The greatest polar expedition of all time : the Arctic mission to the epicenter of climate change
\"A captain's tell-all about the world's largest Arctic expedition--an illuminating account of seafaring adventure, Arctic natural history, and cutting-edge climate science. The book about the Mosaic Expedition: as seen in the documentary film Arctic Drift, Atmospheric scientist Markus Rex recounts the monumental Arctic expedition he captained for one year in this gripping and authoritative book. A groundbreaking step towards understanding the climate crisis, the MOSAiC expedition--launched in 2019 by the Alfred Wegener Institute for Polar and Marine Research--was the first of its kind, journeying deep into the epicentre of climate change, the Arctic, to seek hard-to-find and potentially world-changing scientific data. Rex begins with life aboard the Polarstern, a powerful icebreaker ship that is frozen into fragile ice and carried across the Arctic by the Transpolar Drift. Away from the rest of the world, the team prepares for life under brutal conditions, constructing \"cities\" and \"towns\" on the ice where they will study the Arctic ecosystem, its atmosphere, ocean, sea ice, and more. A terrifying feat that had never been attempted before, the team of hundreds of scientists perform their research during terrifying storms, cracking ice floes, frost-bite, and even quarantines as Covid-19 sweeps the globe. But there are heartwarming moments, too, as Markus Rex describes Christmas parties on the ice and polar bears playing with scientific equipment like puppies. He muses on expeditions past, such as the ill-fated Franklin Expedition, and Fridtjof Nansen's Fram expedition, which he follows as a guide. And he explores answers to the pressing questions facing the Arctic today: How will climate change impact this precious ecosystem--and therefore the rest of the world? What is the best way to protect the Arctic? Interweaving history, science, and memoir, The Greatest Polar Expedition of All Time is a page-turner about the teamwork it takes to complete a risky goal, all in the name of understanding--and responding to--the climate crisis.\"-- Provided by publisher.

Cold Front
The Arctic: land of ice and the midnight sun; irresistible goal for explorers and adventurers; enduring source of romance and mystery - and now also a poignant and imperative indicator of the impact of climate change. As the ice cap shrinks, the geography of the entire arctic region changes: clear shipping channels replace immovable ice and inaccessible oil resources become available.What are the long-term consequences of these cataclysmic changes - not only environmental but also political and social? How will the lives of those who depend on the natural resources of the Arctic be changed? And how will global powers who wish to exploit the region's many assets respond?In August 2008, for the first time in recorded human experience, the two historic routes across the Arctic Ocean - the North-East Passage known to the Russians as the 'Northern Sea Route', and the North-West Passage through the Canadian archipelago - were simultaneously open and ice-free. This rare coincidence caused widespread alarm, prompting fears of renewed competition between Russia and the West over control of the arctic region. Cold Front assesses this impending arctic metamorphosis and its profound effect on international geo-politics. As well as the environmental drama that may accompany an ice-free North Pole - melting glaciers, rising sea levels and severe meteorological disturbance including the possible disruption of the Gulf Stream - David Fairhall explores the potential military, legal and economic implications which could be equally dramatic.Cold Front is not just another attempt to predict the outcome of global warming. It offers a clear-sighted and penetrating investigation of the Arctic's pivotal role in international relations, placing the polar region in its historical, political and legal context. The thawing the of the ice cap creates huge opportunities for
trade and transport - and therefore potentially also for conflict between the arctic nations. This important and timely addition to the literature on the region will be essential reading for anyone interested in humanity's effect on the Arctic - or the Arctic's effect on humanity.

