The rise in global sea levels due to the climate crisis not only endangers homes and livelihoods but also poses a significant threat to languages spoken in low-lying regions like Tuvalu, Kiribati, and the Marshall Islands. Language loss is not a new phenomenon, as climate and geography have historically influenced human settlements and the diversity of languages spoken. The equatorial regions, with their favorable climates and agricultural opportunities, have been particularly conducive to the flourishing of languages and cultures.
However, as the climate crisis intensifies, the regions once hospitable to communities and their languages are now becoming inhospitable. While the rising sea levels themselves may not directly swallow entire linguistic communities, the threat lies in forced migration. When populations are compelled to leave their lands and resettle elsewhere due to environmental factors like rising seas, droughts, or storms, their indigenous languages face increasing challenges to survival.
The climate crisis exacerbates an existing crisis of language loss. Even before global temperatures began to rise, over half of the world's languages were already endangered, with some estimates suggesting that 90% of languages are at risk. Factors contributing to language loss include the imposition of national languages, government persecution of linguistic minorities, the dominance of international languages in the era of globalization, and limited media and educational resources for minority languages. Language extinction is a gradual process. As communities adopt different languages for various contexts, intergenerational transmission of indigenous languages declines until they eventually cease to be spoken. The climate crisis, with its amplified threats, acts as an accelerant for this loss.
However, efforts are underway to counteract language loss. Indigenous communities and linguists collaborate to document endangered languages, and revitalization initiatives breathe new life into languages once in decline. For instance, Tuvaluan, a language under threat as its speakers migrate from their islands, finds hope in New Zealand, where the expatriate community prioritizes language and cultural education for the youth.
Recognizing the urgency of the language crisis, Unesco launched the Indigenous Languages Decade to raise awareness and mobilize resources to address the issue. The growing concern over the climate crisis and the threats it poses presents an opportunity to link the two existential challenges. By acknowledging the interconnectedness of languages and species, efforts to mitigate one problem may also alleviate the other. Preserving linguistic diversity is not trivial, as languages are deeply intertwined with culture, identity, and knowledge. They hold valuable information, encode histories, catalog plants, and define peoples. Losing languages means losing access to crucial scientific and cultural knowledge and limiting our understanding of ourselves as a species.
In conclusion, the climate crisis poses a dual threat to humanity's cultural heritage by endangering both languages and species. However, the gradual nature of language loss allows for intervention and redirection of the narrative. Collaboration between indigenous communities, linguists, and global initiatives offers hope for the preservation and revitalization of endangered languages. By recognizing the importance of linguistic diversity and its intersection with the climate crisis, we can work towards safeguarding our shared cultural heritage and securing a more sustainable future for all.
