August 31, Rapid Arctic ice melt: humans and nature share blame
What has caused the rapid loss of Arctic sea ice over the past few decades? A modelling study says that greenhouse gas emissions have undoubtedly warmed the region, but natural variation in the climate has also played a part.
Jennifer Kay of the National Center for Atmospheric Research in Boulder, Colorado, says that natural variation may allow Arctic summer sea ice to expand again, but only for about a decade. |

August 26, Global Warming May Cause Higher Loss of Biodiversity Than Previously Thought
If global warming continues as expected, it is estimated that almost a third of all flora and fauna species worldwide could become extinct. Scientists from the Biodiversity and Climate Research Centre (Biodiversitat und Klima Forschungszentrum, BiK-F) and the SENCKENBERG Gesellschaft fur Naturkunde discovered that the proportion of actual biodiversity loss should quite clearly be revised upwards: by 2080, more than 80 % of genetic diversity within species may disappear in certain groups of organisms, according to researchers in the title story of the journal Nature Climate Change. The study is the first world-wide to quantify the loss of biological diversity on the basis of genetic diversity.

August 25, NASA Satellites Detect Pothole On Road to Higher Seas
Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world's ocean in response to global warming.
|
August 25, Persistent Organic Pollutants on the move
Persistent Organic Pollutants (POPs) trapped in ice and water for decades may be reentering the environment due to climatic changes.
A recent publication in the journal 'Nature Climate Change' “Revolatilization of persistent organic pollutants in the Arctic induced by climate change” by Jianmin Ma, Hayley Hung, Chongguo Tian & Roland Kallenborn shows that while the banning on many POPs has no doubt had a positive effect on the concentrations measured in the atmosphere, recent climatic changes could be sending some of the more volatile compound back into circulation. |
August 24, Research Vessel Polarstern at North Pole
You can't get any "higher": On 22 August 2011 at exactly 9.42 a.m. the research icebreaker Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association reached the North Pole. The aim of the current expedition is to document changes in the far north. Thus, the researchers on board are conducting an extensive investigation of the water, ice and air at the northernmost point on Earth. The little sea ice cover makes the route via the pole to the investigation area in the Canadian Arctic possible.

August 19, Tourism impacts on historical sites
A new edition in the series “Circumpolar Studies” from The Arctic Centre of the University of Groningen has been published. In his thesis author Ricardo Roura examines the impact of tourism on historical sites in both polar regions and the implications for management.
The thesis entitled ”The footprint of polar tourism: tourist behavior at cultural heritage sites in Antarctica and Svalbard”, illuminates the tourism factor in the decay of historical sites in the polar environments. Part of the book is based on fieldwork at the Netherlands Arctic Station covering cultural heritage in Ny-Alesund and Ny-London in Kongsfjorden. |
August 19, “Dirty” fungi and their intimate relationship to plants
A new study by the Ruhr-Universit?t Bochum (Germany) investigates the distribution of arctic-alpine plants and their accompanying fungal parasite, the smut fungi Microbotryum silenes-acaulis. Smuts fungi are multicellular fungi which are characterized by their large numbers of teliospores. The smuts get their name from a Germanic word for dirt because of their dark, thick-walled and dust-like teliospores.

August 18, Canada "too small" to develop Northwest Passage shipping, diplomat says
Canada will lose out to Russia's Arctic shipping routes because it is too small to finance the infrastructure, France's ambassador for the polar regions said Monday.
Melting polar ice will make Canada's Northwest Passage more accessible in the next decades, but Canada does not seem interested in exploiting it for shipping, said Michel Rocard, who recently returned from a tour of the Arctic aboard the Canadian icebreaker Amundsen. "I have the impression that Canada has given up on the competition to attract a large part of the traffic in 25 or 30 years," Rocard said. |
August 18, Polar Ice Caps Can Recover from Warmer Climate-Induced Melting, Study Shows
A growing body of recent research indicates that, in Earth's warming climate, there is no "tipping point," or threshold warm temperature, beyond which polar sea ice cannot recover if temperatures come back down. New University of Washington research indicates that even if Earth warmed enough to melt all polar sea ice, the ice could recover if the planet cooled again.
|
August 17, Clouds halve the climatic effect of bare ocean
Dwindling sea ice in the Arctic is given a key role in climate change and is feared as a driver of global warming. New research in Troms? shows that clouds halve the climatic effect of the disappearing ice.
Climate scientist Stephen Hudson at the Norwegian Polar Institute has studied the net effect of the severe retreat of the ice around the North Pole. |

