Global Dimming

Global dimming refers to the reduction in solar energy reaching Earth's surface due to air pollution. Since the 1950s, significant decreases have been observed in various regions. The phenomenon is caused by pollutants like soot, which block sunlight and alter cloud formation, leading to more reflective clouds. This pollution layer can significantly reduce sunlight reaching the ocean. While reducing air pollution is necessary, it may reveal the full extent of global warming, as global dimming has been mitigating some warming effects. Understanding and addressing these issues is crucial for managing climate change.
