摘要: The impression gained by visitors to the New Guinea Highlands is of an equable climate year round with its usual, though not invariable, daily Pattern warm sunshine in mornings regularly followed rainfalls afternoons. Yet according Wola people Southern Province, their region sometimes experiences weather so inclement that food shortages occur, even famine extreme conditions. threat climatic perturbations has recently attracted popular Western interest (Houghton et al. 1990). possible environmental consequences our industrial pollution atmosphere are causing concern: so-called greenhouse effect (Slade 1990; Heymsfield and Miloshevich 1991; Vellinga Swart 1991), global warming (Maddox Hecht Schneider 1990), acid rain (Pearce Mason mention but three topical issues. While these concerns may well affect highland patterns, they do currently concern living there, unlike inhabitants some low-lying islands Pacific who fear catastrophic loss land if sea levels rise as forecast. Major usual pattern however, which say have occurred for generations, always been a worry. THE WOLA AND THEIR CLIMATE speakers occupy five valleys Papua Guinea, from Mendi River east Ak west.
