  1. - Change in climate Why it changes - The sun emits sunrays - The Earth absorbs the energy - Infrared rays are radiated from the Earth - Greenhouse gases thickens the atmosphere Climate change - Heat (infrared rays) is trapped - 'Climate change' or 'global warming'?

  2. Natural activities - Animals and plants decomposing - Volcanic activity - Vaporised water Human activities - Greenhouse gas emissions Causes - Interventions with natural activities

  3. In cold environments - More habitable land - More arable land In high mountain landscapes - More drinkable water Postive consequenses

  4. In general - Imbalance in animal and plant population - Land erosion Low land environments - Higher water level Negative consequenses

  5. Confronting the primary causes - Humans - Greenhouse gasses Confronting the secondary causes - Human interventions with natural activities - Activities involving the use of fossil fuels or biofuels Preventing climate change - Activities involving plastic - Volcanic activity - Animals and plants decomposing - Water vaporisation
