Dynamic response of Antarctic Peninsula Ice Sheet to potential collapse of Larsen C and George VI ice shelves

first_imgIce shelf break-up and disintegration events over the past 5 decades have led to speed-up, thinning, and retreat of upstream tributary glaciers and increases to rates of global sea-level rise. The southward progression of these episodes indicates a climatic cause and in turn suggests that the larger Larsen C and George VI ice shelves may undergo a similar collapse in the future. However, the extent to which removal of the Larsen C and George VI ice shelves will affect upstream tributary glaciers and add to global sea levels is unknown. Here we apply numerical ice-sheet models of varying complexity to show that the centennial sea-level commitment of Larsen C embayment glaciers following immediate shelf collapse is low ( < 2.5 mm to 2100,  < 4.2 mm to 2300). Despite its large size, Larsen C does not provide strong buttressing forces to upstream basins and its collapse does not result in large additional discharge from its tributary glaciers in any of our model scenarios. In contrast, the response of inland glaciers to a collapse of the George VI Ice Shelf may add up to 8mm to global sea levels by 2100 and 22mm by 2300 due in part to the mechanism of marine ice sheet instability. Our results demonstrate the varying and relative importance to sea level of the large Antarctic Peninsula ice shelves considered to present a risk of collapse.last_img read more

Photo: courtesy of C Morrison/Pixabay. Talos Energy and its partners have secured a two-year contract term extension of their production sharing contract (PSC) for offshore Block 7 in Mexico’s Sureste Basin, which contains the Zama oil discovery.The US-based oil and gas company is the operator of Block 7 where it is partnered by Wintershall DEA’s Sierra Oil & Gas and Premier Oil.The extension for the offshore Mexican block has been granted by the National Hydrocarbons Commission of Mexico (CNH). The partners have also secured regulatory approvals to undertake additional exploration activities on Block 7.CNH approved modified exploration plan for Sureste Basin blockThe CNH has approved the partners’ modified exploration plan for the Sureste Basin block as well. The expanded plan enables the partners to assess additional exploration prospects on the offshore Mexican block in the future which comes in the wake of the completion of the appraisal of the Zama discovery in June 2019.The Block 7 consortium has marked various potential exploration targets, which include the Xlapak and Pok-A-Tok prospects. Each of the additional prospects in the Sureste Basin is estimated to have gross unrisked resources ranges between 75-150 million barrels of oil equivalent (MMBoe).The prospects are said to be oil bearing with similarly-aged sands as those seen in the drilling programme related to the Zama discovery and its appraisal to be targeted.According to Talos Energy, the additional inventory identified by the partners in the Sureste Basin is within close proximity to the Zama oil discovery, which potentially gives scope for substantial development cost synergies if the drilling campaign succeeds.Talos Energy said that the consortium is continuing discussions regarding its Zama unitization plan with Petróleos Mexicanos (Pemex), while moving ahead simultaneously with its front-end engineering and design (FEED) work. The consortium expects to take a final investment decision (FID) on developing the Zama oil discovery in 2020.Talos president and CEO Timothy Duncan said: “We are excited about the additional potential of these prospects, all of which could be incremental to our world-class Zama discovery, the first by the private sector in Mexico’s history.“Finally, we believe these approvals, in combination with the significant increase in industry activity, are yet another indicator of the tremendous potential of the basin in the future.”last_img read more

