Reducing sunlight by aerosols not a great solution

A recent study that found there is a weekend boost to plant productivity in Europe because of reduced air pollution by aerosols which block sunlight, should be a warning to those who seek to address global heating by injecting aerosols into the atmosphere. This research shows how sensitive plants are to any drop in sunlight. Addressing climate change through geoengineering will reduce plant photosynthesis on land and at sea globally, with probably catastrophic consequences on nature and agriculture. This idea is courtesy of Arthur Dahl, of Geneva, Switzerland, who submitted it to New Scientist publication last month. As this platform may be a source of research for people interested in such topics, I am republishing it here.
