By the end of this century, the temperature of Oneida Lake – New York state’s largest interior lake – will likely be higher by about 6 degrees Fahrenheit. This would be enough to remove oxygen from its bottom waters, alter its species composition and eradicate its remaining cold water fish species, report Cornell researchers in the journal Ecological Modelling.

With an area of about 80 square miles, Oneida serves as the centerpiece of a large watershed. Prevailing west-northwesterly winds cause its shallow waters to mix frequently through the ice-free months. Between mixing events, the lake’s surface water warms and becomes less dense then the colder bottom layers. Large temperature differences between the surface and bottom layers result in strong stratification, and winds are needed to induce mixing.

As the climate changes, the temperature difference between the layers is expected to increase and last longer. By 2099 Oneida Lake could see an additional 61 consecutive days of stratification, according to the researchers’ projections.

Public warmer on ‘climate change’ than ‘global warming’

Cornell Chronicle [2015-02-16]:

Stop someone on the street in the storm-battered Northeast (or Northwest or just about anywhere in between) this winter. Ask about “global warming” and you’d better be prepared for a heated debate. Ask about “climate change” and cooler heads may prevail.

The American public responds differently to questions about “climate change” and “global warming” – even while the media often conflate the two – a new study by Cornell and University of Southern California researchers reveals.

“A key finding is that the public perceives more scientific agreement on the issue of ‘climate change’ than ‘global warming,’” reports Cornell’s Jonathon Schuldt, who led the study examining a survey of 2,000 American adults from the comfort of his Department of Communication office (not from a snow-covered street corner). “Recent studies suggest that perceiving a scientific consensus is an important predictor of people’s support for new regulations that address the problem.”

‘Megadrought’ likely for western U.S. by end of century

Cornell Chronicle [2015-02-15]:

The consequences of climate change paint a bleak picture for the Southwest and much of America’s breadbasket, the Great Plains. A “megadrought” likely will occur late in this century, and it could last for three decades, according to a new report by Cornell and NASA researchers in the journal Science Advances (Feb. 12), an online publication of the American Association for the Advancement of Science.

“The results were striking. As a society, we’ve weighted the dice toward megadrought. Data clearly point to a high risk in the Southwest and Great Plains, as we continue to add carbon dioxide into our atmosphere,” said Toby Ault, Cornell associate professor of earth and atmospheric sciences. “However, if we manage to get serious about lowering greenhouse gases within the next 10 years, we could face a lower risk.”

With a drier future and higher regional temperatures amplifying possible late-century droughts, the situation presents a major adaptation challenge for managing the region’s water needs, explains Ault, who along with lead author Benjamin Cook and Jason Smerdon, both of NASA, published their new study, “Unprecedented 21st Century Drought Risk in the American Southwest and Central Plains Drought Risk in Western North America.”

Skorton speeds campus carbon neutrality goal to 2035

Cornell Chronicle [2015-01-29]:

Cornell President David Skorton today released the report of the Climate Action Plan Acceleration Working Group (AWG), which recommends actions the campus should take to become carbon neutral by 2035.

“Nearly eight years ago, in response to the growing challenge of global climate change, I signed the American College and University Presidents’ Climate Commitment, pledging that Cornell would develop a plan to achieve climate neutrality, starting on our Ithaca campus, by 2050,” said Skorton in a statement. “Today, I again formally recognize the need to accelerate our efforts by embracing the goal of becoming carbon neutral by 2035.”

Skorton explained that his decision to hasten the date was advocated by a December 2013 Cornell Faculty Senate resolution that called for an accelerated timetable to achieve campus carbon neutrality.

Cornell Media Relations Office [2015-01-21]:

A team of scientists led by Cornell University Earth and Atmospheric Sciences researcher Michael Willis, has published a new paper showing for the first time that meltwater from the surface of an ice cap in northeastern Greenland can make its way beneath the ice and become trapped, refilling a subglacial lake. This meltwater provides heat to the bottom of the ice sheet.

These groundbreaking findings provide new information about atmospheric warming and its affect on the critical zone at the base of the ice. The warmth provided by the water could make the ice sheet move faster and alter how it responds to the changing climate.

The research is detailed in a new paper published online by the journal Nature on Jan. 21. The paper was written by Willis, who is also an adjunct faculty member in the geological sciences department at UNC-Chapel Hill’s College of Arts and Sciences, along with co-authors Bradley Herried, Polar Geospatial Center, University of Minnesota; Michael Bevis, School of Earth Sciences at Ohio State University and Robin Bell, Lamont Doherty Earth Observatory at Columbia University.

Students form nucleus for sustainability alliance


sustainability alliance meeting

Courtney Koelbel ’15, representing Cornell University Sustainable Design, reads suggestions Dec. 6 on possible governance procedures in the developing sustainability alliance.

Cornell Chronicle [2014-12-16]:

Passionate about strengthening sustainability, battling climate change and improving a polluted world, Cornell students packed a large Warren Hall meeting room Dec. 6 to begin forming an alliance of more than three dozen campus sustainability groups.

Over 100 students from across campus representing about 40 clubs congregated to contemplate strategy to link groups under one umbrella organization. “Our main purpose is uniting the [large variety of sustainability] clubs … We have already a huge presence on campus, so there’s something to be said about collective organizing,” said Emma Johnston ’16, co-president of Cornell Sustainability Hub.

Organizers of the new sustainability alliance discussed governance, the resources it may provide, how the group will help engage with nonmember students and a framework for communications. As individual clubs focus on various projects, the umbrella group – similar in scope to a sustainability congress, with representatives from each club – intends to organize itself by holding meetings and communicating with each other via social media.
