Sources of production of greenhouse gases:
- individual: modern comfort = cars, computers, fridges, washing-machines and TV - anything that uses electricity
- industries: production of electricity with nuclear power plants, fossil fuels = gas, coal, petrol + deforestation, intensive farming, transport, factories, industrialised countries and developping countries.
evolution of temperatures: in the last 100 years, the Earth's temperature has increased

4 initiatives to lower gas emissions:
- Governments have encouraged renewable energy from wind and water
