Fig. 4: Emergence of persistent year-round river heatwaves.
From: Persistent river heatwaves are emerging worldwide under climate change
a The proportion of the examined rivers experiencing persistent year-round river heatwave state under RCP 2.6, RCP 4.5, RCP 6.0, and RCP 8.5. The shaded area indicates the corresponding inter-model standard deviation. b The spatial distribution of the median starting year of year-round heatwaves projected by the multi-model ensemble under RCP 8.5, with its density distribution shown in the embedded chart. c The proportion of river area experiencing year-round heatwave state to the total river area in major river basins under RCP 8.5, and error bars indicate the inter-model standard deviation. d The number of years with year-round heatwave state in different rivers in the far future period (2070–2099) under RCP 8.5, with its density distribution shown in the embedded chart. Basemaps in b and d are from Natural Earth (https://www.naturalearthdata.com).