August 16, Climate change threatens Arctic cod
Higher sea water temperatures have led to northwards migration of marine species that can create problems for the Arctic cod and other fish stocks in the Barents Sea, scientists believe.
In course of the last 13 years, about 300 southern species have been found in the western part of the Barents Sea or outside Svalbard, a new report from the Norwegian Directorate for Nature Management reads. |
August 16, Visiting students investigate response to climate change
This summer six U.S. students visited Svalbard as part of the five-week REU program (Research Experience for Undergraduates) aiming to understand how arctic glaciers, lakes and fjords respond to changes in the climate.
The Svalbard REU program is cooperation between several American universities and each year six undergraduate students conduct field research in Svalbard. Student research for this project occurs at two field locations in alternate years: Kongsfjorden and Lake Linn?. This year the fieldwork took place in Kongsfjorden targeting on the tidewater glaciers Kronebreen and Kongsvegen. |
August 15, Fluctuations in Arctic sea ice
The extent of the Arctic sea ice is extremely variable. Danish researches have come to this conclusion.
Measuring the extent of sea ice is almost impossible. It constantly breaks off the ice caps in the Arctic and then melts after drifting in the ocean. The Danish researchers say this is the first time that an idea of past sea ice levels has been extracted from the region. |
August 15, Report from the first edition of the Summer Polar School for Italian Science Teachers (SPEs)
The first edition of the Italian Summer School for Science Teachers (SPEs) took place in Genova, Italy, in the period 18-23 July 2011.

August 12, Arctic Ice Melt Could Pause for Several Years, Then Resume Again
Although Arctic sea ice appears fated to melt away as the climate continues to warm, the ice may temporarily stabilize or somewhat expand at times over the next few decades, new research indicates.
The computer modeling study, by scientists at the National Center for Atmospheric Research, reinforces previous findings by other research teams that the level of Arctic sea ice loss observed in recent decades cannot be explained by natural causes alone, and that the ice will eventually disappear during summer if climate change continues. |
August 11,Chinese visitors at the research village of Ny-Alesund
Research director Kim Holmen was among those who received the Chinese delegation that recently visited the research village of Ny-Alesund in Svalbard.
Last year, the Norwegian Polar Institute and the Polar Research Institute of China (PRIC) signed an agreement to collaborate on polar research. The Norwegian-Chinese collaboration on polar research includes cooperation to study glaciers and sea ice, and to facilitate research cruises in the Arctic. |
August 11, Scientists head to Arctic Ocean to track acidification
Scientists from the U.S. Geological Survey will embark next week on an expedition to monitor acidification trends in the Arctic Ocean linked to carbon emissions, the agency said on Wednesday.
The USGS scientists will spend seven weeks on a Coast Guard icebreaker, getting as close to the North Pole as possible to take water samples and test for chemical indicators of acidification, officials said. Carbon emissions are blamed for altering the chemistry of the world's oceans by making them more acidic, which makes it more difficult for fish and other sea life to grow and live. |

