Q: Can a volcano eruption affect the weather?

Arabia Weather - A volcanic eruption can affect the planet's climate for years, according to the US Geological Survey. When sulfur dioxide is emitted from volcanoes, it blocks sunlight and interacts with the atmosphere, cooling the Earth's surface.

For example, the US Geological Survey explains that a major eruption of the Yellowstone volcano could change global weather patterns and affect agricultural production for an extended period. However, predicting the specific consequences of such a large explosion remains impossible.

The main way a volcanic eruption can affect the weather is by cooling temperatures locally and globally by sending huge clouds of sulfur dioxide into the stratosphere.

The US Geological Survey explained that dust and sulfur dioxide resulting from a large eruption can also lead to vibrant sunsets and sunrises, as the particles scatter light at different wavelengths.
