Climate change’s heat – not cold – is the real killer

Chill with impunity through this winter’s extreme cold – and brace for the next summer heat wave, when fiery temperatures and air pollution conspire to fill hospitals and morgues.

That’s the advice from a team of climate-change researchers who studied 170 million hospital admissions and 8 million deaths (season by season, day by day, for 10 years) in Germany before issuing a report with global implications.

“We show that extreme heat events have a highly significant and largely adverse impact on both hospitalizations and deaths, whereas extreme cold seems to have a negligible real-world impact on population health,” said Nicolas Ziebarth, assistant professor of policy analysis and management in Cornell’s College of Human Ecology.

Ziebarth published “The Short-term Population Health Effects of Weather and Pollution: Implications of Climate Change” (as a December 2013 IZA working paper) with Maike Schmitt, Darmstadt Technical University, and Martin Karlsson, University of Duisburg-Essen. Ziebarth is also affiliated with the German Institute for Economic Research and the Institute for the Study of Labor (IZA).

Keith Tidball

Keith Tidball

Keith Tidball, senior extension associate in the Department of Natural Resources and state program leader of Cornell Cooperative Extension’s New York Extension Disaster Education Network (NY EDEN), has been named a U.S. Department of Agriculture (USDA) National Institute for Food and Agriculture (NIFA) 2014 visiting scholar. Tidball, whose work focuses on disaster readiness, response and resilience, will work jointly with NIFA’s Division of Family and Consumer Sciences and NIFA’s Center for International Programs.

Visiting scholars are selected from faculty who are actively engaged with the NIFA-funded Extension Disaster Education Network and interested in conducting work that bridges domestic and international efforts in disaster preparedness, response and recovery education. Tidball will link existing EDEN efforts to other NIFA initiatives and programs, Cooperative Extension Regional Development Centers, emergency preparedness, response and recovery programs of other federal agencies, and international disaster education efforts.

During his appointment, Tidball will work to further integrate EDEN’s national and New York state work with the new Cornell Institute for Climate Change and Agriculture and similar NIFA funded initiatives around the country, and he will help the Philippines launch its Extension Disaster Education Network.

KyuJung Whang, Cornell vice president for facilities, has been named to the board of directors of the Association for the Advancement of Sustainability in Higher Education (AASHE).

AASHE was founded in 2005 to coordinate and strengthen campus sustainability efforts and to serve as the first North American professional association for campus sustainability. The organization provides resources, professional development and support to administrators, faculty, staff and students in such areas as education, research, governance and operations.

During Whang’s seven years at Cornell, the university has completed a Climate Action Plan, created an on-campus sustainability advocacy and leadership group, and developed policies mandating LEED rating of all new buildings. Whang is involved in the design and construction process for building the Cornell NYC Tech campus on Roosevelt Island in New York City that will feature a net-zero energy building.

Faculty Senate urges fossil fuel divestment

By a vote of 46-13-2, the Cornell University Faculty Senate adopted a resolution Dec. 11 calling for the university to divest its $5.7 billion endowment from the top 200 fossil fuel-holding companies.

The resolution, “Cornell Investment and Divestment Strategies for a Sustainable Future,” also calls for Cornell to revise its Climate Action Plan to set a goal of carbon neutrality by 2035. In 2009 the university pledged to reach carbon neutrality by 2050.

Cornell’s faculty is the first in the Ivy League to pass a resolution calling for divestment, and many professors believe the symbolic resolution will foster dialogue, according to a statement released by faculty senators.

“It is our responsibility to act together to strongly encourage the governmental actions that are needed to address the rapidly approaching climate catastrophe,” said David Shalloway, the Greater Philadelphia Professor in the Department of Molecular Biology and Genetics and a co-sponsor of the resolution with 37 faculty members in 21 departments. “The adoption of the resolution by the Faculty Senate demonstrates moral courage that I hope will inspire similar actions at other educational institutions.”

Some of the resolution’s co-sponsors research climate change and adaptations to it. “Cornell was founded as a land-grant institution with a mission to translate our research into real-world solutions,” said co-sponsor Robert Oswald, professor of molecular medicine. “That is precisely what we are trying to do here.”

The Faculty Senate’s resolution followed a spring 2013 Cornell Student Assembly (SA) resolution that called for full divestment from fossil fuel holdings by 2020. The Graduate and Professional Student Assembly tabled a similar resolution.

Student energy group saves Cornell $35,000

The Cornell Energy Corps recently launched a campaign on the Indiegogo online fundraising platform to support energy auditing training, purchase auditing equipment and send team members to an energy efficiency conference.

