What Is All The Fuss About?
This is the main controversy over global warming: “Are Humans causing it?” Well, instead of having a big debate over it, lets look at what emits the most CO2. The movie The Great Global Warming Swindle claims that humans actually emit very little of the CO2 on earth today. They said that most of the CO2 is coming from Mother Nature.
Natural CO2 sources can include large concentrations from volcanic activity vegetation and other natural resources, but main no human contributors are the oceans. They contribute a lot to the emissions of CO2, but the question is, “How much CO2 does nature emit compared to how much humans are emitting today?”
Other than natural causes, humans are said to be having a large effect on CO2 and that is causing the temperature to rise. Some causes of human emitted CO2 are from chemical operations, transportation, deforestation and the manufacture of other products. So humans may have many causes that emit CO2, but it depends on how much of a factor they are in the big picture.
The Great Global Warming Swindle and other resources said, that humans accounted for a very small amount of CO2 emissions. To be exact, Oceans alone contain 37,400 GT (aka: billion tons) of carbon dioxide, and humans only contribute 6GT of carbon dioxide. So when you compare those two, oceans contribute so much more than humans do and oceans have been here all along. So how could humans possibly be affecting the earth when they are only contributing so little?
On top of the fact that humans contribute so little to the CO2 emissions, CO2 is such a small component of the atmosphere itself. CO2 is only .03% of the earth’s atmosphere so even if humans emitted a lot of CO2 it would not contribute to the atmosphere very much at all. So when you add together all of the factors together, you just have to ask yourself “How could humans be the cause of global warming?”
