Aerosol Aerosol: suspension of tiny particles in the air
Aerosol: Direct Effect and Indirect Effect Direct Effect: aerosol in Earth’s stratosphere reflects sunlight away from Earth. ,[object Object],[object Object]
Experimental Results 1982 El ChichonEruption: 7 million metric tons of SO2 caused global cooling of 0.3°C. 1991 Pinatubo Eruption: 20 million metric tons of SO2 caused global cooling of 0.5°C 1815 TamboraEruption: Largest eruption in recorded history released unknown amount of SO2. Global Cooling of about 3°C. Data from U.S Geological Survey
Methods of Climate Engineering Send aerosol into earth’s atmosphere using balloons, artilleries, or airplanes.

Global cooling using aerosol

  • 2. Global Warming Global Warming: the gradual increase in the average global temperature.
  • 3. Global Warming vs. Cooling From IPCC (Intergovernmental Panel on Climate Change) Report
  • 4. Aerosol Aerosol: suspension of tiny particles in the air
  • 5.
  • 6. Experimental Results 1982 El ChichonEruption: 7 million metric tons of SO2 caused global cooling of 0.3°C. 1991 Pinatubo Eruption: 20 million metric tons of SO2 caused global cooling of 0.5°C 1815 TamboraEruption: Largest eruption in recorded history released unknown amount of SO2. Global Cooling of about 3°C. Data from U.S Geological Survey
  • 7. Methods of Climate Engineering Send aerosol into earth’s atmosphere using balloons, artilleries, or airplanes.
