Having fewer resources and options for adaptation in place, children, women, the poor, older persons, and other vulnerable groups experience the greatest pressures to migrate as a result of environmental, economic and social impacts of climate change. These are people very much like those streaming over America’s southern borders now.
The International Organization for Migration says that “climate change is expected to trigger growing population movements within and across borders.” The UN Deputy High Commissioner for Refugees said that by 2050 up to a billion people globally could be forced to migrate. Where will they all go? Some studies suggest they’ll come here, to America. For example, mass migration to the United States from countries south of our border, like Mexico, may be triggered by climate-caused crop failures.
