  6. Pristine Atmosphere Layer of fine droplets following the Pinatubo eruption

  7. Volcanic Contribution to Climate Change Step 1 Ash and gas enter the atmosphere

  8. Volcanic Contribution to Climate Change Step 2 Ash and gas spread throughout the atmosphere. Eventually, the Earth is wrapped in a layer of ash and gas. Ash and gas plume from Mt. Etna, in northeastern Sicily.

  9. Volcanic Contribution to Climate Change Step 3 Ash and gas block energy from the Sun. Earth's temperature drops.

  10. Volcanic Contribution to Climate Change Step 4 Heat radiating off the surface of Earth becomes trapped in the layer formed by the eruption. Trapped heat changes global climate patterns.

  11. Krakatau Sunsets 1883-85 Krakatau 1883 El Chichon 1982