Kelly Brunt, a cryosphere specialist at Goddard Space Flight Center, Greenbelt, Md., and colleagues were able to link the calving of icebergs from the Sulzberger Ice Shelf in Antarctica following the Tohoku Tsunami, which originated with an earthquake off the coast of Japan in March 2011. |
August 9, New rules for renting firearms for polar bear protection
The Governor of Svalbard has revised the regulations for firearm rentals. It is now possible to rent rifles for a period of up to 6 months if the renter has a permit to possess a firearm in his/her home country.
The revised rules for renting firearms for polar bear protection on Svalbard open for the possibility of renting rifles to private persons for as much as 6 months. The person renting the rifle must be over 18 years of age and possess a Norwegian firearms permit, a European firearms passport or other papers giving him/her permission to possess a firearm in his/her home country. |
August 9, North Sea Wind Farm Has Positive Net Impact On Fauna, Researchers Say
A North-Sea wind farm has few negative effects on fauna. Most birds avoided the wind turbines, although rotating blades can have a significant disruptive effect on some species of birds. It turns out that a wind farm also provides a new habitat for organisms living on the sea bed such as mussels, anemones, and crabs, thereby potentially contributing to increased biodiversity. For fish and marine mammals, it provides an oasis of calm in a relatively busy coastal area, according to researcher Prof. Han Lindeboom at IMARES, part of Wageningen UR, and several of his colleagues and fellow scientists at Bureau Waardenburg and Royal Netherlands Institute for Sea Research (NIOZ).

August 4, Arctic sea ice hits record low for July: satellite data
Arctic sea ice extent in July 2011 broke its previous record low set for that month in 2007, the National Snow and Ice Data Center said today.
Arctic ice cover reached the lowest level for July recorded by satellites from 1979 to 2011. Average ice extent for this past July was 7.92 million square kilometres. That’s 210,000 km below the previous record low for the month, set in July 2007, reported the NSIDC’s Colorado-based scientists on Aug. 3. |
August 4, Climatologists Forecast Completely New Climates
Geographers have projected temperature increases due to greenhouse gas emissions to reach a not-so-chilling conclusion: climate zones will shift and some climates will disappear completely by 2100. Tropical highlands and polar regions may be the first to disappear, and large swaths of the tropics and subtropics will reach even hotter temperatures. The study anticipates large climate changes worldwide.

August 1, Flying over thinning ice
An unprecedented set of Arctic research flights is providing new sea-ice measurements and helping scientists calibrate similar data from an ice-monitoring satellite.
During a six-week mission that ended in early May, research aircraft from NASA, the European Space Agency (ESA), and the Alfred Wegener Institute (AWI) for Polar and Marine Research in Bremerhaven, Germany, flew over the Arctic Ocean from sites in Alaska, Canada, Greenland and Norway. They sampled the atmosphere at various altitudes to gather meteorological data, and the aircraft towed electromagnetic sensors to measure the thickness of sea ice. These new readings will help researchers calibrate data gleaned by instruments aboard ESA's CryoSat-2 — an ice spy that has orbited Earth at an altitude just above 700 km since it was launched in April 2010. |
August 1, U.S. Polar Research May Slow for Lack of an Icebreaker

July 29, Sea Level Rise Less from Greenland, More from Antarctica, Than Expected During Last Interglacial
During the last prolonged warm spell on Earth, the oceans were at least four meters -- and possibly as much as 6.5 meters, or about 20 feet -- higher than they are now.
|
July 28, Largest Recorded Tundra Fire Yields Scientific Surprises
In 2007 the largest recorded tundra fire in the circumpolar arctic released approximately as much carbon into the atmosphere as the tundra has stored in the previous 50 years, say scientists in the July 28 issue of the journal Nature. The study of the Anaktuvuk River fire on Alaska's North Slope revealed how rapidly a single tundra fire can offset or reverse a half-century worth of soil-stored carbon.

