At the moment, I am not in favor of taking any of this research outdoors and experimenting in the real climate. There are few known environmental regulations to govern the kinds of experiments that would take place in the stratosphere. What happens if there are transboundary effects from experimentation? This is something I've looked at with in terms of the US government and the US military in that the United States has far and away the leader on solar geoengineering research.
Solar geoengineering — the idea of cooling the planet by deflecting the sun’s rays — is so risky that scientists and policy experts can’t even agree on whether to research it.
