Nonlinearity of the cloud response postpones climate penalty of mitigating air pollution in polluted regions

Cloud droplet number concentrations are often assumed to depend linearly on atmospheric aerosols (in log–log space). Here the authors show that this relationship is instead sigmoid, which delays additional warming due to air pollution mitigation by 20–30 years in heavily polluted regions. Nature Climate Change
