The climate change we have right now has been caused by geoengineering too -- accidental geoengineering.

Intentional, careful geoengineering is the only real chance we have of holding back climate change. Human societies simply will not be willing to make the sacrifices necessary to roll back climate change solely by reducing emissions.

A combination of politically acceptable emission cuts, geoengineering, and acceptance of/adaptation to higher temperatures and their consequences is the only possible outcome in the real world. So hold back on the knee-jerk reactions to geoengineering and take it seriously.
