The United States has enduring national and strategic interests in the polar regions, including citizens living above the Arctic circle and three year-round scientific stations in the Antarctic. Polar icebreaking ships are needed to access both regions. Over the past several decades, the U.S. government has supported a fleet of four icebreakersâ€"three multi-mission U.S. Coast Guard ships (the POLAR SEA, POLAR STAR, and HEALY) and the National Science Foundation's PALMER, which is dedicated solely to scientific research. Today, the POLAR STAR and the POLAR SEA are at the end of their service lives, and a lack of funds and no plans for an extension of the program has put U.S. icebreaking capability at risk. This report concludes that the United States should continue to support its interests in the Arctic and Antarctic for multiple missions, including maintaining leadership in polar science. The report recommends that the United States immediately program, budget, design, and construct two new polar icebreakers to be operated by the U.S. Coast Guard. The POLAR SEA should remain mission capable and the POLAR STAR should remain available for reactivation until the new polar icebreakers enter service. The U.S. Coast Guard should be provided sufficient operations and maintenance budget to support an increased, regular, and influential presence in the Arctic, with support from other agencies. The report also calls for a Presidential Decision Directive to clearly align agency responsibilities and budgetary authorities.

Of the Coast Guard¿s (CG) 3 polar icebreakers, 2 ¿ Polar Star and Polar Sea ¿ have exceeded their intended 30-year service lives. Potential policy issues for Congress regarding CG polar icebreaker modernization include: the numbers and capabilities of polar icebreakers the CG will need in the future; whether to provide these icebreakers through construction of new ships or service life extensions of Polar Start and/or Polar Sea; whether new ships should be funded entirely in the Coast Guard budget, or partly or entirely in some other part of the fed. budget; and whether the Polar Star should be repaired and placed back into service.

In response to the Chief of Naval Operations (CNO), the National Research Council appointed a committee operating under the auspices of the Naval Studies Board to study the national security implications of climate change for U.S. naval forces. In conducting this study, the committee found that even the most moderate current trends in climate, if continued, will present new national security challenges for the U.S. Navy, Marine Corps, and Coast Guard. While the timing, degree, and consequences of future climate change impacts remain uncertain, many changes are already underway in regions around the world, such as in the Arctic, and call for action by U.S. naval leadership in response. The terms of reference (TOR) directed that the study be based on Intergovernmental Panel on Climate Change (IPCC) scenarios and other peer-reviewed assessment. Therefore, the committee did not address the science of climate change or challenge the scenarios on which the committee's findings and recommendations are based. National Security Implications of Climate Change for U.S. Naval Forces addresses both the near- and long-term implications for U.S. naval forces in each of the four areas of the TOR, and provides corresponding findings and recommendations. This report and its conclusions are organized around six discussion areas-all presented within the context of a changing climate.

Global warming has had a dramatic impact on the Arctic environment, including the ice melt that has opened previously ice-covered waterways. State and non-state actors who look to the region and its resources with varied agendas have started to pay attention. Do new geopolitical dynamics point to a competitive and inherently conflictual “race for resources”? Or will the Arctic become a region governed by mutual benefit, international law, and the achievement of a widening array of cooperative arrangements among interested states and Indigenous peoples? As an Arctic nation Canada is not immune to the consequences of these transformations. In Canada and the Changing Arctic: Sovereignty, Security, and Stewardship, the authors, all leading commentators on Arctic affairs, grapple with fundamental questions about how Canada should craft a responsible and effective Northern strategy. They outline diverse paths to achieving sovereignty, security, and stewardship in Canada’s Arctic and in the broader circumpolar world. The changing Arctic region presents Canadians with daunting challenges and tremendous opportunities. This book will inspire continued debate on what Canada must do to protect its interests, project its values, and play a leadership role in the twenty-first-century Arctic. Forewords by Senator Hugh Segal and former Minister of Foreign Affairs and of National Defence Bill Graham.

The thawing Antarctic continent offers living space and marine and mineral resources that were previously inaccessible. This book discusses how revisiting the Antarctic Treaty System and dividing up the continent preemptively could spare the world serious conflict. The Antarctic Treaty and related agreements—collectively known as the Antarctic Treaty System (ATS)—regulate the seventh continent, which is the only continent without a native human population. The main treaty within the ATS came into force in 1961 and suspended all territorial claims in Antarctica. The Antarctic Environmental Protocol followed in 1998 and prohibited any minerals exploitation in the continent. With this prohibition up for review in 2048, this book asks whether the Antarctic Treaty can continue to protect Antarctica. Doaa Abdel-Motaal—an expert on environmental issues who has traveled through the Arctic and Antarctic—explains that the international community must urgently turn its attention to examining how to divide up the thawing continent in a peaceful manner. She discusses why the Antarctic Treaty is unlikely to be an adequate measure in the face of international competition for invaluable resources in the 21st century. She argues that factors such as global warming, the growth in climate refugees that the world is about to witness, and the increasingly critical quest for energy resources will make the Antarctic continent a highly sought-after objective. Readers will come to appreciate that what has likely protected Antarctica so far was not the Antarctic Treaty but the continent's harsh climate and isolation. With Antarctica potentially becoming habitable only a few decades from now, revisiting the Antarctic Treaty in favor of an orderly division of the continent is likely to be the best plan for avoiding costly conflict.
