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.

"The Arctic Melt: Images of a Disappearing Landscape is a brilliant new monograph by universally acclaimed art and environmental photographer Diane Tuft. Following on the heels of Tuft's previous publication, Gondwana: Images of an Ancient Land, this new book showcases her breathtaking and visually astounding journey to capture the ice in the Arctic Circle before the constant melt renders the once-frozen landscape unrecognizable. The Arctic Melt features photographs of the North Pole, the mountain glaciers of Svalbard, Norway, and the icebergs and ice sheet of Greenland. In a remarkably new take on illustrating the effects of global warming, and with more than fifty stunning photographs, The Arctic Melt chronicles Tuft's passage through the waning tundra as millennia of ice thaw at a faster rate than ever before."--Jacket

Humanity's impact on the natural world can have disastrous effects. Melting Arctic Iceshines a light on how climate change is affecting Earth's polar region. With abundant charts and diagrams and large-format photos, this title explores the science behind greenhouse gases, polar sea ice, and rising sea levels, and considers actions people and governments can take to try to improve the situation. Features include a flow chart showing the disaster's causes and effects, a glossary, references, websites, source notes, and an index. Aligned to Common Core Standards and correlated to state standards. Essential Library is an imprint of Abdo Publishing, a division of ABDO.

Among all the large whales on Earth, the most unusual and least studied is the narwhal, the northernmost whale on the planet and the one most threatened by global warming. Narwhals thrive in the fjords and inlets of northern Canada and Greenland. These elusive whales, whose long tusks were the stuff of medieval European myths and Inuit legends, are uniquely adapted to the Arctic ecosystem and are able to dive below thick sheets of ice to depths of up to 1,500 meters in search of their prey-halibut, cod, and squid. Join Todd McLeish as he travels high above the Arctic circle to meet: Teams of scientific researchers studying the narwhal's life cycle and the mysteries of its tusk Inuit storytellers and hunters Animals that share the narwhals' habitat: walruses, polar bears, bowhead and beluga whales, ivory gulls, and two kinds of seals McLeish consults logbooks kept by whalers and explorers and interviews folklorists and historians to tease out the relationship between the real narwhal and the mythical unicorn. In Colorado, he visits climatologists studying changes in the seasonal cycles of the Arctic ice. From a history of the trade in narwhal tusks to descriptions of narwhals' vocalizations as heard through hydrophones, Narwhals reveals the beauty and thrill of the narwhal and its habitat, and the threat it faces from a rapidly changing world.

Top scientists describe the alarming impacts of glaciers receding half a mile per year, pack ice hundreds of miles farther from the Arctic coast, permafrost melting and villages crumbling into the rising seas. [Publisher web site].

In March 2014, Eric Larsen and Ryan Waters set out to traverse nearly 500 miles across the melting Arctic Ocean, unsupported, from Northern Ellesmere Island to the geographic North Pole. Despite being one of the most cold and hostile environments on the planet, the Arctic Ocean has seen a steady and significant reduction of sea ice over the past seven years due to climate change. Because of this, Larsen’s and Waters’ trip—dubbed the “Last North Expedition”—is expected to be the last human-powered trek to the North Pole, ever. Filled with stunning, full-color photos and GPS maps plotting his progress, On Thin Ice is Larsen’s first-person account of this historic two-man expedition. Traveling across the retreating sea ice on skis, snowshoes, and even swimming through semi-frozen arctic slush, Larsen and Waters each pulled over 320 pounds of gear behind them on sleds through temperatures that plummeted to nearly 70 degrees below zero. At times, they covered little over a mile a day. They were stalked by polar bears and ran out of food. It was, in Larsen’s words, “easily one of the most difficult expeditions in the world.” More than just a heart-stopping adventure narrative, however, On Thin Ice offers an intimate and haunting look at the rapidly changing face of the Arctic due to global climate change.

The Arctic sea ice is characterized by profound changes caused by surface melting processes and the formation of melt ponds in summer. Melt ponds contribute to the ice-albedo feedback as they reduce the surface albedo of sea ice, and hence accelerate the decay of Arctic sea ice. To quantify the melting of the entire Arctic sea ice, satellite based observations are necessary. Due to different spectral properties of snow, ice, and water, theoretically, multi-spectral optical sensors are necessary for the analysis of these distinct surface types. This study demonstrates the potential of optical sensors to detect melt ponds on Arctic sea ice. For the first time, an Arctic-wide, multi-annual melt pond data set for the years 2000-2011 has been created and analyzed.
