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
