aPTBs, heatwave-attributable preterm births. a The temporal trend of aPTBs in actual climate which were based on the observed HWDs during 2010-2020. The solid line shows the point estimates with the shading encompassing their 95%CIs, and the dashed line shows the linear regression. b The temporal trend of the proportion of aPTBs induced by anthropogenic warming to aPTBs in the factual scenario. The solid line and shade area correspond to the proportion estimates and their 95%CIs, respectively. The blue dashed line fits the proportions in 2010-2015, while the red dashed line fits the proportions during 2016-2020. c Spatial distribution of annual average aPTBs in actual climate in 0.5-degree grids. d Spatial distribution of the annual average aPTBs in relation to anthropogenic warming. e Spatial distribution of annual average aPTBs per million living births in actual climate. f Spatial distribution of aPTBs per million living births that were induced by anthropogenic climate change.
