First direct evidence that human activity is linked to Antarctic Ice Shelf collapse
October 17, 2006The first direct evidence linking human activity to the collapse of Antarctic ice shelves is published this week in the Journal of Climate. Scientists from the British Antarctic Survey (BAS), the Centre for Polar Observation and Modelling, University College London, and the Katholieke Universiteit Leuven, (Belgium) reveal that stronger westerly winds in the northern Antarctic Peninsula, driven principally by human-induced climate change, are responsible for the marked regional summer warming that led to the retreat and collapse of the northern Larsen Ice Shelf.
Global warming and the ozone hole have changed Antarctic weather patterns such that strengthened westerly winds force warm air eastward over the natural barrier created by the Antarctic Peninsula's 2 km-high mountain chain. On days when this happens in summer temperatures in the north-east Peninsula warm by around 5 degrees C, creating the conditions that allowed the drainage of melt-water into crevasses on the Larsen Ice Shelf, a key process that led to its break-up in 2002.
Lead author Dr Gareth Marshall from the British Antarctic Survey said, "This is the first time that anyone has been able to demonstrate a physical process directly linking the break-up of the Larsen Ice Shelf to human activity. Climate change does not impact our planet evenly - it changes weather patterns in a complex way that takes detailed research and computer modelling techniques to unravel. What we've observed at one of the planet's more remote regions is a regional amplifying mechanism that led to the dramatic climate change we see over the Antarctic Peninsula."

Antarctic Current Events and Antarctic News RSSPast climate of the northern Antarctic Peninsular informs global warming debate
The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented.
Precise picture of early Universe supports 'dark matter' theory
A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by a Cardiff University scientist.
West Antarctic ice sheet may not be losing ice as fast as once thought
New ground measurements made by the West Antarctic GPS Network (WAGN) project, composed of researchers from The University of Texas at Austin, The Ohio State University, and The University of Memphis, suggest the rate of ice loss of the West Antarctic ice sheet has been slightly overestimated.
Whale-sized genetic study largest ever for southern hemisphere humpbacks
After 15 years of research in the waters of the South Atlantic and Indian Oceans, scientists from the Wildlife Conservation Society, the American Museum of Natural History, and an international coalition of organizations have unveiled the largest genetic study of humpback whale populations ever conducted in the Southern Hemisphere.
Last time carbon dioxide levels were this high: 15 million years ago, scientists report
You would have to go back at least 15 million years to find carbon dioxide levels on Earth as high as they are today, a UCLA scientist and colleagues report Oct. 8 in the online edition of the journal Science.
NASA flies to Antarctica for largest airborne polar ice survey
NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions.
Peering under the ice of a collapsing polar coast
Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace far beyond what scientists expected a few years ago.
Laser technique has implications for detecting microbial life forms in Martian ice
An innovative technique called L.I.F.E. imaging used successfully to detect bacteria in frozen Antarctic lakes could have exciting implications for demonstrating signs of life in the polar regions of Mars.
Algae and pollen grains provide evidence of remarkably warm period in Antarctica's history
For Sophie Warny, LSU assistant professor of geology and geophysics and curator at the LSU Museum of Natural Science, years of patience in analyzing Antarctic samples with low fossil recovery finally led to a scientific breakthrough.
New CO2 data helps unlock the secrets of Antarctic formation
The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

Antarctic: A Tribute to Life in the Polar Regions by Michael Poliza (Photographer), HSH Prince Albert II of Monaco (Photographer), David de Rothschild (Photographer), Stefan Schulze-Hausmann (Photographer) Following his stunning photo-safari in Africa and an unprecedented helicopter voyage from Europe to Africa in Eyes Over Africa, the award-winning photographer has ventured to the polar regions. With his inimitable blend of intimate close-ups and cinematic landscapes, Poliza leads us through the magical worlds of these frozen paradises most threatened by global warming. Poliza shows polar bears as they frolicked among purple fireweed against the majestic Arctic backdrop, varied and multicolored icebergs, as well as a number of rare and endangered species. Poliza once again captures the most vulnerable treasures--still ensconced in our planet's few pristine landscapes. |

The Antarctic: From the Circle to the Pole by Stuart Klipper (Photographer), Guy Guthridge (Photographer), William L. Fox (Photographer), Steven Pyne (Photographer) Antarctica remains largely unknown and infinitely fascinating. Stuart Klipper has traveled to Antarctica six times in twenty years to photograph this astounding body of work offering a sweeping look at this majestic continent which has lately become central to global climate change concerns. Shot in panoramic format—the only way to encompass a landscape that seems to stretch on forever—Klipper's work captures major features and surprising details: ships suspended in the frozen sea glowing blue icebergs vistas of endless snow and troops of penguins. This volume's substantial size panoramic shape and unique vertical-opening case emphasize the grandeur of these austere and lovely photographs from the bottom of the world. |

Eyewitness (Nature Series) - Arctic & Antarctic [VHS] Starring: Martin Sheen Which is which? We think of both places as similar ice realms, but Eyewitness: Arctic and Antarctic explains how they are a world apart (both literally and figuratively). The polar regions received their names from the Greeks: the Arctic is so called for the Great Bear, Arctus, in the northern sky; the opposite of that, Antarctic, means "no bear." The story of these icy kingdoms begins with a fairy tale by Hans Christian Anderson, beautifully narrated by Martin Sheen, who goes on to explain the harsh ecosystems. The Arctic is a continent of ice, capable of producing icebergs the size of Belgium. Amazingly, the average iceberg holds enough freshwater to supply a family of five for 100,000 years. This documentary is chock full of facts and information about these icy lands at the top and... | |

Emperors of the Ice: A True Story of Disaster and Survival in the Antarctic, 1910-13 by Richard Farr (Author) Apsley George Benet Cherry-Garrard has always dreamt of becoming an explorer. So in the spring of 1910, when Captain Robert Falcon Scott offers young “Cherry” the position of Assistant Zoologist aboard the Terra Nova, Cherry considers himself the luckiest man alive. Cherry’s luck, however, will soon change. Far off in the icy unknown of Antarctica, where temperatures plummet below –77°F, exploration is synonymous with a struggle for life. Frostbite, scurvy, hidden ice chasms, and packs of hungry killer whales are very real dangers. But even these perils don’t prepare Cherry for the expedition he and two other crew members embark upon to collect the eggs of Emperor penguins. Along the way, he will face the elements head-on, risking life and limb in the name of science. Rife... |
