Evidence of marine ice-cliff instability in Pine Island Bay from iceberg-keel plough marks

first_imgMarine ice-cliff instability (MICI) processes could accelerate future retreat of the Antarctic Ice Sheet if ice shelves that buttress grounding lines more than 800 metres below sea level are lost1, 2. The present-day grounding zones of the Pine Island and Thwaites glaciers in West Antarctica need to retreat only short distances before they reach extensive retrograde slopes3, 4. When grounding zones of glaciers retreat onto such slopes, theoretical considerations and modelling results indicate that the retreat becomes unstable (marine ice-sheet instability) and thus accelerates5. It is thought1, 2 that MICI is triggered when this retreat produces ice cliffs above the water line with heights approaching about 90 metres. However, observational evidence confirming the action of MICI has not previously been reported. Here we present observational evidence that rapid deglacial ice-sheet retreat into Pine Island Bay proceeded in a similar manner to that simulated in a recent modelling study1, driven by MICI. Iceberg-keel plough marks on the sea-floor provide geological evidence of past and present iceberg morphology, keel depth6 and drift direction7. From the planform shape and cross-sectional morphologies of iceberg-keel plough marks, we find that iceberg calving during the most recent deglaciation was not characterized by small numbers of large, tabular icebergs as is observed today8, 9, which would produce wide, flat-based plough marks10 or toothcomb-like multi-keeled plough marks11, 12. Instead, it was characterized by large numbers of smaller icebergs with V-shaped keels. Geological evidence of the form and water-depth distribution of the plough marks indicates calving-margin thicknesses equivalent to the threshold that is predicted to trigger ice-cliff structural collapse as a result of MICI13. We infer rapid and sustained ice-sheet retreat driven by MICI, commencing around 12,300 years ago and terminating before about 11,200 years ago, which produced large numbers of icebergs smaller than the typical tabular icebergs produced today. Our findings demonstrate the effective operation of MICI in the past, and highlight its potential contribution to accelerated future retreat of the Antarctic Ice Sheet.last_img read more

Balliol divests from fossil fuels

first_imgThe plans include selling some holdings and making alternative investments where necessary, however, this applies to extractors, and not necessary to oil service companies or drilling equipment manufacturers. This includes what the Chair of Balliol’s Investment Committee, Richard Collier, has described, as a “significant reduction in the College’s fossil fuel investments,” from approximately 2.4% of its total endowment to a target of less than 1%, with a view to reducing this further over time. In light of Monday’s announcement, Fergus Green of the Oxford Climate Justice Campaign welcomed Balliol joining the select group of divesting colleges. He added, “The student body is angry at years of obfuscation and delay on climate action and Oxford cannot ignore this pressure any longer.” In a statement released on the Balliol College website, the role of students was directly referenced as the driving force behind the decision, citing students’ concern about the College’s investment policy provoking a “response” from the Investment Committee. Reacting to the decision, the student Balliol Divestment Campaign commented, “We’re thrilled that Balliol has decided to align itself with a just and sustainable future, and has realised that such a future is incompatible with the continued burning of fossil fuels.” Responding to the further commitments made by the College, the Co-Director of People and Planet, J Clarke, congratulated Balliol on “taking a principled stance on the refusal of donations from those most responsible [for the] climate crisis.” Balliol becomes the fifth Oxford College to announce a shift in policy to one specifically aiming to divest its funds from fossil fuel companies, joining St Hilda’s, Wadham, Wolfson and Oriel. The group added, “We look forward to seeing more and more institutions take this step and join the growing divestment movement.” The announcement puts mounting pressure on other colleges, as well as the OUEM, to change their investment policy whilst representing an important victory for divestment campaigners. The fact that Balliol is only the fifth Oxford College to announce a policy of divestment raises serious questions over the University’s commitment to reducing its contribution to the climate crisis. In addition, Balliol announced its aims to encourage greater student-staff collaboration on measures concerning sustainability, guided by the Oxford Climate Action Plan, which will examine how the College can make its policies regarding energy, waste and food more sustainable. The Balliol Divestment Campaign’s work is not over though; the group’s next aim is to reformulate the College’s environmental policy which is argued to be “outdated and not ambitious enough,” despite being written in 2017. Balliol College has announced plans to divest its holdings in fossil fuel companies. The college released a statement on Monday, saying that it planned to reduce its endowment’s fossil fuel exposure, “as far and as fast as practicable.” Students have campaigned for over a year for the College to divest its funds from companies which directly contribute to the climate crisis, and this move undoubtedly represents a victory for those who have pressed for Balliol to shift its policy regarding investment. Not only has Balliol committed to reducing its endowments in fossil fuel exposure, the College committed itself to not soliciting or accepting direct or indirect donations from fossil fuel companies, as well as declaring its intent to join discussions with Oxford University Endowment Management (OUEM), the body which manages the University’s central endowments. The move is not only environmentally significant, it represents an important symbolic shift, as the College’s endowments contribute substantially to its annual income, and thus supports scholarships, bursaries, fellowships and the maintenance of Balliol’s historic buildings. On a university scale, however, Oxford ranks 45th in the People and Planet university league scorecard. The ranking includes such measurements as environmental sustainability, policy and strategy, and would suggest that despite the student success to pressurise a shift in Balliol’s policy, the university as a whole is behind the curve with regards to its divestment policy. Critics would point to the fact that Oxford still has over £200 million in fossil fuel funds, undermining the leading research that members of the University have carried out with regards to climate science. The news comes after an open letter from Fossil Free SJC revealed that St John’s College had invested a combined £8m in BP and Shell, two of the world’s leading fossil fuel extractors with billions of pounds invested in future plans to continue the extraction of oil and gas. This would represent the College divesting at least £1.67 million of its total £119.1 million endowment fund away from fossil fuel extraction companies.last_img read more

