Observational evidence of the influence of Antarctic stratospheric ozone variability on middle atmosphere dynamics

first_imgModeling results have suggested that the circulation of the stratosphere and mesosphere in spring is strongly affected by the perturbations in heating induced by the Antarctic ozone hole. Here using both mesospheric MF radar wind observations from Rothera Antarctica (67°S, 68°W) as well as stratospheric analysis data, we present observational evidence that the stratospheric and mesospheric wind strengths are highly anti-correlated, and show their largest variability in November. We find that these changes are related to the total amount of ozone loss that occurs during the Antarctic spring ozone hole and particularly with the ozone gradients that develop between 57.5°S and 77.5°S. The results show that with increasing ozone loss during spring, winter conditions in the stratosphere and mesosphere persist longer into the summer. These results are discussed in the light of observations of the onset and duration of the Antarctic polar mesospheric cloud seasonlast_img read more

‘Wahoo bursary’ rejected by Hertford JCR

first_imgRising prices at Wahoo have prompted a unique motion in the Hertford JCR to reimburse some of the cost of Hertford students’ drinks after nights out at the club.Hertford student Omer Sheikh Mohamed proposed on Sunday that the Hertford JCR “reimburse students 50p for every double vodka Red Bull bought in Wahoo upon presenting a receipt to the JCR Treasurer”.The beverage in question has recently increased in price from £2 to £2.50 at Wahoo, while entry costs have risen to £4. Sheikh Mohamed’s motion claimed that, “Wahoo is Hertford’s favourite night out”, and added that the price increases might discourage freshers from frequenting the club and harm the “access work and inclusivity” on which the college prides itself.After an amendment to the motion, which compelled the JCR President to write to the manager of Wahoo “in opposition to the price increases”, subsidy-seekers’ hopes were dashed when the motion fell 16-22 in a vote at the Hertford JCR meeting. Those against the motion included JCR President Hugh Baker and JCR Treasurer Bhavin Patel, who allegedly dismissed it as “obviously a joke” during the course of the meeting.English student Siobhan Dunlop was also against the motion. She said, “I am a finalist, so the closest I get to Wahoo is hearing freshers talk about it in the Tesco queue. When I read about the motion in the JCR e-mail, I had to do a double take. Seriously, I am staggered that anyone would believe in their ‘hert’ it is a useful way to spend JCR money.”Yet Hertford students may not have to worry about affording their Friday nights in any case. Toby Beers-Baker, CEO of Shuffle Nights, clarified that the 50p rise in the price of a double vodka Red Bull only applies after 11pm. He told Cherwell, “Given the extremely high prices of rent and overheads in Oxford, we feel we do give extremely reasonable deals to students.”He went on to note that on non-student nights, a double vodka Red Bull costs £6. He said, “We are providing student prices on a Friday – something competing venues do not do. There is also a fantastic atmosphere at Wahoo on a Friday due to the popularity and clientele of the night.”When asked to justify the rise in prices, Beers-Baker cited expensive improvements to Wahoo, which include a new sound system, lighting rig, and dance podium.last_img read more

