The Effects of Climate Change

The Effects of Climate Change

Agriculture

• Crop yields are expected to decrease for all major world crops.
• Agricultural land on the edge of deserts becomes unusable, through the process of desertification.
• Crops could be wiped out in low-lying areas that suffer from flooding. With less crops available on the world market, prices are likely to increase.
• The growing season in some areas will increase. This is a benefit to places such as the UK as more crops could be grown.

Sea Level Changes

• Coastal land is at risk, especially land on deltas.
• Sea defences are under more stress.
• Low-lying land is threatened so the lives of 80 million people across the globe are threatened.

Water and Ice

• More mass movement can occur as glaciers melt.
• Communities that use the melt water from glaciers may see this supply decrease. This is especially the case in Asia.
• Economies that rely on skiing as a form of income may suffer as the skiing season is reduced or disappears through lack of snow.
• Locations suffering from water stress will increase in number.
• Less fresh water will be available in coastal areas as it will mix with sea water, which is salty.

Population

• 
• People will migrate from areas suffering drought. Any that remain will be in danger of dying from starvation and lack of water.
• 17 million people in Bangladesh alone will be threatened by flooding.
• As the world population increases, more people will be living in cities located on the coast. More people will be affected by coastal flooding as a result.
