Fig. 4: Projection of the marine heatwave in a +4 °C warmer climate.
From: Projected amplification of summer marine heatwaves in a warming Northeast Pacific Ocean

Same as Fig. 3 for summer SST(°C) changes between +4 °C and present-day climates. In a and b, values below the summer GMSST increase of 1.9 °C (white contour) are in white hatching. c Event-specific change in SSTs. Non-overlapping storyline ensembles in a and non-overlapping storyline warming and regional mean change in c are in dotted areas (i.e., highly significant signal, see Methods). d Area-averaged SST change (°C) between +4 °C and present-day climates, in the marine heatwave core (black box), coastal region (red box) and central North Pacific (blue box). The storyline change (red bars) is the total marine heatwave change signal, and results from the combined regional mean and event-specific changes (yellow and blue bars respectively). Values below the 1.9 °C summer GMSST projected change are shaded in grey.
