Identifying climate vulnerability hotspots

New research identifying climate vulnerability hotspots has found that the number of people affected by multiple climate change risks could double if the global temperature rises by 2°C, compared to a rise of 1.5°C.
Researchers from IIASA, Global Environment Facility (GEF), the United Nations Industrial Development Organization (UNIDO), the University of Oxford, and the University of Washington, developed 14 impact indicators in three main sectors – water, energy, and food & environment – using a variety of computer models. For example, the indicators include a water stress index, water supply seasonality and crop yield changes.

They investigated the overlap between multiple climate change risks and socioeconomic development to identify the vulnerability hotspots if the global mean temperature should rise by 1.5°C, 2°C and 3°C by 2050, compared to the pre-industrial baseline.
