I would call St Michel in France half an island, as half of the day you can simply walk to the island and the other half you would have to take the boat  ;D
I wonder due to all the climate changes and the changes of the sea levels if some islands will disappear and if some new will be created, would be interesting to know.

In principle, St. Michel is connected to the mainland with a dyke from the sight's parking place to the rock. You can go there on foot, bicycle, horse-drawn omnibus or modern bus.

In practice, the dyke is washed over when the flood coefficient is more than 110. This happens mostly in March and April. With climate change, the "marnage" would increase by 4 to 5 meters, according to Al Gore. This would radically increase the number of days the dyke is washed over. You may expect that the French government is perfectly capable of increasing the height of the dyke, though.

More consequential is that Mont St. Michel is situated in a site where the water rises higher and more quickly with bad weather. Climate change will cause a rise in freak weather incidents that threaten not just the dyke, but also parts of St. Michel itself.

Keep in mind that a large number of islands in the Pacific are already flooding. Recently, water level of lakes in Africa has started rising, flooding the villages on the banks and turning the villagers into climate fugitives. In one case, a salt water lake is threatening to spill into a fresh water lake, which would kill the latter's animal population completely, destroying practically all jobs in a wide area.
