Think now of what could happen when climate change forces hundreds of millions, even billions of people to leave regions and countries where conditions will no longer support human life, places like; Darfur, Ethiopia, Kenya, Somalia, Southern Sudan, the Republic of Maldives, the Solomon Islands, the Marshall Islands, and other low-lying island States, some of which will disappear altogether, submerged under rising seas. In Bangladesh alone, it is estimated that 20-to-30 million people will be forced to migrate as a result of sea level rise due to climate change.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 U.S. Navy is already planning for increased humanitarian assistance and disaster relief (HA/DR) as a result of climate change. The Navy believes that mass migrations precipitated by climate change will not only stretch its HA/DR capabilities, but could also result in instability and regional conflict requiring U.S. military assistance for the evacuation of U.S. citizens and the rendering of assistance in quelling unrest.
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.
And yet America itself will not be immune to climate change and internal migration, such as happened during the Dust Bowl era, the largest migration in American history. By 1940 2.5 million people had moved out of the Plains states. They did not receive a warm welcome in places like California, where city police were sent to the border to repel the ‘invaders.’

Internal and cross-border migration driven by climate change will test America’s infrastructure, its mettle, and its morality. Will the tired, the poor, the homeless, the tempest-tossed be met at the borders with flags waved in welcome, or, as in Murrieta, California, and Oracle, Arizona, with xenophobic fervor? How will this ‘nation of immigrants’ prepare for and greet the multitudes displaced by a changing climate that we have done much to cause and little to abate? The answer will define forever who we are as a people.
