2) In the future we think volcano geoengineering might become more likely. More renewable energy needs like supercritical geothermal, brine mining for critical metals and Carbon sequestration, will mean drilling closer to volcanic plumbing systems, with potential interactions.

Also, increased research on solar radiation management, means that our our understanding of the stratosphere and how to manipulate it is likely to increase, especially should we want to reverse any stratospheric injections. E.g. 2nd type of volc geoengineering we outline (below)