July 26, Eat, Prey, Rain: New Model of Dynamics of Clouds and Rain Is Based On a Predator-Prey Population Model
What do a herd of gazelles and a fluffy mass of clouds have in common? A mathematical formula that describes the population dynamics of such prey animals as gazelles and their predators has been used to model the relationship between cloud systems, rain and tiny floating particles called aerosols. This model may help climate scientists understand, among other things, how human-produced aerosols affect rainfall patterns. The research recently appeared in the Proceedings of the National Academy of Sciences (PNAS).
|
July 26, Time to Take Alaska Out of the Icebox
The Arctic might be the world's final—and possibly most attractive—emerging market.
While most investors are focused on the economic potential of lower latitudes, the Arctic is—due to increased access from climate change—quietly undergoing a radical transformation that is attracting the attention of savvy investors. But the U.S. is asleep at the wheel, leaving some of the world's largest oil, natural gas and mineral resources to be developed by others. |
July 25, 80 Percent of World Climate Data Are Not Computerized and Readily Available
In order to gain a better knowledge of climate variations, such as those caused by global warming, and be able to tackle them, we need to understand what happened in the recent past. This is the conclusion of a research study led by the Rovira i Virgili University (URV), which shows that the scientific community today is only able to access and analyse 20% of the recorded climate information held. The remaining data are not accessible in digital format.
|
July 25, Sea Ice Was So Much Older Then
The extent of the sea ice in the Arctic has arguably been one of the most contentious of the metrics used by climate scientists to monitor the pace and severity of global warming. Since the 1970s the maximum extent of ice coverage in the Arctic Ocean (measured every March) has declined, with some short-term upward bumps along the way but with an overall average rate of loss of about three percent per decade. The minimum extent (measured in September) has declined more rapidly -- at about 11.5 percent per decade.

July 22, Harper gears up for another round of Arctic chest-thumping
Next month, as he has every summer since becoming Prime Minister, Stephen Harper will travel to the Arctic, trumpeting his Conservative government’s resolve to assert Canadian sovereignty in the Far North against all comers.
Little of what he says will accord with reality. But it will all make for splendid political theatre, which is the whole point. |
July 22, Act now on climate, no need to wait: top UN scientist
The key facts on global warming are already known and leaders should not wait for the next edition of the UN climate panel's report to step up action, the body's top scientist told AFP.
The 4th Intergovernmental Panel on Climate Change (IPCC) report, released in 2007, "is very clear," Rajendra Pachauri said Monday in Paris, ahead of a five-day meeting of the body in Brest, France. The fifth multi-volume assessment, which summarizes peer-reviewed science to help policy makers make decisions, is due out in 2013-2014. |
July 21, Divergent long-term trajectories of human access to the Arctic
Understanding climate change impacts on transportation systemsis particularly critical in northern latitudes, where subzero temperatures restrict shipping, but enable passage of ground vehicles over frozen soil and water surfaces. Although the major transport challenges related to climate warming are understood, so far there have been no quantitative projections of Arctic transport system change. Here we present a new modelling framework to quantify changing access to oceans and landscapes northward of 40°N by mid-century.

July 20, Antarctic researchers strive to make better predictions for future sea-level rise
Antarctic geoscientists and ice sheet modellers get together in Edinburgh this week to investigate ways to improve predictions of likely sea-level rise as a result of future ice loss from the West Antarctic Ice Sheet.
Satellite observations and on-the-ice measurements provide evidence of rapid change in the Amundsen Sea Embayment. Glaciers in this region have accelerated their flow towards the coast and ice has become thinner. There is an urgent need for Antarctic scientists from many different countries to work together to pool their knowledge and observations and improve computer simulations to help determine the contribution that this region will make to future sea-level rise. It has been estimated that the Amundsen Sea Embayment contains enough ice to raise global sea level by 1.2 m, but so far scientists are unable to fully explain the true impact of and timescale of future change. |
July 20, What lies beneath? Scientists discuss Antarctica's hidden mountains
Scientists from British Antarctic Survey and institutes around the world discuss ‘what lies beneath the ice’ at the International Symposium of Antarctic Earth Sciences in Edinburgh 15 July.
A session: uncovering and unveiling Antarctica will explore the Gamburtsev Sub-glacial Mountains, in the heart of East Antarctica. These were uncovered during the International Polar Year. It was the first time the geology and topography of the sub-glacial mountains, roughly the size of the European Alps, were mapped using a range of airborne geophysical techniques. |

