Reductions in CFC-11 emissions put ozone recovery back on track

first_imgReductions in CFC-11 emissions put ozone recovery back on track Massachusetts Institute of TechnologyA potent ozone-depleting chemical whose emissions unexpectedly spiked in recent years has quickly dropped back to much lower levels, putting the recovery of the stratospheric ozone layer back on track, according to a new study by scientists at MIT, the University of Bristol, and other institutions in South Korea, the U.S., Japan, Australia, and Switzerland.The chemical in question is CFC-11, a chlorofluorocarbon that was once commonly used for refrigeration, insulation, and other purposes. When emitted to the atmosphere, CFC-11 can loft into the stratosphere, where the sun’s ultraviolet radiation breaks the chemical down to release chlorine – a noxious chemical that then eats away at ozone, stripping away the Earth’s natural shield against UV rays.CFC-11 and other chlorofluorocarbons are now banned under the Montreal Protocol, an international treaty under which every country agreed to phase out the chemicals’ production and use by 2010. But in 2018, a team of scientists reported a concerning spike in global emissions of the chemical beginning in 2013. In 2019, a second team reported that a significant portion of the emissions could be traced to eastern China, predominately the Shandong and Hebie provinces.Now, in two papers published today in Nature, the same teams report that global annual emissions of CFC-11 into the atmosphere have declined sharply, by about 20,000 U.S. tons, from 2018 to 2019. The researchers traced a substantial fraction of the global emission reductions to the very same regions of eastern China where they had previously reported the original spike. The results are consistent with evidence that the country has taken successful actions to stamp out illegal production of this ozone-depleting chemical.“This is tremendously encouraging,” says Ronald Prinn, the director of the Center for Global Change Science at MIT and a co-author on both papers. “If emissions of CFC-11 had continued to rise or even just leveled off, there would have been a much bigger problem building up. The global monitoring networks really caught this spike in time, and subsequent actions have lowered emissions before they became a real threat to recovery of the ozone layer.”A brief history of the spikeBoth the original spike and subsequent drop in CFC-11 emissions were detected by the researchers using two independent networks.One is a global monitoring network operated by the National Oceanographic and Atmospheric Administration (NOAA), comprising about 30 stations. Researchers at each site collect air samples and send them to a central laboratory, where the air is analyzed for CFC-11 and many other trace gases. The weekly measurements, from sites around the world, give an accurate average picture of the chemical species circulating in the global atmosphere.The other network is the Advanced Global Atmospheric Gases Experiment, or AGAGE, an MIT-led effort funded in part by NASA, with more than a dozen monitoring stations situated on coastal and mountain sites around the world. The AGAGE stations take automated on-site measurements of passing air parcels about every hour, monitoring for more than 50 trace gases, including CFC-11, to provide detailed records of the regional and global atmosphere.In a 2018 Nature report, the researchers analyzed measurements from NOAA and observed that, from 2014 to 2016, global emissions of CFC-11 grew by more than 14,000 U.S. tons a year – a 25 percent increase from emissions between 2002 and 2012. In a subsequent 2019 Nature report, regional measurements taken by AGAGE stations in Hateruma, Japan, and Gosan, South Korea, along with three-dimensional modeling, showed that about half or more of these emissions came from eastern China, primarily from the factory-heavy Shandong and Hebei provinces.Following these 2018 and 2019 reports, the scientists continued to track the chemical through the atmosphere, at both global and regional levels.In the first of the two new Nature papers, they analyze both NOAA and AGAGE global data and report a dramatic turnaround: From 2018 to 2019, CFC-11 annual emissions dropped throughout the global atmosphere by about U.S. 20,000 tons, returning to levels prior to 2012, following the chemical’s 2010 global phaseout.In the second paper, based on AGAGE measurements, the scientists observed that CFC-11 emissions specifically from eastern China hit a peak around 2017. At some point soon afterward, levels began to drop, although the researchers cannot say exactly when the regional turnaround occurred, as the South Korean station sustained typhoon-related damage that resulted in some data gaps. Despite these gaps, the group observed a decline in CFC-11 annual emissions, by about 11,000 U.S. tons from eastern China, through 2019.As the researchers write in the paper, “it seems that any substantial delay in ozone-layer recovery has been avoided, perhaps owing to timely reporting, and subsequent action by industry and government in China.”“Continuous vigilance”However, there is still work to be done. While it appears that CFC-11 emissions from eastern China have declined, indicating that significant illegal production of the chemical there has ceased, these emissions only account for roughly half of the global emissions. Where the remainder could have come from is still unknown.In general, CFC-11 is currently emitted in large amounts through leakages during new production and during subsequent use in refrigeration and manufacture of foams. The chemicals can also leak out from “banks” of old, discarded refrigerators and foams, though at a much slower and more diffuse rate than the rapid regional increase observed in 2013.“The challenge now is to ask, where’s the rest of it coming from?” says Prinn, the TEPCO Professor of Atmospheric Science in MIT’s Department of Earth, Atmospheric and Planetary Sciences. “We will need to expand measurements and modeling to identify new sources, and continue to keep watch. Hopefully, emission levels will continue to drop.”Going forward, the scientists hope to add more stations to the AGAGE network, so that they might identify and quantify other regional sources of CFC-11, particularly in rapidly industrializing parts of the world.“Clearly this story shows that, in order to ensure that countries are adhering to international agreements like the Montreal Protocol, continuous vigilance is required,” Prinn says. “You can’t stop measuring these chemical species and assume the problem is solved.”This research was supported, in part, by NASA and NOAA. /University Release.

