Fig. 1: Mean intensity and annual total days of marine heatwaves (MHWs) during 1985–2014.
From: Arctic Amplification of marine heatwaves under global warming

a, b MHW mean intensity in the (a) global ocean and (b) Arctic Ocean derived from OISST. c, d The same as (a) and (b), but for MHW annual total days. e–h The same as (a–d), but from the multi-model mean (MMM) of CMIP6 historical simulations.
