Fig. 4
Scatter plots based on log-transformed annual time series of growth parameters and human population (a,c,e) and monthly mean maximum sea surface temperature (SSTmax; b,d,f). Triangles and circles represent the periods 1950 to 1985 and 1986 to 2020, respectively. Regression lines with 95% confidence intervals, and the corresponding coefficients of determination and p-values are indicated only when statistical significance (p < 0.05) exists. The coloured lines correspond to either 1950 to 1985 or 1986 to 2020, and the black bold lines correspond to 1950 to 2020. The type of regression is represented by the solid (linear) and dashed (polynomial) lines.
