SHEDDING LIGHT

How the project benefited the library

Then: Lights in the Special Collections area were typically on 10-13 hours per day

Now: Lights now are only activated when there is activity and only in the area where that activity is occurring

Then: A compact fluorescent bulb is 54 watts, lasts about 10,000 hours and produces heat

Now: An LED bulb is 25 watts, lasts about 50,000 hours and doesn’t produce heat.

Paper and photographs can’t take the heat. Or the light.

Both elements cause historic, fragile documents to breakdown over time, much to the dismay of curators of the Special Collections at the Marriott Library.

Enter a trio of students — Sierra Govett, Dillon Seglem and Yinhuan Huang — in search of a project for Jennifer J. Follstad Shah’s environmental and sustainability studies capstone class last spring.

Govett initially proposed they tackle excessive light use across campus, especially at times when buildings are unoccupied.

“A lot of buildings on campus have lights on more than they should and we wanted to find some place we could address lighting at a large enough scale to make a difference, said Govett.

But the students abandoned that idea after realizing vast differences in lighting systems from floor-to-floor and building-to-building would make a standardized solution impossible.

Bill Leach, sustainability project coordinator for Facilities Management, suggested the students instead look at what might be done to address lighting concerns in the Marriott Library. Ian Godfrey, director of library facilities, was “not only excited about the prospect of a lighting controls project, but had an area in mind,” Leach said.

That area? Special Collections.

Leach, Godfrey and Emerson Andrews, Sustainable Campus Initiative Fund (SCIF) coordinator, helped the students conduct an audit of the space, come up with a plan and develop a budget.

Their idea: install a new lighting system with LED bulbs that are motion and daylight sensitive. Lights above each row activate only when someone moves into the area and there is insufficient daylight.

“To take light off these resources is a huge benefit for us,” Godfrey said. “Everything in here is rare and unique. Paper is always in a state of degradation. Anytime you are lowering the temperature and reducing the heat, you are slowing the deterioration process.”

The students applied for and received a SCIF revolving loan of $40,000, which paid for installation of a new lighting system over the summer. The loan fund is specifically used for energy and money saving ideas proposed by students, faculty and staff for energy conservation, renewable energy production and water conservation projects. A Rocky Mountain Power wattsmart incentive grant helped off-set some of the project’s cost.

The library will repay the loan over 13 years, using money from utility cost savings. But the impact — both monetary and in preservation of its collections — will be ongoing.

“I am thrilled that this project, initiated by these three students in my capstone class, is coming to fruition and will help to reduce the campus carbon footprint while preserving library resources,” said Follstad Shah, an assistant professor in environmental and sustainability studies and research assistant professor in geography.

The SCIF revolving loan fund used in the project is available to all students, faculty and staff who have an idea for saving energy and money. It has paid for other energy projects, such as solar panels and heating system upgrades, but this is the first lighting project, said Myron Willson, deputy chief sustainability officer.

“We were pretty excited to do something that made such a difference,” said Govett, who graduated last spring with degrees in environmental studies and ballet.

Govett and Seglem toured the retrofitted space for the first time in mid-November.

“It’s really cool to come in here and see it working with the motion sensors and all,” said Seglem, a senior majoring in environmental studies.

SAVING BIRDS

Funded by SCIF

The Sustainable Campus Initiative Fund, created through an ASUU initiative in 2008, collects about $180,000 yearly from a $2.50 per student fee. Since 2009, it has awarded more than $900,000 to projects aimed at enhancing sustainability on the U campus.

The fund receives about 30 to 45 proposals each year and approves grants for 20 to 25 requests, which typically range from $200 to $40,000, according to Emerson Andrews, SCIF coordinator.

Projects funded have included the edible campus gardens, a beekeeping initiative, installation of screech owl habitat boxes, Bike to the U Day, several solar energy initiatives, and the Wild & Scenic Film Festival. Learn more by clicking here.

Last November Professor Barbara Brown and some colleagues were in the middle of interviewing a candidate for a position in the Department of Family & Consumer Studies when there was a smack on the window — a noise so loud and violent it startled and instantly silenced the candidate.