What Do Your Customers Want From You?

Slater has taught more wineries and winery associations how to create and improve the effectiveness of their direct marketing programs and to make the most of each customer’s potential than anyone in the wine industry today.Follow E on twitter @esavant and facebook. Advertisement AdvertisementKnowing what your customers want is part and parcel of making your customers happy and ensuring that they will continue to buy from you. Here are some tips on how to engage your customersUse Their NamesNot only will customers remember you if you remember their names and use their names (a couple of times in the conversation) they are also more aware and interested when they hear their names. Try not to overuse the name. Sometimes when I have been on a phone call with a company and the employee has been told to use the customer’s name, they use it every second word, which is way too much and a little irritating.PersonalizeA key way to make customers happy is to make each experience personal. A personalized experience not only makes customers happy, they are also willing to pay more for a personalized experience. Treat each set of customers as individuals with an individual experience.Tell StoriesWhen we tell a story, customers can become a part of that story. Powerful messages about the company are left in their minds through the story. Keep your stories fairly short, so customers don’t lose interest.Involve Your CustomersAsk customers for their ideas or present ideas you have and ask for their input. If you implement a customer’s idea, make sure they are rewarded for their input.Surprise CustomersAn unexpected treat or gift (no matter how small) will please your customers and will get them talking to their friends about how great the company is.Time & Memories Many customers value time well spent and the memories that are created much more than they do discounts. Though in most businesses there is more talk about pricing than there is about what the product will mean to the customer. Start focusing more on the memories that they can make with your products.A tip of the glass from me to you.

Attorney Attacks Dr. Blythe’s Credibility

first_imgRelatedAttorney Attacks Dr. Blythe’s Credibility By BALFORD HENRY, JIS Reporter & Editor Advertisements FacebookTwitterWhatsAppEmail KINGSTON — Attorney for the Jamaican Redevelopment Foundation (JRF), Sandra Minott-Phillips raised a number of issues regarding former Minister of Water and Housing. Dr. Karl Blythe’s credibility as a debtor, as the FINSAC Commission of Enquiry resuming hearings Thursday morning (August 4) at the Jamaica Pegasus Hotel, New Kingston. Attorney for Dr. Blythe, Leonard Green, criticized Mrs. Minott-Phillips for insisting on focusing on Dr. Blythe’s record of personal debt, despite his acknowledgement that he owed the debts. Chairman of the Commission, Worrick Bogle, agreed with Mr. Green that since Dr. Blythe did not deny owing the debts, there was no need to continue “flogging a dead horse”. However, Mrs. Minott-Phillips insisted on cross examining the former Minister on his debt record, especially a debt owed to the Workers Bank which ballooned from $900,000 to $5 million in no time “He himself ran up significant debt, for which he has not made any payments, or certainly not made sufficient payment to discharge it,” she said. “He has not only imperiled the properties he provided as security, but also the properties of others who provided security for these debts,” she went on. “I think since what is here being sought from Dr. Blythe is his view of whether debtors were treated fairly or unfairly, then it is certainly relevant to the Commission of Enquiry to establish whether Dr. Blythe conducted himself and his business fairly or unfairly, or whether he behaved in a manner that was deserving of some treatment that he expected in relation to favourability, whereby he could just borrow money and expect that, because of his station, he would not have to repay,” she commented. When Commissioner Bogle again pointed to Dr. Blythe’s acknowledgement of the debts, Mrs. Minott-Phillips suggested that the issue was not whether he owed money, but whether he was a credible witness. “The point is not whether or not he owes the money. That is not in dispute. The point is, is he a witness that the Commission can rely on to establish whether FINSAC or the JRF treated debtors fairly or unfairly, and I am saying his character and his conduct are squarely an issue,” she stated.

