Credits: Pond5As the coronavirus pandemic slowed global commerce to a crawl in early 2020, emissions of nitrogen oxides — which create ozone, a danger to human health and climate — decreased 15% globally, with local reductions as high as 50%, according to a study published today, led by scientists at Pasadena’s Jet Propulsion Laboratory.As a result of the lower NOx emissions, by June 2020 global ozone levels had dropped to a level that policymakers thought would take at least 15 years to reach by conventional means, such as regulations.The study shows that innovative technologies and other solutions intended to decrease NOx locally have the potential to rapidly improve air quality and climate globally. It was published Wednesday in Science Advances.Ozone protects us from destructive solar radiation when it’s high above Earth in the stratosphere. Closer to the ground, though, it has other lasting impacts. Ozone at the surface was estimated to cause 365,000 deaths globally in 2019 by damaging the lungs of vulnerable people, such as young children and those with asthma. Similarly, it damages the breathing systems of plants — their ability to photosynthesize — reducing plant growth and crop yields. And at the top of the troposphere, it’s a potent greenhouse gas, increasing global temperatures.When the world went into lockdown, scientists had an unprecedented opportunity to study how human activity interacts with natural Earth system processes at regional and global scales. A team of international researchers led by JPL scientist Kazuyuki Miyazaki used this opportunity to research the two main oxides of nitrogen: nitrogen oxide and nitrogen dioxide, collectively called NOx. They charted the chain of events from reduced fossil fuel burning during lockdowns to reduced local NOx emissions and finally to reduced global tropospheric ozone pollution.The more stringent the lockdown a nation imposed, the greater the reduction in emissions. For example, China’s stay-at-home orders in early February 2020 produced a 50% drop in NOx emissions in some cities within a few weeks; most U.S. states achieved a 25% drop later in the spring.The total result of the reduced NOx emissions was a 2% drop in global ozone — half the amount that the most aggressive NOx emission controls considered by the Intergovernmental Panel on Climate Change, the authoritative body of international experts on climate, were expected to produce over a 30-year period.Ozone reductions from the reduced NOx emissions quickly spread both around the globe and from the surface upward more than six miles — 10 kilometers.“I was really surprised at how large the impact on global ozone was,” said JPL scientist Jessica Neu, a co-author of the new study. “We expected more of a local response at the surface.”The reactions that transform NOx into ozone require sunlight and depend on many additional factors, such as weather and other chemicals in the air. These factors interact in so many ways that, in some circumstances, reducing NOx emissions actually increases ozone. So researchers cannot fully understand or accurately predict ozone concentrations from NOx emissions data alone. That requires a more thorough analysis, like this study, Neu said.

Caution will control power of the e-mail

first_imgCaution will control power of the e-mailOn 27 Mar 2001 in Personnel Today Previous Article Next Article DavidTaylor offers guidance on putting in place a company e-mail policy that is fairto everybodyForgetthe dotcom hype, mobile technology and the Internet – the biggest growth areaof the new business age by far is e-mail, and this brings a huge opportunityfor HR leaders.E-mailsfeed our reactive, rather than responsive behaviour, often failing to make thepoints intended, and are too often used as an alternative to other means ofcontact. As one of the most public, powerful and prevalent forms ofcommunication, there is a need for caution, care and clarity and, once this isdone, it can be hugely positive.Youcan set a company trend in HR by doing the following:– Make e-mails friendly (write Dear name, and always end on a friendly note)– Use the term “we” rather than “you” and always put yourself in the place ofthe recipient – reading through what you have written before you send it– Ensure that the quality of e-mails we send is as good as those we receive.Itmay be time to put in place company guidance, covering the key issues:Information on other companiesTo avoid litigation do not use e-mail to discuss competitors, potentialacquisitions or mergers, or to give your opinion about another company. Theword confidential simply does not apply to electronic communication – somebodyelse in your organisation can always access it.Personale-mailsMany companies are concerned about the growing numbers of non-work relatedcorrespondence. The key words here are guidelines and trust. Put in place aclear policy that gives some freedom, but ensure staff know the boundaries ontime and content. Manage your staff by giving them ownership and responsibility.Aggressivee-mailsIt is one thing to misunderstand the sender’s intent, quite another todeliberately attack someone by e-mail. Business bullying is now recognised byindustrial tribunals as a form of illegal behaviour in itself.SexualharassmentThe cases of this, and stalking over e-mail, are growing. Company policymust be extended to include this area and should lead to dismissal. Encouragepeople to come forward with evidence and make it clear that all e-mails areheld on the mainframe or network after they have been written. This willdiscourage most people.Chaine-mailsThese are both unpleasant and destructive in terms of time, volume oftraffic on a network and personal well-being. Treat these seriously, root outtheir origins and invite recipients to send them to you.Electroniccommunications are no different from every other form and there should be noneed for complex guidelines, rules and restrictions. As long as everyone isclear on your company’s policy, none of these potential dangers will grow outof hand.

