Human migration is going to be a reality for the people of island nations and coastal areas around the globe. Sea level rise will cause the people who live in these areas to move to higher ground or possibly build sea walls in order to protect their homes.
Desertification is also causing people to move. “From 1997 to 2020, some 60 million people are expected to move from the desertified areas in Sub-Saharan Africa towards Northern Africa and Europe”.
The Maldives and Tuvalu are going through rapid changes currently. Human migration due to climate change is not a thing of the future, it is going on now. New Zealand has agreed to grant ‘environmental refugee status’ to 75 Tuvalans a year. Island nations like Tonga, Kiribati, and the Marshall Islands are all seriously concerned for near future of their areas. The potential for millions of migrant due to sinking islands is very real and plausible.
The arguments exist that the land may be moving and sinking as well as increasing ocean depth and that it is very hard to make the exact correlation between climate change and sinking islands, but it is also very hard to argue against it.
