New element tracking method a boon for geoscientists

Cornell Chronicle [2015-11-19]:

Geoscientists track how elements cycle across land, air and water to better understand climate change, ecological food webs and resources, plant nutrient cycling, water use and for forensics purposes.

But until now, they have only been able to parse inputs of such elements as carbon or nitrogen in a system when there are two sources. Yet many natural systems may have three or more interdependent sources, leaving researchers unable to separate inputs from one source to another, and hindering them from understanding how sources may interact with each other to affect overall carbon or nitrogen cycling in that system.

A Cornell study in the Nov. 4 issue of Nature Communications describes a new method that allows geoscientists to tease out the exact inputs from three different sources.

Cornellians travel to Paris for global climate summit

cop21 logoCornell Chronicle [2015-11-18]

Cornell researchers will travel to Paris in early December as part of the university’s delegation to the global climate change summit, COP. Even in the wake of the recent Parisian terrorist attacks, delegations from over 190 countries and more than 50,000 people from all over the world are expected to attend.

Participating in the 2015 United Nations Climate Change Conference – or COP21, for the 21st meeting of the Conference of the Parties – will be Robert Howarth, the David R. Atkinson Professor in Ecology and Evolutionary Biology; Johannes Lehmann, professor of soil science; Karen Pinkus, professor of romance studies and comparative literature; and Allison Chatrchyan, director of Cornell’s Institute for Climate Change and Agriculture. Chatrchyan, Howarth, Lehmann and Pinkus are fellows at Cornell’s Atkinson Center for a Sustainable Future.

Also in Paris, Brian Davis, assistant professor of landscape architecture, will address the Water, Megacities and Global Change conference, a concurrent meeting.

“COP21 is critical. The world is on a trajectory to warm to a dangerously high 1.5  degrees Celsius within 15 years and to 2 degrees Celsius within 35 years, unless we take urgent action now to reduce greenhouse gas emissions,” said Howarth, who will focus on methane’s role in global warming.

Howarth will speak to international unions, as well as to Friends of the Earth Europe; Food and Water Watch; and

“The scientific community of the world is united on these points, and the world’s religious leaders – including the Pope and the Dalai Lama – have given this message their full moral authority. Now is the time to act. Paris is the place where this must happen,” Howarth said.

Pinkus will also attend workshops and meet with other humanities scholars at Paris West University Nanterre La Défense. Pinkus will reflect on the conference for several publications, as she is especially interested in geoengineering.

“I know this may sound strange coming from a literature professor,” she said. “Given that the shift to renewables will not happen fast enough, I believe we may be headed toward some combination of solar radiation management and carbon dioxide removal. If we are going to further geoengineer the planet, we need philosophical reflection and critical thought to guide the technological aspects of our work.”

On Dec. 3, Cornell, along with the United Nations Development Programme, the French Institute of Research for Development, and the International Food Policy Research Institute, will host an official side event for world leaders, on “Climate Change, Agroecology, Nutrition and Food Security,” at which Lehmann will deliver a talk, “Food Security Interventions for Mitigating Climate Change in Sub-Saharan Africa.” Chatrchyan will moderate the panel.

Additionally, Chatrchyan and Lehmann will be available at the Cornell exhibit in the main United Nations conference area, showcasing the university’s breadth of research and outreach capacity on climate change and agriculture around the world.

On Dec. 1, Davis will present his research on water management in Brazil, in which his students – along with students from the University of São Paulo – have been developing environmental models and maps, river design and public space projects to study alternative scenarios for water detention structures in the city.

Move toward greater sustainability a priority, says Garrett

Cornell Chronicle [2015-11-12]:

In her remarks at the President’s Sustainable Campus Committee fall summit Nov. 12, President Elizabeth Garrett underscored the university’s commitment to addressing climate change by announcing formation of the Senior Leaders Climate Action Group.

The group – chaired by KyuJung Whang, vice president for infrastructure, planning and properties; and Lance Collins, the Joseph Silbert Dean of Engineering – will be composed of deans, vice presidents and other campus leaders to focus on improving current climate trends by advancing public policy on climate change and spurring innovative, cross-disciplinary solutions.

“Meeting the energy, environmental, economic and social needs of the present – without compromising the ability of future generations to do the same – is one of the critical challenges of our time, not only for New York and the country, but for the world,” Garrett said. …

Cornell should use its strength in education to reduce global warming and climate change, she said: “We should be focused on having global impact in addressing this problem through our teaching and our research in a way that changes the world.”

Garrett mentioned an increase in the types of sustainability classes and programs the university will offer. “We will be highlighting our outstanding educational programs in this arena as we go around the world seeking the best students for Cornell,” she said. “This focus appeals to some of the very best students in the country who need to understand that if they can come to Cornell they can make a difference they cannot make anywhere else.”

Business leaders will bring politicians to the table on climate change

David Wolfe in The Hill [2015-11-02]:

“… Farmers are on the front lines of climate change, and while they may not all call it by that name or agree about the causes, the vast majority recognize they are the first generation of farmers, ever, who cannot rely on historical weather patterns to tell them when to plant, what to plant or how to grow it.

“Many farmers have told me that if the changes were as straightforward as a few more days of heat stress or drought each year, they could plan around that. But the changes are all over the map. One year, farmers may face record-breaking spring rain that delays planting. The next year could bring a record-breaking drought near harvest. Another year, their fruit crops bloom weeks early and get blasted by a spring frost. As a result of this unpredictability, many are hedging their bets, staggering planting dates, planting a wider range of crops and considering investments such as irrigation or drainage systems.”

Cornell launches Crowdfunding Campaign for Climate Smart Farming

The Harvest Campaign for Climate Smart Farming, ending on Giving Tuesday (December 1), celebrates the bounty that farmers in the Northeast produce, all while facing increasing challenges and risks from extreme weather and climate change.

Please spread the news about the campaign and consider a donation to help us develop a suite of tools, best management practices, and forums – all built for farmers, based on their needs for more regionally-specific, and production-specific climate resiliency information.
