Unintended Geoengineering: How Shipping Emissions Have Altered the Earth
Scientists have discovered that the reduction in ship tracks, caused by regulations to cut down on sulfur pollution emitted by ships, has inadvertently led to the warming of the planet. Ship tracks, formed from the exhaust of vessels, were found to brighten low-lying ocean clouds, reflecting sunlight away from the Earth and cooling temperatures. However, the sulfur dioxide emitted by ships also contributed to air pollution. These findings have sparked interest in geoengineering, particularly the concept of marine cloud brightening, which aims to replicate the cooling effects of ship tracks without the harmful emissions. While the research is still inconclusive, experts believe that further investigation and investment in geoengineering research are necessary to understand the potential risks and benefits of such technologies.