Report: No Player At February’s NFL Combine Failed Drug Test

first_imgAdam Schefter sits in front of his book case during ESPN appearance.SchefterVirtually every year during the NFL Draft process, a few high-profile prospects fail drug tests from February’s combine. That is, until 2016. According to ESPN’s Adam Schefter, not one player tested positive at this year’s event in Indianapolis, something that is almost unprecedented.For the first time in recent memory, NFL has notified all 32 teams that no player tested positive at February combine, per league sources.— Adam Schefter (@AdamSchefter) April 25, 2016No matter where you fall on the subject of recreational drug use, most would hope that a player can avoid failing a test that they know is coming at the combine. Almost every draft class has a few players fail and see their stock suffer, so congratulations to the class of 2016 for bucking that trend.last_img read more

Prince Charles And Joanna Lumley Honor Arts Philanthropists

first_imgThe Prince of Wales has honoured philanthropists for their dedication to supporting the arts.His Royal Highness presented medals at St James’s Palace in London to individuals who have backed the UK’s culture scene.Actress Joanna Lumley was master of ceremonies at the event in the Palace’s state apartments.Among those who received the 2014 Prince of Wales Arts Philanthropy Medal were Terry and Liz Bramall, from Harrogate, who are regarded as two of the country’s most generous philanthropists.Mr and Mrs Bramall placed more than £96 million into the Liz and Terry Bramall Foundation in 2008 after Mr Bramall became a building tycoon.The Foundation has made grants of around £2 million a year to organisations in Yorkshire, supporting Northern Ballet, Phoenix Dance and the West Yorkshire Playhouse.A former bus company boss turned philanthropist who donated millions to causes in the North East including the Sage Gateshead, Live Theatre and Tyneside Cinema was posthumously awarded the medal.Trevor Shears, who died from cancer in May this year, was part of the management buy-out that formed Newcastle transport firm Go Ahead in 1987. The company’s public flotation in the mid-1990s brought him immense wealth – but he gave more than half of it away.His wife Lyn was also honoured for the couple’s support of the arts.Mrs Shears said: “It’s vitally important to introduce more young people to the arts because they are the audiences of tomorrow. Some have a huge talent but don’t know how to use it.“One girl we met was a wonderful singer working in Tesco and following some tuition and confidence building with (music charity) Samling she is now at the Royal Academy of Music.“It’s hugely rewarding to make even a small difference. My husband and I always felt that we got so much more from the giving than the recipients did.“We never did it seeking recognition but it’s a huge honour to receive the medal from The Prince of Wales. It’s sad that Trevor can’t be here but I know he would have been immensely proud.”Other recipients were Sir Harry and Lady Carol Djanogly, who have helped the V&A, Tate and the Chickenshed theatre company; Lady Susie Sainsbury of Turville, deputy chair of the Royal Shakespeare Company; and John J Studzinski whose Genesis Foundation strives to nurture young talent.Source:www.princehenryofwales.orglast_img read more

Montreals port eyes another record year in 2018 for cargo and cruise

first_imgMONTREAL – The Port of Montreal started 2018 with hopes of another record year for cargo traffic as the Canadian free trade agreement with Europe begins to bear fruit.Canada’s second-largest port anticipates cargo traffic increasing about four per cent after ending 2017 up almost seven per cent at a record 38 million tonnes.A strong economy, growing business with Asia and reversal of Enbridge’s 9B pipeline contributed to last year’s strong results, port CEO Sylvie Vachon said Wednesday.“The fact that the economy will be stronger will be very positive for that kind of cargo,” she said in an interview.Last year marked the first full year of operations for a new container terminal that will eventually handle 600,000 twenty-foot equivalent units (TEUs) per year. The port is pushing for approval of another terminal that would accommodate 1.15 million TEU containers per year starting in 2021 or 2022.Vachon said U.S. President Donald Trump’s threat to end the North American Free Trade Agreement is prompting transporters to look at developing other markets, notably Europe because of the new trade deal.“It will be gradual but positive for us,” she said of the European trade agreement.The Port of Montreal is also coming off a record year for cruises with the anticipation of growing that business by another 14 per cent to 130,000 passengers in 2018. More than 50 ship arrivals brought more than 114,000 passengers to Montreal last year, up 33 per cent over 2016 and up 140 per cent compared with 2011.The growth resulted from more cruises stopping to mark Canada’s 150th birthday and the 375th birthday celebrations of Montreal’s founding and the cruise industry’s interest in adding new destinations.The preliminary traffic results were released at an event awarding a gold-headed cane to Capt. Rakesh Kumar of the container ship Ottawa Express. The cane has been given annually for 179 years to the first ocean-going vessel to reach the Port of Montreal without a stopover.Kumar said he’s docked in Montreal about 60 times, but never experienced the extreme cold weather that has gripped much of the continent in recent days.However, the frigid conditions haven’t hurt the port operations.“For sure for the people who work outside it’s difficult, but with the Coast Guard who do a very good job to break the ice, for the moment everything is OK for the Port of Montreal,” Vachon said.The same can’t be said for the St. Lawrence Seaway where ice on the U.S. side has caused five ocean vessels to remain in the Cornwall-to-Kingston area and will force the waterway to close a few days later than normal for the winter season.“Once we see those ships complete that portion of their transit they should be clear to finish the Canadian section and exit the St. Lawrence Seaway,” said Seaway spokesman Andrew Bogora.Although the final tally for St. Lawrence Seaway traffic is expected to be released next week, Bogora expects the momentum of the year was maintained in December. As of November, cargo traffic in the first 11 months of the year was up around 8.5 per cent.The growth was largely attributable to a 35 per cent increase in iron ore tonnes destined for Asia. General cargo was up 28 per cent and dry bulk 12 per cent. Grain was down 10.5 per cent.last_img read more

