The history and origin of the experiment idea arosed from tje SPICE the event: a volcano eruption and its climate cooling effect 3. Some assessment by experts a. questions: which substance would be the best. how much should be used and when... still need to be tested b. the process of the effect c. HH:"most cost-effective method" d. criticize: still unsure about the actual effect and how it works. and some harmfulness e. JB: But it doesn't violate the international agreement on atmosphere 4.
