The Relationship

Variations in environmental parameters (e.g. temperature) that form part of global climate change have been associated with shifts in the timing of seasonal events for a broad range of organisms. Most studies evaluating such phenological shifts of individual taxa have focused on a limited number of locations, making it difficult to assess how such shifts vary regionally across a species range. Here, by using 1445 records of the date of first nesting for loggerhead sea turtles ( Caretta caretta ) at different breeding sites, on different continents and in different years across a broad latitudinal range (25–39° ′N), we demonstrate that the gradient of the relationship between temperature and the date of first breeding is steeper at higher latitudes, i.e. the phenological responses to temperature appear strongest at the poleward range limit. These findings support the hypothesis that biological changes in response to climate change will be most acute at the poleward range limits and are in accordance with the predictions of MacArthur's hypothesis that poleward range limit for species range is environmentally limited. Our findings imply that the poleward populations of loggerheads are more sensitive to climate variations and thus they might display the impacts of climate change sooner and more prominently.

The Relationship

What kinds of issues does the global crisis of climate change present to aesthetics, and how will they challenge the field to respond? This paper argues that a new research agenda is needed for aesthetics with respect to global climate change (GCC) and outlines a set of foundational issues which are especially pressing: (1) attention to environments that have been neglected by philosophers, for example, the cryosphere and aerosphere; (2) negative aesthetics of environment, in order to grasp aesthetic experiences, meanings, and dis/values in light of the catastrophic effects of GCC; (3) bringing intergenerational thinking into aesthetics through concepts of temporality and ‘future aesthetics’ (4) understanding the relationship between aesthetic and ethical values as they arise in regard to GCC.

Temperature is often used to infer how climate influences wildlife distributions; yet, other parameters also contribute, separately and combined, with effects varying across geographical scales. Here, we used an unoccupied aircraft system to explore how environmental parameters affect the regional distribution of the terrestrial and marine breeding habitats of threatened loggerhead sea turtles (Caretta caretta). Surveys spanned four years and ~620 km coastline of western Greece, encompassing low (<10 nests/km) to high (100–500 nests/km) density nesting areas. We recorded 2395 tracks left by turtles on beaches and 1928 turtles occupying waters adjacent to these beaches. Variation in beach track and inwater turtle densities was explained by temperature, offshore prevailing wind, and physical marine and terrestrial factors combined. The highest beach-track densities (400 tracks/km) occurred on beaches with steep slopes and higher sand temperatures, sheltered from prevailing offshore winds. The highest inwater turtle densities (270 turtles/km) occurred over submerged sandbanks, with warmer sea temperatures associated with offshore wind. Most turtles (90%) occurred over nearshore submerged sandbanks within 10 km of beaches supporting the highest track densities, showing the strong linkage between optimal marine and terrestrial environments for breeding. Our findings demonstrate the utility of UASs in surveying marine megafauna and environmental data at large scales and the importance of integrating multiple factors in climate change models to predict species distributions.

Recent years, the studies on global climate change, local traditional knowledge (TK) – especially traditional ecological knowledge (TEK) have attracted a lot of attention. Local traditional knowledge can reflect the ethnic groups’ specific understandings of climate change and its impact. However, studies on the relationship between traditional knowledge and climate change have not achieved such significant result thus far. This paper examines the perspectives, knowledge, and classification of climate change based on local Tibetan traditional knowledge in Deqin County of Yunnan, China. It analyses the local actions how to “cope with” climate change, and further discusses the relationship between traditional knowledge and ecological environment. The suggestion to establish the database of climate change, then, there will be a new system if the database can be connected with TK database. From the new system, we can analyze and choose the appropriate farming practices and “climate-ready” crops to respond to different predicted weather.

The Relationship

This paper considers the challenge to global social policy posed by global climate change. It sets side by side global social policies and global climate change policies, and surveys the governance of each. The first part summarises global social policy in recent years, distinguishing (1) the policies and practices pursued in the global arena, and (2) the structures of global governance and the role of significant global actors. The second part repeats this at a greater length for global climate change. The third part then considers the relationship between these two sets of policies/practices and governance structures, in particular the potential conflicts between the pursuit of social justice and environmental sustainability. It identifies two possible responses – compensation and co-benefits – and maps these onto current global actors, before concluding with a radical vision of eco-social policy.

