Exploring Volcano-Inspired Technology for Mitigating Global Warming

This article delves into an innovative approach to combat global warming by mimicking the natural cooling effects of volcanic eruptions. It discusses the Haze Effect — a phenomenon where sulfur-rich gases create reflective clouds in the stratosphere, reducing solar radiation and cooling the Earth. The article evaluates potential methods for artificially replicating this effect using simple technology, like large balloons and hoses, while addressing the ethical implications and environmental concerns of such interventions. Readers are encouraged to think critically about our alternatives and the moral dimensions of geoengineering.

  1. Technology to mitigate global warming Mimicking a Volcano

  2. Technology • Doesn’t have to be about new gadgets or phones Can be as simple as an abacus

  3. The idea behind the madness • The Haze Effect • Global cooling after eruptions • Laki • Tambora • Krakatau • Pinatubo

  4. Famous Eruptions • Mt. St. Helens eruption > El Chichon eruption • Mt. St. Helens lowered global temp by 0.1° C • El Chichon lowered global temp 3-5 times that!!!!! WHY??

  5. The Haze Effect • The pyroclastic cloud is not a good measure • Sulfur-rich gases • Sulfur + Water Vapor = dense clouds of sulfuric acid droplets in the stratosphere • Absorb solar radiation and scatter it back to space • Decreases troposphere Temperature

  6. British Experiment • Attempt to create the haze effect without all the damage • Pipe chemicals into the stratosphere • Increase reflection of solar radiation back into space • Items needed: • one balloon the size of a soccer stadium • One 12-mile long garden hose.

  7. Trial Run • Pumping plain water into the air to test if it is possible • If it works: they will pump sulfates and aerosols

  8. Class Discussion • Do we think this will work? • Is this environmentally moral and scientifically ethical? • What are our alternatives? • Are they more possible than this solution?

  9. Pros and Cons of this lesson Highlights • Science talk • Real world issues • Ethics of science • Teach volcano mechanism • Need to know • FOCUS • Provides opportunity to relook at the situation after project is launched Pitfalls • May not be “as cool” as a computer simulation or video or 3Doodle, etc. • Is not a teaching aid technology • Very primitive form of “technology” but has a very advanced task

  10. My opinion • Sometimes gadgets take away from learning rather than amplifying • I chose this article because sometimes it is more advantageous to just talk about new technologies in the field. I think this gets students thinking critically rather than “playing” with a new technology. It has to do with my field of ecology. It is a very important topic and real world problem.