News story: Fair rules change after CMA investigation

first_img Giving fairgoers more choice and variety in their local area Improving the quality of rides and fairgoers’ all-round experience Giving councils more power to decide who runs fairs in their area. This will allow them to change the make-up of fairs and refresh under-performing fairs Helping members and non-members of the Guild work together more easily, providing fresh attractions to fairgoers The changes include opening up Guild-run fairs for non-member showmen and reducing restrictions on rival fairs opening close to Guild fairs. They also include practical steps to improve transparency, including publishing the Guild’s rules online, and ensuring objective criteria for membership are explicitly set out.The rule changes were proposed by the Guild following an investigation by the Competition and Markets Authority (CMA). This raised concerns that some of the rules restricted competition, potentially to the detriment of millions of UK fairgoers and showmen.The changes, which were accepted by CMA on 26 October 2017, are aimed at: Following the membership’s vote in favour, the rule changes were ratified at a meeting of the Guild’s Central Council on 17 January 2018 and have now come into force.It remains for the Guild to fulfil its commitment to the CMA to publish its amended rule book online by no later than 31 March 2018. The CMA will continue to monitor the Guild’s progress in this regard and its adherence to its Commitments more generally.The CMA has conducted a number of other investigations into the conduct and rules of trade associations such as those in relation to Property Sales and Lettings, Private Ophthalmology and the Modelling Sector and its work in all these areas, including in the present case, should serve as a wake-up call to trade associations whose rules look to shield their membership from competition.The CMA has produced advice to help trade associations avoid breaking competition law as well as a range of simple guides, including videos, 1-pagers and an online quiz to help smaller businesses understand what to look out for.last_img read more

Students choose post-grad service

first_imgGraduating senior Beth Neiman said the opportunity to volunteer after graduation just fell into her lap.“I heard about Americorps through the [Center for Social Concerns],” Neiman said. “I’ll be teaching at an Indian reservation.”Neiman is one of about 10 percent of seniors going into the volunteer force upon graduation and one of five Notre Dame students who will be teaching on the same reservation.“This year-long program will give me time to decide what to do,” Neiman said.Neiman said she hopes the time she will spend volunteering will teach her life lessons.“This volunteering isn’t really in my field, but it will teach me good life skills,” Neiman said. “I’ll be more able to understand life.”She said the Center for Social Concerns (CSC) aided her search for a volunteering spot.“The CSC is so helpful in sending out lists. I applied to many different things,” Neiman said. “It was a lot of trial and error.”Michael Hebbeler, director of Senior Transitions at the CSC, said volunteer service can be beneficial because it is a way to learn more about the world before pursuing a more permanent career path. “Some students are pretty set on medical school, but they want to do some pretty meaningful work for a year, or they want to gain some sense of focus or direction with their work,” he said. Hebbeler said he sees volunteer service as in agreement with Notre Dame’s mission statement.“In the mission statement, there’s that line about service becoming learning and justice. We’re looking toward building a just world. This is a very hands-on, concrete way of doing it,” Hebbler said.Senior Mary Kate Battle said she wants to go into international development, and her service work at Farm of the Child in Trujillo, Honduras will help.“I wanted to do service before graduate school, not as a break, but as giving back,” Battle said. “The best way to do a job in [international development] is to do service in it.”Battle said the Notre Dame atmosphere fosters a call to service.“Notre Dame is educating the mind in the classroom and the heart through loving service,” Battle said.last_img read more

