Hong Kong finds itself in the middle of opposing trends. Amid political unrest, Beijing's increasing security pressure, and pandemic disruptions, many Hong Kongers have left and been replaced by a new group of immigrants, largely from mainland China.

Severe weather, rising seas, and other consequences of global climate change are affecting the way people live, work, and move around the planet. While there is no clear, direct line between the impacts of climate change and changing human movement, there are indications that the warming planet is indirectly creating or altering patterns of migration. Our podcast Changing Climate, Changing Migration dives deep into the intersection of climate change and migration to separate fact from fiction.

Amid the highest Caribbean maritime migration levels in a generation, the Biden administration is relying on a carrot-and-stick strategy it honed amid record unauthorized migration at the U.S.-Mexico border. The approach, combining limits on asylum, expanded legal pathways, and international enforcement partnerships, could be increasingly important if maritime migration rises, as this article explains.

Palestinians constitute the world’s longest protracted refugee situation and largest stateless community.
