Causes of Global Warming
- Industry
- MEDCs
- More CO2 is produced than in LEDCs
- Fossil fuels
- Industrial revolution increased use of fossil fuels.
- When burnt they release CO2 and SO2.
- LEDCs
- Not much CO2 released as their industries aren't as developed.
- As industries develop CO2 levels will increase.
- Transport
- Airplanes
- Airplanes produce high levels of CO2
- Petrol and diseal
- Combust to release CO2
- Agriculture
- Cattle
- Cattle farming releases methane.
- Greenhouse gas
- Deforestation
- Disrupts photosynthesis
- Trees take in CO2.
- Release oxygen
- Releases large amounts of CO2
into the atmosphere.
- Combustion
- Releases CO2
- The Greenhouse effect
- Solar radiation reaches the earth as
short wave radiation (sunlight).
- The Earth's surface absorbs and re-radiates the solar
energy as long wave radiation (heat).
- Greenhouse gases
- Water vapour
- carbon dioxide
- Nitrous oxide
- Methane
- Absorb the long wave
radiation and heat the lower
layer of the atmosphere.
- CFCs
- Fridges and aerosols
- Many occur
naturally.
