Past atmospheric composition and chemistry from ice cores – progress and prospects

first_imgIce cores provide the most direct evidence available about the past atmosphere. For long-lived trace gases, ice cores have provided clear evidence that in the last two centuries, concentrations of several greenhouse gases have risen well outside the natural range observed in the previous 650 000 years. Major natural changes are also observed between cold and warm periods. Aerosol components have to be interpreted in terms of changing sources, transport and deposition. When this is done, they can also supply evidence about crucial aspects of the past environment, including sea ice extent, trace element deposition to the ocean, and about the aerosols available for cloud nucleation, for example. It is much more difficult to extract information about shorter-lived chemical species. Information may be available in components such as nitrate and formaldehyde, but to extract that information, detailed modern atmospheric studies about air to snow transfer, preservation in the ice, and the link between the polar region boundary layer and other parts of the atmosphere are urgently required.last_img read more

Dutch OPV nabs 406 kilos of cocaine in Caribbean Sea

first_img View post tag: Dutch Navy The Royal Netherlands Navy offshore patrol vessel HNLMS Friesland has seized 406 kilos of cocaine from a vessel in a joint operation with the Sint Maarten coast guard.The drugs were seized on Thursday after a suspect vessel was spotted by Friesland’s NH90 helicopter.According to the Dutch Navy, the intercepted vessel attracted attention due to its odd position and sailing behavior.Upon noticing the helicopter, the crew of the smuggling vessel started jettisoning packages overboard. The packages were picked up by the crew of the Holland-class OPV and were confirmed to contain cocaine. All of the seized drugs were subsequently destroyed.HNLMS Friesland is currently stationed in the Caribbean on a rotational deployment to Dutch overseas territories where it will stay until the end of November. In addition to drug control operations, the ship is also responsible for rescue operations and humanitarian aid.

