0. Which gas is responsible for 'Global Warming'?
- Option : C
- Explanation : Global warming is caused by the emission of greenhouse gases. 72% of the totally emitted greenhouse gases are
• 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 and ethanol.
