    Grambank reveals the importance of genealogical constraints on linguistic diversity and highlights the impact of language loss
    (Center for Open Science, 2022-12-04)
    While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here we outline the Grambank database. With over 400,000 data points and 2,400 languages, Grambank is the largest comparative grammatical database available. The comprehensiveness of Grambank allows us to quantify the relative effects of genealogical inheritance and geographic proximity on the structural diversity of the world's languages, evaluate constraints on linguistic diversity, and identify the world's most unusual languages. An analysis of the consequences of language loss reveals that the reduction in diversity will be strikingly uneven across the major linguistic regions of the world. Without sustained efforts to document and revitalize endangered languages, our linguistic window into human history, cognition and culture will be seriously fragmented.

    Grambank Reveals the Importance of Genealogical Constraints on Linguistic Diversity and Highlights the Impact of Language Loss
    (American Association for the Advancement of Science, 2023-04-21)
    While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here, we outline the Grambank database. With over 400,000 data points and 2400 languages, Grambank is the largest comparative grammatical database available. The comprehensiveness of Grambank allows us to quantify the relative effects of genealogical inheritance and geographic proximity on the structural diversity of the world’s languages, evaluate constraints on linguistic diversity, and identify the world’s most unusual languages. An analysis of the consequences of language loss reveals that the reduction in diversity will be strikingly uneven across the major linguistic regions of the world. Without sustained efforts to document and revitalize endangered languages, our linguistic window into human history, cognition, and culture will be seriously fragmented.

    Language, ecology and climate change: First principles and worldwide perspectives
    (Elsevier BV, 2026-03-01)
    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.