Bouncer accused of aggression at Warehouse

first_imgBethanie Curry, one of the organisers of Unity week as JCR President at Corpus Christi, commented, “The behaviour of the security staff in this instance was completely unacceptable. There is never a good reason to treat club-goers in this way. I am especially sad since the event was meant to be celebrating the end of a week of solidarity and liberation: it was an event that was meant to be enjoyed by everyone. I am deeply saddened to hear otherwise”. Thames Valley Police declined to comment on the allegations of a “shameless” attempt to win them over, stating, “We regret that Thames Valley Police is unable to respond to complaints and concerns regarding quality of service received by the police through the media.“We take all complaints seriously and require complaints to be made through official channels so that the details and unique circumstances of the individual’s case can be taken into consideration and investigated by our Professional Standards Department.” Warehouse also declined to comment. “It was a shameless and blatant attempt to win over the police so that the report would be marked as a classic incident of drunken youths getting out of hand and being rowdy, rather than an aggressive, unwarranted attack resulting in a serious injury by one of the bouncers.” Bouncers have been accused of using unnecessary force against a student, as well as criticised for their handling of those involved in the incident following the Unity Bop at Warehouse nightclub on Saturday 23rd May. A first year at Pembroke sustained significant facial injuries when he was removed from Warehouse, sparking concern over bouncers’ conduct. Students present were also unhappy with the way the bouncers communicated with them and the police officers on the scene. The Unity Bop ended the joint equalities week across Pembroke, Corpus Christi, Exeter and Trinity colleges. The student told Cherwell, “I was on the dance floor with a friend when I jokingly pushed him. Thinking that I was trying to initiate a fight, the bouncer came from behind and put my hands behind my back to escort me out of the club. Even though my friend and I tried to tell him that he was mistaken, he didn’t listen and proceeded to throw me out in an extremely aggressive man- ner. He didn’t bother to wait for the doorman to fully open the door and rammed my face into the edge of door due to which I got a massive cut on my lip and broke half my front tooth. “This is all extremely frustrating as all of this could’ve been avoided if the bouncer spared ten seconds to hear us out rather [than] chucking me out with unnecessary aggression and causing permanent damage to my face in the process.” After explaining how the pushes exchanged were “obviously a joke”, the other fresher involved in the incident commented, “The bouncers were very unreasonable! The ones that took the student out said nothing and the others were acting as though there was nothing wrong, as- suming the problem was that he was ‘drunk’. Comparatively the police were very good, consulting everyone outside.” center_img The police report from the incident stated, “Enquiries were made and CCTV footage was viewed,” but that eventually “no offence was found to have taken place” and that it appeared the student concerned “had injured himself on a door”.However Yew Loong, also a first-year at Pembroke and eye witness, fervently disagreed with this conclusion.He told Cherwell, “I first saw a bouncer suddenly and violently grab the student by the side, restraining his arms and pulling him away from a group of other Pembroke students. He was not retaliating or protesting and merely asked what he was being pulled out for. The first bouncer did not give any justification for his actions and instead, another bouncer came and again violently grabbed him from the other side. I followed behind him, whilst calling out to the bouncers that he was not violent and that it was a misunderstanding.“The bouncers took no heed and continued dragging him out of the club as quickly as possible whilst restraining him very tightly. Once they reached the door, they did not slow down or loosen their grip on him. He managed to get through the first door without injury, but upon reaching the second door, he was clearly not ready to go to through it. The bouncers’ action would almost certainly cause injury and using force that was not warranted especially considering that the student did not retaliate when the first bouncer grabbed him.”Fresher Niamh Coote commented, “When I questioned one of the bouncers about the CCTV coverage of the area to assess the situation, another bouncer approached me and started asking me lots of quite rude questions such as whether the friend was my boyfriend because he couldn’t understand why I was ‘emotionally down’ about the situation.“He accused me of ‘fabricating’ the situation and accused another friend from College of punching the guy in the face. The bouncer made me feel very uncomfortable with his questioning until eventually we decided to ‘agree to disagree’ and some friends and I walked home. We spoke to another police officer about the situation as we didn’t feel it had been handled well at all and we were not left with much confidence that our friend was being treated fairly.”With regards to the bouncers’ dealings with the Police, Livvy Iller, a first-year Biochemist, told Cherwell, “Two police men walking by saw there had been an incident and walked over. Immediately the ‘head’ bouncer greeted one of them by name, shook his hand, and started chatting away about how they had shared a stint on the force together.last_img read more

Students reject move to end the wearing of scholars’ gowns

first_imgStudents have overwhelming voted against a motion on whether OUSU should oppose the wearing of scholars’ gowns in examinations.In a consultation poll, 2126 students voted against the motion that OUSU should oppose the wearing of differential gowns in examinations, with 1214 in favour, and 33 abstentions. The poll was open for two days and received a total turnout of 3373—around 14 per cent of the student body.The results of the poll, which is non-binding, will be discussed and voted on in OUSU’s 1st week Michaelmas Council.The motion was proposed by Wadham students, Matilda Agace and Isobel Cockbur. Writing in Cherwell, Agace, Cockbur and Taisie Tsikas claimed that “the hierarchical gown structure is fundamentally in conflict with ideals of community and equality that the University espouses”. “Many students are made to feel uncomfortable and nervous by the presence of a visual reminder of what they might perceive as their academic inferiority,” they wrote.It was further suggested that scholars’ gowns, which cost £45, do not accurately represent academic achievement. An argument in favour of the motion on OUSU’s website argued: “prelims results are more of a reflection of a student’s educational background than their grade in Finals”.However, there has been strong opposition to the banning of scholars gowns. Writing in Cherwell, Thomas Munro said that it would be “perverse to deny those who have achieved academically the rewards of their success”.Munro further argued: “to remove the right to wear [scholars’ gowns] from those who have already achieved scholarships reeks of envy, rather than any real desire for reform”.It remains unclear if the poll will prove decisive on this contentious issue. Because the consultation was solely advisory, OUSU council could still technically vote to adopt the policy of opposing differential gowns in examinations in October.last_img read more