Kuehne to receive Criminal Law Section’s Selig I. Goldin Award

first_img May 19, 2021 By Jim Ash Senior Editor Top Stories Kuehne to receive Criminal Law Section’s Selig I. Goldin Award Ben KuehneMiami attorney Ben Kuehne, dubbed the “Iron Lawyer” for his courtroom and Iron Man triathlon prowess, is the latest recipient of the Criminal Law Section’s highest honor, the Selig I. Goldin Award.The award is bitter-sweet for Kuehne, who prefers the title “lawyer” with Kuehne Davis Law, P.A. Kuehne said he is especially grateful because he reveres Bar service, and some of the lawyers he considers mentors were past Selig Goldin Award recipients.“I’m really very honored, it is something I never expected,” he said.Kuehne was to have received the award last summer, but the ceremony was postponed when the COVID-19 pandemic forced the Bar’s Annual Meeting to convene virtually. Sadly, former Florida Supreme Court Justice Gerald Kogan, one of Kuehne’s earliest and most influential mentors, was scheduled to introduce Kuehne, but the former justice died March 4 at the age of 87.“Without his mentorship, his guidance, I would not be anywhere close to the lawyer I am,” Kuehne said.However, Kuehne said he is honored that his former law partner, a Criminal Law Section executive council member Neal Sonnett, has agreed to do the honors. Kuehne is scheduled to receive the award at Criminal Law Section executive council meeting on June 11.Criminal Law Section Chair Warren Lindsey calls Kuehne a “champion for justice and respect for the court system.”“Ben Kuehne personifies all of the attributes of an outstanding criminal trial lawyer,” Lindsey said. “While he is always a fierce and effective advocate for his clients, he can disagree without being disagreeable, and always exhibits professionalism and ethics in his interactions with others.”A fixture in South Florida legal circles with a penchant for brightly colored bow ties, Kuehne is one of the state’s most prominent white-collar criminal defense attorneys. Also an election law specialist, Kuehne stepped into the national spotlight in 2000 when he represented former Vice President Al Gore, and the Gore/Lieberman Recount Committees, during the presidential recount.Triple board certified in Appellate Practice, Criminal Appellate Law, and Criminal Trial Law, the 1977 University of Miami law school graduate has served, among many other posts, as a Florida Bar board member and chair of the Criminal Law Section, Appellate Practice Section, and Council of Sections. He is a past president of the Dade County Bar Association and is a founding member of the Florida Association of Criminal Defense Lawyers.Friends and colleagues say Kuehne is a natural choice for the Selig I. Goldin Award. Former Florida Bar President Hank Coxe considers the recognition “long overdue.”“We all have our short list of lawyers, in times of crisis, to whom we turn for wisdom when we need it, but can’t find it,” Coxe said. “Ben Kuehne has always been there — leadership, trust, mentoring, and commitment to the values of this profession. He differs from Quixote in that he has beaten the windmills, and it has made our profession better.”Sonnett says his former partner “richly deserves” the honor.“Ben Kuehne embodies the outstanding characteristics of Selig Goldin — trial excellence, strict adherence to ethics, devotion to the rule of law, and service to the legal profession and The Florida Bar,” Sonnett said. “Ben has devoted much of his career to protecting the rule of law and improving the criminal justice system, and his contributions have been extraordinary.”The award takes its name from former Gainesville attorney and Criminal Law Section executive council member Selig I. Goldin.Before he died of cancer in 1980, the 41-year-old lawyer was known for refusing to turn away clients whose cases were too controversial or who couldn’t pay and was a model of “competence, service and compassion,” according to a Criminal Law Section biography.Hollywood attorney Harvey Sepler, who chairs the Criminal Law Section’s Selig Goldin Committee, said Kuehne exhibits Goldin’s finest qualities. A friend for more than 30 years, Sepler said Kuehne mentored him and many other lawyers, and is the “epitome of professionalism.”“A former chair of the Criminal Law Section, longtime member of The Florida Bar Board of Governors, and advocate for fairness in the criminal justice arena,” Sepler said. “I can’t think of anyone who deserves the Selig Goldin award more than him.”last_img read more

We’ve grown the beta testing over time. We’ve gone out with invitations to about five million of the Verizon Wireless customers and we will be adding them onto the platform this month and we expect to go live with it at the end of September,” he said.Later during his conversation with Goldman analyst Brett Feldman, the Verizon chief switched to the subject of profitability. “So I see a plateauing, if you will, between 2015 and 2016 and then I see 2017 we move back into the growth trajectory.”Profitability was impacted by a number of factors, including the changing way subscribers pay for handsets, a shift in wireline financial comparisons following the expected first-half 2016 sale of operations to Frontier Communications, and its push into new areas such as mobile video and IoT.He then referred to a decision made by former Verizon CEO Ivan Seidenberg some years ago: “So it’s a little bit — in chatting with the team — it’s a little bit of our FiOS moment, if you think about it. When Ivan said you know we’ve got to shift the framework of this business off of copper and onto fiber, we are shifting the framework of this business more onto digital media than our traditional services, so that’s why the frameworks change and the comparables are going to be a little difficult for us in 2016.”McAdam also talked up IoT’s contribution. In the first half of the year, Verizon had seen around $320 million of revenue from that area, which for Verizon is  “not a big deal”.“But we are generating by far the largest amount of revenue from Internet of Things of any company in the US,” he claimed.  And future projections from the likes of Cisco show how IoT will be making a bigger contribution over time. “So I think it will be a meaningful line item on the budgets and our results for investors to look at in 2017,” he said.last_img read more
