As Climate Change Progresses, Billions May Be Forced to Relocate in the Coming Decades

Douglas McIntyre, Editor-in-Chief at Climate Crisis 24/7, discusses the shrinking climate niche—regions where humans can comfortably live. By 2070, three billion people may be forced to relocate due to extreme heat, hurricanes, and other climate-related disasters. This includes parts of the U.S., such as Florida and the Southwest. The resulting mass migration could lead to economic turmoil and conflicts over resettlement, posing one of the greatest humanitarian challenges of the century.
