In recent decades, the impacts of climate on society and on human well-being have attracted increasing amounts of attention, and the forecasts that predict such impacts have become more accurate. Forecasts are now distributed and used more widely than they were in the past. This article reviews three cases of such use of forecasts in Latin America. It shows that in all cases, the users are concentrated in particular sectors and regions (agriculture in the Argentine pampas, fisheries on the Peruvian coast, water resources in northeastern Brazil) and that the forecasts are distributed not by government agencies but by intermediate organizations—semistatal organizations or nongovernmental organizations. It draws on the concept of environmental citizenship to discuss these cases and assesses them for such attributes of citizenship as equity, transparency, accountability, and promotion of collective goals. It traces the implications of these cases for the current era of global warming.
