Fig. 4: Scaling between projected atmospheric warming and changes in the availability of calcium, iron, omega-3 fatty acids and protein from fisheries catches and mariculture production globally and in lower-income countries.
From: Climate change exacerbates nutrient disparities from seafood
Atmospheric warming is represented by global surface air temperature relative to pre-industrial (1850–1900) levels. Each data point represents an annual projected nutrient availability driven by outputs from a specific Earth system model and climate change scenario relative to 2000. The lines are based on linear regressions, with the estimated slopes and intercepts noted in each panel. Lower-income countries refer to those with gross domestic product per capita (2010) below the median value of all maritime countries (Methods). a,c,e,g, Global changes in calcium (a), iron (c), omega-3 (e) and protein (g). b,d,f,h, Lower-income country changes in calcium (b), iron (d), omega-3 (f) and protein (h).
