Greenhouse gases (CO, CO2, CFCs, O3, NOx) accused as the cause of global warming. However, I wish the earth had no greenhouse gas2 then this earth will have celesius temperature of 33 degrees below 0. gas2 greenhouse concentrations have increased in recent years. Some say because man, some say due to geological activity, some say because of the carbon cycle in sea obstructed. CO2 gas come out of nowhere, a clear increase in the concentration of greenhouse gases is causing the amount of solar energy reflected back to earth to be larger or in other words there is a relationship between elevated concentrations of atmospheric greenhouse gases with global warming. CO2 accounted for 50% of global warming, whereas CFCs gases, CH4, O3, and NOx each accounted for approximately 20%, 15%, 8% and 7% for global warming.

Federal environmental study group Climate Change Science Program on 2 May 2006 issued a statement that the human mempegaruhi global climate change. One result of global warming it is climate change. Apparently one man who was accused of causing increased CO2 content in the earth. According to proponents of this theory, the CO2 in the earth has increased dramatically as a result of human activity and human activity also causes inhibition of re-absorption of CO2 by plants. Humans play a role in promoting the CO2 in the atmosphere. Plants in this paper I reply to the forest konotasikan who is the main absorber of CO2 in the atmosphere that are directly related to human activity. Several other studies have claimed that turns humans (antrhopogenic) only donate 5% of CO2 production in the world. » Read more: Causes of Global Warming
