Actually, land management probably should be taken into account by regional authorities. Reforestation around Kilimejaro (sp?) would reestablish the snow cap up there fairly quickly. Reestablishment of the swamps over 60 percent of Florida will cool the state by "several" degrees and increase rainfall by 10 - 12% according to the Matthews et al study. Similar opportunities exist in western Africa, Australia and no doubt many other places. Should the planet continue to warm, regardless of the cause, land use may well be a part of adaptation necessary to maintain local temperature and precipitation.
