Albedo modification refers to techniques aimed at increasing the reflectivity of the Earth's surface or atmosphere to reduce global warming. By reflecting more sunlight back into space, these methods could potentially lower temperatures and mitigate climate change effects. Common approaches include injecting aerosols into the stratosphere or enhancing the reflectivity of urban areas and vegetation. This concept is part of a broader field known as geoengineering, which explores various strategies to combat climate change. While albedo modification could offer temporary relief, it raises concerns about potential side effects, ethical implications, and governance challenges in its implementation.
