Hawaii’s Oahu Island is sinking 40 times faster than expected, with rising sea levels set to flood popular areas like Honolulu, Waikiki, and Pearl Harbor.

A new study warns of devastating effects by 2080, with some areas facing regular flooding and $12.9 billion in infrastructure costs.

Parts of the island, including Mapunapuna and Pearl Harbor, could experience flooding within this decade, 30 years earlier than anticipated.

By 2100, sea levels could rise by up to eight feet, threatening thousands of homes and businesses.

FEMA has updated flood zones, signaling increased risks for the island’s coastal communities.
