Amid the COVID-19 pandemic, communities across the globe are experiencing unprecedented climate disasters.

According to modeling by ProPublica, the Pulitzer Center, and The New York Times Magazine, in the event that governments take “modest action to reduce climate emissions, about 680,000 climate migrants might move from Central America and Mexico to the United States by 2050.” That number leaps to above a million people in a scenario where no action is taken. The impacts of climate change on people’s decision to move are not constrained to the developing world, or even across borders. A recent study found that one in 12 Americans currently residing in the southern U.S. will move to California and the Northwest over the next 45 years because of climate influences.
