Summary for Decision Makers from the first regional assessment of short-lived climate pollutants in the Latin America and Caribbean (LAC) region. Through this assessment, policy makers and implementers will be able to better quantify and understand the relevant emissions in the region; identify which measures are most important for delivering near-term climate and air pollution benefits; and estimate the reductions in regional air pollutants that could be achieved by implementing these measures, with associated health and crop-yield benefits for the LAC region.

The Working Group I contribution to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) provides a comprehensive assessment of the physical science basis of climate change. It considers in situ and remote observations; paleoclimate information; understanding of climate drivers and physical, chemical, and biological processes and feedbacks; global and regional climate modelling; advances in methods of analyses; and insights from climate services. It assesses the current state of the climate; human influence on climate in all regions; future climate change including sea level rise; global warming effects including extremes; climate information for risk assessment and regional adaptation; limiting climate change by reaching net zero carbon dioxide emissions and reducing other greenhouse gas emissions; and benefits for air quality. The report serves policymakers, decision makers, stakeholders, and all interested parties with the latest policy-relevant information on climate change. Available as Open Access on Cambridge Core.

This report identifies LAC countries’ main climate change policy priorities, which were discussed through a series of Regional Policy Dialogues and Expert Workshops and complements these with findings of recent analyses by the OECD and other international partners. It explores issues related to their implementation on climate adaptation, mitigation, and cross-cutting policy areas.

World leaders have made a forceful statement that climate change is the greatest challenge facing humanity in the 21st century. However, little progress has been made in implementing policies to address climate change. In Climate Uncertainty and Risk, eminent climate scientist Judith Curry shows how we can break this gridlock. This book helps us rethink the climate change problem, the risks we are facing and how we can respond to these challenges. Understanding the deep uncertainty surrounding the climate change problem helps us to better assess the risks. This book shows how uncertainty and disagreement can be part of the decision-making process. It provides a road map for formulating pragmatic solutions. Climate Uncertainty and Risk is essential reading for those concerned about the environment, professionals dealing with climate change and our national leaders.

This handbook covers the air quality/air pollution from the viewpoints of causing impacts on human/ecosystem health and climate change. Traditionally, air pollution has been a concern mainly in terms of its impacts on human health, and it is still an immediate public and governmental concern in most Asian countries. However, in recent years so-called extreme weather events, such as stronger tropical cyclones, flooding, drought, and other phenomena, have been manifested causing tremendous losses of human lives and properties. Importantly, climate models tell us that such extreme weather events are actually induced by anthropogenic global warming. It has been pointed out that mitigation or alleviation of such climate change leading to the extreme weather events in the next 30 years can be possible only by reducing air pollutants with positive radiative forcing such as ozone or methane, which are called short-lived climate pollutants (SLCPs). Here, concerns about mitigation of air pollutants from the points of human health and climate change have merged. This book covers different kinds of air pollutants and radiative forcers and how they can be measured. It also mentions the situation of air pollutants in different continents and their regional impacts to human health, environment and economy as well as their link to extreme weather events. The book presents how the air pollution and climate change can be mitigated and how clean air technologies and international initiatives for co-controlling air pollution and climate change have been developed.

The past, present, and possible future of the agency designed to act as "the world's environmental conscience." The United Nations Environmental Programme (UNEP) was founded in 1972 as a nimble, fast, and flexible entity at the core of the UN system--a subsidiary body rather than a specialized agency. It was intended to be the world's environmental conscience, an anchor institution that established norms and researched policy, leaving it to other organizations to carry out its recommendations. In this book, Maria Ivanova offers a detailed account of UNEP's origin and history. Ivanova counters the common criticism that UNEP was deficient by design, arguing that UNEP has in fact delivered on much (though not all) of its mandate.
