Time series of monthly deseasonalized ocean heat content (OHC) anomaly, summertime sea surface temperature (SST; September and February for the Arctic and Antarctica, respectively), and monthly deseasonalized zonal mean atmospheric heat transport (AHT) for the Arctic and Antarctic (from ORAS5 and ERA5). OHC and SST are calculated as area means (as defined in Fig. 2) and AHT is calculated from a zonal band at 55°N and 55°S for the Arctic and Antarctic respectively. Linear trends of SST and AHT are plotted and reported and the AHT 12-month running mean is also shown.
