Global warming (global warming) is the phenomenon of global temperature increase due to the greenhouse effect (greenhouse effect) due to increased emissions of gases like carbon dioxide (CO2), methane (CH4), dinitrooksida (N2O) and CFC so that the solar energy trapped in the earth's atmosphere .
Various literature mentions that the increase in global temperature occurred in the range of 1.5? 40 Celsius by the end of the 21st century.
Global warming cause widespread and serious impacts to the bio-geophysical environment (such as melting polar ice caps, rising sea levels, expanding deserts, increasing rainfall and flooding, climate change, extinction of certain flora and fauna, migratory fauna and pest diseases, etc. .)
While the impact on the socio-economic activities of society. Among others: disruption of the function of coastal and beach cities. In addition, disruption of function of infrastructure and facilities such as roads, ports and airports. Also disruption of settlements, the reduction of agricultural productivity, to increased risk of cancer and disease. (various sources)

Sea water level rise
By considering the impact of global warming which has a national scale and long-term time dimension, then the existence RTRWN becomes very important. Broadly speaking RTRWN a predetermined aspect of legality through PP No.47/1997 as the elaboration of Article 20 of Law No.24/1992 on Spatial Planning policy guidance includes countries that show the spatial pattern and structure of national territory to be achieved in that time will come.
Patterns of spatial use of national territory includes: (a) the direction of policies and criteria for protected area management (including disaster-prone areas such as areas prone to tidal waves and floods), and (b) referral policies and criteria for the management of cultivated areas (forest production, agriculture, mining, tourism, housing, etc.). While the structure of national territory space use include: (a) the direction of development of national settlement systems and (b) the direction of development of national territory infrastructure systems (such as transportation networks, electricity, water resources, and raw water.

Impact of Sea Level Rise and Flooding on Environmental Bio-geophysical conditions and Socio-Economic Community
Sea level rise will generally result in impacts as follows: (a) increased frequency and intensity of flooding, (b) changes in ocean currents and the widespread destruction of mangroves, (c) expansion of sea water intrusion, (d) a threat to society's socioeconomic coast, and (e) decrease in land area or the loss of small islands.
The increased frequency and intensity of floods caused by the random occurrence of rainfall patterns and a short rainy season while the very high rainfall (extreme events). Another possibility is a result of backwater effects from coastal area to land. The frequency and intensity of flooding is predicted occurs 9 times greater in the next decade in which the 80% increase in flooding occurred in South and Southeast Asia (including Indonesia) with an area of the floodwaters reached 2 million square miles. Increasing the volume of water in coastal areas will provide the cumulative effect if the sea level rise and increased frequency and intensity of rainfall occurred in the same period.

Global Warming and the freezing of Europe
There is an interesting article from Science Daily that I have ever read that discusses the impact of global warming in Europe. This article was written based on the results of long-term numerical simulation of what would happen if the rate of greenhouse gases continue to grow in Earth's atmosphere. In the long term, Europe will increasingly cold turned out if global warming continues. The question is: â € œApa the cause of Europe will be more cool? Â €?
To address this problem, first you need to know about what is called the Great Ocean Conveyor Belt, which is a global ocean circulation in the circulation occurs transfer of heat energy absorbed by the seas of the tropics-which experienced a relatively constant solar radiation throughout the year - to middle-and high-latitude regions that receive different solar radiation energy during winter and summer (due to the earth's rotation axis which makes an angle of 23.5 degrees to the orbit).
Due to cold temperatures around the north pole (Greenland), there will be a freezing of sea water. Freezing of sea water will release the salt contained in sea water (and therefore, why the ice at the poles does not taste salty because the salt does not come frozen). The release of this salt will make the salinity of sea water becomes higher so that the density of sea water there also be higher too, as a result of sea water mass will decrease (known sebaga sinking or downwelling phenomenon or can be referred to as the ocean currents that move into the depths). Vacancy due to the decline of sea water masses that have a large density will be filled by the mass of the surrounding sea water, ie from lower latitudes or tropics. Sea water in the warm tropical climate makes the middle and high latitudes remained warm enough.
Global warming will cause polar ice caps melting. This causes the increase in the amount of water, resulting in dilution of sea water. As a result, the density of sea water to be reduced so that the process of sinking or downwelling would be weakened. The weakening of this process will reduce the amount of warm water coming from the tropics.

Global warming health impairment.
Skin cancer.
Greenhouse gases are accumulating in Earth's atmosphere contributes to global warming and the subsequent increase in damage the ozone layer. If under normal circumstances, the earth's atmosphere can hold 95 percent of ultraviolet radiation ofthe sun, and only five percent of the radiation that penetrates the earth, but now that layer is not able to sustain, especially around the south pole.
This situation can lead to people in the area is exposed to skin cancer.However, it does not mean that we are free here to be exposed in the sun without anyprotection. We can do: Make sure you apply the cream or lotion sunscreen 20 minutes before you leave home. Preferably with SPF 15 or lebih.Sebaik possible, apply thecream as well as in both ears and your feet. If you feel you would be in the sun for along period of time, choose a lotion with SPF 30 or higher. It effectively resist theharmful rays of the sun on your skin.

Global Warming & Greenhouse Gas: Developed Countries Must Act
For the period 1997 to 2008, emissions of carbon dioxide in the world due to the useof fossil fuels increased by 31 percent. Citizens of the world wants to 'speed' of global warming can be reduced.
It means that the amount of carbon dioxide should be reduced, because otherwise wewill face heavy pressure over again. Traveled life more difficult when the disasteroccurred and during post-disaster period. Billions and billions of dollars of lossessuffered due to the destruction of property and lives.
Many agricultural and fishery programs will be affected because of the dramaticseasonal changes in addition to threatening many species. All the world's oceansincreased by 1.5 inches. Global temperature will increase, thus lead to theincompatibility of the world community. Hundreds of blocks of ice from both poles of the earth to melt and affect global weather.
See how the phenomenon of the summer and more severe forest fires around the world, the United States (U.S.) to the west to Australia. Temperature last 12 years the world was found to be 0.4 degrees Celsius warmer than 12 years before 1997.
This frightening scenario of environmental citizenship. Ten years ago, meteorologicalscientists think climate change will not happen as bad as happens now, if no drastic action is taken, certainly more bad news related to the environment will follow later.

EARTH WARMING DUE TO NATURAL DISASTERS
Amsterdam # Amsterdam, Netherlands - The number of natural disasters in 2007 rosespectacularly, according to the International Red Cross. When compared with last year,the figure increased 20 percent recorded until October, the number of natural disastersreached more than 400. Each year 270 million people become victims of natural disasters in the world. In previous decades this figure was 240 million. Almost half ofthese natural disasters related to weather, world disasters report issued by the International Red Cross. Climate change summit currently taking place in Bali havereached an agreement about the reduction of CO2 greenhouse gases, which affectweather changes.
