The starting point for this article is the excellent article by Professor Marglin on the dangers of climate change. He outlines a broad remedial prescription, a new economics based on ecological concerns and a broadly based cultural revolution to change people’s thinking. We agree with Marglin that the prevailing neoclassical analysis is fundamentally flawed because inter alia it adheres to individuals’ independent (rather than inter-dependent) utility functions. It is argued that ultimately the problem of the ecosystem, and indeed violent threats of mass destruction that we constantly face cannot be solved without the insights that community and spiritual thinking bring us.

This paper suggests that certain conceptual, ethical and economic issues surrounding genetics are also relevant to the challenges that climate change poses to the humanities. It takes J.H. Prynne's and Derrida's engagements with biology and information theory as a starting point to address climate modelling, emissions management, biofuels, bioengineering and the importance of scientific competence.

The production of bioenergy and biofertilizers based on animal and plant biomass is a crucial pillar in circular economy (CE). CE conceptual model and main aims are closely related to the 3 “R” (reduce, reuse, and recycle) rule, which is to improve the use of resources, minimize waste, and assure sustainability. Although bioenergy offers many opportunities and could be an alternative to fossil fuels use, the path for a broader implementation of this type of activity is still long. This study marks the starting point or direction of research to be taken, ensuring the existence of benefits from plant and animal biomass for the production of bioenergy and biofertilizer, as well as the contributions of this type of production to the circular economy and the mitigation of the climate change impacts.

In our final hour (2003), cambridge university astronomer Martin Rees concluded that the odds of global civilization surviving to the year 2100 are no better than one in two. His assessment of threats to humankind ranging from climate change to a collision of Earth with an asteroid received good reviews in the science press, but not a peep from any political leader and scant notice from the media. Compare that nonresponse to a hypothetical story reporting, say, that the president had had an affair. The blow-dried electronic pundits, along with politicians of all kinds, would have spared no effort to expose and analyze the situation down to parts per million. But Rees’s was only one of many credible and well-documented warnings from scientists going back decades, including the Fourth Assessment Report from the Intergovernmental Panel on Climate Change (2007). All were greeted with varying levels of denial, indifference, and misinterpretation, or were simply ignored altogether. It is said to be a crime to cause panic in a crowded theater by yelling “fire” without cause, but is it less criminal not to warn people when the theater is indeed burning? My starting point is the oddly tepid response by U.S. leaders at virtually all levels to global warming, more accurately described as “global destabilization.” I will be as optimistic as a careful reading of the evidence permits and assume that leaders will rouse themselves to act in time to stabilize and then reduce concentrations of greenhouse gases below the level at which we lose control of the climate altogether by the effects of what scientists call “positive carbon cycle feedbacks.” Even so, with a warming approaching or above 2°C we will not escape severe social, economic, and political trauma. In an e-mail to the author on November 19, 2007, ecologist and founder of the Woods Hole Research Center George Woodwell puts it this way: . . . There is an unfortunate fiction abroad that if we can hold the temperature rise to 2 or 3 degrees C we can accommodate the changes. The proposition is the worst of wishful thinking.

Climate change is expected to affect crop production worldwide, particularly in rain-fed agricultural regions. It is still unknown how irrigation water needs will change in a warmer planet and where freshwater will be locally available to expand irrigation without depleting freshwater resources. Here, we identify the rain-fed cropping systems that hold the greatest potential for investment in irrigation expansion because water will likely be available to suffice irrigation water demand. Using projections of renewable water availability and irrigation water demand under warming scenarios, we identify target regions where irrigation expansion may sustain crop production under climate change. Our results also show that global rain-fed croplands hold significant potential for sustainable irrigation expansion and that different irrigation strategies have different irrigation expansion potentials. Under a 3 °C warming, we find that a soft-path irrigation expansion with small monthly water storage and deficit irrigation has the potential to expand irrigated land by 70 million hectares and feed 300 million more people globally. We also find that a hard-path irrigation expansion with large annual water storage can sustainably expand irrigation up to 350 million hectares, while producing food for 1.4 billion more people globally. By identifying where irrigation can be expanded under a warmer climate, this work may serve as a starting point for investigating socioeconomic factors of irrigation expansion and may guide future research and resources toward those agricultural communities and water management institutions that will most need to adapt to climate change.

Mountain communities are adapting their livelihoods to a complex combination of social, political and economic changes and associated risks. Despite recognition of adaption in response to multiple changes in sustainable livelihood and critical climate change literature, risks attributed to biophysical effects of climate change have increasingly assumed importance. Consequently, diversification is promoted as an adaptive approach to reduce such risks. However, understanding livelihood adaptation from the vantage point of climate change alone might lead to a limited understanding of non-climatic factors also shaping it. This paper proposes understanding adaptation through analysing long-term livelihood changes and using society rather than climate change as a conceptual starting point. It argues that such an approach has better potential to highlight a broader range of dynamic drivers operating over decades and to inform contextually grounded rural livelihood adaptation policies. Changes are traced in the overall livelihood trajectories among four rural communities in Nepal, in living memory, to understand the role of adaptation in shaping it. Qualitative life narratives were collected and complemented by key informant interviews, field observations and the analysis of official documents. The findings suggest that livelihoods have shifted not only from subsistence towards income generation but also from engagement in diverse livelihood sectors towards specialisation; the opposite of the advocated diversification. The role of political, economic, social and cultural processes within and outside the community has been prominent in shaping this trajectory.

