Human habitation zone

The band of environmental conditions in which humans can thrive, which is shrinking as the planet warms.

Details

Our Take
Visceral and concrete in a way that abstract temperature targets are not. '1.5 degrees' is a number; the shrinking habitation zone is a map of where people can live. Communities at the edge face not just physical stress but the collapse of social and institutional fabric that makes collective life possible. The maps showing this zone shifting are among the most powerful visual tools for climate urgency.