A bird in full flight had flown into the second-story window on the northeast side of the Alfred Emory Building.

Forty minutes later, interview over, Brown ventured outside and there on the ground was the still-stunned bird — a Cedar Waxwing.

Years earlier she had found a dead Bohemian Waxwing near the building, but thought it was an isolated incident. But now, as Brown surveyed the area, she found seven more carcasses under the mirrored glass entryway that perfectly reflects the sky and trees on Presidents Circle.

“It was discouraging to realize I may have been working here for years and not known I needed to take action to prevent these bird strikes,” said Brown, an environmental psychologist who studies links between physical environments and human behavior. She considers herself a “sort of birder” but Cedar Waxwings “have always been one of my favorite birds. They are the finest, cutest birds you’ve ever seen.”

Between November 2017 and March 2018, Brown counted a total of 20 dead birds near her building; most were Cedar Waxwings.

“The birds think they are flying right into an open area, smack the mirrored glass and die,” said Brown, who deduced that the birds are attracted to the fruiting crabapples on the lawn at Presidents Circle.

Brown enlisted three students to work on the project: Angelo Antonopoulos, a senior from Greece majoring in environmental and sustainability studies; Sarah Siddoway, a senior from Farmington majoring in biology; and Erika Kusakabe, a senior from West Jordan also majoring in environmental and sustainability studies.

The team also connected with Sarah Bush, an associate professor of biology who is collecting the bird carcasses to use in a parasite research project, and Lisa Thompson, exhibit developer and interpretive planner at the Natural History Museum of Utah (NHMU). Some birds, if in good structural condition, may also be prepared to use as museum specimens.

The team researched Cedar Waxwings; bird deaths; bird strikes and contributing building design factors; bird migration patterns; and mitigation measures.

They concluded that the 20 dead birds at AEB appeared significant. In comparison, the 2017 Salt Lake Avian Collision Survey of downtown Salt Lake City found only 44 dead birds in a 20-block area. In addition, the birds found downtown represented a variety of species.

They also determined that unique features of the northeast end of AEB — tunnel-like openings to multiple reflective windows that make it appear to be a passageway — were contributing to the problem.

The only way to deal with this “hotspot of death” was to mitigate the danger by somehow altering the windows, the team concluded.

The best solution was something called “Feather Friendly Bird Deterrent” — a film that is placed on windows and then removed, leaving behind little dots even spaced over the surface. Birds see the dots and recognize an obstacle, while people are still able to see through the window.

“The problem is that the site is three stories tall and to get to the upper windows you need a lift or scaffolding, which is expensive,” she said. The team learned the cost of doing all the north-end windows would be about $27,000.

Doing something, they decided, was better than nothing, so in September they applied for a $10,000 SCIF grant from the U’s Sustainable Campus Initiative Fund (SCIF) — enough money to cover a third of the windows.

“Our goals are to mitigate an existing hotspot of bird deaths from window strikes, to evaluate the effectiveness of the mitigation, and to develop a citizen science outreach component to raise awareness and identify whether other hotspots exist,” the team wrote in its grant proposal. “In this way, we are consistent with the SCIF mission statement that funds projects that ‘reduce the University of Utah’s negative impact on the environment.’”

The AEB Bird Strike Mitigation proposal received approval in October. Last week, Blake Parrish of Scottish Window Tinting installed the protective coating on a section of reflective windows.

The fact that funding allowed only a portion of the windows to be covered has created a controlled research design to test the effectiveness of the film. If additional dead birds are found, the team will be able to determine which section they struck.

The team’s grant proposal also included an educational outreach component aimed at raising awareness of the diversity of birds on campus and cataloguing other hot spots in need of mitigation.

“We hope that students start to appreciate the connections between bird life and campus life and realize it’s not like birds are ‘over there somewhere’ but that birds are all around us,” Brown said.