July 19, Overcoming Barriers to Arctic Ocean Scientific Drilling: The Site Survey Challenge
The IASC Marine Working Group is supporting a workshop on 'Overcoming Barriers to Arctic Ocean Scientific Drilling: The Site Survey Challenge'. The workshop will be lead by Naja Mikkelsen and Bernard Coakley and is scheduled to take place in Copenhagen, Denmark from 1 - 3 November 2011.
The Arctic Ocean is the last essentially un-drilled, un-sampled ocean basin. Arctic deep-sea drilling is the only means to acquire paleo-oceanographic and climatic records, and constrain the tectonic history of the basin.Among other issues, the lack of adequate site survey data and appropriate age models for these data hampers the development of mature drilling proposals. The focus of the workshop is to plan site survey campaigns based on existing and planned proposals and pre-proposals that were developed as a result of the successful 2008 Magellan workshop, "Arctic Ocean History: From Speculation to Reality." |
July 18, Wood Products Part of Winning Carbon-Emissions Equation, Researchers Say
Trees absorb carbon dioxide from the atmosphere to grow, so forests have long been proposed as a way to offset climate change.
But rather than just letting the forest sit there for a hundred or more years, the amount of carbon dioxide taken out of the atmosphere could be quadrupled in 100 years by harvesting regularly and using the wood in place of steel and concrete that devour fossil fuels during manufacturing, producing carbon dioxide. |
July 18, Secret Soviet expeditions to the North Pole
The North Pole is probably the least explored part of Earth despite hundreds or even thousands of expeditions to the land. Its first explorers blazed a firm trail for others lucky enough to visit and discover the land of snow, ice and extreme weather. A Soviet paratrooper, who was one of the first ever to parachute at the North Pole and a pilot, who participated in numerous trainings to the Pole, tell their story.

July 15, NOAA Ship Fairweather sets sail to map areas of the Arctic
NOAA Ship Fairweather, a 231-foot survey vessel, departed Kodiak, Alaska, today on a mission to conduct hydrographic surveys in remote areas of the Arctic where depths have not been measured since before the U.S. bought Alaska in 1867.
NOAA will use the data to update nautical charts to help mariners safely navigate this important but sparsely charted region, which is now seeing increased vessel traffic because of the significant loss of Arctic sea ice. |
July 14, Small, but far from insignificant
They are no bigger than 2mm and yet their total biomass in Svalbard is probably bigger than the biomass of all Svalbard polar bears together! New research can tell us more about how, when and from where the springtails arrived in Svalbard.

July 11, With Climate Changes, Polar Bear and Brown Bear Lineages Intertwine
Polar bears' unique characteristics allow them to survive in one of the most extreme environments on Earth, but that survival is now threatened as rising temperatures and melting ice reshape the Arctic landscape. Now it appears that the stress of climate change, occurring both long ago and today, may be responsible for surprising twists in the bears' history and future as well.

July 11, Svalbard inspiring Youth Climate Activists
Seventeen young climate activists and campaigners visited Svalbard last week in order to learn more about local impacts of climate change and to build a network to further raise awareness about this issue.
During a one-week-long cruise along the Western and Northern coasts of Spitsbergen, the participants underwent an intensive program combining seminars, networking, and observation of the Arctic wildlife. |
July 8, Ancestry of Polar Bears Traced to Ireland
An international team of scientists has discovered that the female ancestor of all living polar bears was a brown bear that lived in the vicinity of present-day Britain and Ireland just prior to the peak of the last ice age -- 20,000 to 50,000 years ago. Beth Shapiro, the Shaffer Associate Professor of Biology at Penn State University and one of the team's leaders, explained that climate changes affecting the North Atlantic ice sheet probably gave rise to periodic overlaps in bear habitats. These overlaps then led to hybridization, or interbreeding -- an event that caused maternal DNA from brown bears to be introduced into polar bears.

July 1, Climate Researchers Seek Global Warming Clues in the Arctic's Svalbard Archipelago
Polar bears are the draw for most visitors to Spitsbergen, the largest island in Norway's Svalbard archipelago. For geoscientist Lee R. Kump of The Pennsylvania State University, however, rocks were the allure. In the summer of 2007 Kump flew to this remote Arctic Ocean island to find rocks that might offer fresh insights about one of Earth's ancient episodes of global warming: the so-called Paleocene–Eocene Thermal Maximum, or PETM. In that event, some 56 million years ago, global temperatures rose 5 degrees Celsius in the course of a few thousand years—a mere instant in geologic time.

