If humans gave up on geoengineering after 50 years, it could be far worse than if we had done nothing at all

In Potentially dangerous consequences for biodiversity of solar geoengineering implementation and termination (published in Nature Ecology and Evolution, Sci-Hub mirror), a group of cross-institutional US climate scientists model what would happen if human embarked upon a solar geoengineering project to mitigate the greenhouse effect by aerosolizing reflective particles into the atmosphere, then gave up on the project after a mere half-century.