Siddoway worked with the NHMU’s Thompson to develop the “University of Utah Bird Window Collision Project,” a site on iNaturalist that encourages citizen engagement in science. People can upload photos of dead birds and information about the site and circumstances where the bird was found. Posters around campus advertise and encourage participation in the project.

“I am really interested in conservation,” Siddoway said. “I graduate in December and want to pursue a career in conservation and research, so this seemed up my alley. We had ups and downs and there were points we didn’t know if we would get any bird mitigation windows, but I am glad we got at least part of them.

“It is amazing, actually, that things are happening,” she said.

Bird friendly buildings

Several other buildings at the U — the S.J. Quinney College of Law and Gardner Commons — have bird-friendly windows; the features are primarily intended to reduce heat, but that also deter bird strikes. Feather Friendly films such as that used in this project are a good option for older buildings.

WHAT YOU CAN’T SEE CAN HURT YOU

What if you could see nasty microscopic air pollutants in your home?

University of Utah School of Computing assistant professor Jason Wiese (left) and computing doctoral student Jimmy Moore conducted a study to determine if homeowners change the way they live if they could visualize the air quality in their house. They provided participants with air pollution sensors, a Google Home speaker and a tablet to measure and chart the air quality in their homes.

Engineers from the University of Utah’s School of Computing conducted a study to determine if homeowners change the way they live if they could visualize the air quality in their house. It turns out, their behavior changes a lot.

Their study was published this month in the Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies. The paper was also presented Oct. 9 in Singapore during the “ACM International Joint Conference on Pervasive and Ubiquitous Computing.” The paper can be viewed and downloaded here.

“The idea behind this study was to help people understand something about this invisible air quality in their home,” says University of Utah School of Computing assistant professor Jason Wiese, who was a lead author of the paper along with U School of Computing doctoral student Jimmy Moore and School of Computing associate professor Miriah Meyer.

During the day, the air pollution inside your home can be worse than outside due to activities such as vacuuming, cooking, dusting or running the clothes dryer. The results can cause health problems, especially for the young and elderly with asthma.

University of Utah engineers from both the School of Computing and the Department of Electrical and Computer Engineering built a series of portable air quality monitors with Wi-Fi and connected them to a university server. Three sensors were placed in each of six homes in Salt Lake and Utah counties from four to 11 months in 2017 and 2018. Two were placed in different, high-traffic areas of the house such as the kitchen or a bedroom and one outside on or near the porch. Each minute, each sensor automatically measured the air for PM 2.5 (a measurement of tiny particles or droplets in the air that are 2.5 microns or less in width) and sent the data to the server. The data could then be viewed by the homeowner on an Amazon tablet that displayed the air pollution measurements in each room as a line graph over a 24-hour period. Participants in the study could see up to 30 days of air pollution data. To help identify when there might be spikes in the air pollution, homeowners were given a voice-activated Google Home speaker so they could tell the server to label a particular moment in time when the air quality was being measured, such as when a person was cooking or vacuuming. Participants also were sent an SMS text message warning them whenever the indoor air quality changed rapidly.

Participants were given an Amazon table that displayed the air pollution data in an easy-to-understand line chart so they could see when and why the air quality worsened. Homeowners also could label points in time when the pollution would spike, such as when they were cooking or vacuuming.

During the study, researchers discovered some interesting trends from their system of sensors, which they called MAAV (Measure Air quality, Annotate data streams and Visualize real-time PM2.5 levels). One homeowner discovered that the air pollution in her home spiked when she cooked with olive oil. So that motivated her to find other oils that produced less smoke at the same cooking temperature.

Another homeowner would vacuum and clean the house just before a friend with allergies dropped by, to try to clean the air of dust. But what she found out through the MAAV system is that she actually made the air much worse because she kicked up more pollutants with her vacuuming and dusting. Realizing this, she started cleaning the house much earlier before the friend would visit.

Participants would open windows more when the air was bad or compare measurements between rooms and avoid those rooms with more pollution.

“Without this kind of system, you have no idea about how bad the air is in your home,” Wiese says. “There are a whole range of things you can’t see and can’t detect. That means you have to collect the data with the sensor and show it to the individual in an accessible, useful way.”