Colleges fail to pay the Oxford Living Wage

first_imgNo Oxford colleges pay staff the Oxford Living Wage, which is set by Oxford City Council.Freedom of Information (FOI) requests sent by Cherwell reveal that St. Anne’s and Wycliffe Hall also do not pay the real living wage to all employees, which is currently set at £8.75 an hour by the Living Wage Foundation.The Chair of the Oxford Living Wage Review, Councillor Mark Ladbrooke, called for all Oxford employers “to go the extra mile and pay their staff the Oxford Living Wage.”The Oxford living wage, of £9.69 and hour, is set by Oxford City Council to account for the higher cost of living in Oxford.Oxford is the least affordable city in the UK after London, with an average house price more than eleven times higher than the average gross earnings in the city, according to Lloyd’s Bank. Wycliffe Hall pay four staff below the living wage whilst St. Anne’s pay casual labourers at a lowest rate of £7.50 per hour, the government’s living wage.A spokesmen for Wycliffe Hall told Cherwell: “Wycliffe Hall would love to pay all its employees the living wage, and is actively working towards being able to do so as soon as possible.”The government’s living wage is different to the real living wage, which takes account of higher costs of living around the UK.Last term it was revealed that only one third of Oxford Colleges were accredited by the Living Wage Foundation.These included Jesus, Christ Church, Hertford, Somerville, Mansfield, Merton, and Queen’s.Accreditation means that an institution has a “moral commitment” to the living wage and raises its pay levels to match those set by the foundation. Cherwell asked colleges who are not already accredited whether they would look for accreditation.Keble, Balliol, Teddy Hall, and Lincoln were among those who said they had no plans for accreditation, despite paying all staff at least the real living wage.Only Regent’s Park said that they were looking to gain accreditation.The Oxford Living Wage Campaign told Cherwell: “The Living Wage Campaign values transparency and wage security for workers, and remains committed to Living Wage accreditation in Oxford’s colleges.”“We are currently building campaigns in several colleges and hope to see movement in this direction in the future, and onwards to an Oxford Living Wage for all workers.”The FOIs also revealed the top level of pay for college employees. Among those who provided data, All Souls’ warden was paid the highest wage, earning £134,313 per year.The top paid staff members of both Somerville and Balliol earned more than £100,000 per year.Councillor Mark Ladbrooke of Oxford City Council said: “More than 40 Oxford employers are accredited by the Living Wage Foundation, and we would like to see more sign up.“Paying staff the Living Wage helps them to live with dignity, and being an accredited employer is good for business, as it helps to improve staff motivation, retention and customer service.“It’s often said that Oxford has London prices with Midlands wages – and in the case of housing we are more unaffordable than London.“That’s why we pay the higher Oxford Living Wage to all our staff and agency workers, and why we require contractors with contracts over £100,000 to pay it to their staff.”A spokesperson for St. Hilda’s College told Cherwell: “The Oxford Living Wage is set by Oxford City Council as a minimum wage for its own workers.“It has no statistical underpinning and is arbitrarily set at 95% of the London Living Wage (as determined by the Living Wage Foundation).“We do not believe that it is an authoritative measure.”The Principal Bursar of St John’s, Prof Andrew Parker, said: “St John’s is committed to meeting and paying the expectations of the living wage as set by the Living Wage Foundation each year.“Given the College’s stated commitment to following the living wage, we do not see that seeking accreditation will make an effective difference to our staff.”Oxford Student Union said: “Oxford SU believes that people should be paid enough to live decently, and the best way to ensure this is to support a Living Wage. Oxford SU believes that employees of the University and its Colleges should be paid the real Living Wage.”Cherwell sent FOI requests to 33 Oxford colleges and received 23 replies.St Anne’s did not reply to a request for comment and Oxford University declined to comment.last_img read more

