Australian Scientists Find Link Between Language Diversity and Climate

Language diversity is closely linked to a region’s climate, rather than being purely incidental, according to a new study published in the journal Nature Communications. Researchers have also found that language diversity is more heavily impacted by a region’s climate than the region’s landscape, such as altitudinal range and river density, which may contribute to isolation of cultural groups.
The research team of Xia Hua, Simon Greenhill, Marcel Cardillo, Hilde Shneemann, and LIndell Bromham from ANU in Canberra mapped languages around the world and found that areas with high year-round productivity led to more languages. The study was the first global analysis of language diversity that compares the relative importance of isolation and ecological risk.
The study first looked at the fact that the geographic
distribution of the world’s approximate 7500 languages is strikingly uneven.
Papua New Guinea represents over 10% of the world’s languages in
