Wait your turn, cows. Cornell now milks the sun for energy. The university formally opened three additional solar farms in December that will generate large amounts of electricity and help the campus achieve its carbon neutrality goals.

“We’re making substantial, meaningful progress on Cornell’s Climate Action Plan – and one way is to obtain more electricity from solar power,” said Sarah Zemanick, director of the Campus Sustainability Office.

One of the new solar farms is located at Cornell’s Ruminant Center in Harford, New York – home to about 500 research cows and other farm animals. Sited on poor agricultural land, the facility, which opened Dec. 20, features 20 acres of 9,333 photovoltaic panels that annually will produce 3.2 million kilowatt hours and reduce greenhouse gas emissions by 610 metric tons.

The two other solar farms went live Dec. 30 at the Cornell Agricultural Experiment Station at Musgrave Research Farm in Ledyard, New York. The combined Musgrave East and Musgrave West facilities, each with 9,044 photovoltaic panels, will produce about 6.5 million kilowatt hours annually, reducing greenhouse gas emissions by 1,220 metric tons.

Microalgae create green fuel, reduce food insecurity [2016-11-21]  - Taken from the bottom of the marine food chain, microalgae may soon become a top-tier contender to combat global warming, as well as energy and food insecurity, according to a study by researchers associated with the Cornell Algal Biofuel Consortium, published in the journal Oceanography (December 2016). “We may have stumbled onto the next green revolution,” said Charles H. Greene, professor of earth and atmospheric sciences, and lead author of the new paper, “Marine Microalgae: Climate, Energy and Food Security From the Sea.” The study presents an overview to the concept of large-scale industrial cultivation of marine microalgae, or ICMM for short.  Read more.

Bacterial mechanism converts nitrogen to greenhouse gas [2016-11-18]  -  Cornell researchers have discovered a biological mechanism that helps convert nitrogen-based fertilizer into nitrous oxide, an ozone-depleting greenhouse gas. The paper was published online Nov. 17 in the Proceedings of the National Academy of Sciences. “The first key to plugging a leak is finding the leak,” said Kyle Lancaster, assistant professor of chemistry and chemical biology, and senior author on the research. “We now know the key to the leak and what’s leading to it. Nitrous oxide is becoming quite significant in the atmosphere, as there has been a 120 percent increase of nitrous oxide in our atmosphere since pre-industrial times.” Read more.

Moral values influence action on climate change

Two moral values most highly rated by liberals predict willingness to make lifestyle changes to avert climate change, according to Cornell research. The findings also suggest that a moral value rated more highly by conservatives may foster intention to act on climate change.

A new multidisciplinary study suggests moral values highly rated by liberals — namely, compassion and fairness — influence willingness to make personal choices to mitigate climate change’s impact in the future. Valuation of purity, which is highly rated by conservatives, also appears to have a positive effect, though not as pronounced as compassion and fairness. The other moral values of in-group loyalty and authority – both more highly valued by conservatives – were not associated with willingness to take action.

Those insights from a group of four researchers – Janis Dickinson, professor of natural resources; Poppy McLeod, professor of communication; Robert Bloomfield, the Nicholas H. Noyes professor of management and professor of accounting; and Shorna Allred, associate professor of natural resources – were published Oct. 19 in PLOS One. While prior research has investigated the relationship between moral values and environmental attitudes, this work extends this investigation to intentionality with respect to changes in environmental behavior.

Interim President Hunter Rawlings gave students credit for propelling the university into action at the President’s Sustainable Campus Committee annual summit Nov. 10.

“During my years as president – the first time – the students of Kyoto Now, now known as Climate Justice Cornell, pushed us – so you see this started with students really – pushed us to try harder to reduce greenhouse gas emissions,” said Rawlings in his keynote address.

Rawlings said Cornell students “show a tremendous awareness of sustainability issues … and they show a steadily increasing passion toward sustainability as part of their studies and, more importantly, as part of their lives.”

Soil scientist speaks on land degradation at COP22 [2016-11-10] - In a presentation to global leaders battling issues of climate change and feeding a burgeoning world population, Dawit Solomon, Cornell senior research associate in crop and soil science, explained food security solutions – such as adding biochar to poor agricultural soil – to combat Earth’s atmospheric warming.

