Impacts of Climate Change
Social Impacts
People living in vulnerable areas may have to move to different countries. Some small island states such as Tuvalu and Vanuatu are particularly are at risk.
600 million people live in coastal areas that are less than 10m above sea level.
People may suffer increased frequency of flooding and storm damage.
People may lose their jobs, for example in fishing or tourism, and have to learn new skills.
The numbers of environmental refugees - people who have lost their homes due to flooding - will increase.
Economic Impacts
Valuable agricutral land (e.g. in Bangladesh, Vietnam, India and China) may be lost to the sea or polluted by seawater.
Many important world cities including New York, Venice and London could be affected by flooding.
Harbors and ports may be affected, which will have an impact on fishing and trade.
Transport systems, such as railways, roads and airports may be damageed or destroyed.
Valuable land and property will need expensive measures or coastal defence.
Many countries depend on coastal tourism s their main source of income. Beaches may be eroded or flooded, forcing hotels to close. People may decide not to visit.
Environmental Impacts
Damage could occur to coastal ecosystems such as mangrove swamps, which form natural barriers to storms.
Fresh water sources such as wells could be polluted by salty seawater; this is called salinisation.
Damage to coral reefs by storms and powerful waves will affect fish breeding grounds and ecosystems.
The IPCC estimates that up to 33% of coastal land and wetlands could be lost in the next 100 years.
Harbours may become blocked by sediment due to increased coastal erosion.
