Consequences of climate change
Flooding
Higher temperatures and rising sea levels lead to a higher risk of flooding for coastal and inland areas.
Social: people have to move out from their homes or even their countries. Loss of jobs as workplaces and employment sectors are destroyed. Increase in waterborne diseases such as cholera (especially in LIDC countries).
Economic: huge amounts of money needed to improve flood defences and provide temporary homes for those displaced by floods. Financial stress on citizens and governments.
Environmental: animal habitats are destroyed by floods and animals drown. Can cause a build-up of sediment in certain areas. Ecosystems are affected.
Lack of water resources
The rising heat means that water evaporates and more is used so there is a shortage.
Social: people globally have lack of water so basic sanitation and drinking resources are not available, therefore leading to more diseases spreading, especially in poorer countries. War rages between communities and even countries as there is competition for water supplies.
Economic: people struggle to keep businesses going as they haven't got the resources. Water-based tourist attractions have to close, therefore ending a branch of income. Hydropower potential is lost as there is no water spare.
Environmental: animal habitats are destroyed and animals die due to dehydration. Species become endangered. Biodiversity is threatened.
Effects on health
Depletion of the ozone layer leads to risk of different diseases.
Social: hospitals struggle with increase of patients with skin cancer and eye problems. People in poorer countries don't have access to the treatment they need. Increase in temperature means that conditions are just right for disease-carrying insects such as mosquitoes, this leads to an increase in malaria cases.
Economical: the hospitals do not have the money to keep up with demand and the governments do not have the money to increase spending on medical care. People cannot continue with certain jobs because they have health issues.
Effects on agriculture and food security
Change in temperatures mean that there are affects on what countries can produce and therefore their food security. Changes in water supplies and irrigation and solar radiation have direct impacts on agriculture
Social: more job opportunities open as there are opportunities for new crops to be grown. Change in weather means that crops can't be grown and people cannot get the food they need.
Economic: extra income from new opportunities with new crops. Rising temperatures mean that agriculture can't happen and income and trade decrease. Governments (especially in LIDC countries) cannot cope with financial stress as they try to build up food security and agricultural opportunities.
Environmental: new crops bring new nutrients to the ground and surrounding land. The land that is able to be farmed on is over-farmed and becomes barren.
Rise in sea level
Due to ice caps melting, sea levels are rising and this is having serious effects on the world.
Social: people living in vulnerable areas may have to move home or even move to different countries. People 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.
Economic: many important world cities could be affected by flooding. Trade is impacted as harbours and ports are affected. Valuable agricultural land may be lost to the sea. Destroyed transport systems. Valuable land and properties will need expensive measures of coastal defence.
Floods and eroded beaches mean that tourists may not want to visit, therefore impacting income.
Environmental: fresh water sources could be polluted by salty seawater. Damage to coastal ecosystems including mangrove swamps (which form natural storm barriers) and coral reefs. Harbours may become blocked by sediment due to increased rates of coastal erosion. Up to 33% of coastal land and wetlands could be lost in the next 100 years.
Drought
Higher temperatures and lower rainfall can lead to drought
Social: people cannot get the food and water they need to survive. Countries are hit by famine.
Economic: governments cannot get the money they need to provide their people with basic resources. Income is stalled as there is no produce to sell (especially in poorer countries). Global increase in food prices, potentially leading to famine in LIDC countries.
Environmental: animals are dehydrated and die. Plants cannot survive and die. Loss of biodiversity. Ecosystems are threatened.