Brave new Arctic : the untold story of the melting North
In the 1990s, researchers in the Arctic noticed that floating summer sea ice had begun receding. This was accompanied by shifts in ocean circulation and unexpected changes in weather patterns throughout the world. The Arctic's perennially frozen ground, known as permafrost, was warming, and treeless tundra was being overtaken by shrubs. What was going on? Brave New Arctic is Mark Serreze's riveting firsthand account of how scientists from around the globe came together to find answers. In a sweeping tale of discovery spanning three decades, Serreze describes how puzzlement turned to concern and astonishment as researchers came to understand that the Arctic of old was quickly disappearing--with potentially devastating implications for the entire planet. Serreze is a world-renowned Arctic geographer and climatologist who has conducted fieldwork on ice caps, glaciers, sea ice, and tundra in the Canadian and Alaskan Arctic. In this must-read book, he blends invaluable insights from his own career with those of other pioneering scientists who, together, ushered in an exciting new age of Arctic exploration. Along the way, he accessibly describes the cutting-edge science that led to the alarming conclusion that the Arctic is rapidly thawing due to climate change, that humans are to blame, and that the global consequences are immense. A gripping scientific adventure story, Brave New Arctic shows how the Arctic's extraordinary transformation serves as a harbinger of things to come if we fail to meet the challenge posed by a warming Earth.

Linkages Between Arctic Warming and Mid-Latitude Weather Patterns
The Arctic has been undergoing significant changes in recent years. Average temperatures are rising twice as fast as they are elsewhere in the world. The extent and thickness of sea ice is rapidly declining. Such changes may have an impact on atmospheric conditions outside the region. Several hypotheses for how Arctic warming may be influencing mid-latitude weather patterns have been proposed recently. For example, Arctic warming could lead to a weakened jet stream resulting in more persistent weather patterns in the mid-latitudes. Or Arctic sea ice loss could lead to an increase of snow on high-latitude land, which in turn impacts the jet stream resulting in cold Eurasian and North American winters. These and other potential connections between a warming Arctic and mid-latitude weather are the subject of active research.
Linkages Between Arctic Warming and Mid-Latitude Weather Patterns is the summary of a workshop convened in September 2013 by the National Research Council to review our current understanding and to discuss research needed to better understand proposed linkages. A diverse array of experts examined linkages between a warming Arctic and mid-latitude weather patterns. The workshop included presentations from leading researchers representing a range of views on this topic. The workshop was organized to allow participants to take a global perspective and consider the influence of the Arctic in the context of forcing from other components of the climate system, such as changes in the tropics, ocean circulation, and mid-latitude sea surface temperature. This report discusses our current understanding of the mechanisms that link declines in Arctic sea ice cover, loss of high-latitude snow cover, changes in Arctic-region energy fluxes, atmospheric circulation patterns, and the occurrence of extreme weather events; possible implications of more severe loss of summer Arctic sea ice upon weather patterns at lower latitudes; major gaps in our understanding, and observational and/or modeling efforts that are needed to fill those gaps; and current opportunities and limitations for using Arctic sea ice predictions to assess the risk of temperature/precipitation anomalies and extreme weather events over northern continents.

Scientific Value of Arctic Sea Ice Imagery Derived Products
During the 1990s, a government program brought together environmental scientists and members of the intelligence community to consider how classified assets and data could be applied to further the understanding of environmental change. As part of the Medea program, collection of overhead classified imagery of sea ice at four sites around the Arctic basin was initiated in 1999, and two additional sites were added in 2005. Collection of images during the summer months at these six locations has continued until the present day. Several hundred unclassified images with a nominal resolution of 1 meter have been derived from the classified images collected at the 6 Arctic sites.
To assist in the process of making the unclassified derived imagery more widely useful, the National Research Council reviewed the derived images and considered their potential uses for scientific research. In this book, we explore the importance of sea ice in the Arctic and illustrate the types of information-often unique in its detail-that the derived images could contribute to the scientific discussion.

Arctic amplification is caused by sea-ice loss under increasing CO 2
Warming in the Arctic has been much faster than the rest of the world in both observations and model simulations, a phenomenon known as the Arctic amplification (AA) whose cause is still under debate. By analyzing data and model simulations, here we show that large AA occurs only from October to April and only over areas with significant sea-ice loss. AA largely disappears when Arctic sea ice is fixed or melts away. Periods with larger AA are associated with larger sea-ice loss, and models with bigger sea-ice loss produce larger AA. Increased outgoing longwave radiation and heat fluxes from the newly opened waters cause AA, whereas all other processes can only indirectly contribute to AA by melting sea-ice. We conclude that sea-ice loss is necessary for the existence of large AA and that models need to simulate Arctic sea ice realistically in order to correctly simulate Arctic warming under increasing CO
