Environmental problems are, roughly, of two sorts: concrete, palable, fairly well known, and related primarily to the present; or abstract, unfamiliar, rather badly known, and related primarily to the future. Pollution is mainly of the first sort. Much of it can be seen, smelled, and tasted right now. Given minimal environmental awareness, public pressure is high to lower its incidence and impact. Resource depletion, soil and water depravation and climatic change are of the second sort. Public pressure to diminish the environmental risks associated with these problems cannot be expected from reactions to direct impacts but only from the persistence of a high level of future-oriented environmental concern and an educational and political system supporting it. Environmental politics in regard to problems of the first sort is mainly a matter of enlightened self-interest. Environmental politics in regard to problems of the latter sort is unthinkable without an essentially ethical basis.

Rigorous mapping of climatic patterns outstands as one of the mayor issues concerningclimatic change. This paper investigates the extent of the bioclimatic approach to develop a rigorouscartographic methodology to express climatic diversity patterns. Michoacan, Mexico was chosen torepresent a region of complex geo-ecological layout where the Nearctic and Neotropical biogeographicalrealms converge. Bioclimatic indices were computed and their spatial expression was processed in aGeographic Information System. Ground verification was performed at 93 sites across the province. Inaddition, from 2010 until 2012, more than 2000 kilometers of roads were surveyed to gather data onisobioclimate boundaries. In total, one macrobioclimate, two bioclimate s, four thermotypes, fiveombrotypes and 14 isobioclimates were distinguished in Michoacan. The Tropical pluviseasonal bioclimatewas the predominant bioclimate, covering 56.17% of the province. The Tropical xeric covers 43.82% and theTropical pluvial is practically negligible, covering 0.01% of the entire province. The relevance of theoutcome is discussed in light of its potential use for assessing likely effects of climatic change. ; The National Council of Science and Technology of Mexico (CONACYT) awarded a PhD scholarship tothe first author. Financial, institutional and logisticsupport was provided by UNAM-DGAPA (projectIN202214) as well as by SUMA, former government ofthe Province of Michoacan; and project AECID 2010-2012 ; SI

This article first introduces the correlation between volcanism and global climatic abnormalities (commonly referred to as global cooling), with particular reference to the Tambora eruption in 1815. Recent case studies in China concerning this volcanic effect and climate changes in the nineteenth century are brought in to substantialize and revise some general statements previously made about China. These case studies cover various regions, including the Yangzi Delta, Yunnan, the Jiaodong Peninsula, and the North China Sea area, and examine a wide range of topics such as floods, famines, economic recession, crop patterns (including those of New World crops), and Pacific herring catches. Finally, this article provides suggestions for future studies of the Tambora effects in China and proposes to bring climate into the specific temporal span of the decline of the Qing Empire.

We investigate the role that climatic change has played in the pattern of urbanization in sub-Saharan African countries compared to the rest of the developing world. To this end we assemble a cross-country panel data set that allows us to estimate the determinants of urbanization. The results of our econometric analysis suggest that climatic change, as proxied by rainfall, has acted to change urbanization in sub-Saharan Africa but not elsewhere in the developing world. Moreover, this link has become stronger since decolonization, which is likely due to the often simultaneous lifting of legislation prohibiting the free internal movement of native Africans.

Climate change is now a hot political topic that blurs the boundary between policy relevant and policy prescriptive (as contained for example in the avowed stance of the Intergovernmental Panel on Climate Change). The growing political relevance of climate change science necessarily places a premium on timely advice and on risk assessment and management. What is the role of climate scientists in that new situation?