Child experts Just say no to Facebooks kids app

first_imgBOSTON – Child development experts and advocates are urging Facebook to pull the plug on its new messaging app aimed at kids.A group letter sent Tuesday to CEO Mark Zuckerberg argues that younger children — the app is intended for those under 13 — aren’t ready to have social media accounts, navigate the complexities of online relationships or protect their own privacy.Facebook launched the free Messenger Kids app in December, pitching it as a way for children to chat with family members and friends approved by parents. It doesn’t give kids separate Facebook or Messenger accounts. Rather, the app works as an extension of a parent’s account, and parents get controls such as the ability to decide who their kids can chat with.The social media giant has said it fills “a need for a messaging app that lets kids connect with people they love but also has the level of control parents want.” But critics see the move as a way for Facebook to lure in a younger audience before they could move on to a rival service such as Snapchat.“TARGETING YOUNGER CHILDREN”A group of 100 experts, advocates and parenting organizations is contesting Facebook’s claims of filling a need. Led by the Boston-based Campaign for a Commercial-Free Childhood, the group includes psychiatrists, pediatricians, educators and the children’s music singer Raffi Cavoukian.“Messenger Kids is not responding to a need — it is creating one,” the letter states. “It appeals primarily to children who otherwise would not have their own social media accounts.” Another passage criticized Facebook for “targeting younger children with a new product.”In a statement, Facebook said on Monday that the app “helps parents and children to chat in a safer way,” and emphasized that parents are “always in control” of their kids’ activity. The social media giant added that it consulted with parenting experts and families, and said “there is no advertising in Messenger Kids.”KIDS AND FACEBOOKA variety of experts and technology insiders have begun questioning the effects smartphones and social media apps are having on people’s health and mental well-being — whether kids, teens or adults. Sean Parker, Facebook’s first president, said late last year that the social media platform exploits “vulnerability in human psychology” to addict users. A chorus of other early employees and investors piled on with similar criticisms.Many preteens have already found their way onto Facebook and more youth-oriented social media platforms such as Snapchat and Facebook’s own Instagram, despite internal rules that require users to be at least 13 years old. Those rules are based in part on federal law, which prohibits internet companies from collecting personal information on children without their parents’ permission and imposes restrictions on advertising to them.Some companies have offered parental controls as a way of curbing unauthorized preteen use of their platforms. But Facebook’s new kid-focused app, which features animations and emojis, seems to cater to a younger audience, said Josh Golin, executive director of Campaign for a Commercial-Free Childhood.“It looks like something that would appeal to a 6-year-old or 7-year-old,” he said.He said the app gets those younger ones used to Facebook’s platform “and then they transition to the mature version of Facebook.”UNCERTAIN IMPACTFacebook wouldn’t answer questions about how popular the messaging app has been. But App Annie, an app analytics firm, said Messenger Kids has been downloaded about 80,000 times on Apple’s iOS devices — iPhones, iPads and the iPod Touch — since it launched on Dec. 4. It’s been in the top 40 most popular kids’ apps since then. That sounds like a lukewarm reception at best.University of Michigan developmental behavioural pediatrician Jenny Radesky, who co-signed the letter, said she’s never met a parent who was clamouring to get their children onto social media at an earlier age.“One can only assume that Facebook introduced it to engage users younger and younger,” Radesky said.That’s troubling, she said, because younger children haven’t yet developed the cognitive skills that enable them to think about and regulate their thoughts and actions and “allow them to realize when persuasive technology design might be manipulating them.”At the time it launched Messenger Kids, Facebook said it won’t show ads or collect data for marketing to kids. And it stressed that it won’t automatically move users to the regular Messenger or Facebook when they get old enough — though it might give them the option to move contacts to Messenger down the line.___Ortutay reported from New York.last_img read more

