Fig. 1: Correlation of global human population, energy consumption and productivity during the Holocene and Anthropocene epochs.

From: Extraordinary human energy consumption and resultant geological impacts beginning around 1950 CE initiated the proposed Anthropocene Epoch

Fig. 1

a Global human population (millions), b global energy consumption (EJ/y), and c global productivity ($/y/capita), across the Holocene and proposed Anthropocene epochs (in this paper starting in 1950 CE). All three parameters are highly correlated (Spearman’s rank coefficient = 1.00). Larger circle = 1850 CE; large square = 1950 CE. Data references are listed in Supplementary Online Material.
