One stressor that may be the tipping point for some communities is climate change. Many small linguistic communities are located on islands and coastlines vulnerable to hurricanes and a rise in sea levels. Other communities are settled on lands where increases in temperature and fluctuations in precipitation can threaten traditional farming and fishing practices.
These changes will force communities to relocate, creating climate change refugees. The resultant dispersal of people will lead to the splintering of linguistic communities and increased contact with other languages. These changes will place additional pressures on languages that are already struggling to survive.
