We find that most of the other half of the warming was caused by a restriction on aerosol emissions by ships, which was imposed in 2020 by the International Maritime Organization to combat the effect of aerosol pollutants on human health
That is quite startling. It took decades of accumulation for CO2 to cause 1.5C of warming. This effect caused .2C in just a few years.
That does suggest that geoengineering isn't quite as unlikely as I'd thought. But an effect that powerful risks unexpected effects that are even worse.
