Abstract	Se presentan evidencias geomorfologicas y palinologicas indicadoras de paleoescenarios existentes en los ultimos dos millones de anos en el extremo sur de Patagonia y Tierra del Fuego. Estos procesos indican la ocurrencia de cambios climaticos no forzados por intervencion humana en la atmosfera. Los periodos frios habrian sido progresivamente menos intensos desde la Gran Glaciacion Patagonica, ocurrida hace 1 millon de anos. Durante el Holoceno y los tiempos historicos, las glaciaciones se restringieron a las zonas superiores a los 900 m s.n.m. y el deterioro climatico no habria afectado significativamente al ecosistema bosque ubicado a menos de 400 m s.n.m. Un importante periodo calido ocurrido en tiempos historicos fue registrado en las zonas de altura en Patagonia Norte y en las cercanias al nivel del mar en Tierra del Fuego