Five things to watch for in the Canadian business world in the

first_imgTORONTO – Five things to watch for in the Canadian business world in the coming week:More beats for banks? Bank of Montreal, Scotiabank, TD Bank and National Bank are set to report their third-quarter results this week. The results from the four banks follow Royal Bank and CIBC, which both reported profits that beat expectations and raised their dividends last week.Duties deadlineThe U.S. International Trade Commission votes on final phase anti-dumping and countervailing duty investigations into newsprint from Canada on Monday. The U.S. government gave most Canadian newsprint producers a reprieve earlier this month by lowering final anti-dumping and countervailing duties after several U.S. businesses and politicians complained the tax on Canadian newsprint threatens the already-struggling newspaper industry.Economic updateStatistics Canada releases its latest reading on the country’s economy on Thursday, with a report on economic growth for the second quarter. The economy slowed in the first quarter to its lowest rate in two years, largely attributed to a pullback in the real estate market. The latest assessment comes ahead of the Bank of Canada’s next interest rate announcement set for Sept. 5.The next Trans Mountain battleThe Federal Court of Appeal will release its decision in the case of Tsleil-Waututh Nation et al. v. Attorney General of Canada et al. over the Trans Mountain pipeline on Thursday. Opponents of the pipeline project were dealt a major blow on Thursday when the Supreme Court of Canada dismissed an application from the City of Burnaby to consider overturning a lower court decision that denied the port city leave to appeal a ruling by the National Energy Board.NAFTA talksCanada is waiting to rejoin the North American Free Trade Agreement negotiations as the United States and Mexico work to resolve their bilateral issues amid reports suggesting the announcement of a deal is close. Foreign Affairs Minister Chrystia Freeland said last week that she’s been “very encouraged” by signals from Washington.last_img read more

Environment minister touts balance at Alberta Climate Summit

first_imgCALGARY (660 NEWS) – Alberta Environment and Parks Minister Shannon Phillips was a featured speaker at the Alberta Climate Summit in Calgary Wednesday afternoon.She told the crowd at the BMO Centre that especially young people are passionate about climate change, and that’s why they will be launching the Alberta Youth Climate Change Council.But along with promoting the province’s Climate Leadership Plan, Phillips says decisions about the environment and energy development need to be based on science, evidence and facts.The minister also took aim at the conservative elements in the province, and criticized those who say climate change is not real.Following her speech, she also met with reporters to discuss this balance and how to move ahead with projects such as the Trans Mountain Pipeline Expansion.When asked about how the province can keep the environment safe but also develop oil and gas projects, Phillips believes the NDP has proven it can be done — shown by two years of economic growth and the introduction of the new Climate Leadership Plan.“This is a reality that not only puts food on the table for thousands of Alberta families but also millions of Canadians. So what we need to do as an energy economy is ensure we are poised to be able to compete in a carbon-constrained world because we know that climate change is real,” said Phillips.Then, looking at how they can transition into that carbon-constrained future, Phillips added that policies like the carbon tax help out.“We need to make sure that we are thoughtfully reinvesting the proceeds of our price on pollution into making those innovative solutions a reality, lowering costs for producers, as well as creating new jobs.”At the Alberta Climate Summit, where Environment Minister Shannon Phillips is speaking. Summit is hosted by the Pembina Institute. Phillips talking about science based methods to combat climate change, criticizes doubters in the Conservative party #ableg #climate pic.twitter.com/hnTywkU9hG— Tom Ross (@Tommy_Slick) September 26, 2018Phillips was also asked about her upcoming meeting in Ottawa, along with Energy Minister Marg McCuaig-Boyd, to lobby for changes over Bill C-69.She said that the first issue over the bill which helps determine how energy projects are approved in Canada concerns the time-frames.“We still don’t have much in the way of comfort around timelines, so that’s one of the biggest things. Two, better defining the scope — in particular for the pre-assessment. I still think there are still some issues there. And three, it’s just a little bit too vague in terms of some of the federal encroachment into provincial jurisdiction on work that we are already doing.”Also on Wednesday, a new three-member panel was named to the National Energy Board to conduct another review on the Trans Mountain expansion.Phillips says the NDP government will be monitoring their upcoming discussions.“If Alberta begins to see that games are being played with respect to this process, then we will be going back to the federal government to explore a legislative solution. Right now, we do have to take a bit of a wait and see approach, but if we can adhere to that 22-week timeline we believe that this project will move forward in the time-frame that it ought to, and shovels can go back into the ground and people can get back to work as they were in late August.”last_img read more
