Global Warming Article

           A phenomenon which discusses the process of increasing the average temperature of the atmosphere, ocean, and land earth is defined as global warming. Earth’s climate has change since  many human activities that intentionally and un intentionally would damage the environment. Based on Integovermental Panel on Climate Change (IPCC) (2013), the interval between 1880 and 2012 saw an increase in global average surface temperature of approximately 0,9 ^○C. furthermore, IPCC (2013) argues that most of the warming observed over the second half of the 20^th century could be attributed to human activities. The phenomenon is called global warming and it occurs due to several reasons.

          The first cause of global warming is the greenhouse effect. Earth’s average surface temperature occurs because of the balance of various forms of solar  radiation and radiation form the earth. Aren’t et al., (2014) shows that scientists are finding ways to eliminate greenhouse gases, and meanwhile, they suggest measure to reduce greenhouse gas emissions. In addition, Falkowski (2012) shows that among these current measures, using phosynthetic organism such as plants and algae to take up carbon dioxide is a well – accepted one. Moreover, boyd et al., (2000) arguws that an early experiment involving adding iron to the ocean confirmed that algae could absorb CO2 and thus eliminate the effect of global warming.

          The second cause of global warming is radiative forcing. Radiative forcing is a parameter that can be used in analyzing the symtoms of climate change. IPCC (2014), shows that radiative forcing is a measure of the influence a given climate factor has on the amount of downward – directed radiant energy impinging upon earth’s surface. In addition, Myhre et al., (2001,2013a);Shindell et al., (2013); Lee et al., (2013) argues that direct radiative forcing (DRF) of aerosols, which involves the scattering or adsorption of solar radiation by aerosols, has inceased since the preindustrial era. Moreover, Myhre et al., (2013a) argues that estimated a global mean aerosol direct forcing of -0,35 Wm^-2 in 2011 relative to 1750, with large uncertainties of -0,85 to +0,15 Wm^-2.

          The last cause of global warming is the influences of human activity in climate. Human activities often make the environment becomes unstable because of the activities that damage the environtment vegetation. Cao et al., (2006);Zhuo et al., (2007);Wang et al., (2009); Li et al., (2011);Huang et al., (2012) shows that some researchers also noted that human activities, especially some ecological construction project, greatly influence vegetation change is caused by human activities both impact vegetation; however, it is unknown how much vegetation change is caused by climate variations and how much is caused by human activities. Moreover, Moraes et al., (1998) shows that the impact of human activity has been suggested but not investigated in detail.

So,human being need to be aware of his action and start to fix the earth. The fundamental way to be applied in public life in general, such as changing patterns of energy use. Saving use for fossil fuels also necessary to reduce the pollution resulting from fuel combination. Human must maintain the integrity of vegetation in a way not to harm the environment. In essence, it is a surrogate nature our children and grand children later, and it is fitting we keep as much as possible so as not undermined by irresponsible.