R. Kelly Sued for Sexual Battery, False Imprisonment, Transmitting Sexual Disease

first_imgA Texas woman named Faith A. Rodgers filed a lawsuit against R. Kelly in a Manhattan court on Monday. According to the New York Times, the suit alleges sexual battery, false imprisonment, and failure to disclose a sexually transmitted disease.The suit, which seeks unspecified damages, claims that Rodgers met the 51-year-old R&B star after a concert in San Antonio last March when she was 19. The two remained in contact over the phone for a few months before Kelly flew her to New York City, where the suit alleges he “initiated unwanted sexual contact” such as “non-consensual oral and vaginal intercourse” in a hotel room. The suit also alleges that Kelly did not tell Rodgers he was infected with herpes and she contracted the disease (failure to disclose a sexually transmitted disease is a criminal act).Rodgers claims that she continued her relationship with Keller for roughly a year, during which he “routinely engaged in intimidation, mental, verbal and sexual abuse, during and after sexual contact.” Rodgers contends that it was “behavior designed to humiliate, embarrass, intimate and shame her,” and that Kelly regularly recorded her without her consent during sex. She added that he often kept her locked in secluded areas as a form of punishment and control.“Unfortunately, the facts and background of this case are not unique,” the lawsuit says. “This is a run-of-the-mill R. Kelly sexual abuse case.”Rodgers filed an anonymous police report against Kelly in Dallas last month, but her identity wasn’t revealed until she filed the lawsuit on Monday. Rodgers’ lawyer, S. Lee Merrit, told the New York Times that legal action was taken Texas and New York because incidents occurred in both states. Representatives for R. Kelly and his label RCA Records did not respond to requests for comment.Monday’s lawsuit highlights the latest accusations against R. Kelly, who has been accused of sexually abusing and coercing women in what amounts to a “sex cult.” In recent weeks, numerous members of the singer’s inner circle have cut ties with him, and Spotify and Apple Music have limited access to his music.[H/T – Billboard]last_img read more

Fall leaves

first_imgMany people enjoy the beautiful colors that mark the beginning of fall, but the reason why the leaves put on this show and start falling from the trees is often overlooked or misunderstood. Leaf colorDuring the spring and summer, trees are constantly producing a type of sugar called glucose through photosynthesis — the process plants use to turn water, carbon dioxide and sunlight into food. The trees store this glucose in the tree as a stored energy source for winter. They collect this sugar by breaking down the chlorphyll in their leaves. The chlorophyll in a tree’s leaves captures light and makes photosynthesis possible. It also gives plants their green color. There are other pigments in leaves but they are asked by the chlorophyll and the green hue prevails. During the fall and winter, because of changes in the length of daylight and changes in temperature, the trees shut down their food-making factories. As chlorophyll in the leaves breaks down, the green color begins to disappear. The veins that transport fluids from the tree branches to the leaves begin to close, and a layer of cells forms to clog the veins. This action traps different pigments — anthocyanins and carotenoids— in the leaves, resulting in the brilliant fall colors. Anthocyanins contain red and purple hues while Carotenoids exhibit orange, yellow and brown hues. Timing and color variation of leaf change depend on the tree species. Sourwood leaves often change color and fall off while most other species are still green. Oaks tend to be the last to change color. The exact color that each tree displays is dependent on the amount and types of pigment contained in its leaves. Oaks usually turn red or brown; poplars turn golden yellow; dogwoods turn purple-red; and maples have varying colors depending on the type. Temperature, light and water are the primary factors that influence the duration of fall color and how vibrant the colors appear. For example, low temperatures will produce red hues in maple due to Anthocyanin production. Decreased sunlight, from overcast days, can actually increase the intensity of fall color. Adequate soil moisture also seems to have an effect on color change. Drought conditions throughout the summer can delay the onset of fall color and lessen its intensity. Early frosts tend to decrease the amount of colors displayed. Rainy days and cool nights tend to produce the best fall colors. Falling leavesAfter the leaves put on their annual show — it’s time to get out the rake.Leaves fall because the veins that supply nutrients to the leaves close in the fall. Without nutrients or moisture, deciduous tree leaves drop from the tree.Deciduous trees drop their leaves as protection against cold temperatures. Leaves are the tender parts of the tree and are susceptible to freeze damage. Most deciduous leaves are fairly delicate, so dropping them minimizes cold damage to the trees. An exception to the deciduous tree rule is the oak tree. Oak leaves do not detach until new growth emerges in the spring. Evergreen trees, like pines and spruce, keep their leaves or needles because their leaves have a wax-like coating that can survive through several seasons before being shed for new growth.

