Volcano eruptions can cool Earth for years
Giant volcanic eruptions release gases that create a sunlight-blocking veil, dramatically cooling Earth's temperatures for years and impacting global weather patterns.
Massive volcanic eruptions can act like a global sunshade. When volcanoes like Mount Pinatubo in 1991 erupt, they blast sulfur dioxide high into the atmosphere. This gas forms tiny particles that reflect sunlight back into space, reducing the solar energy reaching Earth.