Food that’s better for all of us and the planet

first_img ‘Farming While Black’ author looks at barriers faced by people of color University signs Cool Food Pledge, vowing a 25% improvement by 2030 Leading the fight for food justice How to feed 10 billion by midcentury Harvard to cut food-related greenhouse gas emissions Forget the food pyramid, or even the FDA’s more recent ChooseMyPlate initiative, aimed at getting Americans to eat healthier. If our species and our planet are to survive, humanity needs to refocus on a diet that encompasses not only fruits and vegetables but also sustainability and social justice, according to participants at a wide-ranging summit on food production, diet, and sustainability in Boston on Wednesday.Called “Food, Farms, Fisheries, and Forests,” the daylong event at the University of Massachusetts Club was presented by the American Farmland Trust and Harvard Pilgrim Health Care Foundation, in partnership with the Harvard T.H. Chan School of Public Health, Harvard Forest, Harvard Law School, Harvard Kennedy School, and Food Solutions New England. The purpose was to bring together experts on the environment and nutrition as well as people focused on social justice and its implications for feeding the population.Walter Willett, M.P.H. ’73, Dr.P.H. ’80, opened the discussion by outlining the dangers posed by a business-as-usual approach. Willett, professor of epidemiology and nutrition at the T.H. Chan School of Public Health and professor of medicine at Harvard Medical School, said the global community faces the challenge of feeding a population expected to hit 9.8 billion by 2050. Those findings emerged from the international EAT-Lancet Commission on Food, Planet, Health he chaired over the past three years.“The standard response is to increase food production,” Willett said. But simply producing more food may not be the best idea, as there is strong evidence that our current diet is killing us. “Obviously and conspicuously, obesity is increasing” in both adults and children, Willett noted. The results include more obesity-related cancers and heart disease. “In three out of the last five years, life expectancy in the United States has fallen,” he noted. “Life expectancy has decreased for two years in a row.” (Slight increases were noted in 2018 and 2019.)In addition, global warming ­­— to which food production is a major contributor — is accelerating, and resources, including water, are threatened. This led to a challenge, said Willett, “to apply a global-food-systems framework to see if optimal diets could fit within planetary boundaries.”The resulting Planetary Health Diet resembles current recommendations by leaning heavily on fruits and vegetables. Where it differs, Willett said, is in protein sources. “Red meat is a real outlier in terms of greenhouse-gas production,” he said. Citing “major implications for health and the environment,” this plan recommends one serving of dairy a day, a modest amount of poultry and eggs, and, at most, one serving of red meat a week, with legumes, nuts, and whole grains making up the rest. “There’s some flexibility around this,” he said. “Different cultures will want different mixes.” “Earth has been a self-regulating and self-sustaining system. We need to bring nature back to the fore and allow it to help us.” — David Foster, director of the Harvard Forestcenter_img The proposed diet, at least half plant-based, would go a long way toward curbing American obesity rates. Perhaps more importantly, it would ultimately improve the health of everyone on the planet. “We are on a path to a sustainable ecological system,” he said. Speaking later in the morning, Brandeis University Associate Professor of Environmental Studies Brian Donohue summed up the goal: “The Planetary Health Diet links the public health benefits of healthy food with the planetary benefits of lowering our carbon footprint.” Focusing specifically on New England, ecologist David Foster, director of the Harvard Forest, talked about balance. “Earth has been a self-regulating and self-sustaining system,” he said. “We need to bring nature back to the fore and allow it to help us.”These efforts should begin locally, he stressed. “We talk about the Brazilian rainforest,” he said. “But here in New England we are losing 24,000 acres of forest every year,” with trees cleared for housing and commercial space or cut for energy or other uses. “We desperately need to reduce our resource consumption,” he said, citing personal discipline as a “fundamental step.”New England already has the framework, with 65 percent of it already at least partly covered by conservation partnerships, Foster said. Beyond that, he discussed planting trees and bringing nature — in the form of urban gardens and wild spaces — into communities that may feel detached. “There’s a lot we can do individually in our work, in our communities, in the organizations we are part of,” he said, presenting a vision that would “increased protect forest, strategically grow housing, and retain our farmland.”“The best place in the world to look for some lessons is here in New England,” said Foster. “Nature, if allowed, will recover, will restore itself and will begin to produce.”Other speakers throughout the day, including Naima Penniman, program director of Soul Fire Farm in New York and S. Atyia Martin, CEO and founder of Boston-based All Aces, Inc., discussed such topics as the historical and racial roots of food inequality, from “food deserts” to unsustainable and unjust policies of land theft by early settlers. Both also discussed how initiatives are helping underserved communities reclaim agency in terms of health and nutrition, as well as stewardship of the land.

