Al Gore's global warming movie, "An Inconvenient Truth," aims to call attention to the dangers society faces from climate change, and suggests urgent actions that need to be taken immediately. With motive to educate and make aware a common man about “Global Warming”, former US vice president Al Gore made more than 1000+ presentations through-out the world. As a documentary, this film is a typical in that it has no interviews with scientists on the subject Al Gore explained how the atmosphere works; sun ray comes from the sun everyday then some of the rays stay inside the earth with the help of ozone layer to keep it warm. The crazy increase of carbon dioxide ratio has made the layer thicker so more rays are trapped more than we normally need. As a result, a lot of temperature changing can be seen around the world such as heat wave. Another problem the global warming is causing is that the ice is melting which is a very serious danger. The level of the sea, constructions and the weather itself all can be affected if the ice or permafrost starts to melt down because of the increasing of heat. At the end of his discussion, Al Gore confirmed that most of the scientists around the world agree that we are the main reason for the global warming. With respect to the science, the keystone to the documentary's argument is the lengthy historical record from ice core studies correlating atmospheric CO2 and global temperature. Al Gore then looks at CO2 and temperature in the past 30-odd years, and by extrapolating a nearly vertical rise in CO2 into the future, implies an impending catastrophic temperature rise. Now Al Gore does make a reference to the relationship of CO2 and temperature as "complicated" - but what is complicated is the cause and effect relationship between the two, which he glosses over. Moreover, the relationship between CO2 and temperature is not linear, as Al Gore implies, but...
