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
