How about transforming the atmosphere of venus by seeding it with genetically engineered, photosynthetic, airborne bacteria? Perhaps they could survive in the upper, cooler regions of the atmosphere. As they convert carbon dioxide into oxygen and other byproducts, the atmosphere might cool as the greenhouse effect lessens. The bacteria would have to be tiny enough, or have a structure that enables them to capture tiny windcurrents enough, to be kept aloft.
