Charlene, Princess of Monaco
Charlene, Princess of Monaco is the wife of Prince Albert II and a swimmer. Thus she is prepared for sea rise due to global warming better than most.
As a member of the South African Olympic swim team, she would practice regularly in the Atlantic Ocean. However, strong tides swept her nearly to the US Florida coast. Luckily, she was rescued by Prince Albert II of Monaco who was fishing at the time and had just snagged Cthulhu earlier. The prince found he had more in common with Charlene than Cthulhu and they married in 2011.
Princess Charlene still swims every day to keep fit. However, there have been some concerns expressed about this by Albert after he saw the movie The Shape of Water.