Fundraiser Launched For Family Farm Destroyed By Tornado

first_imgOn Friday, the National Weather Service classified Thursday’s tornado as an EF1.Meteorologists say a funnel cloud developed on the south side of Barnes Road and the Tornado’s initial touchdown occurred in a wooded area near a farm then moved across the property around 4:50 p.m.Overall, the storm produced maximum winds up to 100 miles per hour and was on the ground for a total of one and a half miles. Image by Shawn Sweatman / Chautauqua Weather Today. PORTLAND – A GoFundMe page is collecting donations for a family whose farm was destroyed by a tornado in Chautauqua County this week.Sarah Sprague launched the fundraiser for the Marczynski family farm on Barnes Road.“The house got away with very minor damage, but the barn, the workshop, and most of the fencing for the pasture has been destroyed,” said Sprague. “Their vehicle is totaled, as well as significant other trucks.”Sprague says all the horses, goats and cows are accounted for with few superficial injuries. However, she says some of the birds on the farm died in the storm.“The amount of hay and feed that was damaged and lost due to the storm is huge,” explained Sprague. “Machinery is damaged and/or totaled. The barn is pretty much a complete loss. It’s just devastating. That’s the only way I can describe it.”Since Saturday morning, the fundraiser has raised over $1,000 with a goal of $5,000.center_img Share:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to email this to a friend (Opens in new window)last_img read more

School Gardens

first_imgThe number of school gardens is on the rise as Georgia teachers search for engaging ways to educate students about their food.School gardens are also gaining momentum because they help teachers meet science, technology, engineering, arts and mathematics (STEAM) education requirements, according to Becky Griffin, community and school garden coordinator for University of Georgia Cooperative Extension.“You use a lot of division and recording to plant a garden, and some teachers have students grow their crops in geometric shapes,” Griffin said.English teachers may have their students read a book and then plant the crops or flowers that the book mentions, Griffin said. History teachers have their students plant colonial gardens filled with crops that might’ve been on first President George Washington’s dinner table.School gardens are an excellent educational tool, but they are also a lot of hard work. To be successful, the garden project has to be supported by the school board, teachers, parents and community leaders.“If the garden is being planned and planted by just one teacher, it’s going to fail,” Griffin said. In Dougherty County, Georgia, UGA Extension agent James Morgan has helped to establish gardens in 13 of the county’s 14 elementary schools. Morgan’s gardens have won Golden Radish Awards, an honor presented annually to schools where teachers and personnel are doing extraordinary work in terms of farm-to-school programs. The award is presented by the Georgia Department of Education, Georgia Department of Agriculture, Georgia Department of Public Health, Georgia Organics and UGA Extension. To date, Morgan’s gardens have earned two gold radishes, along with a silver and a bronze.“These school gardens would not be successful if not for the buy-in from the principals and school liaisons,” Morgan said. “And the gardens wouldn’t be possible without the support of our teaching garden planning team.”The planning team meets each fall to begin planning the gardens. Team members are then assigned to schools, where they meet with the principal and the school’s garden liaison.“First, we have to see if weeding needs to be done, if wood for beds needs replacing or if soil needs to be added,” Morgan said. “The liaison then works with the kids or volunteers to weed the beds. During this time, we place an order for transplants and schedule soil drop-off and planting times.”Each garden has seven raised beds where students grow lettuce, collards, kale, spinach, scallions and radishes. After planting, the planning team and students monitor the school gardens throughout the growing season. “In the event of cold weather, I have someone in the school nutrition office send out an email to all the liaisons letting them know how to protect the plants from cold weather,” Morgan said.As the plants get close to maturity, Morgan visits the schools and shows the students when to harvest the radishes or how to harvest the leaves from the leafy vegetables so that the plant will continue to produce more leaves. When the students harvest their vegetables, the school cafeteria staff incorporates them into each school’s holiday lunch, he said.Team member organizations include Southwest Georgia Master Gardener Extension Volunteers, UGA Extension, Phoebe Putney Memorial Hospital, Southwest Georgia Project, Dougherty County Farm Bureau, City of Albany Recreation and Parks Department, Dougherty County Child Nutrition Program, and Georgia Region V Soil and Water Conservation District.To help Georgia teachers with school gardens, UGA Extension and the Georgia Center for Urban Agriculture offer training for teachers. At the training sessions, teachers learn about selecting crops that are in season during the school year, testing garden soil before planting, composting, attracting beneficial insects and controlling pests using a minimal amount of pesticides. Since 2015, 150 teachers have been trained at workshops held in Athens, Atlanta and Griffin, Georgia.For more information on this program, visit ugaurbanag.com/gardens/teacher-training.last_img read more

