From: Declining urban density attenuates rising population exposure to surface heat extremes
Trends of surface urban island maximum weighted by area (\(\Delta SUHI_{A}\) [K/decade], x-axis) and population (\(\Delta SUHI_{P}\) [K/decade], y-axis). The dashed line represents \(\Delta SUHI_{A} = \Delta SUHI_{P}\). The sizes of the bubbles are proportional to the population growth (million) from 2003 to 2020. Colors from green to purple represent the difference between the trends of the population- and area-weighted max surface heat island \(\Delta (SUHI_{P} - SUHI_{A} )\) [K/decade]. This difference between the two trends of SUHI shows the contribution from intra-city population distribution to the population exposure to surface temperature extremes.
