What is meant by climate change is the change in climate variables, particularly temperature and rainfall that occur gradually in the long period of time between 50 to 100 years (inter centenial). Besides, it should be understood that these changes are caused by human activity (anthropogenic), especially those related to fossil fuel use and transfer of land use. So the changes caused by natural factors, such as additional aerosols from volcanic eruptions, are not accounted for in terms of climate change. Thus the natural phenomena that give rise to extreme climatic conditions like cyclones that can occur within a year (inter-annual) and the El-Nino and La-Nina that can occur within ten years (inter-decadal) can not be classified into global climate change.
Human activity in question is an activity that has led to an increase in greenhouse gas concentrations in the atmosphere, especially in the form of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Gases was then determines an increase in air temperature, because it is like glass, which can forward the short-wave radiation which is not hot, but hold long-wave radiation that is hot. As a result the earth’s atmosphere got hotter at a rate equal to the rate of change of greenhouse gas concentrations.
Opinions of Experts
Scientists say climate change make the world a fertile ground for disease kerkembangnya because rising air temperatures can enhance the proliferation of infectious organisms. Increased wave attack viruses, bacteria, fungi and other parasites can disrupt ecosystems and even suspected could be the cause of deterioration in living things. » Read more: Understanding of Climate Change
