Social effects of climate change

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.

Increased emigration of those from poorer or low-lying countries to wealthier or safer countries seeking better conditions.

Communities that use the melt water from glaciers may see this supply decrease. This is especially the case in Asia.

Less fresh water will be available. If the Quelccaya Ice Cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without a source of either.


Climate change also has impacts on health. For example, increased flooding events may cause water borne infectious diseases to spread, such as malaria carried by mosquitoes.

A rise in heat waves can cause deaths among the old and very young. The heat wave in 2003 is estimated to have caused over 2,000 extra deaths in England and Wales and 35,000 deaths in other parts of Europe like Italy, Spain and France. reseach by the London School of Hygiene and Tropical Medicine found that between 540 and 760 deaths could be attributed to the hot spell in 2013 in England and Wales.
