As a result of global warming the polar ice caps are melting and this will lead to a rise in sea levels causing flooding and coastal damage to many countries. The increase in temperature means an increase in water temperature which will and has continue to lead to extreme weather conditions, such as hurricanes. As a cause of the temperature changes, it can lead to animals and insects migrating to other areas. Taking disease with them that normally won't occur in other places. An example of this is the mosquitoes that migrate from Africa can bring malaria to other areas of the world.
