"I used to work at Lawrence Livermore National Lab, and I once participated in a meeting where we all sat around a room and thought about how we could manipulate geophysical systems to use it as a weapon. the meeting was about weaponizing geophysical interventions....could you interfere in Earth functioning in a way that you could use it as a military weapon. Could you change climate? ...what could you do in terms of manipulating Earth's physical systems..."
"...some of the ideas....could we blow up hydrogen bombs underwater offshore that could cause tidal waves that would go over a city? ... you could imagine putting pathogens in a cloud...that would rain down on your enemy...and do chemical or germ warfare in this kind of way..."
