Opinion | Is Asia’s cleaner air driving global warming?
Air pollution has held human-induced warming in check for the past century by acting as an artificial sunshade, a new study shows
Clean-up of sulphur emissions from global shipping has been implicated in past research. But that clean-up only began in 2020, so it is considered too weak to explain the full extent of this acceleration. Nasa researchers have suggested that changes in clouds could play a role, either through reductions in cloud cover in the tropics or over the North Pacific.
Our study addresses the link between East Asian air quality improvements and global temperature, building on the efforts of eight teams of climate modellers across the world.
We have found that polluted air may have been masking the full effects of global warming. Cleaner air could now be revealing more of the human-induced global warming from greenhouse gases.
