the Kyoto Protocol. In the Kyoto Protocol, it was decided to reduce by at least 5% compared to 1990 to 2008 to 2012 emissions of six greenhouse gases in developed countries as a whole. The difference is provided in accordance with the circumstances of each country is desired, that Japan is required the 6% reduction.
