Anthropocene Antarctica : perspectives from the humanities, law and social sciences
\"Anthropocene Antarctica offers new ways of thinking about the 'Continent for Science and Peace' in a time of planetary environmental change. In the Anthropocene, Antarctica has become central to the Earth's future. Ice cores taken from its interior reveal the deep environmental history of the planet and warming ocean currents are ominously destabilising the glaciers around its edges, presaging sea-level rise in decades and centuries to come. At the same time, proliferating research stations and tourist numbers challenge stereotypes of the continent as the 'last wilderness.' The Anthropocene brings Antarctica nearer in thought, entangled with our everyday actions. If the Anthropocene signals the end of the idea of Nature as separate from humans, then the Antarctic, long considered the material embodiment of this idea, faces a radical reframing. Understanding the southern polar region in the twenty-first century requires contributions across the disciplinary spectrum. This collection paves the way for researchers in the Environmental Humanities, Law and Social Sciences to engage critically with the Antarctic, fostering a community of scholars who can act with natural scientists to address the globally significant environmental issues that face this vitally important part of the planet\"-- Provided by publisher.

Polar cousins : comparing Antarctic and Arctic geostrategic futures
Geopolitics and climate change now have immediate consequences for national and international security interests across the Arctic and Antarctic. The world’s polar regions are contested and strategically central to geopolitical rivalry. At the same time, rapid political, social, and environmental change presents unprecedented challenges for governance, environmental protection, and maritime operations in the regions. With chapters that raise awareness, address challenges, and inform policy options, Polar Cousins reviews the state of strategic thinking and options on Antarctica and the Southern Oceans in light of experience in the circumpolar North. Prioritizing strategic issues, it provides an essential discussion of geostrategic thinking, strategic policy, and strategy development. Featuring contributions from international defence experts, scientists, academics, policymakers, and decisionmakers, Polar Cousins offers key insights into the challenges unique to the polar regions.

Secrets of the ice : Antarctica's clues to climate, the universe, and the limits of life
Antarctica is the only continent without permanent human habitation, yet it may hold the key to our survival. Meduna shows how geologists and glaciologists learn about the implications of today's climate change for the future; how scientists study migration patterns of emperor penguins or examine the microbial evidence that may reveal how life evolved on Earth-- and what it may look like on other planets-- Source other than Library of Congress.

Frozen in Time
No other continent on Earth has undergone such radical environmental changes as Antarctica. In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Antarctica has gone from paradise to polar ice in just a few million years, a geological blink of an eye when we consider the real age of Earth. Frozen in Time presents a comprehensive overview of the fossil record of Antarctica framed within its changing environmental settings, providing a window into a past time and environment on the continent. It reconstructs Antarctica's evolving animal and plant communities as accurately as the fossil record permits. The story of how fossils were first discovered in Antarctica is a triumph of human endeavour. It continues today with modern expeditions going out to remote sites every year to fill in more of the missing parts of the continent's great jigsaw of life.

Austral
The great geoengineering projects have failed. The world is still warming, sea levels are still rising, and the Antarctic Peninsula is home to Earth's newest nation, with life quickened by ecopoets spreading across valleys and fjords exposed by the retreat of the ice. Austral Morales Ferrado, a child of the last generation of ecopoets, is a husky: an edited person adapted to the unforgiving climate of the far south, feared and despised by most of its population. She's been a convict, a corrections officer in a labour camp, and consort to a criminal, and now, out of desperation, she has committed the kidnapping of the century. But before she can collect the ransom and make a new life elsewhere, she must find a place of safety amongst the peninsula's forests and icy plateaus, and evade a criminal gang that has its own plans for the teenage girl she's taken hostage.

The Extraordinary March 2022 East Antarctica “Heat” Wave. Part I: Observations and Meteorological Drivers
Between 15 and 19 March 2022, East Antarctica experienced an exceptional heat wave with widespread 30°–40°C temperature anomalies across the ice sheet. This record-shattering event saw numerous monthly temperature records being broken including a new all-time temperature record of −9.4°C on 18 March at Concordia Station despite March typically being a transition month to the Antarctic coreless winter. The driver for these temperature extremes was an intense atmospheric river advecting subtropical/midlatitude heat and moisture deep into the Antarctic interior. The scope of the temperature records spurred a large, diverse collaborative effort to study the heat wave’s meteorological drivers, impacts, and historical climate context. Here we focus on describing those temperature records along with the intricate meteorological drivers that led to the most intense atmospheric river observed over East Antarctica. These efforts describe the Rossby wave activity forced from intense tropical convection over the Indian Ocean. This led to an atmospheric river and warm conveyor belt intensification near the coastline, which reinforced atmospheric blocking deep into East Antarctica. The resulting moisture flux and upper-level warm-air advection eroded the typical surface temperature inversions over the ice sheet. At the peak of the heat wave, an area of 3.3 million km 2 in East Antarctica exceeded previous March monthly temperature records. Despite a temperature anomaly return time of about 100 years, a closer recurrence of such an event is possible under future climate projections. In Part II we describe the various impacts this extreme event had on the East Antarctic cryosphere.
