Fig. 2: Global vegetation Hg(0) uptake (bars) via elevated CO2 under different atmospheric CO2 concentrations (lines) from the historical emission scenario in 1850 to the Shared Socioeconomic Pathway (SSP) emission scenarios in 2100.
From: Potential decoupling of CO2 and Hg uptake process by global vegetation in the 21st century
SSP1-2.6 represents the lowest scenario, termed the “2 °C scenario,” which aims for a sustainable future. SSP3-7.0 represents a moderate scenario, described as a medium-high reference scenario within the socio-economic context of “regional rivalry.” SSP5-8.5 represents the highest scenario, also known as “business-as-usual,” considered the worst-case scenario in a high fossil fuel-intensive world. Solid lines represent atmospheric CO2 levels during 1850–2000, shaded lines represent the atmospheric CO2 levels during 2000–2100 under different scenarios.
