But, in Comedy of Character, the Individual is self-determined; his situation, in its essential points, is the consequence of his own action  of his own folly or weakness; he is not plunged into it from without, by fate or by accident. In this sphere the Individual will find a realm of freedom.
CO2 - the major cause of global warming. Global warming is caused by the emission of greenhouse gases . 72% of the totally emitted greenhouse gases is carbon dioxide (CO2), 18% Methane and 9% Nitrous oxide (NOx). Carbon dioxide emissions therefore are the most important cause of global warming. CO2 is inevitably created by burning fuels like e.g. oil, natural gas, diesel, organic-diesel, petrol, organic-petrol, ethanol.
The reason why carbon dioxide is considered as the major cause of climate change when other greenhouse gases have strong energy of holding the heat and remains inside the atmosphere for quite long period of time is because the increasing amount of emitted carbon dioxide is awfully large.
