This article considers the fiftieth anniversary of the 1972 United Nations Educational, Scientific and Cultural Organization’s (UNESCO) World Heritage Convention in light of climate change, offering a state of the field review of climate responses for World Heritage sites (WHS). Opening with a brief review of UNESCO World Heritage activities around climate change, we then detail the primary impacts and risks that climate change pose for WHS and the reporting and monitoring systems in place to document and track these impacts. Looking forward, we examine the most promising pathways for World Heritage to advance in the domains of climate mitigation, adaptation, climate communication, and climate action.
