Presentation transcript:

Climate change - 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 - Heat (infrared rays) is trapped - 'Climate change' or 'global warming'?

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

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

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

Preventing climate change 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 - Activities involving plastic - Volcanic activity - Animals and plants decomposing - Water vaporisation