Students help groups to pursue climate action

first_imgHow could preserving forests in Alaska or reducing nitrogen fertilizer runoff on farms in the Midwest help an organization interested in mitigating climate impact?This was one of the questions posed to diverse teams of graduate students brought together as part of the new, multidisciplinary “Climate Solutions Living Lab” course launched by Harvard University last spring to help push forward the transition to a carbon-free future that supports planetary and human health.Led by Wendy Jacobs, the Emmett Clinical Professor of Environmental Law and director of the Emmett Environmental Law and Policy Clinic at Harvard Law School, and developed in collaboration with the Harvard Office for Sustainability, the three-year research and teaching project was funded by the University as part of its living lab initiative to use the campus as a test bed for innovative sustainability solutions that can then be replicated across much broader levels.“No single professional discipline can tackle climate change in isolation; collaboration is critical,” said Jacobs. “We designed this course to address real-world challenges faced by climate leaders who are interested in investing in off-site emissions-reduction projects that can be proven to deliver environmental and social benefit.”The course’s outcomes are expected to offer Harvard clear strategies for how it can most effectively pursue high-quality, off-site emissions projects in the short term as part of the University’s longstanding commitment to modeling how organizations can dramatically reduce the climate impact of their operations. These same strategies, says Jacobs, can be implemented by other organizations.The use of carbon offsets or renewable energy investments to complement emissions reductions achieved on-site is becoming a necessary step for businesses and organizations that need to meet the ambitious carbon neutrality goals they have set. As demand has grown, a wide array of products are being offered to entities that wish to claim credit for the emissions reduction associated with a specific action or project.A 2015 advisory group of faculty experts convened by Harvard President Drew Faust to explore the topic found that while the markets for these off-site mechanisms are volatile and some products did not reliably result in additional emissions reductions, they are expected to mature in the coming decades. The group said that Harvard could play a role in developing the marketplace by promoting transparency and researching a range of options for high-quality offsets.“Increasing demand for clean-energy solutions from socially responsible companies and institutions will result in accelerated private-sector investment in energy innovation and the rapid deployment of new technologies,” said Rebecca Henderson, the John and Natty McArthur University Professor at Harvard Business School. “It’s critically important that Harvard, as a leader in the higher-education sector, play a role in contributing to this demand and spurring the creation of new climate-friendly solutions.”“Climate Solutions Living Lab” addresses these challenges by immersing cross-disciplinary teams of students in hands-on research to design feasible, practical, scalable projects for reducing at least 50,000 metric tons of greenhouse gas emissions annually, while allowing nonprofit and for-profit organizations to legitimately claim credit for those emissions reductions as offsets. The teams were also asked to minimize project costs while maximizing health, social, and economic benefits. Each team presented its final project proposal to a group of faculty and other experts for questions and feedback.One team, composed of six graduate students representing business, public health, design, law, and policy, visited Anchorage, Alaska, for a week while developing a plan for reducing emissions through preserving 150,000 acres of forest land owned by a native village. In a unique twist, the team suggested a small fee be added to the transaction that would support a social-impact fund to support the local economy and create jobs by implementing energy-efficiency upgrades in the homes of native residents who live adjacent to the forest.“Working in Alaska in particular, where renewable energy has a deep relationship to community development, showed how quite abstract phenomena like carbon-offset pricing have real impact on the everyday life of people,” said Harvard Graduate School of Design (GSD) alumnus Michael Haggerty, who graduated in May. “The course was a lesson in why we have 10 graduate Schools at Harvard in the first place, and how integrating the skills and knowledge of students from across the institution is essential for creating solutions to climate change.”Another team of three students representing the Schools of engineering, law, and public health designed a project to pay farmers to reduce their use of nitrogen-based fertilizers. Nitrous oxide is a potent greenhouse gas that remains largely unaddressed. Fertilizers represent a major source of nitrous oxide emissions.This team’s presentation attracted the attention of national farming groups because even though the carbon offset market recognizes the effectiveness of nitrogen reduction strategies and has approved their use to claim carbon credits, few effective demonstration projects have been developed to date.“The science behind a nitrogen fertilizer emissions-reduction strategy is already solid, but the challenge was developing an economical and practical implementation plan that could transform the concept into a feasible project,” said Harvard Law School student Chaz Kelsh. “Doing so required combining the skills that each student brought to class from our own disciplines.”Two other student teams explored projects that would allow a business or other organization to claim credit for the emissions reduced by implementing energy-efficiency measures in Rhode Island public schools, and by creating a revolving investment fund for investing in regional renewable-energy projects.All of the students reported that one of the most productive learning experiences they had in the course involved working across the boundaries of disciplines with students outside their areas of expertise and knowledge.“As we exchanged expertise and forced each other outside of our respective silos, we began to learn the language of one another’s disciplines,” said Caroline Lauer, a GSD student who worked on the Alaska project. “Our different perspectives sometimes clashed, and throughout the semester we navigated those conflicts and negotiated trade-offs within our group. We were each forced to define our values and advocate fiercely for them.”“Climate Solutions Living Lab” is now accepting applications for the spring semester. The deadline to apply is Nov. 30.last_img read more

