By combining data related to carbon dioxide emissions, temperature increases, economic activity, and population distribution, researchers created a model to assess the effects of international border policy on migration flows and exposure to impacts of climate change for the period between 2015 and 2100; the model determined that most migrants, when allowed, move to areas that experience less severe climate change impacts than their initial locations, but restrictive border policies keep many potential migrants in areas that increase their exposure and vulnerability to climate change impacts, according to the authors.
