Earth Week 2017

When we imagine the place where we live, we often think of our city, our state, or even our country. But Earth is also our home. We need the planet for more than it needs us. Activist and scientist Vandana Shiva reminds us, “You are not Atlas carrying the world on your shoulder. It is good to remember that the planet is carrying you.” In celebration of our home, the University of Utah will host Earth Week 2017 from April 10-14. The events of the week invite us to connect to our home through education and volunteerism. Join the festivities!

Earth Week is hosted by the Sustainability Office, ASUUthe Environmental and Sustainability Studies Leadership Committee, and U of U Tree Campus USA.

NAVIGATING UNCHARTED WATERS: HOW THE HUMANITIES CAN GUIDE THE WAY

Bianca Greeff, Graduate Assistant

A man lies on a dismasted, rudderless fishing boat. He appears unimpressed by the sharks loitering off the port, and oblivious to the ship faintly on the horizon. This painting, “The Gulf Stream” by Winslow Homer, has been interpreted several times since its creation in 1899. Now, in our current climate chaos, Homer’s depiction of a shipwreck takes on a new meaning.

“Shipwreck captures both the moment of extreme danger, and the potential for rebuilding afterwards,” explained Jeffrey McCarthy, director of the University of Utah Humanities Program. “Shipwreck is an interesting symbol for us in this moment of a distressed and chaotic climate.”

McCarthy will discuss the symbol of shipwreck, the paintings of Winslow Homer, and point to Joseph Conrad’s “Heart of Darkness” as a way to illuminate the humanities’ crucial role in understanding human relationships to the ocean and our climate future at the GCSC Seminar Series on Tuesday, April 4 from 4-5 p.m. in 210 ASB.

The ocean is essential to life on earth. It covers over 70% of our planet’s surface, and plays a fundamental role in shaping climate zones—even in places hundreds of miles inland. The ocean regulates earth systems, supplies living and non-living resources, and provides social and economic goods and services. Most of the oxygen in the atmosphere came from the ocean.

The ocean is the planet’s largest carbon sink. As it absorbs 26% of all CO2 released from fossil fuels, the chemistry of seawater is changing. The ocean has also absorbed 90% of atmospheric heat trapped by greenhouse gasses, which is increasing ocean temperatures. As life in the ocean changes, life on land will change too.

The ocean is less predictable, and less inhabitable for humans than its terrestrial counterparts. As we are entering a climate where there will be less predictability, analyzing seascapes can provide a way “to get our heads around what it means to occupy a space that is given to flux and uncertainty,” explained McCarthy.

“Environmental literary studies, and environmental studies more broadly, has been largely terrestrial,” McCarthy explained. “It is time to expand our notion of the planet we occupy to include not just the green parts, but also the blue parts.”

Art is a powerful addition to the data on climate change. By capturing how a culture responds to moments of uncertainty and risk, art shows the human-scale of climate change. In his talk, McCarthy will explore how cultural analysis of art can be a tool for understanding the past and navigating future crises.

“Art can remind us who we are, and who we want to be,” McCarthy concluded. “There is hope and beauty with art. We could all use more of both.”

WHICH WAY WILL WE TIP?

By: Liz Ivkovich, Sustainability Office.

Tipping Point, def.: the critical point at which a change becomes unstoppable.

Earth is undergoing an alarming series of changes due to human impacts. Warming climatewater shortagesincrease in infectious diseases, and loss of biodiversity. These changes and others are converging into a rapidly approaching tipping point for Planet Earth. What individuals, groups, and policymakers do in the next 10-20 years will determine which way we will tip, and what kind of future the next generation of all Earth’s species will have.

On Tuesday, Feb. 28, 4:00-5:00 p.m., Anthony Barnosky will present on the Earth’s tipping points and their implications for political and personal action at the Global Change and Sustainability Seminar Series. The lecture will be held in 210 ASB.

With years of research on past tipping points in Earth’s ecological history, Anthony Barnosky, paleoecologist from Stanford University, focuses his efforts on activating humans to tip towards environmental sustainability.

