Language, ecology and climate change: First principles and worldwide perspectives

The acceleration of climate change over recent decades threatens consequences so wide-ranging that they extend across the human sciences, and call for perspectives from all disciplines. Notwithstanding various attempts to integrate the humanities into climate research, linguistics has been slow to engage with the topic. This special issue aspires to remedy this, by setting out basic principles for exploring how language dynamics have related to ecology, and in particular to climate change , over the last 10,000 years, drawing examples from various language families worldwide. We investigate how language distributions can pattern by ecology, how climate change can thus drive language mobility, and look into cases where languages have even been argued to show certain characteristics associated with the ecologies in which they are (or were) spoken. We summarize quantitative, qualitative and multi-disciplinary methodology that can help us explore this ecology-language interface, and introduce various overarching models that have been proposed for ecology-language relationships at the global scale. What emerges from these analyses and worldwide case-studies is that relationships between climate/ecology and language are essentially indirect, but nonetheless far-reaching, mediated as they are through crucial aspects of human culture and social structures, not least subsistence modes. And through time, over the human trajectory from Holocene into the emerging Anthropocene, the relationship largely inverts, shifting from environmental determinism upon humans and their languages towards increasing anthropogenic impacts on ecology and language dynamics.
