What Will Hawaii Look Like if All Ice on Earth Melts? Here’s Your Answer

Hawaii, known for its tropical climate and lush landscapes, is not immune to the effects of global warming. Rising temperatures and melting ice caps are already impacting the state, particularly in terms of sea-level rise and permafrost thawing. If all ice on Earth were to melt, the consequences for Hawaii would be severe and far-reaching.

Sea-Level Rise

A recent study found that Hawaii is particularly vulnerable to uneven global sea-level rise due to melting glaciers and ice sheets. The research suggests that Honolulu, the state capital, will experience some of the highest sea-level rise, with projections of up to 2 feet of rise in the mid-range scenario and over 0.3 inches per year in the high-end scenario by the end of the century. This increased sea-level rise will lead to more frequent and severe flooding, threatening coastal cities and infrastructure.

Permafrost Thawing

Hawaii is home to rare tropical permafrost patches on Mauna Kea, the state’s tallest mountain. These patches are shrinking due to climate change, with estimates suggesting they could be gone within a few decades.

The thawing of permafrost will not only release large quantities of climate-warming carbon dioxide and methane into the atmosphere but also cause the ground to soften and slump, threatening infrastructure and cultural sites.

Impacts on Native Hawaiian Culture

Mauna Kea is a sacred site in Native Hawaiian traditions, a place of worship and home to the gods. The disappearance of snowfall on the mountain, which is already in danger due to rising temperatures, will have significant cultural implications. The goddess of snow, Poli‘ahu, is associated with the mountain, and the loss of snow will be seen as a loss of spiritual significance.


If all ice on Earth were to melt, Hawaii would face catastrophic consequences. Rising sea levels would inundate coastal areas, threatening infrastructure and displacing communities. The thawing of permafrost would release significant greenhouse gases, further accelerating global warming.

The cultural significance of Mauna Kea would be irreparably damaged by the loss of snow and the disappearance of permafrost. It is essential that immediate action is taken to reduce greenhouse gas emissions and mitigate the effects of climate change to protect Hawaii’s unique environment and cultural heritage.
