Background: I am an analyst in a state governor’s office that has seen an increase in immigrants over the last few years. I am putting together a report for the governor, who wants to know whether this trend is driven by climate change or other factors. The governor is interested in crafting a policy on immigration due to climate change.
Request: This report should summarize the available evidence that people are migrating across national borders due to the effects of climate change in their countries of origin. Arguments should be supported by statistics or forecasts from authoritative sources such as the United Nations, federal agencies, universities, etc. Immigration due to economic conditions or violence should not be included in the analysis, unless those factors are known to have been caused by climate change.
