Thanks for the information. I have read the article and applaud.
I wonder why the authors did not consider local isolated tests of the sulfur approach. As I recall the 0.5 C drop following the volcanic eruption was worldwide and lasted one to two years. It took time for the sulfur to spread. Why not a local, immediate, short term experiment before the sulfur has had ti me to spread significantly? It would give an idea of possible greater magnitude but with reduced risk except locally. It would avoid other effects from a volcanic eruption. -gene ----- Original Message ----- From: "Geoengineering Our Climate (eds.

Below is an excerpt from the introduction (in lieu of an abstract): " ...How then can geoengineering be studied? One obvious technique is to use global climate models (“indoor” research) to simulate various proposed geoengineering schemes, such as adding aerosols to the stratosphere to reflect incoming sunlight or adding sea salt to marine stratus clouds to brighten them. Since these two techniques mimic volcanic eruptions and ship tracks, another suggestion is to study those phenomena as analogs to geoengineering. There have also been several suggestions for field experiments, as well as some small scale tests (“outdoor” research), to learn about geoengineering. In this article, we review these different research methods, commenting on their utility, safety, ethics, and governance. We also discuss natural analogs for geoengineering, such as the 1991 eruption of Mt. Pinatubo and the observation of ship tracks, highlighting both their utility in learning about the effects of geoengineering and their limits in providing knowledge. As we will demonstrate, geoengineering research is inseparable from climate research."
