The cost of geoengineering solutions has been estimated to be

A thought experiment on developing a and maintaining an aircraft fleet to inject dust into the stratosphere. Assuming global cooperation. Assuming that solution works. Assuming you can scale up the dust production without driving up cost. Assuming there are no side effects. Assuming variations in weather don’t trigger war now that there’s someone to blame. Assuming it doesn’t disrupt our food production. Assuming it doesn’t lead to additional extinction events. Assuming -0.3°c over 25 years is enough
