Climate Engineering: Future Guiding Principles and Ethics

Thursday, December 4
11:30 am – 12:30 pm
121 Cannon House Office Building

The Ecological Society of America will cosponsor a briefing on climate engineering featuring perspectives from former House Science and Technology Chairman Bart Gordon and two scientists. Climate engineering—also known as geoengineering—is the deliberate, global-scale manipulation of Earth’s climate system. Climate engineering opens our planet to possible hazards and unknown consequences. In order to manage risks and limit experiments with trans-boundary implications the international scientific community is developing a framework of guiding principles and ethics—encompassing the potential social, ecological, and economic effects.

The Honorable Bart Gordon, Former Chair of the House Committee on Science and Technology
Dr. Michael C. MacCracken, Climate Institute
Dr. Eugene S. Takle, Iowa State University
RSVP by December 1 (space is limited):

The Ecology of Zoonotic Diseases

On April 23, 2013, the Ecological Society of America sponsored a congressional briefing on the ecology of zoonotic diseases. The briefing highlighted the various environmental factors that can contribute to the spread of several prominent animal to human diseases.Presentations were given by Robert Parmenter, Director of the USDA Valles Caldera National Reserve Scientific Services Division and Gregory Glass, Professor at Johns Hopkins School of Public Health and Director of the Alabama Southern Research Institute’s Global Biological Threat Reduction Program.

Parmenter and Glass answer questionsDiseases discussed in Parmenter’s presentation included malaria, Lyme disease and hantavirus, a rodent transmitted disease, which has gained prominence in the New Mexico region where he resides. Parmenter explained that some diseases require vectors (usually arthropods like ticks or fleas) while others can be directly transmitted from a host (like the rodent-human spread of hantavirus). He also elaborated on the various ecological conditions that influence zoonotic diseases, such as precipitation and temperature.

Glass talked about the sources of environmental and health data. Multiple federal agencies make detection, monitoring and research of zoonotic diseases possible.  These include the National Aeronautics Space Administration, the National Oceanic and Atmospheric Administration, the United States Geological Survey, the Centers for Disease Control, the Environmental Protection Agency, the Departments of Defense, Agriculture and Homeland Security and the US Agency for International Development. Glass also highlighted ways in which ecologists can help predict future zoonotic disease outbreaks and how climate change is likely to affect the distribution of Lyme disease.

The briefing was hosted by the House Science, Space and Technology Committee.

Using Science to Improve Flood Management

On November 2, 2011, ESA sponsored a congressional briefing: “Using Science to Improve Flood Management.” Emily Stanley (University of Wisconsin, Madison) and Jeff Opperman (The Nature Conservancy, Ohio Field Office) addressed the function of floodplains and managing rivers as systems and for multiple benefits. 

Emily Stanley’s presentation focused on the work of rivers and the function of floodplains.  Industry, transportation, and recreation all constitute work done by rivers.  Less well known and valued is the work done by floodplains, responsible for such desirable services such as flood attenuation, fish production, improved water quality and groundwater recharge.  Stanley noted that aging US levee and other infrastructure provide an opportunity to move beyond structural flood control and take greater advantage of the functions of floodplains.

Jeff Opperman’s presentation focused on the logic of managing rivers as a system and for multiple benefits. These include risk reduction for people and infrastructure as well as benefits such as water storage during droughts and increased fisheries production.   Opperman said that because the Mississippi River is managed as a comprehensive system, the recent flood was far less damaging than that of 1927 even though a greater volume of water passed through the system in 2011.  Opperman also pointed to the success story of California’s Yolo Bypass, which has reduced flood risk while increasing goods and services.

Climate Change Impacts and Adaptation
January 8, 2010

ESA co-sponsored a congressional briefing that provided a scientific perspective on options for adapting to climate change in the United States.

Featured speakers:

  • Michael MacCracken, Chief Scientist for Climate Change Programs, the Climate Institute
  • Kristie L. Ebi, Executive Director, Intergovernmental Panel on Climate Change (IPCC) Working Group 2 Technical Support Unit - Impacts, Adaptation, and Vulnerability
  • Katherine L. Jacobs, Professor, University of Arizona Soil, Water and Environmental Science Department
  • Susanne Moser, Director and Principal Researcher, Susanne Moser Research & Consulting

Water Resources in the West: Assessing Tradeoffs in a Changing Climate

On July 13, 2009, ESA hosted House and Senate briefings, “Water Resources in the West: Assessing Tradeoffs in a Changing Climate,” featuring Society members: Jill Baron of the US Geological Survey and Colorado State University; Darrel Jenerette of the University of California, Riverside; and Diane Pataki of the University of California, Irvine. 

The ecological scientists provided information on the current status and future outlook for freshwater resources in the American West, where the impacts of climate change and agricultural and urban demand are most pronounced. Sharing insights from their work in urban, agricultural, and natural ecosystems, they discussed the implications of water management and conservation strategies, with an emphasis on the tradeoffs inherent to water allocation decisions.

Dr. Baron explained the drivers behind western water shortages, described the possible negative impacts of these shortages on natural freshwater ecosystems, and discussed how such impacts might be lessened through adaptive ecosystem management.

Dr. Jenerette discussed how water allocation decisions impact the availability of ecosystem resources and how ecological research can assist in decision-making .

Dr. Pataki focused on urban ecology, explaining how existing landscaping decisions—including some “green” initiatives—can reduce water efficiency. Giving the example of tree planting projects, Pataki demonstrated the importance of considering ecological factors, such as the types of tree species planted, in making land-use decisions.

The two briefings drew more than 100 attendees in total, including congressional staff and researchers, federal agency representatives, and members of the scientific community.