A revolutionary musical

first_img All the world’s a stage Related Inspired by Cairo Radcliffe fellow sees reflections of Arab Spring in comic art revolutioncenter_img Love. Music. Freedom. These are the universal themes at the heart of “We Live in Cairo,” a new musical by Daniel and Patrick Lazour, which is having its world premiere at the American Repertory Theater. Set during the January 25 Revolution, the 2011 uprising in Egypt, the work, under the music direction of Madeline Smith and music supervision of Michael Starobin, celebrates the hope and exuberance of the uprising, even as it acknowledges the turmoil that has followed.The brainchild of the Lazours, brothers of Lebanese descent who began writing musicals together in their early teens, “We Live in Cairo” focuses on six young people at the heart of the protests that filled that city’s Tahrir Square with music and cries of “Bread, freedom, and social justice,” ultimately bringing down the regime of President Hosni Mubarak. As the production, which is directed by Taibi Magar and choreographed by Samar Haddad King, went into its final rehearsals, the Gazette sat down with the brothers and Tarek Masoud. Masoud, who served as a consultant on the project, is the Sultan of Oman Professor of International Relations at the Harvard Kennedy School  and the son of Egyptian immigrants.Masoud’s perspective is useful, say the brothers, because he provides a scholar’s frame of reference. He will speak after the 2 p.m. performance on June 1 as part of a series of post-show discussions called Act II.Daniel Lazour said that when the project began in 2013, “We were just really taken with the jubilation of 2011.” He cited the rapid growth of the uprising, which drew “a million people in Tahrir Square during the 18 days” of protest.Like those protesters, the brothers were enthralled by the possibilities of the Arab Spring, which had begun a month earlier in Tunisia. “These characters are dealing with hopes and dreams about a secular government and a government of democracy, a government where they can express themselves fully and freely,” said Patrick Lazour. In this context, he said, a musical made perfect sense. “This revolution was truly a moment for the artists of Egypt and to express themselves.”“That’s where the narrative sort of ended for our first draft,” said Daniel. “We were like, isn’t this great? As things started unfolding post-revolution, we realized that the story needed to encapsulate that as well.”,Understanding the aftermath — in which current Egyptian President Abdel Fattah el-Sisi has consolidated power through the military — was problematic. Although the brothers were able to workshop their musical at the American University in Cairo a year and a half ago, for example, what they heard varied greatly, depending on the age of the respondents. “Some were old enough to have been there,” recalled Patrick. Other students, who had been too young to be directly involved, were “sort of seeing it through a different lens,” he said.His brother summed up the experience: “There’s no historical record to agree upon because there isn’t a historical record that’s allowed to exist.”“There is an enormous amount of disagreement about what the January 25 Revolution really was and who owns it,” said Masoud, the co-author of “The Arab Spring: Pathways of Repression and Reform.”“If you were to open up the constitution of Egypt, that is today being amended in order to allow Egypt’s current president to persist in office until 2030, you would see encomia to the January 25 Revolution — even though many people would view the current regime as being the exact opposite of what the January 25 Revolution was about.”For example, although the protesters sought the end of repressive state controls, Masoud points out, “You will see often military officers or police officers with ribbons commemorating the January 25 Revolution.“This is an event in Egypt that everybody has agreed is legitimate. But everybody uses [it] for their own ends.”,Overall, the professor praises the playwrights for their success in depicting such a complex situation. “They got all the important things right,” said Masoud, an unabashed fan of musicals. In particular, he cites “the incredible spirit of possibility that attended the revolution.”“You’ve got to remember Egypt was a place that everybody thought was totally stagnant,” he said. “So when [the revolution] did happen, our jaws just dropped. It was indescribably inspiring.”Although subsequent events have been dispiriting, with el-Sisi’s regime assuming many characteristics of Mubarak’s, Masoud credits the brothers with reviving that earlier sense of optimism. “I had gotten quite jaded about the revolution,” he recalled. “Hearing their music I have all those feelings once again. So they were able to somehow capture that spirit of possibility and make me remember it. To me, that is the most amazing thing about this play.”“And that’s what ‘We Live in Cairo’ reminds us of as well,” said Daniel Lazour. “By helping us recapture that moment of potential, it reminds us that none of that stuff went away. Those people are still around. These yearnings are universal — yearnings that got people to risk their lives and livelihoods in order to demand something better. That’s still there. That didn’t go away. And so that possibility that existed may still exist. And if you leave the theater with just that thought, I think that’s pretty remarkable.”American Repertory Theater (A.R.T.) at Harvard University, the Ash Center for Democratic Governance and Innovation, and the Belfer Center’s Middle East Initiative at Harvard Kennedy School will co-present the Act II Speaker Series, discussions with leading artists, journalists, and scholars in conjunction with A.R.T.’s production of “We Live in Cairo” on topics inspired by the show.

