  1. Assignment Volcanic eruptions are a good example of a natural climate forcing mechanism. To prepare you for our module capstone project on the possible effects of a modern day catastrophic volcanic eruption, complete Volcanic Eruptions Part A before coming to class on _##/##/## (the day of unit 6)______

  2. A little background on volcanoes

  3. How would a volcanic eruption alter Earth’s mean surface temperature Volcanic eruption ? Earth’s mean surface Temperature Take a minute to jot down your ideas in the space below, compare with your neighbor and revise as appropriate, and then be prepared to share with the class.

  4. How would a volcanic eruption alter Earth’s mean surface temperature Volcanic eruption - Earth’s mean surface Temperature Figure suggests that solar cooling is greater than increased greenhouse trapping.

  5. See 1883 Krakatoa eruption And 1991 Mt Pinatubo Eruption Both indicated by vertical lines

  6. What: Large eruption event Approximately 10 km3 (tephra) 10 Gtonnes magma (~ 5 km3) 17 Mtonnes SO2 (USGS) Eruption: June 12 – 16 , 1991 The abundance of sulfate aerosols created from SO2 and water vapor evolve over time.
