4.13 Greenhouse gases
Notes
Human activity (fossil fuels) ---> Increased (CO2, NO2) <-- GHG & SO2
- Industrial
- Vehicles
- Domestic (homes)
- Farming = cows digest crops, emit methane gas to GHE (9% of gases)
-Water vapour = clouds are main contributors
- Refrigeration (CFCs) = absorption of UV light, catalysing breakdown of Ozone layer
