1.  This presentation is included for reflection by
practitioners in planning for learning and
teaching. It is intended for exemplification
purposes only. It may be appropriate for some
teachers/lecturers to adapt these materials for
use within their own context.

2. Causes

3.  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.
 Try the card sort activity, which your teacher
will explain.

4.  Volcanic dust
 Ice cap melting
 Sunspot activity
 Changing ocean circulation (El Nino/La Nina)
 Permafrost melting

5.  Deforestation
 Burning fossil fuels
 Aircraft contrails
 Cattle farming (methane)
 Nitrous oxides from power stations
 CFCs from refrigerators and aerosols

6.  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.

7.  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.

8.  Weather becoming less predictable.
 More flooding, droughts, tropical storms and
heat waves.

9.  Alternative forms of energy
 Solar
 Tidal
 Wind (on-shore and off-shore)
 Hydroelectric

10.  Electrical cars.
 Reduce deforestation and increase
afforestation.
 Control population.
 Reduce energy consumption at school and at
home.
 World summits.