June 30, Land Use Change Influences Continental Water Cycle
Forests, and tropical forests in particular, play an important role in the global water cycle. Delft University of Technology PhD researcher Ruud van der Ent (TU Delft, The Netherlands) has recently shown that evaporation from the Amazon forest is for more than 50% responsible for the rainfall in Peru, Bolivia, Argentina, Uruguay, Paraguay and southern Brazil, where it feeds crops and rivers. Similarly in Africa, the Congo forest exports tons of water through the atmosphere to the West-African countries.

June 30, Melting Arctic Ice Marks Possible Sea Change in Marine Ecosystems
A single-celled alga that went extinct in the North Atlantic Ocean about 800,000 years ago has returned after drifting from the Pacific through the Arctic thanks to melting polar ice. And while its appearance marks the first trans-Arctic migration in modern times, scientists say it signals something potentially bigger.
"It is an indicator of rapid change and what might come if the Arctic continues to melt," said Chris Reid, a professor of oceanography at the Sir Alister Hardy Foundation for Ocean Science in the United Kingdom. |

June 28, Polar Bear Diet Makes Them Vulnerable to Sea Ice Loss
Polar bears that rely on fewer prey animals to fill their bellies may be more vulnerable to starvation and stress as climate change ravages the extent of their summer ice hunting platform across the Arctic, according to a profile posted online about a longtime Canadian bear researcher.
Over the past 30 years, Dalhousie University biologist Sara Iverson has been part of an effort that collected fat samples from polar bears throughout the Canadian Arctic, producing a remarkable catalog of what bears eat for dinner and how that diet varies from population to population. |
June 28, Ocean Currents Speed Melting of Antarctic Ice: A Major Glacier Is Undermined from Below
Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A growing cavity beneath the ice shelf has allowed more warm water to melt the ice, the researchers say -- a process that feeds back into the ongoing rise in global sea levels. The glacier is currently sliding into the sea at a clip of four kilometers (2.5 miles) a year, while its ice shelf is melting at about 80 cubic kilometers a year -- 50 percent faster than it was in the early 1990s -- the paper estimates.

June 27, Arctic 'Strait of Gibraltar' unlikely
Arctic shipping is an ice dream unlikely to come true any time soon, the head of one of the world's top shipping companies told The Arctic Imperative Summit here Tuesday.
It was not exactly what some in the audience wanted to hear. A shrinking polar ice cap and a slow but steady increase in ships trafficking the Arctic Ocean along Russia's Northern Route has fueled a belief that direct shipping from Europe to the Far East could be on the horizon. The U.S. Coast Guard has begun referring to the narrow stretch of the Bering Sea between Wales and Naukan, Russia, as "Alaska's Strait of Gibralatar." That notion was pooh-poohed by Capt. Stephen Carmel, senior vice president for Maersk Line, Limited, the globe's leading mover of containerized freight. |
June 27, Prodigal Plankton Species Makes First Known Migration from Pacific to Atlantic Via Pole
Microscopic plant disappeared from North Atlantic 800,000 years ago; unwanted return 1 of several climate change symptoms already apparent throughout European oceans Some 800,000 years ago -- about the time early human tribes were learning to make fire -- a tiny species of plankton called Neodenticula seminae went extinct in the North Atlantic.