Researchers also learned that circumstances that made the air pollution worse differed in each home. Vacuuming in the home, for example, would have different effects on the air quality. They also learned that if homeowners could visualize the air quality in their home, they always stayed on top of labeling and looking at the data.

Wiese says no known manufacturers make air quality systems for the home that allow residents to visualize and label the air quality in this way, but he hopes their research can spur more innovation.

The study involved engineering in collaboration with other University of Utah scientists, including biomedical informatics and clinical asthma researchers. It was funded as part of a larger National Institutes of Health program known as Pediatric Research using Integrated Sensor Monitoring Systems (PRISMS), launched in 2015 to develop sensor-based health monitoring systems for measuring environmental, physiological and behavioral factors in pediatric studies of asthma and other chronic diseases.

10 YEARS OF SUSTAINABILITY

Originally posted in @theU on Sept. 22, 2017.

By Amy Brunvand, Sustainability Librarian.

The University of Utah Sustainability Office turns 10 years old this year, and it is truly amazing to look around campus and realize how much has changed for the better in the past decade. Nowadays, there are campus vegetable gardens with ripe tomatoes and hives of buzzing bees, solar parking canopies that provide both power and shade, electric vehicles plugged into charging stations, crowds of students arriving on TRAX light-rail trains, tasty vegetarian and vegan options on offer at the cafeteria, water bottle refilling stations in most buildings, and plenty of recycling bins to divert waste from the landfill.

The curriculum has changed, too. Undergraduates can earn a number of sustainability-focused degrees and minors, while graduate students in any field can add an Interdisciplinary Graduate Certificate in Sustainability to their credentials.

Over the years, students, staff and faculty have all contributed to a vision of making the University of Utah a better place. In September, the Sustainability Office will celebrate these milestones and achievements with a Sustainability Showcase highlighting current programs and resources, and a special presentation by Dr. Vandana Shiva who advocates for traditional agriculture, and environmental and social justice issues worldwide.

Join us at the Sustainability Showcase on Friday, Sept. 29, 11 a.m.-2 p.m. on the Marriott Library Plaza for food, live music and fun activities. Later this fall, Dr. Vandana Shiva will present a public lecture at Libby Gardner Concert Hall on Saturday, Oct. 20, 7:30 p.m., as part of UtahPresents 2017-18 season. Tickets are available now.

1991-2006: Early Beginnings of Sustainability

Ten years ago, the transition to campus sustainability had barely begun, although a few major milestones laid the foundation. The first big sustainable change was a side effect of trying to cope with limited parking; in 1991, Commuter Services launched the Ed Pass program to give a UTA transit pass to every student and employee on campus. Not only did this encourage people to leave their cars at home, it helped expand Salt Lake City’s light rail network when enthusiastic transit riders from the U showed up at City Council meetings to press for construction of the Red Line TRAX, which opened in 2001.

In 1996, a biology professor named Fred Montague started an “unofficial” campus vegetable garden to teach students about his ideas for ecological gardening. That unofficial garden became the foundation of today’s Edible Campus Gardens, which teaches volunteers how to grow food, supports organic gardening curriculum and sells produce at the University of Utah Farmers Market. By 2006, the university had also constructed the Spencer F. and Cleone P. Eccles Health Sciences Education Building, the first LEED-certified building which incorporated efficient use of energy and water, waste reduction and consideration of human health in the building’s design, construction, operations and maintenance.

These efforts were significant, but they weren’t yet part of a unified drive to implement sustainability on campus.

2007-2014: The Sustainability Office Forms

Divergent efforts began to coalesce in 2007, with the formation of the Sustainability Office (then called the Sustainability Resource Center), underneath Facilities Management.

Something like the Sustainability Office doesn’t happen without visionaries. The idea was originally proposed by students, but it was City & Metropolitan Planning faculty member Craig B. Forster who led the effort to make the idea work. Forster, who became the first director, was a natural fit with sustainability. He was interested in facilitating interdisciplinary research and bridging the gaps between science and public policy. He also had a talent for bringing people together and was deeply involved with the local community. In the summertime, he was often seen at the Pioneer Park farmers’ market playing cimbalom (a kind of hammered dulcimer) with his Hungarian Táncház band.

