Extensive dynamic thinning on the margins of the Greenland and Antarctic ice sheets

first_imgMany glaciers along the margins of the Greenland and Antarctic ice sheets are accelerating and, for this reason, contribute increasingly to global sea-level rise(1-7). Globally, ice losses contribute similar to 1.8 mm yr(-1) (ref. 8), but this could increase if the retreat of ice shelves and tidewater glaciers further enhances the loss of grounded ice(9) or initiates the large-scale collapse of vulnerable parts of the ice sheets(10). Ice loss as a result of accelerated flow, known as dynamic thinning, is so poorly understood that its potential contribution to sea level over the twenty-first century remains unpredictable(11). Thinning on the ice-sheet scale has been monitored by using repeat satellite altimetry observations to track small changes in surface elevation, but previous sensors could not resolve most fast-flowing coastal glaciers(12). Here we report the use of high-resolution ICESat (Ice, Cloud and land Elevation Satellite) laser altimetry to map change along the entire grounded margins of the Greenland and Antarctic ice sheets. To isolate the dynamic signal, we compare rates of elevation change from both fast-flowing and slow-flowing ice with those expected from surface mass-balance fluctuations. We find that dynamic thinning of glaciers now reaches all latitudes in Greenland, has intensified on key Antarctic grounding lines, has endured for decades after ice-shelf collapse, penetrates far into the interior of each ice sheet and is spreading as ice shelves thin by ocean-driven melt. In Greenland, glaciers flowing faster than 100 m yr(-1) thinned at an average rate of 0.84 m yr(-1), and in the Amundsen Sea embayment of Antarctica, thinning exceeded 9.0 m yr(-1) for some glaciers. Our results show that the most profound changes in the ice sheets currently result from glacier dynamics at ocean margins.last_img read more

12-Year-Old Son Of Metallica’s Robert Trujillo Debuts With Korn For South American Tour [Videos]

first_imgKorn hit Bogotá, Colombia, last night, kicking off their South American tour with Tye Trujillo, the twelve-year-old son of Metallica’s Robert Trujillo. The little bass prodigy was tagged in to replace Korn’s long-standing bassist Reginald “Fieldy” Arvizu for the South American leg of the tour due to “unforeseen circumstances,” though Arvizu will rejoin the group for the North American leg of the Serenity of Suffering tour. Fans in Colombia did not seem to mind the debut of Arvizu’s replacement, however; Trujillo proved himself as a skilled musician despite his young age. You can watch videos of the younger Trujillo shredding with Korn below, all courtesy of Juan Sebastián Rodríguez Isáziga.last_img

Program enables students to confront societal issues in international settings

first_imgThe goal of the International Summer Service Learning Program (ISSLP) is for students to become aware of complex social issues that will help them discern their responsibility as global citizens in our world, director of international engagement at the Center for Social Concerns Rachel Tomas Morgan said.ISSLP is a community-based learning abroad program Tomas Morgan designed, implemented and directs, according to the Center for Social Concerns website. The program has averaged 300 applications annually and has 64 positions available to freshman, sophomores and juniors, Tomas Morgan said.“Students encounter day-to-day realities facing local communities in international settings,” she said in an email. “We have some amazing sites of deep learning and cultural immersion. I encourage students to come to an ISSLP Information Session and to come by Geddes Hall to review binders full of information from past participants so as to discern which sites are the best fit for their own particular interests, skills and experiences.” Photo courtesy of Lindsey Whalen Students participating in an ISSLP in Buenos Aires, Argentina engage with the local community in a schoolyard game. Online applications close on Oct. 29, and site committees review these applications throughout the month of November. Students are then invited to interviews for positions, and confirmations of participation are due by Dec. 27.“While it is a competitive process, we encourage all students — frosh, sophomores and juniors — who can see themselves living and working in community with communities to apply,” Morgan said.Senior Molly Knapp spent 10 weeks in Trujillo, Honduras for her ISSLP during the summer after her sophomore year. Knapp worked at a Catholic children’s home as a special education, English and math teacher for elementary and middle school kids.“Some of my favorite memories would definitely be in the classroom,” Knapp said. “It was always awesome when I was teaching a difficult math concept and to finally see the light go on in one of the kid’s eyes who had been struggling for a while.”Prior to her ISSLP experience, Knapp had also completed a Summer Service Learning Program (SSLP) — another Center for Social Concerns program — in Minneapolis at a community center for the Latino population working specifically with senior citizens. Additionally, Knapp said she has always had a desire to work with kids, being the oldest of four kids herself.“I applied to do an ISSLP partly because of my experience with the SSLP,” she said. “I just found so much joy in working with both kids and senior citizens, and really wanted to expand my horizons by learning more about the world and how to become a global citizen by connecting with other populations.”Although she is still trying to discern what her future path will be, Knapp said she will hopefully be involved with international human rights law, which relates directly to her ISSLP.“I worked with a lot of kids whose parents had been members of the international drug trade, and that is an issue that I have been studying in my classes, and is something that I’m very interested in continuing to learn about and hopefully tackle in a career in policy and legislation in the future,” Knapp said.Knapp said she went down to Honduras with one other Notre Dame student, but at the site there were two long-term volunteers who were Notre Dame graduates. Having that connection and being able to talk about their Notre Dame experiences helped make the transition to living abroad easier, she said.As for who should apply, Knapp said although each site has a different level of spirituality attached to it and that the sites are not identical in terms of experiences, the students who apply should all share a particular attribute. “I would say that this program would be good for anyone who is willing to step outside of their comfort zone and to really form relationships with a wide variety of people in different circumstances,” Knapp said.

