Methane, the hydrocarbon is responsible for global warming. CFCs cause a hole in the ozone layer to be formed, while sulphur dioxide causes acid rain. Carbon dioxide forms a blanket layer to be formed around the earth, thereby preventing heat from being lost, resulting in rising global temperatures.
Increased greenhouse gas concentrations in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming, causes global warming.
- When we burn fossil fuels like coal, oil and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere.
- When vegetation is removed or burnt, the stored carbon is released back into the atmosphere as CO2, contributing to global warming.
- The amount of methane produced is a big contributor to global warming.
- Some fertilisers that farmers use also release nitrous oxide, which is another greenhouse gas.
