Shipping and Cloud Brightening

The discussion reveals how shipping emissions, particularly sulfate, have been brightening clouds over the North Atlantic, creating a cooling effect on the atmosphere. This phenomenon is easier to observe over oceans due to the lack of geographical interference, making it a significant area for studying the impacts of pollution on cloud formation. However, the health implications of sulfate emissions, especially near the surface, prompted the International Maritime Organization to take action in 2020 to reduce these pollutants.
