An Unintended Test of Geoengineering is Fueling Record Ocean Warmth

Researchers are now waking up to another factor why so many places on earth are getting warmer, one that could be filed under the category of unintended consequences: disappearing clouds known as ship tracks. From a report: Regulations imposed in 2020 by the United Nations's International Maritime Organization (IMO) have cut ships' sulfur pollution by more than 80% and improved air quality worldwide. The reduction has also lessened the effect of sulfate particles in seeding and brightening the d
