Fig. 2: Contributions of non-urban areas, urban exposure, and UHI plus interactions in urban areas to regional and world SCC.
From: Urban and non-urban contributions to the social cost of carbon
Dark blue fill denotes the contribution (percentages) of non-urban areas to regional/global SCC, orange fill shows the contribution of urban areas to regional/global SCC without considering increased exposure or UHI effects, green fill indicates the additional cost attributable to increased exposure in urban areas, and light blue fill represents the increase in regional/global SCC due to UHI warming and interaction effects with global climate change. The dashed purple rectangle indicates the components that constitute the SCC values that correspond to the K damage function, while the dashed black rectangle indicates those of the KU damage function. Numbers are in percentage of total SCC and sum 100% up to rounding errors. For reference, the contribution of UHI-int in dollars is shown in italics. Based on NCAR regional urban population projections.
