Even as the evidence of global warming mounts, the international response to this serious threat is coming unraveled. The United States has formally withdrawn from the 1997 Kyoto Protocol; other key ...nations are facing difficulty in meeting their Kyoto commitments; and developing countries face no limit on their emissions of the gases that cause global warming. In this clear and cogent book-reissued in paperback with an afterword that comments on recent events--David Victor explains why the Kyoto Protocol was never likely to become an effective legal instrument. He explores how its collapse offers opportunities to establish a more realistic alternative.
As scientific and observational evidence on global warming piles up every day, questions of economic policy in this central environmental topic have taken center stage. But as author and prominent ...Yale economist William Nordhaus observes, the issues involved in understanding global warming and slowing its harmful effects are complex and cross disciplinary boundaries. For example, ecologists see global warming as a threat to ecosystems, utilities as a debit to their balance sheets, and farmers as a hazard to their livelihoods.
In this important work, William Nordhaus integrates the entire spectrum of economic and scientific research to weigh the costs of reducing emissions against the benefits of reducing the long-run damages from global warming. The book offers one of the most extensive analyses of the economic and environmental dynamics of greenhouse-gas emissions and climate change and provides the tools to evaluate alternative approaches to slowing global warming. The author emphasizes the need to establish effective mechanisms, such as carbon taxes, to harness markets and harmonize the efforts of different countries. This book not only will shape discussion of one the world's most pressing problems but will provide the rationales and methods for achieving widespread agreement on our next best move in alleviating global warming.
This book provides useful insight into how academics from diverse disciplinary backgrounds, such as science, engineering, technology, social science, policy, design, architecture, built environment, ...business, and management, have been conducting research into how to realise net zero emissions to address climate change. This book explores the ways in which countries around the world have pledged to achieve net zero emissions through decarbonisation processes. It presents the highest calibre research and impact activities carried out in the UK, Europe, North America, Australia, Asia, and Africa. Such activities include conceptualisation, opportunity identification, specific case studies, demonstration of proof of concepts, provision of evidence, education of the general public, and knowledge transfer to companies. Further to this, the chapters also bring to light personal career journeys to net zero by current and future international research leaders. From this book, readers will gain a full understanding of net zero research via multiple disciplinary pathways, be inspired by personal accounts, and will learn key methodologies, including quantitative and qualitative approaches. The diversity of authors and topics make the book widely applicable to a range of fields, and it will be of great interest to researchers, students, practitioners, and decision makers working towards the goals of net zero and decarbonisation.
The COVID-19 crisis has revealed the close relationship between environmental risks and those to the foundations of human well-being - and the cascading effects on the economy and society. It has ...also highlighted the importance of anticipation and early action. These are also key to integrating climate policy into regional development, albeit on a larger scale. As with COVID-19, the climate challenge is global, but the response needs to build on regional and local actors, natural environments, geographies and infrastructures. The 2021 edition of the OECD Regional Outlook shows that a place-based approach is vital for resilience in the face of both these challenges. It analyses the different territorial impacts of COVID-19 on health and economy, as well as policy responses. The report explores the different territorial implications of moving to net-zero greenhouse gas emissions by 2050 whilst adapting to inevitable climate change, and provides fresh analysis of regional data. It provides insights for integrating the climate challenge into multi-level governance, urban and rural development so as to leave no region behind. It highlights the opportunity we have to draw lessons from COVID-19 for a place-based response to the climate challenge.
Heatwaves are a critical public health problem. There will be an increase in the frequency and severity of heatwaves under changing climate. However, evidence about the impacts of climate change on ...heatwave-related mortality at a global scale is limited.
We collected historical daily time series of mean temperature and mortality for all causes or nonexternal causes, in periods ranging from January 1, 1984, to December 31, 2015, in 412 communities within 20 countries/regions. We estimated heatwave-mortality associations through a two-stage time series design. Current and future daily mean temperature series were projected under four scenarios of greenhouse gas emissions from 1971-2099, with five general circulation models. We projected excess mortality in relation to heatwaves in the future under each scenario of greenhouse gas emissions, with two assumptions for adaptation (no adaptation and hypothetical adaptation) and three scenarios of population change (high variant, median variant, and low variant). Results show that, if there is no adaptation, heatwave-related excess mortality is expected to increase the most in tropical and subtropical countries/regions (close to the equator), while European countries and the United States will have smaller percent increases in heatwave-related excess mortality. The higher the population variant and the greenhouse gas emissions, the higher the increase of heatwave-related excess mortality in the future. The changes in 2031-2080 compared with 1971-2020 range from approximately 2,000% in Colombia to 150% in Moldova under the highest emission scenario and high-variant population scenario, without any adaptation. If we considered hypothetical adaptation to future climate, under high-variant population scenario and all scenarios of greenhouse gas emissions, the heatwave-related excess mortality is expected to still increase across all the countries/regions except Moldova and Japan. However, the increase would be much smaller than the no adaptation scenario. The simple assumptions with respect to adaptation as follows: no adaptation and hypothetical adaptation results in some uncertainties of projections.
This study provides a comprehensive characterisation of future heatwave-related excess mortality across various regions and under alternative scenarios of greenhouse gas emissions, different assumptions of adaptation, and different scenarios of population change. The projections can help decision makers in planning adaptation and mitigation strategies for climate change.
Without significant reductions of greenhouse gas emissions, climate change will cause substantial damage to the environment and the economy. The scope of the threat demands a close look at the ...policies capable of reducing the harm.Confronting the Climate Challengepresents a unique framework for evaluating the impacts of a range of U.S. climate-policy options, both for the economy overall and for particular household groups, industries, and regions. Lawrence Goulder and Marc Hafstead focus on four alternative approaches for reducing carbon dioxide emissions: a revenue-neutral carbon tax, a cap-and-trade program, a clean energy standard, and an increase in the federal gasoline tax. They demonstrate that these policies-if designed correctly-not only can achieve emissions reductions at low cost but also can avoid placing undesirable burdens on low-income household groups or especially vulnerable industries.Goulder and Hafstead apply a multiperiod, economy-wide general equilibrium model that is distinct in its attention to investment dynamics and to interactions between climate policy and the tax system. Exploiting the unique features of the model, they contrast the shorter- and longer-term policy impacts and focus on alternative ways of feeding back-or "recycling"-policy-generated revenues to the private sector. Their work shows how careful policy design, including the judicious use of policy-generated revenues, can achieve desired reductions in carbon dioxide emissions at low cost, avoid uneven impacts across household income groups, and prevent losses of profit in the most vulnerable U.S. industries. The urgency of the climate problem demands comprehensive action, andConfronting the Climate Challengeoffers important insights that can help elevate policy discussions and spur needed efforts on the climate front.
