while idea of injecting sulfates into atmosphere does not sound promissing, idea of not doing any geoengineering and trying to just keep the current climate is even worse, because huge portion of the earth is inhabitable now. And there are many alternative methods, more controllable methods for geoengineering. A particularly interesting one that doesn't get enough attention is usage of solar updraft towers. If towers are sufficiently high and numerous, they can carry up dust and small particles from the surface, inducing formation of clouds, they can improve convection in the atmosphere, acting similar to mountains. Over the sea they can prevent huricanes by reducing the temperature gradient. And a chain of them would help to bring more moist air from shore to the desert regions inland.
