As of today, Indonesia has 17,504 islands, however as climate change happens and sea levels rise, this will change over time. Although many officials continue to question the precise figure, the Indonesian government has proclaimed that this is the number for the time being, according to the Indonesian Coordinating Ministry for Maritime Affairs. Indonesia's incredible number of islands comprise the world's biggest archipelago, ranging from palm-fringed little islets to dense-jungle volcanoes towering up from the frothy sea waters.