Coal Production in Uinta Basin of Colorado and Utah Drops by 34.7%

first_imgCoal Production in Uinta Basin of Colorado and Utah Drops by 34.7% FacebookTwitterLinkedInEmailPrint分享Christopher Coats for SNL:Coal production at mines in the Uinta Basin continued to slide in the first quarter of the year, down nearly 900,000 tons from the previous period and 34.7% below the same period in 2015.For the 12 months ending with the first quarter of the year, basin output was 29.3 million tons, down about 26.5% from the same period last year.This quarter’s results continue a production slide that has plagued the western region, along with others, with Uinta mine output down nearly 3 million tons from the first quarter of 2015, according to an S&P Global Market Intelligence analysis of U.S. Mine Safety and Health Administration data.One of the most significant drops in production from the first quarter of last year came at Arch Coal Inc.’s West Elk mine in Colorado, where output collapsed nearly 650,000 tons from 2015 to 521,527 tons in the latest period. Mine owner Arch Coal filed for bankruptcy protection during the first quarter, though the company has previously reported that it intends to continue production efforts during its restructuring.The basin’s largest drop for the 12-month period was seen at Bowie’s No. 2 mine, which finished the period down about 82%.

Number of Renewable Energy Jobs Tops 10 Million

first_img FacebookTwitterLinkedInEmailPrint分享CNBC:Over 500,000 new jobs were generated by the renewable energy industry last year, a 5.3 percent rise when compared to 2016, according to a report.The number of people working in the renewable energy sector—including large hydropower—hit 10.3 million in 2017, the International Renewable Energy Agency (IRENA) study said.The world’s biggest renewable energy employers were China, Brazil, the U.S., India, Germany and Japan. Altogether, these countries represented over 70 percent of jobs in the industry globally.Breaking the figures down, IRENA said that the solar photovoltaic industry employed the largest amount of people, with almost 3.4 million working in that sector. China remained a solar powerhouse, and accounted for an estimated two-thirds of solar PV jobs, or 2.2 million.In the wind energy sector, IRENA noted a slight contraction in the market last year, with 1.15 million jobs recorded. China again led the way, accounting for 44 percent of employment.More: Jobs In Renewable Energy Hit 10.3 Million Last Year, Report Finds Number of Renewable Energy Jobs Tops 10 Millionlast_img read more