“What I have done is use the fossil record to understand how the Earth system responds to big changes, unusual changes,” Barnosky said. “It inevitably took me into thinking about some of the big changes that people are causing to the planet today.”

It is difficult to write about Barnosky’s research without sounding apocalyptic. He agrees that this is heavy stuff; however,  he wants people to know that their individual and local actions are meaningful.

“The sorts of issues that I talk about are very weighty, global issues,” Barnosky said. “People often throw up their hands in despair. But the reason these are big issues is that 7 billion people are doing things in a certain way. So, it really does all start with the individual. The cumulative actions of 7 billion individuals are enormous.”

Barnosky hopes the tipping point for Planet Earth won’t be catastrophic change, but rather large-scale social action. In this tipping point, 7 billion people use the knowledge, technology, and resources available to act in more sustainable ways. This vision of positive social action has driven Barnosky into conversation with policymakers.

In 2012, the governor of California approachedBarnosky to turn his Nature paper on Earth’s sixth mass extinction into a scientific consensus statement. The governor was able to use the consensus statement, which was signed by more than 500 scientists, to advocate for positive action towards avoiding a tipping point.

Barnosky also had advice for other scientists about how to effectively collaborate with policymakers.

“It’s not just walking into a policy maker’s office and pronouncing what the science says,” Barnosky concluded. “Working with policymakers means actually asking what are their needs are as far as science. Developing a dialogue is very important so that you understand where they are coming from, and they understand where you are coming from.”

CONNECTING THROUGH CREATIVE EXPRESSION

By: Bianca Greeff, Graduate Assistant.

Constructed out of old farming equipment, a rusted silhouette of a tree stands above the other vegetation. Nestled in the branches sits a bee nest. This nest creates space for pollinators specific to the Bonderman Field Station at Rio Mesa to thrive, provides researchers the opportunity to study the species, all while reminding the community of the rich ranching history of the area. This restorative sculpture, “Supporting Structures” was constructed by Wendy Wischer, assistant professor in the University of Utah’s Department of Art & Art History, in 2016.

Wischer will demonstrate the ways creative expression like “Supporting Structures” can engage individuals and communities with scientific data, and foster a connection to a place at the GCSC Seminar Series on Tuesday, Jan. 31 from 4-5 p.m. in 210 ASB.

“Recently we have been seeing more research and publications in articles and books describing the significance of the arts and how they can assist with environmental concerns,” Wischer said. “The arts are important in tackling our challenges with climate change, and sustainability as a whole.”

In her presentation, Wischer will share how her work has progressed from a symbolic practice representing the environment’s intrinsic beauty, to an activist approach designed to ignite action on environmental issues. Wischer hopes her work will create an emotional experience for the viewer, inspiring them to take personal or collective steps to maintain environmental integrity.

“It is usually our emotions that motivate us to act,” Wischer said. Those actions could “be anything from changing personal behaviors to advocating for shifts in policy.”

From joining forces with local communities and community organizations, to working alongside other University of Utah professors, collaboration is a crucial component of Wischer’s creative process. This collaboration helps Wischer engage people in social and environmental issues through her art.

“With socially engaged artwork, there are blurred lines in terms of what is art, and what is activism,” Wischer said.

In a current project along the Jordan River, Wischer is collaborating with an ecologist from the U.S. Fish and Wildlife Service, the Jordan River Commission, West Valley City, and members of the local community. The Jordan River has recently been a site of restoration. The parkway trail, garbage clean-up, and planting has made the river a great place to spend the afternoon (or the day, if you travel the entire 51 miles of the river).

Wischer is in the process of constructing sculptural elements that will help prevent bank erosion, and offer community residents a place to sit together. This restorative artwork along the bank will provide a tangible way to connect with the place, a connection that Wischer believes is vital for sustainability.

“What is really going to allow initiatives along the Jordan River to become sustainable is when the community feels connected to the river,” Wischer explained, “and they become natural stewards of the place.”

Wischer hopes her work can foster those connections that will help the Jordan River restoration thrive.

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.
