Climate change can be explained as a modification of climate factors, particularly temperature and rainfall that happen steadily over a long period of time between 50 to a century. Apart from it should be understood that the changes brought on by human exercise (anthropogenic), especially those associated with fossil fuel consumption and overland.

Therefore the modifications brought on by all-natural factors, like additional aerosols from volcanic eruptions, usually are not accounted for when it comes to climate change. Therefore the natural phenomena that lead to extreme climatic conditions such as cyclones can happen each year (inter-annual) and El-Nino and La Nina, which could take place in 10 years (inter-decade) are unable to be classified into worldwide climate change.

Human being activity in question is definitely the activities that have resulted in a rise in atmospheric concentrations, particularly by means of co2 (CO2), methane (CH4) and nitrous oxide (N2O). The fumes then decide the heat increase, because it is like a window, which can toward shortinflux radiation which is not hot but keeps lengthyinflux radiation which is heat. Consequently, the earth’s atmosphere gets hotter.

The impact of climate change:

Gardening industry is going to be affected through the reduction of food productivity brought on by the increase in cereal sterility, a decrease in the region can be irrigated and reduce the effectiveness of nutritional absorption and spread of unwanted pests and diseases.

In some places within the developed (high latitudes) increase in CO2 concentration increases productivity due to increased assimilation, however in the tropics that many developing nations, an increase of assimilation had not been significant compared with respiration which is also increased. On the entire, if adaptation will not be done, the world will experience a decline in meals production to 7%.

Nevertheless, with ongoing degrees of adaptation, which means higher costs, meals creation can be stabilized. In other words, stabilization of meals production on climate change will cost extremely high, for example by enhancing irrigation facilities, the supply of inputs (seeds, fertilizers, insecticides/pesticides) additional.

Warmer temperatures may cause a change in plant life varieties and ecosystems. Mountain locations will lose numerous species of original vegetation and replaced by lowland plant life varieties. Together with that, the condition of drinking water sources from your mountains may also be susceptible to disturbance.

Moreover, the steadiness of property in mountainous locations is also interrupted and difficult to keep your initial plant life. This effect is not so apparent within the reduced latitude areas or reduced height area. If increasingly more woodland fires are common in Indonesia, it was hard to link the occurrence with climate change, because of most (if not completely) incidents of forest fires caused by human being activities related to land clearing.

That occurred along with the El-Nino events for this reason trend offers dried out climate conditions that help the appearance of fire. However, as explained previously mentioned El-Nino is a trend of nature which related to extreme climate occasions in environment variability, not climate change within the which means as explained previously mentioned. Growing of population makes pressure on drinking water supply, especially in urban locations.

At this time there are numerous city citizens that have difficulty obtaining water that is clean, especially those people who are lowincome and reducededucated or unskilled. The impact of climate change which in turn causes changes in heat and rainfall will have an effect on the accessibility to drinking water from the surface area runoff, groundwater as well as other reservoir designs. Around 2080 there will be 2 – 3.5 billion dollars people will encounter drinking water shortages.