Oil major Total buys controlling stake in 1,140MW Scottish offshore wind farm

first_img FacebookTwitterLinkedInEmailPrint分享Bloomberg:Total has bought a 51% stake from utility SSE Plc in the development of a massive wind farm off the coast of Scotland.The 70-million-pound investment ($88 million) in the Seagreen 1 wind farm will be Total’s first significant foray into offshore wind as it seeks to expand its green energy business. SSE could also be in line for future payments of 60 million pounds based on certain performance conditions, Total said.As European countries increasingly turn to wind farms at sea to deliver low-carbon power, the project is a first step for the oil major to become a significant player in the industry.As part of an announcement that it reached financial close on the 1,140 megawatt project, SSE said it’ll also buy 30% of the wind farm’s power capacity. Last year, the company secured a contract with the government to sell about 40% of the power at a fixed price of 41.61 pounds per megawatt hour.“It could be the perfect project for exposure to evolving offshore wind projects,” said Tom Harries, a wind analyst at BloombergNEF. “If you are an oil and gas company wanting to go big in offshore then you want to know how future projects might look, not the old stuff.”Total now has stakes in 5 gigawatts of renewable-power capacity. It targets a portfolio of 25 gigawatts by 2025.[William Mathis, Francois de Beaupuy]More: Total begins clean energy shift with Scottish wind farm investment Oil major Total buys controlling stake in 1,140MW Scottish offshore wind farmlast_img read more

Outdoor Updates: North Carolina experiences the third shark attack this month

first_imgFor the first time ever in its 59-year history, the Mount Washington Road Race witnessed its first tie when Brittni Hutton, of Lubbock, Texas and Heidi Caldwell, of Craftsbury Common, Vermont, crossed the finish line at the exact same time, in 1:16:17. The men’s winner, Eric Blake of West Hartford, Connecticut, won the race for the fourth time, breaking the finish line tape in 1:02:52. All three of the winners will take home $1,000 in prize money. On June 10, a 19-year-old surfer reported being bitten by a shark in Ocean Isle; the shark left a deep tooth mark on the surfer’s foot that required surgery. And on June 3, a 17-year-old girl was attacked by a shark and suffered massive injuries, losing a part of her leg and some fingers. Despite the recent incidences, shark attacks are extremely rare. In 2018 there were only 66 unprovoked shark attacks worldwide. The Mount Washington Road Race is a grueling all-uphill footrace to Mount Washington’s 6,288-foot summit via the Mount Washington Auto Road. Runners travel 7.6 miles and gain 4,650 vertical feet to reach the top of the Northeast’s highest peak.

Chile Announces Proposal for Telescope for Which Spain Is Also Competing

first_img The Chilean proposal includes the donation of land on Cerro Armazones, a mountain in Antofagasta, in the northern part of the country, and the creation of a protected area that will include not only the region in which the new telescope would be built, but also Paranal Observatory. Chile has announced its proposal to become the site for the European Extremely Large Telescope (E-ELT), the world’s largest, for which the Spanish Canary Islands are also competing, the local press reported. In Chajnantor, the ESO is building, along with its international partners, the Atacama Large Millimeter/submillimeter Array (ALMA), the world’s largest astronomy project, to study the coldest and most distant bodies in the universe. In addition, with the installation of the E-ELT, the South American country would consolidate its standing as one of the world’s principal locations for astronomy, since it already hosts three European Southern Observatory (ESO) centers. The Ministry of Foreign Affairs expects to submit the proposal, details of which were announced yesterday in Santiago, to the European Southern Observatory (ESO) before 15 February, with the Observatory’s response due at the beginning of March. By Dialogo February 10, 2010 At the moment, the personnel of the Paranal Observatory use gas to generate the electricity that supplies the center, but the government is committing itself to supplying the E-ELT from one of the two systems, thereby reducing its operating costs considerably. These are the La Silla Observatory, in the northern region of Coquimbo; Paranal, about forty kilometers from Cerro Armazones, where the Very Large Telescope (VLT) was installed; and Chajnantor, fifty kilometers from San Pedro de Atacama. In this way the Chilean government aims to guarantee that mining projects that might reduce the number of clear nights in the north of the country, which average 350 a year compared to 280 in the Canary Islands, will not be carried out in the region. Another attraction of the Chilean bid consists in improving the infrastructure in the region, since the region of the Paranal and Armazones mountains receives energy from neither the Central nor the Northern Interconnected System. The Chilean proposal also foresees the possibility of reducing the percentage of observation hours, now at ten percent, reserved for Chilean scientists at foreign centers located on Chilean territory.last_img read more