Monitoring kids’ social media won’t stop next shooting

first_imgA WASTED EFFORT?There is little evidence that such monitoring works, and these practices raise plenty of questions about privacy and discrimination.Nikolas Cruz, the suspected perpetrator of the Parkland shooting, hardly presents a case for schools to proactively check social media.If anything, it shows that people already alert law enforcement when they see genuinely threatening material online.Cruz was reported to the FBI and local police at least three times for disturbing posts; one call to the FBI warned that he might become a school shooter, while a separate call flagged a YouTube post saying that the user wanted to become a “professional school shooter” (although the poster wasn’t identified as Cruz until after the shooting).And Cruz’s explicit declaration of intent is the exception, not the rule, which means monitoring the Internet wouldn’t usually turn up such warnings.Our informal survey of major school shootings since the 2012 Sandy Hook killings in Newtown, Connecticut, shows that only one other perpetrator’s social media accounts indicated an interest in school violence: Adam Lanza.Lanza, the Newtown shooter, posted in discussion forums about the Columbine high school shooting and operated Tumblr accounts named after school shooters. These postings were not a secret, and while viewers at the time may not have known whether to take the threats seriously, it is hard to imagine in the current climate that his posts would not be reported to the authorities — as they should be.Generally, school shooters’ online profiles — which wind up being extensively analyzed in the wake of attacks — reveal little that sets them apart from other teenagers.An algorithm trawling the Web for people who like violent video games or firearms would be swamped with far more hits than any law enforcement agency or school administrator could conceivably review.The same would be true of any program that looked for words like “gun,” “bomb” or “shoot,” as the Jacksonville, Florida, police department discovered the hard way when its social media monitoring tool — while producing zero evidence of criminal activity — flagged comments about crab burgers, pizza or beer being described as “bomb,” or excellent. (It also caught two uses of the phrase “photo bomb.”)DISCRIMINATION EVIDENTSocial media monitoring tools can also result in discrimination against minority students.A recent ACLU report showed that the Boston Police Department’s social media monitoring efforts contributed nothing to public safety while searching for terms like “Ferguson” and “#blacklivesmatter,” as well as terms likely to be used by Muslim users, like “#muslimlivesmatter” and “ummah,” the Arabic word for community.There is also substantial evidence to suggest that children of color, especially those who are Muslim, would be treated as dangerous and perhaps subject to extra monitoring, despite the fact that the majority of school shooters have been white. Categories: Editorial, OpinionThe Parkland, Florida, school shooting has reignited the national conversation on what can be done to prevent such tragedies, which seem to occur with frightening regularity.One option, which already is used by many schools and probably will be adopted by more, is to employ companies that monitor students’ social media feeds to flag threats of violence, as well as behavior such as bullying and self-harm.Miami-Dade County’s school system has asked for $30 million in upgrades that include “advanced monitoring of social media,” while schools in California, Ohio, Tennessee and Virginia have indicated that social media monitoring, including by third-party companies, is a key security feature.But schools should think long and hard before they go down this path.  Children of color appear likely to be treated more harshly in general, even when their white peers break the same rules.KIDS MAY GET SNEAKIERAs many Americans cheer the Parkland shooting survivors for their political activism, it is important to recognize the chilling effect of ongoing surveillance.Given that 92 percent of American teens go online daily and 24 percent are online almost constantly, monitoring programs can operate like listening devices that record every utterance and pass it on to school administrators.Yes, this scrutiny may on occasion reveal risky behavior that requires intervention.But far more often, it will also squelch young people’s ability to express themselves — and probably drive conversations to communications channels that cannot be easily monitored.POLICIES NEEDEDThis is not to say that schools should never look at students’ Facebook posts.But they should generally do so only when there is a reason — for example, when a student or parent has flagged concerning behavior or when the school is investigating online harassment or bullying. Every school must have in place policies available to parents, teachers and students specifying when it will look at social media postings.Such policies should be narrowly tailored to avoid impinging on the privacy and free speech rights of students, and they should limit the sharing of data with third parties and include procedures for deleting information when a child graduates or leaves the school, as well as safeguards to ensure that children of color are not unfairly targeted.In the wake of yet another school shooting, Americans are understandably looking for ways to keep students safe.We should focus our attention on measures that have been proved to work, such as sensible gun controls and ensuring that parents and peers know whom to contact to report threats and to receive help, rather than expensive tools that are unlikely to make us secure but carry substantial costs for the very children we are trying to protect.Faiza Patel is co-director of the liberty and national security program at the Brennan Center for Justice at New York University.Rachel Levinson-Waldman is senior counsel in the liberty and national security program at the Brennan Center for Justice at NYU School of Law.More from The Daily Gazette:EDITORIAL: Urgent: Today is the last day to complete the censusEDITORIAL: Find a way to get family members into nursing homesEDITORIAL: Beware of voter intimidationEDITORIAL: Thruway tax unfair to working motoristsFoss: Should main downtown branch of the Schenectady County Public Library reopen?last_img read more
