Science has shown us that since Earth’s creation, climate has been affected by natural occurrences,both within and outside the climate system, but in recent years, climate is also being affected by actions andinactions of the human race. Climate system changes affect all life on earth, but fisheries are affected inparticular, because almost three-quarters of the Earth’s surface is water and home to a variety of aquatic life.Changing weather is producing more droughts, floods, rising sea levels, salt water intrusion of fresh water,acidity in the oceans and ocean warming. This paper discusses how climate change is affecting both marinelife in the oceans and aquatic species in fresh water, as well as the effects of these changes on the seafoodsupply chain and other revenue sources in coastal areas. Factors causing climate change and actions needed tomitigate these changes are also discussed.

Tonga is one of the world’s most exposed countries to climate change and natural disasters. It suffered the highest loss from natural disasters in the world (as a ratio to GDP) in 2018 and is among the top five over the last decade (Table 1). Climate change will make this worse. Cyclones will become more intense, with more damage from wind and sea surges. Rising sea levels will cause more flooding, coastal erosion and contaminate fresh water. Daily high temperatures will become more extreme, with more severe floods and drought.

Global warming will have a significant impact on water resources within the 20 to 30-year planning period of many water projects. Arid and semi-arid regions such as Southern California are especially vulnerable to anticipated negative impacts of global warming on water resources. Long-range water facility planning must consider global climate change in the recommended mix of new facilities needed to meet future water requirements. The generally accepted impacts of global warming include increased temperature, rising sea levels, more frequent and severe floods and droughts, and a shift from snowfall to rain. Precipitation changes are more difficult to predict. For Southern California, these impacts will be especially severe on surface water supplies. Additionally, rising sea levels will exacerbate salt-water intrusion into freshwater and impact the quality of surface water supplies. Integrated water resources planning is emerging as a tool to develop water supplies and demand management strategies that are less vulnerable to the impacts of global warming. These tools include water conservation, reclamation, conjunctive use of surface and groundwater and desalination of brackish water and possibly seawater. Additionally, planning for future water needs should include explicit consideration of the potential range of global warming impacts through techniques such as scenario planning.

AbstractImportant aspects for understanding the effects of climate change on tropical cyclones (TCs) are the frequency of TCs and their tracking patterns. Coastal areas are increasingly threatened by rising sea levels and associated storm surges brought on by TCs. Rice production in Myanmar relies strongly on low-lying coastal areas. This study aims to provide insights into the effects of global warming on TCs and the implications for sustainable development in vulnerable coastal areas in Myanmar. Using TC records from the International Best Track Archive for Climate Stewardship dataset during the 30-year period from 1983 to 2012, a hot spot analysis based on Getis-Ord (Gi*) statistics was conducted to identify the spatiotemporal patterns of TC tracks along the coast of Myanmar. The results revealed notable changes in some areas along the central to southern coasts during the study period. These included a considerable increase in TC tracks (p value < 0.01) near the Ayeyarwady Delta coast, otherwise known as “the rice bowl” of the nation. This finding aligns with trends in published studies and reinforced the observed trends with spatial statistics. With the intensification of TCs due to global warming, such a significant increase in TC experiences near the major rice-producing coastal region raises concerns about future agricultural sustainability.

This short story, “The Archive”, grew out of the eco-critical research I underwent during my postgraduate degree at Goldsmiths, University of London. In recent years, literary studies have become increasingly invested in environmentalism. The damaging consequences of human endeavour are now widely regarded within environmentalist and scientific communities, and by environmental literary theory or “ecocriticism”, as a shift from the Holocene (the geological epoch that provided the appropriate conditions for mammals to thrive), to the “Anthropocene” (the epoch in which human activity has become the dominant driving force of climatic change). The ecological implications of the Anthropocene prompt questions regarding human enterprise and responsibility; fuelling dystopian or apocalyptic end of the world narratives and anxieties towards technology, capitalism and post-humanism. This short piece explores the current problems facing climate change activists, namely the inconsistencies between the scientific community’s attitude towards ecological degradation and popular culture’s. Slajov Zizek suggests that public denial and the disassociation from environmental disaster is not caused by a lack of scientific knowledge, but because we as individuals fail to corroborate what we already know about climate change with our sensory experience of the everyday: ‘We know it, but we cannot make ourselves believe in what we know’. The Archive questions this pervasive delusion, one that denies climate change even in the face of dwindling resources, increasing natural disaster and rising sea levels. We as a society consume natural resources excessively, without any regard for the consequences.  My work draws attention to the suicidal nature of this desire, and encourages its readers to take responsibility for their actions, for the sake of humanity’s survival.

Australia, in common with nations globally, faces an immediate and future environmental and economic challenge as an outcome of climate change. Indigenous communities in Australia, some who live a precarious economic and social existence, are particularly vulnerable to climate change. Impacts are already being experienced through dramatic weather events such as floods and bushfires. Other, more gradual changes, such as rising sea levels in the north of Australia, will have long-term negative consequences on communities, including the possibility of forced relocation. Climate change is also a historical phenomenon, and Indigenous communities hold a depth of knowledge of climate change and its impact on local ecologies of benefit to the wider community when policies to deal with an increasingly warmer world are considered. Non-Indigenous society must respect this knowledge and facilitate alliances with Indigenous communities based on a greater recognition of traditional knowledge systems.