This article includes literature (principally fiction, but also poetry, spoken drama, opera, and popular performances), cultural policy and debate, and the history of the Communist Party’s relations with cultural intellectuals for the years 1942–1976. The starting point is Communist Party chairman Mao Zedong’s “Talks at the Yan’an Forum on Literature and Art,” delivered in May 1942, when China was politically divided and at war with Japan, and the period ends with Mao’s death in September 1976, an event closely followed by the arrest of his widow and her closest associates in a coup the following month. Mao’s “Talks” set the tone for the entire period, demanding the subordination of the arts to the Party’s mission as currently defined, and insisting that culture serve the Party’s constituency of “workers, peasants, and soldiers.” The “Talks,” variously interpreted, remained Party policy through the civil war period (1945–1949), and following the establishment of the People’s Republic in 1949. The new communist state established a Soviet Union–style cultural bureaucracy, and the most fortunate writers, performers, and artists were rewarded with official recognition and state sponsorship; also imported from the Soviet Union was the doctrine of socialist realism, with its requirement for loyalist and heroic works celebrating the nation’s prospective progress along the road to the glorious future of communism. Throughout the Mao era, the authorities sought to sponsor a new socialist Chinese culture, with varying degrees of tolerance for indigenous traditions and Western influence. The Communist Party and its leader believed in the power of the arts to support, and in the wrong hands to undermine, the cause of socialism; Mao intervened periodically in cultural matters, and many of the political campaigns that disrupted the period had cultural components. The effect of mercurial and often vindictive policy changes on writers and artists could be devastating: the Anti-Rightist campaign of the late 1950s and the Cultural Revolution of Mao’s last decade (1966–1976) saw the persecution of many of the nation’s leading cultural figures; virtually no writer or artist had an uninterrupted career. Chinese cultural histories customarily view the Yan’an and civil war period as distinct, and they divide the period from 1949 to 1976 into the seventeen years before 1966 and the Cultural Revolution decade that followed. Although this periodization overstates the discontinuity of cultural policy and artistic output, it will be observed for convenience here. A note on Romanization: English-language publications from China prior to 1979 use a modified, and inefficient, version of the now little-used Wade-Giles Romanization; after 1979, Chinese publishers converted to the now conventional pinyin Romanization. For Western scholarship or translations, the transition from Wade-Giles (in its more precise form) to pinyin took place at around the same time.

Abstract Permafrost and glaciers are being degraded by the warming effects of climate change. The impact that this degradation has on slope stability in mountainous terrain is the subject of ongoing research efforts. The relatively new availability of high-resolution (≤ 10 m) imagery with worldwide coverage and short (≤ 30 days) repeat acquisition times, as well as the emerging field of environmental seismology, presents opportunities for making remote, systematic observations of landslides in cryospheric mountainous terrain. I reviewed the literature and evaluated landslide activity in existing imagery to select five ~ 5000-km2 sites where long-term, systematic observations could take place. The five proposed sites are the northern and eastern flanks of the Northern Patagonia Ice Field, the Western European Alps, the eastern Karakoram Range in the Himalayan Mountains, the Southern Alps of New Zealand, and the Fairweather Range in Southeast Alaska. Systematic observations of landslide occurrence, triggers, size, and travel distance at these sites, especially if coupled with observations from in situ instrumental monitoring, could lead to a better understanding of changes in slope stability induced by climate change. The suggested sites are not meant to be absolute and unalterable. Rather, they are intended as a starting point and discussion starter for new work in this expanding landslide research frontier.

Abstract. This paper explores the potential for assessing the impacts of climate change upon flood frequency for the gauged, upland Wye catchment at Plynlimon, Wales, UK, while taking account of uncertainty in modelling rainfall-runoff processes under current conditions. A continuous simulation methodology which uses a stochastic rainfall model to drive the rainfall-runoff model TOPMODEL is utilised. Behavioural parameter sets for both the rainfall model and TOPMODEL are identified prior to the climate change runs using the Generalised Likelihood Uncertainty Estimation (GLUE) methodology. The "medium-high" UKCIP98 climate change scenario, obtained from the HadCM2 GCM simulations, is used as a starting point for a variety of different scenarios at the catchment scale. It is demonstrated that while the scenarios have only a small impact upon the likelihood weighted flood frequency uncertainty bounds in comparison with the current condition scenario, the risk of a given discharge as an element in the distribution of T year floods is changed. This underlines the need to account explicitly for uncertainty within hydrological modelling, especially in estimating the impacts of climate change.

Climate change is modifying disturbance regimes, affecting the severity and occurrence of extreme events. Current experiments investigating extreme events have a large diversity of experimental approaches and key aspects such as the interaction with other disturbances, the timing, and long-term effects are not usually incorporated in a standardized way. This lack of comparability among studies limits advances in this field of research. This study presents a framework that is comprised of two experimental approaches designed to test expected changes on disturbance regime due to climate change. These approaches test the effects of disturbances becoming more clustered and more extreme. They use common descriptor variables regardless of the type of disturbance and ecosystem. This framework is completed with a compilation of procedures that increase the realism of experiments in the aforementioned key aspects. The proposed framework favours comparability among studies and increases our understanding of extreme events. Examples to implement this framework are given using rocky shores as a case study. Far from being perfect, the purpose of this framework is to act as a starting point that triggers the comparability and refinement of these types of experiments needed to advance our understanding of the ecological effects of extreme events.
