An analysis of more than 9 million Customs and Border Protection apprehension records from 2010 to 2024 by Columbia Journalism Investigations and Documented found that migrants are increasingly arriving from communities repeatedly hit by floods, storms, and drought. In 2024 alone, more than 520 Guatemalan birthplaces, close to 350 Senegalese ones, and about 100 Bangladeshi ones appeared in the records; border crossings from Bangladesh rose 150 percent from 2019 to 2024, and more than 1,800 Senegalese migrants from the western and central regions crossed after virtually none had before. About 55 high-migration countries had suffered three or more major climate catastrophes between 2019 and 2024, though the data cannot show why any individual left. The reporting follows people now in New York City. A Guatemalan mother from Quetzaltenango left around 2018 after seven storms, floods, and hurricanes since Tropical Storm Agatha in 2010, plus recurring drought, ruined her family's livelihood; she borrowed money to bring her children to the border, but her lawyer defrauded her of more than $10,000 and she has not been able to reapply for asylum. A Bangladeshi man from Feni, whose home and fields flooded five times in a decade as rising seas salted his rice land, left in 2023 after borrowing about $33,000; his pending asylum case rests on political persecution because climate harm is not a recognized basis for protection. A Senegalese farmer from Diourbel, whose crops were killed by alternating floods and droughts, surrendered to border agents in October 2023 and now relies on a Bronx mosque community after losing his shelter bed. No U.S. asylum category covers people fleeing climate disasters, and the story warns that rising arrests, detentions, and deportations put them at risk of being returned to climate-damaged homes.
