Climate Change Revision
We are learning to… Define the causes of climate change Give example of the effects of climate change Give examples of methods to manage the effects of climate change
I can… Distinguish between human and physical causes of climate change Answer questions on the effects of climate change Give examples of methods used to manage these effects
Climate Change Causes
Causes of climate change It is very important in geography that we can categorise causes of climate change into two subgroups. We need to group them into: 1. physical causes 2. human causes. Sort out the cards into Physical and Human causes – Have them checked!!
Physical causes Volcanic dust Ice cap melting Sunspot activity Changing ocean circulation (El Nino/La Nina) Permafrost melting
Human causes Deforestation Burning fossil fuels Aircraft contrails Cattle farming (methane) Nitrous oxides from power stations CFCs from refrigerators and aerosols
Effects can be local or global Sea level rise Melting ice caps and glaciers. Flooding of low-lying areas such as UK fenlands, Shetland Islands, Bangladesh, Maldives and Japan. Higher water temperatures mean that water expands further, compounding the problem.
Effects Polar bear habitats in the northern hemisphere are shrinking. Tourism problems for snow areas. The Mediterranean may become too hot for some tourists. Crop failures. Extinction of species. Bleaching of coral reefs. Tropical diseases such as malaria spreading.
Effects Weather becoming less predictable. More flooding, droughts, tropical storms and heat waves.
Management of climate change Alternative forms of energy Solar Tidal Wind (on-shore and off-shore) Hydroelectric
Management Electrical cars. Reduce deforestation and increase afforestation. Control population. Reduce energy consumption at school and at home. World summits.
