Policymakers around the world are increasingly concerned about the likely impact of climate change and environmental degradation on the movement of people. This book takes a hard look at the existing evidence available to policymakers in different regions of the world. How much do we really know about the impact of environmental change on migration? How will different regions of the world be affected in the future? Is there evidence to show that migration can help countries adapt to environmental change ? What types of research have been conducted, how reliable is the evidence? These are some of the questions considered in this book, which presents, for the first time, a synthesis of relevant research findings for each major region of the world. Written by regional experts, the book provides a comprehensive overview of the key findings of existing studies on the linkages between environmental change and the movement of people. More and more reports on migration and the environment are being published, but the information is often scattered between countries and within regions, and it is not always clear how much of this information is based on solid research. This book brings this evidence together for the first time, highlighting innovative studies and research gaps. In doing this, the book seeks to help decision-makers draw lessons from existing studies and to identify priorities for further research.

This book applies a justice framework to analysis of the actual and potential role of international law with respect to people on the move in the context of anthropogenic climate change. That people are affected by the impacts of climate change is no longer doubted, including with implications for people movement (migration, displacement, relocation, etc.). Climate Change and People on the Move tackles unique questions concerning international responsibility for people movement arising from the inequities inherent to climate change. Corrective and distributive justice provide the analytical backbone, and are explored in a substantial theoretical chapter and then applied to subsequent contextual analysis. Corrective justice supports analysis as to whether people movement in the climate change context could be conceived or framed as harm, loss, or damage which is compensable under international law, either through fault-centred regimes or no-fault regimes (i.e. insurance). Distributive justice supports analysis as to whether such movement could be conceived or framed as a disproportionate burden, either for those faced with movement or those faced with sheltering people on the move, from which duties of re-distribution may stem. This book contributes to the growing scholarship and analysis concerning international law or governance and people movement in response to the impacts of climate change by investigating the bounds of the law where the phenomenon is viewed as one of (in)justice.

#1 NEW YORK TIMES BEST SELLER • In this urgent, authoritative book, Bill Gates sets out a wide-ranging, practical—and accessible—plan for how the world can get to zero greenhouse gas emissions in time to avoid a climate catastrophe. Bill Gates has spent a decade investigating the causes and effects of climate change. With the help of experts in the fields of physics, chemistry, biology, engineering, political science, and finance, he has focused on what must be done in order to stop the planet's slide to certain environmental disaster. In this book, he not only explains why we need to work toward net-zero emissions of greenhouse gases, but also details what we need to do to achieve this profoundly important goal. He gives us a clear-eyed description of the challenges we face. Drawing on his understanding of innovation and what it takes to get new ideas into the market, he describes the areas in which technology is already helping to reduce emissions, where and how the current technology can be made to function more effectively, where breakthrough technologies are needed, and who is working on these essential innovations. Finally, he lays out a concrete, practical plan for achieving the goal of zero emissions—suggesting not only policies that governments should adopt, but what we as individuals can do to keep our government, our employers, and ourselves accountable in this crucial enterprise. As Bill Gates makes clear, achieving zero emissions will not be simple or easy to do, but if we follow the plan he sets out here, it is a goal firmly within our reach.

The open access publication of this book has been published with the support of the Swiss National Science Foundation. Climate change is forcing us to consider the right of people to leave their disappearing homelands, and the shape this right should take. Climate Change, Disasters and People on the Move proposes international protection as a solution with three pillars: granting protection against return to the country of origin (non-refoulement); preventing future displacement; and facilitating safe, orderly, and regular migration in the context of disasters and climate change. Dr. Aylin Yildiz Noorda uses the theories of common concern of humankind and community interests to operationalise her proposal, providing a blueprint for future claims.

Climate change is occurring. It is very likely caused by the emission of greenhouse gases from human activities, and poses significant risks for a range of human and natural systems. And these emissions continue to increase, which will result in further change and greater risks. America's Climate Choices makes the case that the environmental, economic, and humanitarian risks posed by climate change indicate a pressing need for substantial action now to limit the magnitude of climate change and to prepare for adapting to its impacts. Although there is some uncertainty about future risk, acting now will reduce the risks posed by climate change and the pressure to make larger, more rapid, and potentially more expensive reductions later. Most actions taken to reduce vulnerability to climate change impacts are common sense investments that will offer protection against natural climate variations and extreme events. In addition, crucial investment decisions made now about equipment and infrastructure can "lock in" commitments to greenhouse gas emissions for decades to come. Finally, while it may be possible to scale back or reverse many responses to climate change, it is difficult or impossible to "undo" climate change, once manifested. Current efforts of local, state, and private-sector actors are important, but not likely to yield progress comparable to what could be achieved with the addition of strong federal policies that establish coherent national goals and incentives, and that promote strong U.S. engagement in international-level response efforts. The inherent complexities and uncertainties of climate change are best met by applying an iterative risk management framework and making efforts to significantly reduce greenhouse gas emissions; prepare for adapting to impacts; invest in scientific research, technology development, and information systems; and facilitate engagement between scientific and technical experts and the many types of stakeholders making America's climate choices.

Around the world, from US coastal towns to island nations of the Pacific and the deserts of Africa, people are in danger of losing their homes. Some have already fled. Others know they are running out of time. By 2050, at least 25 million people will be driven from their homes due to the effects of climate change. Droughts, desertification, rising sea levels, melting permafrost, and severe storms are drastically redefining the planet's landscape and leaving many places unable to support human populations. Although developing nations are especially vulnerable to the impacts of extreme climate shifts, ultimately, people in wealthy countries will also be forced to migrate. Experts expect Americans to move from drought-ravaged California, sea-swept Florida, and numerous other vulnerable areas to crowd into the few remaining safe havens. Humans cannot stop climate change altogether. Yet leaders can minimize the damage by curbing carbon dioxide emissions that contribute to climate change and by adapting communities to better withstand climate-related stresses. Even so, for many people, relocation is already a reality. How they adjust to their new homes—and how their new communities adjust to them—will set the stage for a future defined by a warming planet.

This book provides an authoritative analysis of the impact of climate change on migration.

Summarizes the science of climate change and impacts on the United States, for the public and policymakers.

Bjorn Lomborg argues that many of the elaborate and staggeringly expensive actions now being considered to meet the challenges of global warming ultimately will have little impact on the world’s temperature. He suggests that rather than focusing on ineffective solutions that will cost us trillions of dollars over the coming decades, we should be looking for smarter, more cost-effective approaches (such as massively increasing our commitment to green energy R&D) that will allow us to deal not only with climate change but also with other pressing global concerns, such as malaria and HIV/AIDS. And he considers why and how this debate has fostered an atmosphere in which dissenters are immediately demonized.

This report focuses on the possible future scenarios for climate change, natural disasters and migration and development, looking to increase awareness and find answers to the challenges that lie ahead. It states that even though it is defined as a growing crisis, the consequences of climate change for human population are unclear and unpredictable. The study points out that scientific basis for climate change is increasingly well established, and confirms that current predictions as to the "carrying capacity" in large parts of the world will be compromised by climate change.