Grant to aid study of microbes’ role in soil carbon cycle  [2016-11-10] - Microorganisms in the soil produce about seven times more carbon dioxide (CO2) every year than all human sources combined. Ideally, the release of CO2 from soils is balanced by CO2 consumed by plants. Very little is known about soil microbes or how they will respond to climate and environmental changes. A project led by Cornell researchers to better understand soil microbes and their role in the carbon cycle has received a three-year, $3.59 million grant from the U.S. Department of Energy.

Panel outlines action for campus carbon neutrality by 2035  [Cornell Chronicle 2016-11-2]  -  With a plan to harness the wind, sun, water and the Earth’s heat, a panel from the Senior Leaders Climate Action Group (SLCAG) explained to the Cornell community Oct. 31 how the campus could become carbon neutral by 2035. They stepped through the financial analysis and feasibility report that was released in October. “We need to heat and power a ‘Research I’ institution, and we are power hungry,” said Lance Collins, the Joseph Silbert Dean of Cornell Engineering and co-chair of SLCAG. He outlined Cornell’s carbon footprint challenges, which include designing a campus heating system that can accommodate Ithaca’s extreme weather conditions. The current low cost of fossil fuel makes it difficult to justify future renewable energy projects, Collins said, but the university aims to reduce campus energy demand and increase the number of high-performance buildings. As for fossil fuel energy sources, he explained, “The goal is to drive this to zero.” Read more.

New model suggests scrubbing CO2 from the atmosphere [Cornell Chronicle 2016-10-26] - New Cornell research suggests an economically viable model to scrub carbon dioxide from the atmosphere to thwart runaway, point-of-no-return global warming. The researchers propose using a “bioenergy-biochar system” that removes carbon dioxide from the atmosphere in an environmental pinch, until other removal methods become economically feasible and in regions where other methods are impractical. Their work appeared in the Oct. 21 edition of Nature Communications. Read more.

Colorado River’s dead clams tell tales of carbon emission  [Cornell Chronicle 2016-10-27] - Scientists have begun to account for the topsy-turvy carbon cycle of the Colorado River delta – once a massive green estuary of grassland, marshes and cottonwood, now desiccated dead land. “We’ve done a lot in the United States to alter water systems, to dam them. The river irrigates our crops and makes energy. What we really don’t understand is how our poor water management is affecting other natural systems – in this case, carbon cycling,” said Cornell’s Jansen Smith, a doctoral candidate in earth and atmospheric sciences. Smith is lead author of “Fossil Clam Shells Reveal Unintended Carbon Cycling Consequences of Colorado River Management,” published in the journal Royal Society Open Science, Sept. 28.  Read more.

Warming oceans imperil iconic marine species

Cornell Chronicle [2016-09-09]:

With a warming ocean along the East and West Coasts of the United States, many well-known marine species – important culturally and economically – face a dicey future, according to a new Cornell study in Oceanography magazine.

“Climate warming has been wreaking havoc with North America’s marine ecosystems,” said Charles H. Greene, Cornell professor of oceanography in the Department of Earth and Atmospheric Sciences. “The resulting demise of many of North America’s most iconic marine species provides yet another warning to society that a changing climate will leave future generations with an ocean much different than the one we grew up with.”

Although lobsters now thrive in the Gulf of Maine, continued rising temperatures, could soon lead to a disease outbreak that will decimate the Gulf’s lobster population. Greene points out that bacterial Epizootic Shell Disease, which thrives in warmer waters, has been steadily shifting northeastward along the New England coast and now has lobsters in the Gulf of Maine in its crosshairs.

With water temperatures rising, certain fish stocks are also increasingly stressed. “Cod stocks … like those in the Gulf of Maine, fare poorly under warming conditions, exhibiting … greater susceptibility to overfishing,” he said. …

Greene and Drew Harvell, professor of ecology and evolutionary biology, will be at the U.S. State Department’s Our Ocean conference Sept. 14-15 in Washington, D.C. The national conference focuses on the key ocean issues – marine protected areas, sustainable fisheries, marine pollution and climate impacts on the ocean. Harvell will present the film Fragile Legacy, about her biodiversity research and its relationship to Cornell’s Blachkas Glass Invertebrate Collection. Greene will run an exhibit displaying Wave Gliders – a robotic way to measure the health of the ocean – in the lobby of the State Department.
