Volcanic eruptions play a unique role in the Earth's climate. When a volcano erupts, it releases ash and gases, like carbon dioxide (CO2) and sulfur dioxide (SO2), into the atmosphere.
CO2 is a greenhouse gas that traps heat, contributing to the greenhouse effect, which warms the planet. However, SO2 can create tiny particles that reflect sunlight back into space, which can cool the Earth.
So, while volcanic eruptions can add to the greenhouse effect by releasing CO2, they can also have a cooling effect through SO2. This creates a temporary balance between warming and cooling, influencing the Earth's climate.
