Global Dimming - GCSE Chemistry Definition

Global dimming is the gradual reduction in the amount of sunlight reaching the Earth's surface. This happens because small particles, like dust and soot, are released when fossil fuels are burned, and they build up in the atmosphere. These particles block some of the sun's rays and cause clouds to reflect more sunlight back into space. This means less sunlight reaches the ground, which can cool the Earth's surface. Global dimming can affect weather patterns, crops, and water supplies. It is important to understand global dimming because it is linked to air pollution and climate change.
