Climate change poses an existential threat to some of the world’s most cherished travel destinations, with projections indicating potential submersion within the next 80 years.

The Looming Threat of Rising Sea Levels

By 2100, the Intergovernmental Panel estimates an average global sea level rise of 17 to 33 inches (32 to 84cm) due to climate change. While major cities like New Orleans and Tokyo are bracing for increased flooding, low-lying island nations face a more dire fate.

Island Nations at Risk

The Maldives, Fiji, and the Seychelles are particularly vulnerable, potentially disappearing entirely as sea levels rise. Other locations, including Venice, New York, Amsterdam, and Hong Kong, could experience up to six feet of sea level rise in the coming decades, significantly altering their landscapes and displacing communities.

The Paradox of 'Last Chance' Tourism

Experts are warning against the growing trend of “last chance” tourism – the desire to visit these vulnerable locations before they are irrevocably altered. They argue that increased travel, especially long-haul flights, contributes to the carbon emissions driving climate change.

Environmental Impact of Tourism

Tourism’s carbon footprint is substantial, and fragile island ecosystems often lack the infrastructure to handle surges in visitors. This can lead to water shortages, strained sewage systems, damaged infrastructure, and a decline in the quality of life for local residents.

Specific Destinations Facing Imminent Danger

The Maldives, with an average elevation of just 1.5 metres, is exceptionally vulnerable, with an estimated 80 percent of its 1,100 islands potentially becoming uninhabitable by 2050. Kiribati, at only three metres high, is experiencing sea level rise four times faster than the global average.

The Bahamas, particularly New Providence, faces submersion within 75 years, due to its limestone geology. Fiji is increasingly threatened by both rising sea levels and extreme weather events, such as the devastating floods of 2009.

These nations serve as a stark warning about the accelerating impacts of climate change and the urgent need for global action and a shift towards sustainable travel practices.
