The causes of Global Warming


There are many causes of global warming. First of all, carbon dioxide which is coming
from industrial plants and it happens by the burning of fossil fuels for the purpose of electricity generation. The second cause is carbon dioxide from cars because of the burning of gasoline in internal-combustion engines and also from trucks and airplanes. In addition, it happens from building structures. The second most important cause is methane, which is more than 20 times as effective as CO2 at trapping heat in the atmosphere. Also there is a gas which the scientists call “laughing gas” and it’s sometimes used as an anesthetic. After carbon emissions caused by humans, deforestation is the second principle cause of atmospheric carbon dioxide The atmosphere contains about 750 billion tons of carbon, while 800 billion tons are dissolved in the surface layers of the world's oceans. Furthermore, scientists have found that most drivers waste millions of gallons of gas while just sitting in traffic.
