Heat and Drought Extremes Likely to Stress Ecosystem Productivity Equally or More in a Warmer, CO2 Rich Future 5/18/2015

Geography Professor Chris Williams authored this article, which begins, "Recent heat waves and droughts have caused large-scale reductions in ecosystem carbon uptake around the world (Ciais et al 2005, Allen et al 2010, Zhao and Running 2010, Schwalm et al 2012). Extremes of this nature are expected to intensify with global warming (Easterling et al 2000), raising concerns about increased ecosystem stress, reduced biospheric productivity, and carbon cycle feedbacks that beget further warming (Luo 2007, Reichstein et al 2013). But before today's responses can be used to infer likely future impacts it is important to examine how ongoing global environmental changes may alter the sensitivity of the carbon cycle to climate and thus modify the impacts of heat waves and droughts in the future."

Clark University student researchers receive Marsh-Mosakowski NOAA Fellowships

Three Clark University students have been named 2015 Marsh-Mosakowski NOAA Fellows and soon will embark on summer internships to conduct ecological research alongside esteemed scientists in Maryland and Hawaii.

Scientists and managers with NOAA are partnering for a fourth year with Clark University to offer qualified undergraduate students paid summer field internships in NOAA labs and offices, working in fields such as applied ocean and atmospheric science, policy, and science communication. Each student is overseen by a NOAA scientist or manager and advised by a Clark faculty mentor.

The 2015 Marsh-Mosakowski NOAA Fellows are:


Saira Khan '17 is a Geography and an International Development and Social Change major who will work in Hawaii on NOAA'S Sentinel Site Program and Habitat Blue Print: From observation to stewardship. Her Clark faculty mentor is Professor Christopher Williams of the Graduate School of Geography.


Katherine Landesman '16 is a Global Environmental Studies major, with a Peace Studies concentration, whose NOAA Project will be in Hawaii working to develop bathymetric and benthic habitat data and products derived from WorldView-2 satellite imagery to support fisheries management in Timor-Leste, Hawaii. Professor Deborah Martin of the Graduate School of Geography will serve as faculty mentor.


Daniela Reyes Saade '17 is majoring in Geography and Economics and will spend the summer in Maryland providing socioeconomic support for the Office of National Marine Sanctuaries. Her faculty mentor is Professor James McCarthy of Clark’s Graduate School of Geography.

For more information about Clark's NOAA Internship Program, contact Robert J. Johnston, Director of the George Perkins Marsh Institute at 508.751.4619 or Jim Gomes, Director of the Mosakowski Institute for Public Enterprise at 508.421.3872.

Climate Change Teachers at Clark: Gird for the Long Haul

Worcester Telegram & Gazette 3/26/2015

"Efforts to slow changes in the climate that will have harmful ramifications throughout the world will have to continue for many generations, climate researcher Susanne C. Moser [Ph.D. '97] said Thursday at a daylong Climate Change Teach-in at Clark University. ... Christopher A. Williams, an associate professor of geography and environmental sciences at Clark, said there is no doubt that the greenhouse gases many scientists believe are changing the climate are building up in the atmosphere. ...One of the chief organizers of the teach-in was Sarah D. Buie, professor of visual and performing arts and senior associate at Clark's Higgins School of Humanities." More »
