How do volcanoes affect climate change?

How do volcanoes affect climate change?

Volcanoes can influence climate change by releasing ash and gases like sulfur dioxide into the atmosphere, which can cool the Earth.

Can you explain how volcanic eruptions lead to cooling?

Sure! When a volcano erupts, it releases ash and sulfur dioxide, which form sulfate aerosols in the atmosphere. These reflect sunlight away from the Earth, leading to temporary cooling.

Are there any long-term effects of volcanic eruptions on climate?

Yes, while the immediate effects are often cooling, long-term eruptions can contribute to greenhouse gas emissions, potentially leading to warming over time.

How often do significant volcanic eruptions occur?

Significant eruptions happen roughly every few years, but their impact on climate can vary widely depending on the eruption's size and duration.

What are some examples of major eruptions that affected climate?

Notable examples include the 1815 eruption of Mount Tambora, which caused the 'Year Without a Summer' in 1816 due to its global cooling effects.