With only one full-time staff member and some volunteers, the Sustainability Office got to work organizing recycling at football games, installing the first solar panels on campus, setting up a campus farmers’ market, making sure that sustainability was included in the Campus Master Plan and developing a student fee to support student-led sustainability projects through the Sustainable Campus Initiative Fund. On Earth Day 2008, University of Utah President Michael K. Young signed the American College & University President’s Climate Commitment, dedicating the university to achieving carbon neutrality by 2050. The year ended in tragedy, though, when Forster died in a hiking accident.

Despite the loss of Forster, the university persevered with a vision for making sustainability integral to its operations. In 2009, after a competitive nationwide search, architect and planner Myron Willson was appointed the next director of the office.

2014-2017: Sustainability is Integrated into Academic Affairs

In 2014, the Sustainability Office made another big change to adapt to the growing campus. Originally, the office was on the organizational chart under Facilities Management with the idea that university employees would take care of recycling, xeriscaping, transit passes and such.

But then an interesting thing happened. Students were getting more and more interested in sustainable change. They wanted to try out their ideas, and the campus was the most natural place for them to do so. With the Sustainable Campus Initiative Fund (SCIF) now up and running, grants were available for student-led sustainability projects. The university had become a living laboratory for sustainable change, and sustainability-focused courses had popped up in academic departments all over campus. With so much involvement in interdisciplinary research and learning, the Sustainability Office moved into Academic Affairs, and Associate Vice President for Faculty and law professor Amy Wildermuth was named Chief Sustainability Officer in 2014. Wildermuth added Adrienne Cachelin, Environmental & Sustainability Studies faculty to the team as the director of sustainability education to guide burgeoning sustainability education efforts across campus.

Under Wildermuth, the Sustainability Office also joined forces with the Global Change and Sustainability Center (GCSC), founded in 2010 by biology professor Jim Ehleringer to foster interdisciplinary sustainability research. Nowadays, under Director Brenda Bowen, Geology & Geophysics faculty, the 129 faculty affiliates of the GCSC represent nine colleges. The center supports graduate students through grants and fellowships, offers an interdisciplinary research seminar series, faculty networking opportunities, assistance for large interdisciplinary grants and core courses in the Interdisciplinary Graduate Certificate in Sustainability curriculum.

Sustainability is You: The Next 10 Years

Today, the Sustainability Office team includes fourteen faculty and staff members as well as numerous student interns and volunteers and continues to expands its scope. Though much progress has been made, sustainability is an ongoing effort, and there is still a lot of work to do.

This year, the Sustainability Office celebrates 10 years of dedicated efforts of faculty, staff and students from across campus. The next 10 years of sustainability at the university will be guided by those in our community who get and remain involved. We invite you to be part of this important work. Join us at one of our fall events to learn about ways you can help make the U a better place for all who live, work and play here.

Another Year in SCIF

Another Year in SCIF

By: Emerson Andrews, SCIF Coordinator.

One more academic year has passed us by, and as people get ready for their summer adventures, now is a good time to reflect on some of the wonderful work that students did this year through the Sustainable Campus Initiative Fund (SCIF). Since the creation of SCIF, the money available for projects has never been fully spent, however, 2017-18 marks a big change as all SCIF funding for this year was allocated to some awesome projects.

The following three projects are a small cross section of all the wonderful work that has happened through student energy and SCIF support this year. For detailed information about all SCIF projects, please stay tuned for the 2017-2018 SCIF Annual Report, which summarizes every project that was funded.

Burned Out – $262.14

  • This grant funded the construction of an interactive sculpture installation that lit up when viewers interacted with it on the second floor of the Marriott Library. This sculpture encouraged people to discuss energy usage, indirectly bringing awareness to carbon dioxide emissions created by power plants which generate electricity by burning fossil fuels. The piece consisted of black structures – evoking industrial facilities – and had handles placed at varying points, which viewers were encouraged to touch. Cranking the handle hard enough caused a certain portion of the sculpture to light up. All four handles must be turned by different people at the same time in order to see the entire piece light up. This piece encouraged people to engage with energy production, and both physically and mentally reflect our current global crisis.

