"Proceedings of the Fourteenth International Conference on Climate Change: Impacts & Responses, 7-8 April 2022. The conference featured research addressing the following special focus: "Responding to Climate Change as Emergency: Governing the Climate Emergency" and annual themes: The Nature of Evidence: Why the persistent challenge of universalizing evidence based approaches?; Assessing Impacts in Diverse Ecosystems: What are the impacts of climate change on natural environments in particular and universal views?; Human Impacts and Responsibility: How have we been agents of climate change, what does a politics of responsibility reveal?; Technical, Political, and Social Responses: How do scientists, technologies, policy makers, and community members respond to climate change?"--

Not Available ; Governments worldwide and in the U.S. are enacting a variety of measures to mitigate greenhouse gas emissions (GHG) from various economic sectors. Tools to prioritize these measures are generally lacking in analytical rigor. On the other hand, the research literature continues to proliferate with assessments of energy efficiency and GHG mitigation options that can be adapted to the policy evaluation process. This dissertation formulates an analytical method to better prioritize future climate change policy actions. A framework is developed to integrate current research on climate change mitigation technology alternatives from all sectors of the U.S. economy on an equal footing. Applying consistent economic assumptions, a multi-benefit cost-effectiveness accounting tool is developed that simultaneously evaluates the technology costs, lifetime energy saving benefits, and GHG reductions in a single cost-per-tonne-reduced metric. The framework synthesizes the disparate studies' data to compare and prioritize options across sectors as well as determine the aggregate impacts from multiple sectors' GHG mitigation actions. A broad portfolio of cost-effective technologies is available from each major sector of the economy. The findings indicate that there are many net-beneficial "no regrets" climate change mitigation technologies – where the energy savings of the technologies outweigh the initial costs – and most of these technologies are not being widely adopted. Transportation technologies are found to represent approximately half of the "no regrets" mitigation opportunities and about one-fifth of the least-cost GHG mitigation measures to achieve the benchmark 1990 GHG level. With the adoption of known near-term technologies, GHG emissions by 2030 could be reduced by 14% with net-zero-cost technologies, and emissions could be reduced by about 30% with technologies that each have net costs less than $30 per tonne of carbon dioxide equivalent reduced. ; Not Available

This book reviews the influence of climate change on urban and public pests such as mosquitoes, flies, ticks, and wood pests (such as termites), with respect to population, distribution, disease, damage and control. Consisting of 13 chapters, the book systematically addresses how the impact of climate change on pests in urban areas differs from natural areas, focusing on the increased temperatures of urban locations, the effect of natural disasters, the manner of land use and the consequences of human habitation. It highlights key information on how climate change and urban pests affect human health, discusses the effects of natural disasters such as flooding, and looks at issues which could influence the management of pests. It also explores a range of international opinions from recognized authorities covering 6 continents. Presenting up-to-date knowledge, this book is an essential resource for researchers in urban pests, entomology and public health, as well as scientists, environmentalists and policy makers involved in studies on climate change.

Im Auftrag des Presse- und Informationsamts der Bundesregierung untersucht das Meinungsforschungsinstitut Kantar quartalsweise die Einstellungen zum Klimaschutz und die Bewertung politischer Maßnahmen zum Klimaschutz. Im 4. Quartal 2021 bildeten Fragen zu Klimafolgen einen thematischen Schwerpunkt.

The impact of climate change (CC) on water resources is likely to affect agricultural systems and food security. This is especially true for Nepal, a least developed country, where a high percentage of the population is dependent on agriculture for its livelihoods. It is thus crucial for Nepal?s leaders and resource managers to draft and begin implementing national adaptation plans. This working paper aims to create a more comprehensive understanding of how the impacts of CC will be realized at different scales in Nepal, from household livelihoods to national food security, and the many institutions governing the ultimate adaptation process.

"This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students"--
