Up to 13.1 million people could be displaced from their homes due to sea-level rise by 2100, according to a study published Monday in Nature Climate Change. Almost half of those people would be in Florida.

The study's projection is based on the sea level rising about six feet due to climate change, with relocation costing about $14 trillion.

If seas only rise three feet by 2100, researchers estimated that 4.2 million people could be displaced. Check out the full study here.