The Cornell Energy Corps recently launched a campaign on the Indiegogo online fundraising platform to support energy audit training, purchase auditing equipment and send team members to an energy efficiency conference.

By replacing 61 incandescent light bulbs at Mann Library with CFL bulbs, Energy Corps, a student organization on campus helped the university save $600 over seven years. That was in spring 2012, when Energy Corps was founded by Sheila Garcia ’13, Mike Gardo ’14, Raksit Pattanapitoon and Jacob Reisch ’14.

Since then, Energy Corps has worked on 10 projects on campus that are expected to save $35,077 in energy and bulb-replacements this year –  $12,700 of that from avoided energy costs in the past fiscal year. This equates to $245,539 in savings over the next seven years.

Energy Corps also recently launched a campaign on Indiegogo, an online fundraising platform. In the first week, they raised more than $1,000, 10 percent of their goal. This money will be used for energy auditing training, to purchase auditing equipment and to send team members to an energy efficiency conference.

Book links food security to political stability

Food Security and Sociopolitical StabilityWhile drought-withered crops and starving livestock make cover stories, policymakers’ actions taken now to address “food security stressors” ultimately could have more impact worldwide than “biophysical drivers” like climate change and water scarcity.

That is the contention of a new book edited by Cornell’s Christopher B. Barrett, “Food Security and Sociopolitical Stability” (Oxford University Press, 2013).

The book points to a surge of urban food riots in low- and middle-income countries when food prices spiked in 2008 and 2011 – and cautions that the most destabilizing effect of higher food prices might be induced competition for land, water, fisheries, even animal and plant genetic material, any of which can spark violence.

An analysis of sales and rates for 9,000 hotels shows a net neutral effect for the hotel industry’s efforts to implement sustainability. The Cornell study concluded that the hotel industry’s fears of losing business due to implementing “green” operations is unfounded. However, on average, hotels also don’t see a revenue boost – or loss – from going green.

The study, “Hotel Sustainability: Financial Analysis Shines a Cautious Green Light,” by Howard G. Chong, assistant professor of economics and sustainability, and Rohit Verma, professor of service operations management, both in Cornell’s School of Hotel Administration (SHA). The study was published by the Cornell Center for Hospitality Research and presented Oct. 18 at the 2013 Sustainability Roundtable at the SHA.

Cornell Tech designed ‘for next century’

Rendition of what the Cornell NYC Tech campus will look like.With its innovative approach to sustainable design, the new Cornell NYC Tech campus on Roosevelt Island will be more than another ivory tower, as its forward-leaning design has innovative building technologies.

Some of the sustainable strategies include: optimal building orientation to maximize photovoltaic performance, efficient geothermal heating and cooling systems, high-performance building envelopes, daylight harvesting to limit the use of electric lighting, efficient lighting systems that use the latest proven technology and controls, and possible passive house criteria for residential towers. The first academic building, for example, will consume ultra-low energy and use geothermal heat pump heating and cooling, and energy from solar photovoltaic panels.

While the campus will take advantage of its natural habitat by incorporating rain gardens, green roofs and reforestation, it will also take measures to protect against any tidal surges caused by rising sea levels or future storms such as Hurricane Sandy.

“We believe global warming is real,” said Kyu-Jung Whang, Cornell vice president for facilities services. Over the next few decades the current 500-year flood level could replace the 100-year flood level, he said. “In addition to raising the level of the site, we are using the natural topography of the island, where there is a ridge down the center, to place the entry points of all future buildings on campus,” he added.

On the day the United Nations announced that global carbon dioxide levels had reached their worst levels in history, Cornellians reported that the strategies to reduce the university’s carbon footprint are working, but the campus has a long road to meet its carbon neutrality goals by 2050.

Cornell President David Skorton spoke to about 130 faculty, students and staff members Nov. 6 at the third annual President’s Sustainable Campus Committee fall summit, which included sessions for small working groups addressing Climate Action Plan priorities and the announcement of the winners of the Cornell University Partners in Sustainability Award.

In discussing campus efforts, Skorton said that easy-to-fix strategies are in place, but hard decisions are ahead.

“As bold as [going coal-free has] been, it’s not obvious what the next three or four or five bold moves are going to be,” he said, urging the sustainability leaders to find ways to achieve net-zero carbon emissions by 2050. Cornell has reduced carbon emissions by 32 percent since Skorton signed the Presidents Climate Commitment in 2007. The next steps in significantly reducing our carbon footprint won’t be easy, he said.