The Relationship

Knowledge of the relationship between climate change and resource conflict is paramount in resolving resource conflict between farmers and herdsmen in Nigeria. However, there is yet no general agreement on how climate change causes or influences resource conflict. Thus, a review of existing literature that link climate change and resource conflict was conducted for identification of the missing link. These were achieved through the review of literature published in the era of the recent global climate change from late 90s to date. Selections of papers were based on the topic and date of publication. Result showed that there is general agreement that climate change influence resource conflicts. Some of the authors agreed that climate change cannot cause resource conflict in isolation but through influences on other factors that affect resource availability, accessibility and utility. These factors are also influenced by policies and socio-cultural system. Thus, resource conflict may be a secondary or tertiary effect of climate change. Climate change solution is scares in literature that linked climate change and resource conflict. Thus, future studies should be focused on climate change solution to resource conflict.

Theoretical Foundations

One of the main challenges of the future is the strengthening impact of environmental factors on economic development, in particular, environmental threats, climate change, waste minimization and reduction of СО2 emissions. At the present stage, achieving sustainable economic development has become an important item on the global agenda. The purpose of this article is to develop the theoretical foundations of the process of greening in the economy and substantiate practical approaches in Ukraine to overcome global climate challenges. To achieve this goal, the author used retrospective research methods, and abstract-logical, economic-statistical and systematic approaches. Based on the analysis of scientific works of foreign and domestic scientists, the article deepens the theoretical foundations of the concept of greening. In particular, it is established that this concept characterizes the improvement of environmental parameters of production through the introduction of technological, organizational and managerial innovations that increase the efficiency of natural resources, reduce man-made impact improve the quality of the environment and increase the level of environmental education and environmental culture of the population and industrial staff. The results of the study showed that in modern conditions the concept of sustainable dependence of the economy on environmental factors has been formed, which is supplemented by the problem of solving global challenges of mankind. This requires the introduction of new economic approaches to addressing the global challenges posed by climate change, among which the introduction of the principles of circular economy is important.

The Relationship

Global climate change and the expected increase in temperature are altering the relationship between geography and grapevine (V. vinifera) varietal performance, and the implications of which are yet to be fully understood. We investigated berry phenology and biochemistry of 30 cultivars, 20 red and 10 white, across three seasons (2017–2019) in response to a consistent average temperature difference of 1.5°C during the growing season between two experimental sites. The experiments were conducted at Ramat Negev (RN) and Ramon (MR) vineyards, located in the Negev desert, Israel. A significant interaction between vineyard location, season, and variety affected phenology and berry indices. The warmer RN site was generally associated with an advanced phenological course for the white cultivars, which reached harvest up to 2 weeks earlier than at the MR site. The white cultivars also showed stronger correlation between non-consecutive phenological stages than did the red ones. In contrast, harvest time of red cultivars considerably varied according to seasons and sites. Warmer conditions extended fruit developmental phases, causing berry shriveling and cluster collapse in a few cultivars such as Pinot Noir, Ruby Cabernet, and Tempranillo. Analyses of organic acid content suggested differences between red and white cultivars in the content of malate, tartrate, and citrate in response to the temperature difference between sites. However, generally, cultivars at lower temperatures exhibited lower concentrations of pulp organic acids at véraison, but acid degradation until harvest was reduced, compared to the significant pace of acid decline at the warmer site. Sugars showed the greatest differences between sites in both white and red berries at véraison, but differences were seasonal dependent. At harvest, cultivars of both groups exhibited significant variation in hexose/sucrose ratio, and the averages of which varied from 1.6 to 2.9. Hexose/sucrose ratio was significantly higher among the red cultivars at the warmer RN, while this tendency was very slight among white cultivars. White cultivars seem to harbor a considerable degree of resilience due to a combination of earlier and shorter ripening phase, which avoids most of the summer heat. Taken together, our study demonstrates that the extensive genetic capacity of V. vinifera bears significant potential and plasticity to withstand the temperature increase associated with climate change.
