Such climate changes never attained any fearful proportions and hence the there were no serious treats for the sustainment of life on earth till the last few centuries. An Inconvenient Truth was a documentary film directed by Davis Guggenheim, in 2006, in which former United States Vice President Al Gore tried to educate the citizens about the necessity of preventing global warming. He has mentioned that it is crucial to change the attitude and behavior of the public to counter the climate change problems. In his opinion, climate change problems should be taken as a moral one rather than a political one (An Inconvenient Truth, 2006)
But over the last few decades, the balancing between the energy liberated from the sun and the energy reached on earth was destroyed seriously because of many known and unknown reasons and as a result extreme weather conditions started to appear on earth’s atmosphere/surface. Even though the exact reasons for the climate changes on earth is still unknown or controversial, many people believe that the destructions forests, injudicious industrialization, long- and short-term variations in solar intensity, deviations in the Earths orbit, mountain-building and continental drift, and changes in greenhouse gas concentrations etc are the major reasons for the drastic climate changes on earth’s surface. In short, “climate change is already happening and represents one of the greatest environmental, social and economic threats facing the planet” (Climate change, 2010).
Climate changes can affect the human life on earth in many ways. In this paper the climate change impacts on local food production in Nah Trang, Vietnam is described. Nah Trang sits within a coastal province in south central Vietnam with an area of 3352.27 km2, coastline of 105km and annual rainfall of 600mm. Shrimp farming is one of the major revenue source for the people in Nah Trang. The lack of
