This chapter provides a general overview of the effects of climate change on the terrestrial ecosystem and is meant to set the stage for the specific papers. The discussion in this chapter focuses basically on the effects of climatic disturbances on terrestrial flora and fauna, including increasing global temperature and changing climatic patterns of terrestrial areas of the globe. Basically, climate disturbances derived increasing temperature and greenhouse gases have the ability to induce this phenomenon. Greenhouse gases are emitted by a number of sources in the atmosphere such as urbanization, industrialization, transportation, and population growth, so these contributing factors and its effects on climatic events like temperature rise, change precipitation pattern, extreme weather events, survival and shifting of biodiversity, seasonal disturbances, and effects on glaciers are relatively described in this chapter.

Change Impact

Climate change is real, and we, humans, are responsible for it. Its impact is already evident, both on the Earth system (global warming, sea-level rise, sea-ice melting, more intense and frequent extreme weather events such as heat waves and fires) and on people (famines, health issues, migrations, political tensions and conflicts). We need immediate and concrete mitigation actions aiming to reduce greenhouse gases emissions, and adaptation actions to be able to cope with the increasing changing climate. We have to reach zero-net greenhouse gases emissions as soon as possible, by reducing emissions by at least 5% a year, starting from now. Otherwise the climate change impact will become more and more severe: it will induce more injustice, and it will have a major impact on people health. We have the resources and the technologies to deal with it: we must have the courage to change and transform and deal with it. Addressing climate change is not impossible: to the contrary, it is a ‘possible mission’.

New Situation

This paper focuses on cultural analysis and how people are coping with new situation created by climate change in production of millet. Changes relating to climate change are observed; perceived and understood on a local level. This is an important area of study for anthropologists and it is interest of climate scientists as well. This paper is based on anthropological analysis on climate change effects on finger millet production in Argal VDC of Baglung district, West of Nepal. Millet is a staple food of people of Argal and most of Hill people of Nepal. Millet is not only staple food and associated with nutrition of people. It's also associated with rituals during production and as well as during consumption. Increasing temperature, changing rainfall patterns, extreme weather events are linked with climate change which has direct effect on life of all people but also millet production and ritual activities.

Ethical Communication

ABSTRACTRecent records of increasing temperature, melting of sea-ice, retreating glaciers, thawing permafrost, increasing sea levels, and increase in the frequency and intensity of extreme weather events provide clear evidence of global climate change, particularly in the Arctic. The impacts of climate change are not only environmental, but also influence social, economic, psychological, and political conditions in the region. The confluence of these conditions emphasises the need for improved communication of climate information and formulation of ethical responses to address changes in the Arctic. This review explores the meaning of ethical communication followed by an overview of the barriers to ethical communication including uncertainties related to climate change, and constructions of varying interpretations of climate change due to discipline-specific perspectives of science, journalism, and law, in the Arctic. The final section of this paper summarises key elements of ethical communication, and integration of ethical principles in formulating decision-making strategies to address climate change in the Arctic.

General Concern

Most scenarios indicate that people in developing countries are more vulnerable and less capable of adapting to climate change. Since our public understanding of risk toward climate change in developing countries is limited, this article presents results from Costa Rica and Nicaragua, two countries which are socio-economically distinct, but which are expected to suffer similar extreme weather events. From October of 2008 until May 2010, a total of 1,047 respondents were surveyed in cities of both countries. The main results indicate that climate change is a widely known concept but other notions such as “carbon footprint” are foreign to most respondents. Despite the general concern with its negative consequences, respondents’ foremost concern is linked to their socioeconomic situation, and how it will be impacted by climate change in such aspects as poverty and social security. The results presented here contribute to advance national and international policies aiming to support mitigation or adaptation strategies in developing countries.

Document Review

This article addresses three research questions: How does climate change impact food production? What are the governance challenges associated with managing such impacts? What are the conditions for future success in managing the impacts of climate change on food production? To answer these questions, the researcher undertook a document review and analysis to address these various aspects with a major focus on East Africa. The study finds that climate change affects food production largely through its physical impacts on precipitation and increased the frequency of extreme weather events. Within a context of weak governance; climate change further challenges governance institutional structures and mechanisms. The study concludes that specific aspects of the prevailing climate change governance regime require major reforms (particularly the role of the state, corporations and civil society) while other climate governance mechanisms need to be completely overhauled (for example through establishment of a new World Environment Organization).

Ecosystem Resilience

AbstractGlobal climate change likely alters the structure and function of vegetation and the stability of terrestrial ecosystems. It is therefore important to assess the factors controlling ecosystem resilience from local to global scales. Here we assess terrestrial vegetation resilience over the past 35 years using early warning indicators calculated from normalized difference vegetation index data. On a local scale we find that climate change reduced the resilience of ecosystems in 64.5% of the global terrestrial vegetated area. Temperature had a greater influence on vegetation resilience than precipitation, while climate mean state had a greater influence than climate variability. However, there is no evidence for decreased ecological resilience on larger scales. Instead, climate warming increased spatial asynchrony of vegetation which buffered the global-scale impacts on resilience. We suggest that the response of terrestrial ecosystem resilience to global climate change is scale-dependent and influenced by spatial asynchrony on the global scale.

<p>Terrestrial ecosystems are intimately linked with the global climate system, but their response to ongoing and future anthropogenic climate change remains poorly understood. Reconstructing the response of terrestrial ecosystem processes over past periods of rapid and substantial climate change can serve as a tool to better constrain the sensitivity in the ecosystem-climate response.</p><p>In this talk, we will present a new reconstruction of soil respiration in the temperate region of Western Europe based on speleothem carbon isotopes (δ<sup>13</sup>C). Soil respiration remains poorly constrained over past climatic transitions, but is critical for understanding the global carbon cycle and its response to ongoing anthropogenic warming. Our study builds upon two decades of speleothem research in Western Europe, which has shown clear correlation between δ<sup>13</sup>C and regional temperature reconstructions during the last glacial and the deglaciation, with exceptional regional coherency in timing, amplitude, and absolute δ<sup>13</sup>C variation. By combining innovative multi-proxy geochemical analysis (δ<sup>13</sup>C, Ca isotopes, and radiocarbon) on three speleothems from Northern Spain, and quantitative forward modelling of processes in soil, karst, and cave, we show how deglacial variability in speleothem δ<sup>13</sup>C is best explained by increasing soil respiration. Our study is the first to quantify and remove the effects of prior calcite precipitation (PCP, using Ca isotopes) and bedrock dissolution (open vs closed system, using the radiocarbon reservoir effect) from the speleothem δ<sup>13</sup>C signal to derive changes in respired δ<sup>13</sup>C over time. Our approach allows us to estimate the temperature sensitivity of soil respiration (Q<sub>10</sub>), which is higher than current measurements, suggesting that part of the speleothem signal may be related to a change in the composition of the soil respired δ<sup>13</sup>C. This is likely related to changing substrate through increasing contribution from vegetation biomass with the onset of the Holocene.</p><p>These results highlight the exciting possibilities speleothems offer as a coupled archive for quantitative proxy-based reconstructions of climate and ecosystem conditions.</p>
