Fig. 6: Scatter plot of detrended March Arctic sea-ice area against detrended annual mean Atlantic ocean heat transport for all points between 1950 and 2014 and for the 9 best models in terms of Arctic SIA, SIV and Atlantic OHT. The correlation coefficients $R$ and regression slopes $a$ (unit: 1000 km$^2$ per TW) are shown in the upper right corner of each panel for each model.