June 24, Global warming study suggests more people will die from heat than cold in Europe
A new study says one of the few benefits of global warming — fewer deaths from the combination of extreme heat and cold — may eventually melt away in Europe.
For years, scientists figured that with global warming there are fewer overall temperature-related deaths when those from heat waves and cold snaps are combined. The increase in heat wave deaths during hotter spells is more than offset by reduced cold deaths in milder winters. |
June 23, Russia, Norway may issue Barents, Arctic shelf licenses in 2013
Russia and Norway may start granting licenses to develop offshore deposits in the Barents Sea and the Arctic Ocean in 2013-2014 under a bilateral sea border agreement, Russia's Natural Resources Ministry said on Wednesday.
The Russian-Norwegian agreement on delimiting the sea border and cooperation in the Barents Sea and the Arctic Ocean will come into force on July 7, 2011. The agreement opens new opportunities for the oil and gas industry in the northern regions, the ministry said after a bilateral meeting on the prospects of geological works in the area. |
June 23, Surprises from the Ocean: Marine Plankton and Ocean pH
The world's oceans support vast populations of single-celled organisms (phytoplankton) that are responsible, through photosynthesis, for removing about half of the carbon dioxide that is produced by burning fossil fuels -- as much as the rainforests and all other terrestrial systems combined. One group of phytoplankton, known as the coccolithophores, are known for their remarkable ability to build chalk (calcium carbonate) scales inside their cells, which are secreted to form a protective armour on the cell surface. On a global scale this calcification process accounts for a very significant flux of carbon from the surface ocean, and hence coccolithophores are an important component of the global carbon cycle, as cells die and the calcium carbonate sinks to form ocean sediments.

June 22,Divergent long-term trajectories of human access to the Arctic
Understanding climate change impacts on transportation systemsis particularly critical in northern latitudes, where subzero temperatures restrict shipping, but enable passage of ground vehicles over frozen soil and water surfaces. Although the major transport challenges related to climate warming are understood, so far there have been no quantitative projections of Arctic transport system change. Here we present a new modelling framework to quantify changing access to oceans and landscapes northward of 40°?N by mid-century. The analysis integrates climate and sea-ice model scenarios1, 2 with topography, hydrography, land cover, transportation infrastructure and human settlements. Declining sea-ice concentration and thickness suggest faster travel and improved access to existing (+5 to +28%) and theoretical (+11 to +37%) offshore exclusive economic zones of Canada, Greenland, Russia and the US.

June 22, Carbon balance of Arctic tundra under increased snow cover mediated by a plant pathogen
Climate change is affecting plant community composition1 and ecosystem structure, with consequences for ecosystem processes such as carbon storage. Climate can affect plants directly by altering growth rates1, and indirectly by affecting predators and herbivores, which in turn influence plants. Diseases are also known to be important for the structure and function of food webs. However, the role of plant diseases in modulating ecosystem responses to a changing climate is poorly understood.

June 21, Did Climate Change Cause Greenland's Ancient Viking Community to Collapse?
Our changing climate usually appears to be a very modern problem, yet new research from Greenland published in Boreas, suggests that the AD 1350 collapse of a centuries old colony established by Viking settlers may have been caused by declining temperatures and a rise in sea-ice. The authors suggest the collapse of the Greenland Norse presents a historical example of a society which failed to adapt to climate change.

June 9, APECS Atmospheric Science & Climate Research Group
Welcome to the APECS Atmospheric Sciences and Climate Listserve, where researchers in climate, atmospheric, terrestrial and marine sciences, as well as mathematics, physics, astronomy and all fields in-between are invited to join our online working group. It is generally accepted in the scientific community that climate is undergoing a significant change in which anthropogenic activities constitute an important factor. To be able to understand and mitigate the driving forces of climate change as well as its consequences we need experimental research and modeling studies. Since climate change is most obviously noted in the polar regions polar research can provide very valuable results for general climate science. One of the main goals of this listserve is to discuss some of the central ideas and techniques of climate science.

June 8, From all appearances, Russia is poised to leave Canada out in the cold in the race for Arctic resource supremacy
Russia could beat Canada and the United States in the race for dominance over the Arctic?s vast hydrocarbon potential if a special United Nations (UN) commission recognizes-perhaps as early as 2012-Russia?s right to the extensive Lomonosov Ridge under the Arctic Ocean. Such recognition could give Russia control of up to 60 per cent of any hydrocarbons found in the High Arctic.
According to recent statements of Dmitry Medvedev, Russia?s president, Russia is planning to "more vigorously defend its claims for the development of Arctic fields, amid the attempts of rivals to limit its access to these resources." |
