water, so it seemed rather counterintuitive to drill and chip through the ice to reach the frigid water below. The US Arctic Research Commission wrote that: “We know more about the topography of the planets Venus and Mars than we do about the bathymetry of the Arctic Ocean.” As I stared down at the outlines of the ice hole we had created, it struck me as truly remarkable that such a small window could provide so much new knowledge. The US federal budget for space exploration is just over 1,000 times larger than that for ocean exploration. While there is no question that exploring the Universe helps us to understand many things about this world, knowing if there is life on Mars is not critical to life on this planet; healthy oceans are. As Arthur C. Clark once wrote, “How inappropriate to call this planet Earth when it is quite clearly Ocean.” As we argue about the status of the environment and what should be done about it, we fail to take action that should be universally embraced: to allow our decisions to be guided by science, and to act in the best interests of future generations. What understanding we do have has led us to a chilling conclusion: that humans are drastically altering the climate, both by emitting huge amounts of CO2 and by altering the land through agriculture and urbanization in such a way that the stable climate that saw humans thrive for the first millennia of our history is being unbalanced. According to a report by the World Wildlife Fund we use 1.5 times the amount of resources that Earth can replenish each year. We are like farmers eating our seeds. There is urgency in understanding the world around us, if not for us, than for our children. My grandfather, Jacques Cousteau, often shared with me a simple dream: that every child born has the right to walk on clean grass under a blue sky, breath fresh air and drink pure water. I believe that his is a dream we all share, and that in order to realize it, we must base our decisions on science, not on wishful thinking.

About the Authors
Dr. Kirstin Dow is Professor of Geography at the University of South Carolina. She is the Principal Investigator of the Carolinas Integrated Sciences and Assessments. CISA is part of a NOAA-sponsored network of teams working at the regional level to advance understanding of climate impacts on society and to improve the value and accessibility of climate science for decision-making. CISA research and collaboration with regional decision-makers also supports the US National Climate Assessment. Her research contributions to this interdisciplinary team focus on climate impacts, vulnerability, adaptation, and communicating uncertainty. Kirstin’s PhD focused on the global to local processes shaping vulnerability for fishing communities along the Straits of Malacca (Geography, Clark University). She is the former Manager of the Poverty and Vulnerability Programme at the Stockholm Environment Institute. Currently, she is a Lead Author in the Intergovernmental Panel on Climate Change fifth assessment, contributing to analysis of adaptation. She also serves on the National Academy of Sciences Board on Atmospheric Sciences and Climate, as an Editor of the American Meteorological Society journal Weather, Climate, and Society, and as a science advisor on climate change for community and national efforts. She seeks to inform a transition to a sustainable pathway that recognizes the climate and development challenges in the USA and abroad. Dr. Thomas E. Downing is President and CEO of the Global Climate Adaptation Partnership (GCAP). GCAP is a new initiative, to provide knowledge-led, climate change adaptation solutions for its clients, training through the Adaptation Academy, and advanced knowledge management services. Tom retains a Visiting Professor position at Oxford University in the School of Geography and Environment and is an Associate in development studies in Queen Elisabeth House. He was formerly Executive Director of the Stockholm Environment Institute’s office in Oxford. Tom’s early career included four years working with the Government of Kenya on environmental assessment, drought, and sustainable development. His PhD was on drought coping strategies in central and eastern Kenya (Geography, Clark University). His major interests are sustainable land and water management, including extensive experience in vulnerability assessment and climate risk management. Involved in all five of the assessments of the Intergovernmental Panel on Climate Change, more recently he has led assessments on the economics of climate change, including adaptation planning, extreme events, and end-use effectiveness for vulnerable populations. His current work on mainstreaming climate adaptation in the African Development Bank highlights practical means for institutional readiness and guidelines for measuring climate protection at the project level. Tom continues to develop practical tools for making sound decisions in order to meet the climate challenges ahead.

The year 2010 may well be seen with hindsight as pivotal. It started badly, with the detritus of the Copenhagen Conference of Parties, and chaos around the future of international negotiations. Then, a series of climate extremes rekindled attention. The floods in Australia, China, and Pakistan left unforgettable images of inundation. The Chinese and Russian droughts were of a staggering scale. As we write, another crisis in the Horn of Africa is looming, recalling images of the 1970s famines. There were new entries in the league tables for extreme events, where Bangladesh and the USA dominated headlines. And budget crises continued to remind us of global economic volatility. Mostly behind the scenes, the international negotiations reconvened, making progress in Cancún. Trust in the process was restored to some extent, if not full confidence in reaching final agreements. By 2011, the Arab Spring captured our imaginations with its realignment of global politics. Attention to the future of the planet is widespread as we near the 20th anniversary of the original Earth Summit in Rio (Rio+20) – another pivotal moment and touchstone for reflection. In this Atlas of Climate Change, each double-page spread introduces central issues in current debates about the physical processes, likely impacts, and adequate responses. We noted in the introduction to the first edition some of our motivation: After listening to shrill warnings of catastrophe, dismissive statements from skeptics, decades of calls for more research, incomplete stories of the complexities of negotiations, and confusion over the level of consensus in scientific understanding, we sought to provide a resource to help people make that initial step into understanding the core issues of climate change. This third edition updates and expands upon the climate story, from increasingly common signs of change and the undisputed basics of the science, through the panoply of drivers and consequences, finishing with the status of international action and personal and public commitments to solutions. Many of the pieces of the puzzle in this story have been known for some time. Increasingly the pieces are illuminating details of the big picture. In this introduction we reflect on what we have seen and learned since 2005, when we began the first edition. There have been substantial changes surrounding the understanding and treatment of climate change. As we collated the evidence, again, reviewed major points, and reflected, we are personally deeply concerned. Uncertainty remains, but it is absolutely clear that forestalling action on that basis is to invite other problems and losses. Uncertainty is no longer an excuse for inaction. These are our key messages, sources of inspiration and challenges for the times ahead. Almost all governments have committed to action on climate change Signatories to the UN Framework Convention on Climate Change, most of the countries in the world, have committed to preventing “dangerous anthropogenic [human-induced] climate change”, the key objective of the Convention. In Cancún, countries went further in marking their commitments. The Conference of Parties confirmed that “climate change is one of the greatest challenges of our time.” The Cancún Agreements (registered as decision 1/CP.16, or FCCC/ CP/2010/7/Add.1) further affirmed: • Scaled-up overall mitigation efforts that allow for the achievement of desired stabilization levels are necessary, with developed country Parties showing leadership by undertaking ambitious emission reductions and providing technology, capacity-building and financial resources to developing country Parties… • Adaptation must be addressed with the same priority as mitigation… • Recognizes that warming of the climate system is unequivocal
