Seeding the atmosphere with aluminum oxide: A good idea?

Click For Summary

Discussion Overview

The discussion revolves around the proposal of seeding the atmosphere with aluminum oxide as a potential solution to mitigate global warming. Participants explore the implications of this method, including its environmental impact and effectiveness, while considering alternative approaches to addressing climate change.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant suggests that seeding the stratosphere with aluminum oxide could reduce global warming by altering the emissivity of greenhouse gases, allowing heat to be reradiated into space.
  • Another participant expresses skepticism about the reliability of expert recommendations in environmental management, questioning the efficacy of engineering solutions that may have unforeseen consequences.
  • A different viewpoint emphasizes the complexity of environmental issues, arguing that historical human activities have already set significant changes in motion, and that simple solutions may not be adequate.
  • Concerns are raised about the potential health risks associated with aluminum, referencing its association with Alzheimer's disease, and suggesting alternative methods such as painting roofs white to reflect sunlight.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus. There are multiple competing views regarding the viability and safety of using aluminum oxide for atmospheric seeding, as well as differing opinions on the effectiveness of engineering solutions to environmental problems.

Contextual Notes

Participants express uncertainty about the long-term effects of introducing aluminum oxide into the atmosphere and the potential for unintended consequences. The discussion highlights the complexity of environmental interventions and the need for careful consideration of various factors.

Let's assume for the moment that beyond any doubt, global warming is real. Does this offer a viable solution to reduce global warming? Could this create another environmental disaster by loading the biosphere with aluminum oxide [apparently the preferred choice to be used in jet fuel].

A method is disclosed for reducing atmospheric warming due to the greenhouse effect resulting from a greenhouse gases layer. The method comprises the step of seeding the greenhouse gas layer with a quantity of tiny particles of materials characterized by wavelength-dependent emissivity or reflectivity, in that said materials have high emissivities in the visible and far infrared wavelength regions and low emissivity in the near infrared wavelength region. Such materials can include the class of materials known as Welsbach materials. The oxides of metal, e.g., aluminum oxide, are also suitable for the purpose. The greenhouse gases layer typically extends between about seven and thirteen kilometers above the Earth's surface. The seeding of the stratosphere occurs within this layer. The particles suspended in the stratosphere as a result of the seeding provide a mechanism for converting the blackbody radiation emitted by the Earth at near infrared wavelengths into radiation in the visible and far infrared wavelength so that this heat energy may be reradiated out into space, thereby reducing the global warming due to the greenhouse effect.

The details are clearly outlined in U.S.

General comment: if the life expectancies of house plants, tropical fish, terrrarium biota, and the like in the care of "the experts" were a matter of public record, I might be more inclined to take the ideas they propose seriously --- they ain't, I'm not, and my experience has been that life expectancies of plants and fish are inversely proportional to the number of "expert" recommendations implemented in care and feeding of same.

That said, the "engineering" approach to remedies for environmental concerns is not something I'd encourage --- "let's try this, and if it doesn't work, or screws things up worse, we should be able to fix it by adding that stuff over there."
 
Every movement has affect on something. The alteration of a nudge on a wheather pattern created by development over hundreds of years, heat realease do to fossil fuels, removal of trees and other natural growth, the wiping out of great portions of algae in the oceans have all set things in motion. Ever increasing human populations, and the insataible unconcious/conscious expression of greed that consumes the world. It cannot be fixed by a bandaid.
 
Well Aluminium has been associated with http://www.alzheimers.org.uk/Facts_about_dementia/Risk_factors/info_aluminium.htm . So the cure may be worse than the problem. Why not paint all the roofs white. That would help as well.
