EFFECTS OF GLOBAL WARMING

WEATHER

-Winter and summer temperatures will increase and hence the weather will be warmer
-in other parts of the world, the effects will be different since some places will become drier and others will be wetter
-many storms, floods and droughts may occur but we do not know which areas of the world will be affected
-these weather changes will affect the kind of crop that can be grown
plants, animals and even people may find it difficult to survive in different conditions

SEA LEVELS

-Higher temperatures will make waters of seas and oceans expand
-ice melting in Antarctic and Greenland will flow into the sea
-sea levels may rise perhaps as much as 20 to 40 cm by the beginning of the next century
-higher sea levels will threaten low lying costal areas of the world, millions of people and areas of land will be at danger of flooding
-many people will have to leave their homes & large areas of farmland will be ruined due to floods

FARMING

-changes in weather will affect types of crop grown in different parts of the world
-Wheat & rice grow better in higher temperatures, but other plants such as maize & sugarcane do not
-changes in amount of rainfall will also affect how many plants grow
-effect of a change in the weather on plant growth may lead to some countries not having enough food
-brazil, parts of Africa, south-east asia & china will be affected & many people could suffer from hunger

WATER

-there is a big demand for water and in many regions such as: sahara in Africa, there is not enough water for people
-changes in weather bring more rain in some countries but others will have less rain
in Britain , south-east will be at risk from drought

PLANTS & ANIMALS

-weather and temperature changes, homes of plants and animals will be affected all over the world
-polar bears, seals will find new land for hunting and living if ice in the artic melts
-many animals and plants may not be able to cope with such changes and could die
-this could lead to less of some animal and plant species in certain areas of the world or everywhere on earth

PEOPLE

-climate changes will affect everyone but some populations will be at greater risk
-countries whose costal regions have a large population such as Egypt and china may see whole populations move inland to avoid flood risk areas
-effects on people will depend on how well we can adapt to changes & how much we can do to reduce climate change in the world
