Global warming is the most telling cause of climate change. Another facet is global dimming: reducing the Sun’s radiation from reaching Earth’s surface because of a blanket of atmospheric particulates. These pollutants are both natural – from volcanic eruptions and forest fires – and via man-made aerosols.
The cooling effect of global dimming has been overwhelmed by greenhouse gas release. Even worse, global dimming has an adverse effect on the lives of plants and other organisms that thrive on sunlight.
Global dimming cannot be considered a positive aspect of climatic dynamics, such as a counter to global warming. The dimming is instead another disruption in Earth’s climate gyre, and an attack on ecosystem survival worldwide.
