How cleaner air changes the climate

Aerosols have a strong influence on the present climate, but this influence will likely be reduced over the coming decades as air pollution measures are implemented around the world, writes Bjørn Hallvard Samset in a commentary in Science.  

At a global level, aerosols have helped to reduce the warming effect from greenhouse gas emissions, and necessary reductions in air pollution may thus make it harder to achieve ambitious global climate and environmental aims, such as the Paris Agreement's 2°C target.

Aerosol emissions are an important component of human influence on the climate today. Fossil fuel use reductions and air quality measures make it likely that this influence will be greatly reduced over the coming decades, with consequences for the climate that may even dominate over those from greenhouse gas warming in some regions.