Food Recovery Network Operations Coordinator – $4,953.05  

  • This grant funded the pay and equipment necessary for a Food Recovery Network Coordinator. The coordinator recorded food waste data and gave it to Dining Services so that Dining Services could adjust their production scheduling and eliminate unnecessary waste at pre-production. This data included up-to-date records of inventory and preferred foods for delivery based on student/client preference and acquisition. Additionally, this process provided a larger variety of foods while giving students and clients healthier alternatives to existing dry and canned food options. All of these objectives helped to reduce the amount of edible food waste in the university’s waste stream; recorded hard data with respect to specific aspects of the campus food systems, and provided hungry students with healthy food options.

Sustainable Tech for Design Build Bluff – $35,535.00

  • This grant funded the purchase and acquisition of appropriate sustainable technologies to be used on the Bluff Campus. These technologies increased energy and operations efficiency, specifically through the use of a solar PV array – arrangement of solar panels – on an existing building, and an earth block press and non-toxic insulation machine for future university building projects on the Bluff campus and throughout the region. These are all demonstrable technologies in an area that is a confluence of students and locals — both who could benefit from exposure to, and training in, the workings of these technologies. In addition to their practical applications on a regional scale, these operational improvements bring sustainable outcomes to a U of U remote campus.

These three projects reflect the power of the Sustainable Campus Initiative Fund to approach sustainability from multiple perspectives. SCIF truly allows students to experiment on the living, learning, laboratory that is campus through whichever lens they study. This ability is unique to SCIF and benefits everyone on campus.

RECYCLE GLASS ON CAMPUS

Emerson Andrews, Sustainable Campus Initiative Fund coordinator. Originally posted on Jan. 9 2017. 

Glass recycling has arrived at the University of Utah thanks to the combined efforts of three students, Facilities Management and the Sustainable Campus Initiative Fund, or SCIF.

Fifty bins will be placed in buildings during the beginning of the spring 2017 semester and available for use by students, faculty and staff. At least one glass recycling bin will be placed in all major buildings across campus with a few extra in high-traffic places like the Union and Marriott Library.

While taking Global Changes in Society, a course offered by the Global Change & Sustainability Center, GCSC, three environmental humanitiesgraduate students proposed a glass recycling pilot project. Jennifer Lair, Nicole Cox and Carissa Beckwith wanted to implement an on-campus glass recycling bin program utilizing the Momentum Recycling facility in Salt Lake City.

They took their idea from the classroom straight to Facilities Management and the Sustainable Campus Initiative Fund. Joshua James, the university’s campus recycling coordinator, provided both the support and knowledge to implement glass recycling on campus. He helped students develop a plan that could make glass recycling a continued service with space to grow.

“We had a great opportunity open up with Momentum making a glass recycling facility in town,” James commented.

Once the plan was in place, it was a matter of finding the money to pay for it. The students secured the support of both SCIF and the GCSC to raise the $10,000 necessary for the project. These funds were used to purchase bins, install them on campus and develop a schedule for collection and drop-off. This project illustrates the power of a resource like SCIF in the hands of students.

“The GCSC class provided us with the time, space and support we needed to propose and implement the glass recycling initiative on campus,” Beckwith commented. “SCIF funding was instrumental to kick-starting this project.”

If the bins work well, the glass recycling program will grow in the future. It is important to remember that glass can only be recycled in the glass recycling bins — glass in other recycling bins presents a hazard to custodial staff.

“It’s important to continue to develop the program. But in order to do that, people need to make sure that glass goes into the correct bin.” James continued, “Glass going into the normal recycling stream could cause a lot of problems.”

These bins are only big enough for faculty, students and staff to recycle glass acquired here on campus. If people would like to recycle their glass from home, there are two public drop-off bins: One bin is located by student housing in Fort Douglas, and the other is located just off of Guardsman Way.