Malverne Police Chief Supports NY Gun Control Law

first_imgSign up for our COVID-19 newsletter to stay up-to-date on the latest coronavirus news throughout New York Malverne Police Chief John Aresta on Fox Business NewsMalverne Village chief of police John Aresta, whose uncle was gunned down in the 1993 Long Island Rail Road Massacre, told Fox Business News on Wednesday that he supports gun control laws for personal reasons and because of his position as the village’s top cop.WATCH ARESTA’S INTERVIEW HERE“I send my guys out there everyday to protect and serve the people of my village and the state of New York,” he told the show’s host one day after New York Gov. Andrew Cuomo’s gun control legislation was passed by the state legislature. “We don’t see a reason, and I personally don’t see a reason why anybody would need a 30-round clip or a 10-round clip for an assault rifle.”The state’s new gun control measures calls for a ban on assault weapons and any magazine that can hold more than seven rounds. It also looks to limit the access of guns to the mentally ill by requiring therapists to report to local mental health officials when they believe a patient may cause serious harm to themselves or others.When Aresta was asked if this law would have prevented the shooting, he said it’s possible, though conceded that nothing is guaranteed.“It’s very possible [Colin] Ferguson would’ve been picked up on a mental health issue,” Aresta said.The semi-automatic handgun Ferguson used in the shooting does not fall under the state ban, but “the magazine clip he used would have been,” Aresta said.He then added that he’s talked to his officers, many of whom are NRA members, and said even they don’t see the need for assault weapons. When he asked them if they know anybody that goes hunting with an AR-15, they responded, “nobody really does,” Aresta noted.Critics of New York’s assault weapon ban and the one proposed by President Barack Obama said it won’t curtail gun violence because most gun crimes are carried out with handguns. The police chief also admitted that the village doesn’t see many assault weapons crimes in the village.Still, he said, “I don’t see a reason why you would have to defend your home like that when police are readily available,” referring to assault weapons because his officers can respond to a 911 call within minutes.The LIRR shooting on Dec. 7, 1993 claimed the lives of six people and wounded 19.last_img read more

