Overview

The Ethics of Cooling the Planet through Geo-Engineering, a three part series.

Part I: Will Aerosol Particles Prevent Global Warming?

 

A recent report of the National Academy of Sciences finds that, “A strong, credible body of scientific evidence shows that climate change is occurring, it is caused largely by human activities, and poses significant risks for a broad range of human and natural systems.” The average Earth temperature has already risen 1.4° F since pre-industrial times and, if climate change is not abated, it is expected to rise an additional 2 to 11.5 º F this century. Fears of the possible catastrophic consequences of such a rise have lead some people to propose that we prepare to intentionally cool the planet, not by reducing greenhouse gas emissions, but by geo-engineering schemes, such as seeding the oceans with carbon chomping algae and releasing sun blocking aerosols into the atmosphere.

Geo-engineering proposals such as these raise many ethical questions:

  • What would the side-effects be?
  • How much do we know?
  • Does pursuing this sort of research distract expertise and money away from projects to reduce greenhouse gas emissions?
  • Who has the right to intentionally alter the Earth’s climate?
  • Is a workable system of cooperative international governance for geo-engineering possible or would geo-engineering lead to international conflict?
