Sea level rise brought on by human caused climate change will displace millions of people and ravage coast lines around the world. Sea level rise is caused primarily by the added water from melting ice sheets and glaciers, specifically in Greenland and Antarctica, and the expansion of seawater as it warms. Rising sea levels has and will continue to produce climate refugees.
Rising sea levels will particularly affect low-lying wetlands and dry land, as water dispersal is less available. Eroded shorelines contribute to coastal flooding, which then increases the flow of salt water into nearby groundwater aquifers, affecting the drinking water. This disruption weakens infrastructure and makes it more vulnerable to damage from storms.
