Fig. 4: Comparison of ZAME and AerChemMIP ozone and temperature changes with respect to methane concentration.
From: The role of future anthropogenic methane emissions in air quality and climate
AerChemMIP results are shown in blue, the UKESM ensemble member in green and ZAME in orange. Linear trends are extrapolated to test linearity of ZAME with respect to AerChemMIP. a Difference in global mean surface temperature (ΔGMST) vs the difference in square root of methane concentration (\({{\Delta }}\sqrt{[{{{{\rm{CH}}}}}_{4}]}\)) for 2015–2050, according to the relationship between methane concentration and radiative forcing34. b Difference in ozone concentration (Δ[O3]) vs difference in methane concentration (Δ[CH4]) between 2015 and 2050. Error bars represent the standard error.
