Please reread your own sources. Your own source concludes in the paragraph following the one you cited that:
"Based on projected rates, mangrove trees could lose their race against rising water within the next 30 years."

Tldr: climate change begets soil erosion, which leads to loss of land mass... which disappears islands.