U.S. officials warn of challenges administering Eli Lilly’s antibody drug

first_imgIn this May 2020 photo provided by Eli Lilly, researchers prepare mammalian cells to produce possible COVID-19 antibodies for testing in a laboratory in Indianapolis.David Morrison | Eli Lilly via AP States and local health-care systems should expect to face some early challenges administering Eli Lilly‘s coronavirus antibody drug, senior administration officials warned Tuesday, after the FDA authorized the drug to treat patients with Covid-19.Eli Lilly’s drug, similar to the one given to President Donald Trump after he contracted the virus last month, is administered to Covid-19 patients via an IV infusion that takes more than an hour and requires another hour of observation afterward, officials said. That may be difficult in certain health-care settings, and Eli Lilly and the U.S. government are developing “playbooks” to help states navigate the process, said Dr. Janet Woodcock, director of FDA’s Center for Drug Evaluation and Research.“We anticipate that initially there’ll be challenges for the health-care system in administering IV infusions to infected patients,” Woodcock said on a conference call with reporters. “There are probably going to be multiple different solutions depending on the setting, [like] community health centers, home IV, health infusion companies, nursing homes.”- Advertisement – – Advertisement – The Food and Drug Administration on Monday authorized the treatment, called bamlanivimab, for people newly infected with Covid-19 and who are seen as at risk of developing a severe form of the disease. Officials said the treatment shouldn’t be used to treat patients who are hospitalized as there is currently no data to show the drug is helpful at that stage of the disease.The drug will “likely work best early in the disease and the goal during this [emergency use authorization] should be to treat high-risk individuals as soon as possible after they have symptoms and are diagnosed,” Woodcock said. “The data we have suggests that early treatment may help people avoid disease progression and avoid hospitalization.”“We’re all going to need to get the word out that people at high risk have a therapeutic option now .. Because until this point, people have been told to stay at home unless they get very sick,” she added.- Advertisement –center_img Health and Human Services Secretary Alex Azar said the U.S. government, through Operation Warp Speed, will begin distribution of the drug this week. Allocation of the drug will be based on states’ and territories’ share of the country’s total number of confirmed Covid-19 patients and the total number of confirmed hospitalized patients in a given week, he said. The drug will be distributed in two phases, with hospitals and hospital-affiliated locations getting it first, followed by outpatient centers.Health-care facilities must have the appropriate staffing, training and equipment to accommodate an IV infusion, according to Dr. John Redd, chief medical officer for the Office of the Assistant Secretary for Preparedness and Response within the U.S. Department of Health and Human Services.“We have a contract to purchase 300,000 doses of this product through December with the option to purchase another 650,000 doses through next June as well,” Azar said. “There are over 80,000 doses available for allocation and distribution this week, and we’ll be working with state, local and territorial health departments so that patients can receive the infusion in hospitals, outpatient clinics or alternate care settings.”Eli Lilly’s drug is part of a class of treatments known as monoclonal antibodies, which are made to act as immune cells that scientists hope can prevent the virus from infecting cells. A recent study in the New England Journal of Medicine found 1.6% of trial participants who received Eli Lilly’s antibody treatment ended up hospitalized or had a coronavirus-related visit to the emergency room, compared with 6.3% of people who received the placebo.Eli Lilly Chairman and CEO Dave Ricks told CNBC earlier in the day that the company’s antibody drug will still be an important treatment for Covid-19, even if a widely available vaccine is brought to market.Even in well-controlled [other] respiratory illness … we still have vaccination and antibody therapy because some patients escape the vaccine and still get the condition, and they need to be managed with a therapy,” he added. “This will be useful in the long term, hopefully at much lower volumes” in fighting Covid-19 as well.–CNBC’s Kevin Stankiewicz contributed to this report. – Advertisement –last_img read more
