Environmental change has always motivated human migration. However, in our age of climate change, natural disasters—floods, hurricanes, drought, wildfires, crop failure—are making migration less an option, and more an imperative for survival. Climate migration disproportionately affects developing countries in the Global South. In the United States too, climate migration has become increasingly prevalent due to hurricanes, drought, and catastrophic wildfires. On Earth Day 2022, we examine the human factor in climate change and consider how to prepare for mass climate migration in the future.
