Discussion Overview

The discussion revolves around the feasibility of installing a sunshade in the upper atmosphere to mitigate drought and heat on Earth. Participants explore theoretical implications, potential designs, and alternative solutions to environmental challenges.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Nancy proposes the idea of a sunshade in the upper atmosphere that could shade areas affected by drought, questioning its structural integrity and feasibility.
  • Another participant challenges the effectiveness of reduced sunlight in addressing water scarcity, suggesting alternative solutions like pipelines from desalination plants.
  • Nancy speculates that reducing heat might eventually lead to rainfall, although she acknowledges the idea may seem unrealistic.
  • A participant mentions that current theoretical applications of sunshades are primarily focused on combating global warming, with suggestions for their placement at the poles to prevent ice melting.
  • Nancy shares information about a study by Ph.D. Roger Angel on the feasibility and logistics of implementing such a sunshade.

Areas of Agreement / Disagreement

Participants express differing views on the practicality and effectiveness of a sunshade for addressing drought and heat, with no consensus reached on the viability of the proposed solution.

Contextual Notes

Discussions include assumptions about the relationship between sunlight, heat, and rainfall, as well as the structural challenges of maintaining a sunshade in the atmosphere. The feasibility study mentioned may have limitations based on current technological capabilities and environmental impacts.

I am wondering if it would be possible to install a sunshade in the upper atmosphere which would move along with the Earth and shade parts of the Earth which are being affected by drought. If a sheet, 100 ft square were unfolded 30 or so miles up would it crumple? stay there? Is this comic book thinking or could it be possible?

How will less sunlight remedy a lack of water? (Why not a pipeline from a desalination plant?)
 
I'm assuming that too much sun equals too much heat and if it cools down maybe, in time, it might rain. Or at least the Earth will stop baking in the heat. As I said, this might be comic book thinking.

The only theoretical use of sun shades as of now, are for global warming purposes. I believe sciencitist have already purpose possible putting sun shades at the poles, to help keep them from melting.