Let my information go: The glory and peril of data democratization

first_img 1SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr Credit unions are often plagued by their data being locked up in the core processor and other standalone systems. Increasingly, they are adopting data warehouse solutions to free and integrate this data so cutting edge analytical tools can be employed to solve tough business problems.However, a new problem then becomes apparent. Once business users realize long-imprisoned data is now liberated, they clamor for information. This puts pressure on the IT department to meet the growing demand for reporting and analytics.Beleaguered IT executives seeking relief often look to the holy grail of self-service analytics. In this approach, data access and analytical tools are put in the hands of business users so they can do their own reporting and analysis. This seems like an attractive solution to both IT and information consumers. In fact, self-service analytics often is hailed as the height of “data democratization” or further freeing data by releasing it into the hands of the masses.While this sounds very virtuous, poorly deployed self-service analytics can cause as many problems as it solves.Data warehouses can serve as the place for all organizational data to be centralized. The goal is to provide a single data source for all analytics purposes. However, most enterprise data warehouses are very complex, interrelated arrangements of files. If semi-trained business users try to query these files without sufficient knowledge, very different results can appear. This is frustrating to the business users and cast doubt on the accuracy of the data warehouse. continue reading »last_img read more

PMT board: Decision to fix contributions hurt funding levels

first_imgSpeaking to IPE’s Dutch sister publication Pensioen Pro, Benne van Popta, PMT’s employer chairman, acknowledged that it would have been better to have taken stock midway through the five-year period.He highlighted that PMT’s liabilities had significantly increased since 2014 due to falling interest rates as a consequence of the ECB’s quantitative easing programme. Liabilities had also been affected by the reduction of the Dutch discount rate, as well as macro-economic conditions.“In hindsight, we can establish that making arrangements for a five-year period is too complicated in a fast changing world,” Van Popta said. Dutch metalworkers’ pension scheme PMT could have reduced the impact of looming pension cuts if its associated employers and unions had not opted for a five-year fixed contribution level, according to the scheme’s supervisory board.The board of the €77bn industry-wide scheme PMT – one of the largest in the Netherlands – said the 2014 decision to fix contributions had led to payments into the scheme being too low. Contributions sustained a funding level of approximately 80%, the board said.PMT’s current funding level is 101.7%. This has to improve to at least 104.3% by the end of this year to avoid a reduction of pension rights and benefits in 2020.According to a spokeswoman for PMT, the cumulative contribution shortfall had effectively reduced the scheme’s funding level by 2.3 percentage points. Metal industry scheme PMT must hit 104.3% funding by the end of 2019In its annual report, PMT’s board said that, if coverage ratio exceeded 100%, rights cuts would be “against all sense of justice”.It attributed the looming cuts to “crushing regulation, which piled prudence onto prudence, combined with requirements for high financial buffers and risk-free interest rates”.“This raises the incorrect impression that pension funds would barely be able to achieve returns on investments for the coming decades,” it argued.The scheme’s board, nevertheless, said it appreciated that it had not attempted to reassess contribution arrangements “as they had led to stability in the sector”. In its opinion, the board had balanced the various interests at stake.PMT’s chairman said contributions would have to rise from 22.2% to 29% in order to be sufficient. He suggested that the pain could be eased by reducing annual pensions accrual.Investment returnsLast year, the metal scheme’s investment portfolio returned 0.2%, underperforming its long-term target by 3.9%.Its 51% matching portfolio of fixed income holdings gained 3% on the back of falling interest rates, but PMT’s return portfolio lost 2.7%.Equity allocations delivered an overall loss of 3.8%, with a 15% gain on private equity – which was in stark contrast to a 13.5% loss from emerging markets equity.The pension fund added that it had incurred a 4.6% loss on high-yield bonds, but real estate had generated 2.4%.The metalworkers’ scheme reported administration costs per participant of €75. Asset management and transaction costs were 43bps and 7bps, respectively, it said.PMT attributed 58% of asset management costs to management fees for its €3.9bn private equity allocation.The pension fund has more than 1.4m participants, 408,000 of whom are employed by affiliated companies and 155,000 of whom are pensioners.last_img read more