Outdoor Updates: Falcons abandon Blue Ridge Parkway nests

first_imgThe Bureau of Land Management will pay you $1K to adopt a wild horse N.C. bill would expand “free market” for electric vehicle charging stations A new bill introduced in the North Carolina General Assembly last week would allow electric vehicle charging stations to resell kilowatt-hours originally purchased from an electric utility. Right now, charging stations buy electricity from the utility by the kilowatt-hour but sell the electricity in time increments. Because every electric vehicle consumes electricity at a different rate, an electric vehicle that charges more quickly will pay less than one that charges more slowly for the same amount of electricity delivered. Proponents of the bill say it will help charging stations make a profit, therefore spurring more charging stations around the state, and that additional charging stations will encouraging more North Carolinians to buy electric vehicles. North Carolina’s vehicle market is about half of the national average, with one plug-in vehicle for every 1,000 residents. The state has 565 public charging stations. Peregrine falcons form lifetime bonds and use the same cliff face nest sites year after year to raise their young. Cliffs along the Blue Ridge Parkway have long been used as nest sites by peregrine falcons, including favorite nesting sites at Devil’s Courthouse, located at milepost 422 on the Blue Ridge Parkway. But scientists recently announced that the falcons have abandoned the Devil’s Courthouse nesting sites. Though the cause is unknown, biologists said they believe it’s because of increased human activities at the site, especially people who are leaving marked trails and climbing over safety walls. “This intrusion has likely caused the birds to abandon their nests,” the park announced on their Facebook page. Peregrine falcons nested at Devil’s Courthouse from 2000 to 2007 producing 14 young birds that fledged. Since then, only one fledgling was produced in 2016. Peregrine falcons are listed as a threatened species in North Carolina. center_img Peregrine falcons abandon Blue Ridge Parkway cliff nests Looking for a new pet? The Bureau of Land Management (BLM) will pay people $1,000 to adopt one of the more than the 80,000 wild horses and burros living across the West. Wild horses damage rangeland and often starve when their populations are high. The BLM captures the animals and puts them in corrals, adopting out some of the less feral ones. But most of the corrals are now at capacity and adoption numbers are down, while the number of feral animals out on the range continues to increase. The agency hopes the $1000 incentive will encourage more people to adopt.last_img read more

The birds and the beds: A week in the journey of pandemic preparedness

first_img(CIDRAP Source Weekly Briefing) – The world of pandemic influenza preparedness this past week experienced another roller-coaster ride of public attention—and a lack thereof.I’ve talked about the dilemma of pandemic planning fatigue before, and the events of this week have added to my profound sense that much of the world is slipping even further into such a state. As the menace of pandemic preparedness fatigue rises, fueled by news coverage that downplays concerns, the reports that actually should incite us to action go largely ignored.Let me highlight two examples from the past week that trouble me.The birds…On Monday, the World Organization for Animal Health (OIE) issued a press release, proclaiming: “Today most countries overcome avian influenza outbreaks when they occur.” It generated quite the buzz, but frankly I’m not sure why the OIE issued such a statement because its bottom-line message is unclear.Here’s what we do know:Migratory birds infected with H5N1 avian flu can transmit the virus to domestic poultry, ducks, and geese when they share common areas.Attempts to control the ongoing transmission among domestic birds require early H5N1 detection, containment of domestic bird movement, and slaughtering.As long as migratory birds are infected with the virus, the disease will move back to domestic birds with subsequent contact. This is exactly what’s happening today in Vietnam, where poultry infections have reemerged in multiple provinces after almost 2 years of absence (and another outbreak in domestic birds is being reported as I write).We can’t do much about wild bird infections.The OIE release stated that in the first half of 2007, “Countries reported fewer deaths of wild and migratory birds, which could indicate the disease is coming closer to the end of a cycle.” It concluded that fewer bird infection and death reports mean less real infection in the bird population.But what the OIE did not mention is that the fatigue experienced by local officials in reporting such cases for the past several years—a phenomenon commonly seen during outbreaks of other newly emerging infections in humans and animals—could have played a role in these lower numbers.What’s more, we would expect to see lower wild bird infections several years after the first introduction of a new virus into the bird population, because one of two things happens: (1) the new virus infection kills the birds or (2) any birds that recover are now immune. In epidemiologic terms we call this “burning out all the susceptibles.”But from a scientific perspective, it’s important to note that for several years birds born after such an event reestablish a relatively naive (unexposed) population, and the rapid and significant spread of the virus can start all over again. This also may be what’s happening today in Vietnam.Within hours of the OIE release, a Bloomberg News story, “Avian flu virus may be nearing end as fewer birds die,” received major international attention. I was deluged with phone calls and e-mails over the next 24 hours from business preparedness and public health skeptics who had read the Bloomberg story, convinced they had evidence that the pandemic potential was indeed overblown. That conclusion is just plain wrong.…and the bedsIn contrast to the Bloomberg story, Novation, based in Irving, Tex., which is the healthcare contracting services company of both VHA Inc. and the University HealthSystem Consortium, announced the results of a survey of hospital materials managers on their pandemic preparedness status. Novation found that of the 68 managers who responded:79% reported they could continue operations without external resources for less than a week.54% said they could continue for only 1 to 3 days.Christine Miller, a senior clinical manager at Novation, was quoted in the press release as saying, “Our survey provides some real insight into the supply crisis that hospitals would face during a global flu pandemic.”Was this story picked up by any wire service or trade publication? Not that I could see.Did anyone send it to me or call to discuss its implications? Not one.Yet, I found myself rereading the release several times to take in the full implications of these important results.Bottom line for businessWe are mired in a world of pandemic preparedness fatigue. The voices of skeptics who doubt the eventuality of a pandemic and dismiss the need for preparedness are growing louder. Meanwhile, important studies like the one from Novation are going unnoticed or getting buried. No organization will help itself in the long run by buying into this mindset. There will be a next pandemic, whether it is tomorrow, next year, or even years from now. Like hurricanes, earthquakes, and tsunamis, pandemics happen. Nothing we do today to better prepare for the next pandemic will ever be wasted.Our biggest risk lies in hoping that the Bloomberg headline is right, then one day being proven wrong—deadly wrong.last_img read more