This chapter explains the role of human activities in driving climate change, and some of its most significant impacts. It discusses justice issues raised by climate change, including causal responsibility, future development rights, the distribution of climate change harms, and intergenerational inequity. The chapter also provides a status update on current health inequities, noting the now recognized role of political, economic, commercial, and social factors in determining health. This section also discusses environmental epidemiology and the shift to eco-social approaches and eco-epidemiology, noting that while eco-epidemiologists have begun to research the influence of climate change on health, this research has not yet considered in depth the influence of social systems. The chapter concludes with an overview of how climate change exacerbates existing health inequities, focusing on the health implications of significant climate change impacts, including extreme weather events, rising sea levels, heat stress, vector-borne diseases, and food insecurity.

This article analyses the profound and rapid climate changes that have taken place worldwide in the past two decades and their effects on modern enterprise. Reducing greenhouse gas emissions and developing strategies to adapt to and counterbalance future impacts of climate change sustainably are among the most pressing needs of the world today. Global temperatures are predicted to continue rising, bringing changes in weather patterns, rising sea levels, and increased frequency and intensity of extreme weather events. Such climatic events can have a major impact on households, businesses, critical infrastructure and vulnerable sections of society, as well as having a major economic impact. Therefore, society must prepare to cope with living in a changing climate. The effects of a changing climate have considerable impacts on modern enterprises. In some parts of the world, these impacts are increasingly becoming evident.

Introduction:This study profiles climate change as an emerging disaster risk in Oceania. The rationale for undertaking this study was to investigate climate change and disaster risk in Oceania. The role of this analysis is to examine what evidence exists to support decision-making and profile the nature, type, and potential human and economic impact of climate change and disaster risk in Oceania.Aim:To evaluate perceptions of climate change and disaster risk in the Oceania region.Methods:Thirty individual interviews with participants from 9 different countries were conducted. All of the participants were engaged in disaster management in the Oceania region as researchers, practitioners in emergency management, disaster health care and policy managers, or academics. Data collection was conducted between April and November 2017. Thematic analysis was conducted using narrative inquiry to gather first-hand insights on their perceptions of current and emerging threats and propose improvements in risk management practice to capture, monitor, and control disaster risk.Results:Interviewees who viewed climate change as a risk or hazard described a breadth of impacts. Hazards identified included climate variability and climate-related disasters, climate issues in island areas and loss of land mass, trans-nation migration, and increased transportation risk due to rising sea levels. These emerging risks are reflective of both the geographical location of countries in Oceania, where land mass due to rising oceans has been previously reported and climate change-driven migration of island populations.Discussion:Climate change was perceived as a significant contemporary and future risk, and as an influencing factor on other risks in the Oceania region.

Successful adaptation to climate change requires flexible adaptation strategies which consider regional ecological, economic and social circumstances. Coastal zones are considered to be significantly vulnerable to climate change impacts. The projected impacts of climate change in the metropolitan region of Bremen–Oldenburg, Germany (a coastal area), are, for example, rising sea level, salt water intrusion, temporary groundwater scarcity in the summer and increased (heavy) rainfalls. This paper uses an existing framework, the Adaptive Capacity Wheel (ACW), complemented by two additional dimensions: adaptation motivation and adaptation belief. The objectives were first, to assess the adaptive capacity of water governance in the study region, and second, to show how the ACW can be used as an approach and a communication tool with stakeholders to identify strengths and weaknesses. Based on this, a further objective was to discover what lessons and recommendations can be drawn that could help water experts and stakeholders in the future. The results show a high adaptive capacity and that the addition of the psychological dimensions was valuable. However, it is important to look closely at each dimension assessed by the ACW. The key recommendations are: to improve public participation; to ensure better coordination; to raise awareness; and to reduce the lack of political will to overcome adaptation barriers.

Climate change is predicted to have a major impact on people’s lives with the recent extreme weather events and varying abnormal temperature profiles across the world raising concerns. The impacts of global warming are already being observed, from rising sea levels and melting snow and ice to changing weather patterns. Scientists state unequivocally that these trends cannot be explained by natural variability in climate alone. Human activities, especially the burning of fossil fuels, have warmed the earth by dramatically increasing concentrations of heat-trapping gases in the atmosphere; as these concentrations increase, the more the earth will warm. Climate change and related extreme weather events are being exacerbated sooner than has previously been considered and are already adversely affecting ecosystems and human health by increasing the burden and type of disease at a local level. Changes to the marine environment and freshwater supplies already affect significant parts of the world’s population and warmer temperatures, especially in more temperate regions, may see an increased spread and transmission of diseases usually associated with warmer climes including, for example, cholera and malaria; these impacts are likely to become more severe in a greater number of countries. This review discusses the impacts of climate change including changes in infectious disease transmission, patterns of waterborne diseases and the likely consequences of climate change due to warmer water, drought, higher rainfall, rising sea levels and flooding.