“I hope that glass recycling on campus catches on quickly with students, staff and faculty,” Beckwith concluded. “It is an easy action that can provide a huge payoff for the planet!”

 

SEMINAR: GREENLAND ICE SHEET MAY HAVE LARGER THAN EXPECTED IMPACT ON SEA LEVEL

By: Liz Ivkovich, Sustainability Office.

New research suggests that the Greenland Ice Sheet is far less stable than current climate models predict, which could mean those models are severely underestimating potential sea level rise.

The ice sheet contains the equivalent of 24 feet of global sea level rise if it melts.

Joerg Schaefer, a paleoclimatologist at Columbia University’s Lamont-Doherty Earth Observatory, will present this new finding and why it matters at the GCSC Seminar Series on Jan. 17 from 4–5 p.m. in 210 ASB.

The Greenland Ice Sheet (GIS) is part of Earth’s cryosphere, the frozen water component of our climate system. The cryosphere plays a vital role in regulating planet temperature, sea levels, currents, and storm patterns. Over Earth’s billions of years, elements of the cryosphere have melted and re-frozen. Understanding how these elements have acted in geologic time scales and during prior periods of climate change enables scientists to model how Earth’s systems will react as the climate warms in the future.

Current climate models, including those developed by the Intergovernmental Panel on Climate Change, are based on the assumption that Greenland’s ice sheet had been relatively stable over the past several million years. The stability of the GIS is under debate. If the GIS was frozen in the past when natural ‘forcing’ (causes) warmed the globe, that means it could stay stable despite human-caused global warming. Unfortunately, Schaefer’s research finds direct evidence from bedrock underneath the ice that the GIS is more at risk of melting than scientists expected.

“We came up with the worrisome result that the Greenland Ice Sheet was actually rather dynamic under natural forcing, which basically immediately means our models overestimate stability with respect to ongoing climate change…” Schaefer explained. “[The prior melting] was due to periods of natural forcing. We will overtake this by anthropogenic forcing very soon, and we just don’t have an argument to expect that the Greenland Ice Sheet will not go again.”

Schaefer and his Lamont-Doherty Earth Observatory Cosmogenic Dating Group’s discovery is the result of groundbreaking direct evidence from rock underneath the ice’s surface. Schaefer said the researchers asked the rock a question: “Have you ever been exposed to open sky?”

The rock Schaefer is referring to is a sample of bedrock from several miles below the ice sheet, obtained in the early 1990s. It took researchers nearly five years to drill out these rocks; the deepest ice core recovered in the world at that time. The sample is so precious that Schaefer and his predecessors didn’t want to work on them until they knew that the research method would produce accurate results. Enter cosmogenic nuclide technique.

Cosmogenic nuclide technique counts the cosmogenic nuclides in the near surface of the rock. These isotopes are produced when extraterrestrial radiation—cosmic rays—trigger a reaction in rock. The reaction produces radioactive beryllium-10 and aluminum-26 isotopes.

“These nuclides are characteristic for cosmic rays, so whenever you measure the nuclides in excess, you know that it’s due to exposure to open sky,” Schaefer explained. “If you measure these nuclides underneath an ice sheet, you know that the ice was gone.”

Schaefer describes these isotopes as sisters that always occur and decay in a specific ratio to each other. Knowing this relationship enables the scientists to count how long the rock was exposed to open sky, and when it was covered again with ice. Though the process is theoretically simple, it is very complicated to measure. It yields an unprecedented direct record of how the ice has melted and refrozen in the past.

The instability of the ice sheet has implications for policy. Translating this, and other climate science research into governance, is what Schaefer calls the “biggest frontier in climate science.”

“Many of the scientific findings are robust and clear, and now the next step is we have to become much better in transferring that into real decisions,” Schaefer said.

Learn more at Schaefer’s lecture, “Ice sheets, glaciers and society: Past and present cryospheric change and its impact on society,” on Jan. 17 at 4 pm in 210 ASB.