HHS offers tools to promote local pandemic preparedness

first_img Jun 14 CIDRAP News story “HHS hears community leaders’ ideas on pandemic readiness” He said the gap between what public health experts know and what the public knows about pandemic planning is still very large, and more work is needed, particularly on community mitigation efforts that may be needed in a severe pandemic, such as school closures and student dismissals. See also: One component that seems to be missing from the HHS toolkit is a plan for distributing it to community leaders who are well positioned to use the materials, Dworkin said. “As of right now, they are available online, but who knows about them? How will community leaders, school boards, and others learn about their existence?” he asked. Greg Dworkin, MD, founding editor of the Flu Wiki Web site and chief of pediatric pulmonology at Danbury Hospital in Danbury, Conn., told CIDRAP News the materials have been well received. “Interestingly, long-time flu preppers have already used them to discuss the idea with relatives and others who respond to the HHS stamp of legitimacy,” he said. Stephanie Marshall, HHS director of pandemic communications, told CIDRAP News via e-mail that the agency launched a “trade advertising campaign” for the toolkit on Dec 1, the same day the materials were posted on the government’s pandemic planning Web site. She said the ads appear on the toolkit Web site. “Government alone can’t prepare the nation for pandemic flu; this challenge requires your help,” HHS says in its online introduction to the toolkit. “As a leader in your community, you can playa powerful role in encouraging your employees, patients, and members and others whom you represent to prepare by providing information and guidance and by preparing yourself.” The toolkit is an outgrowth of earlier HHS efforts to engage community leaders’ help in preparing the nation for an influenza pandemic. In May the agency hosted a 5-week blog series that was designed to engage community leaders in online discussions about personal preparedness. In June, HHS held a leadership forum in Washington, DC, that drew about 100 leaders from various sectors.center_img Dworkin was one of 13 experts who led the HHS blog discussions and also took part in the agency’s leadership summit. HHS has identified nine communities that it will target with more intensive communication efforts regarding pandemic planning, Marshall said, adding that the agency hopes to introduce that campaign early next year. Titled “Take the Lead: Working Together to Prepare Now,” the 21-item toolkit is aimed at groups such as churches and business, healthcare, and civic organizations. The package of materials, posted on the HHS’ pandemic planning Web site Dec 1, includes several components that groups can adapt to meet their needs, including talking points, checklists, fact sheets, sample e-mails, and sample newsletter articles. The toolkit includes a template that groups can use to publicize campaigns to stockpile food as a community pandemic preparation activity. The package also includes ideas about incentives leaders can use to motivate community members to attend pandemic planning information meetings and related activities. Toolkit materials reflect the input from community leaders, as well as the Centers for Disease Control and Prevention (CDC), HHS said on the Web site. Dec 4, 2007 (CIDRAP News) – The US Department of Health and Human Services (HHS) has released a toolkit to help community leaders educate their constituents about steps they can take to prepare for an influenza pandemic.last_img read more
