What I have said is that your assertion that some unspecified geoengineering scheme or schemes «CAN» — and that was your word, «CAN», not «conceivably might» or «possibly could», but «CAN» — control the Earth's temperature as accurately and reliably as a simple elecromechanical on / off thermostat controls a furnace, has no evidence whatsoever to back it up.

An early, comprehensive and transparent governance structure — in which the concerns of developing nations, for example, could find expression — would serve to temper any rush into insufficiently proven geoengineering schemes and act as a counterweight to the pro-geoengineering constituency that is already taking shape (15, 18, 19).
