Aspen Global Change Institute: 25 Years of Interdisciplinary Global Change Science

Global environmental changes such as climate change result from the interaction of human and natural systems. Research to understand these changes and options for addressing them requires the physical, environmental, and social sciences, as well as engineering and other applied fields. In this essay, we describe how the Aspen Global Change Institute (AGCI) has provided leadership in global change science over the past 25 years—in particular how it has contributed to the integration of the natural and social sciences needed to research the drivers of change, Earth system response, natural and human system impacts, and options for risk management. We illustrate the ways the history of AGCI has been intertwined with the evolution of global change science as it has become an increasingly interdisciplinary endeavor.

The FEMP Awards Program: Fostering Institutional Change and Energy Management Excellence

This report assesses the use of institutional change principles and the institutional impact of award-winning projects through interviews with 22 Department of Energy Federal Energy Management Program (DOE FEMP) award winners. Award winners identified institutional facilitators and barriers in their projects and programs as well as factors in their implementation processes, thus providing information that can guide other efforts. We found that award winners do use strategies based on eight principles of institutional change, most frequently in terms of making changes to infrastructure, engaging leadership, and capitalizing on multiple motivations for making an energy efficiency improvement. The principles drawn on the least often were commitment and social empowerment. Award winners also faced five major types of obstacles that were institutional in nature: lack of resources, constraints of rules, psychological barriers, lack of information, and communication problems. We also used the seven categories of Energy Management Excellence (EME) as a lens to interpret the interview data and assess whether these categories relate to established institutional change principles. We found that the eight principles reflect strategies that have been found to be useful in improving energy efficiency in organizations, whereas the EME categories capture more of a blend of social contextual factors and strategies. The EME categories fill in some of the social context gaps that facilitate institutional change and energy management excellence, for example, personal persistence, a culture that supports creativity and innovation, regular engagement with tenants, contractors, and staff at all levels. Taking together the use of principles, EME criteria, and obstacles faced by interviewees, we make recommendations for how FEMP can better foster institutional change in federal agencies.

Behavioral Change and Building Performance: Strategies for Significant, Persistent, and Measurable Institutional Change

The people who use Federal buildings — Federal employees, operations and maintenance staff, and the general public — can significantly impact a building’s environmental performance and the consumption of energy, water, and materials. Many factors influence building occupants’ use of resources (use behaviors) including work process requirements, ability to fulfill agency missions, new and possibly unfamiliar high-efficiency/high-performance building technologies; a lack of understanding, education, and training; inaccessible information or ineffective feedback mechanisms; and cultural norms and institutional rules and requirements, among others. While many strategies have been used to introduce new occupant use behaviors that promote sustainability and reduced resource consumption, few have been verified in the scientific literature or have properly documented case study results. This paper documents validated strategies that have been shown to encourage new use behaviors that can result in significant, persistent, and measureable reductions in resource consumption. From the peer-reviewed literature, the paper identifies relevant strategies for Federal facilities and commercial buildings that focus on the individual, groups of individuals (e.g., work groups), and institutions — their policies, requirements, and culture. The paper documents methods with evidence of success in changing use behaviors and enabling occupants to effectively interact with new technologies/designs. It also provides a case study of the strategies used at a Federal facility — Fort Carson, Colorado. The paper documents gaps in the current literature and approaches, and provides topics for future research.

Changing Institutional Procurement Behavior to Achieve Energy Savings

Although federal policies regarding energy-efficient product procurement (EEPP) are long-standing and well-established, federal buyers do not typically request energy-efficient products when making purchases. This is a large missed opportunity: full compliance could save the U.S. federal government roughly $500 million in energy cost annually. In 2016, the U.S. Department of Energy’s Federal Energy Management Program (FEMP) began a new set of program activities to increase federal compliance with these procurement requirements. Program interventions included increased communication with contracting officers during the solicitation process; development of enhanced, targeted training; and collection and dissemination of procurement best practices across the federal sector. We have collected and analyzed ~2,500 solicitations from over 40 different federal agencies to evaluate the influence of these interventions. Compared to pre-intervention years (FY15 and FY11), annual compliance rates for FY16 and FY17 increased by about 10%. This paper provides an overview of the data collection process, analysis framework, intervention method, and results of our analysis. We discuss strategies to increase compliance rates by examining institutional factors that drive procurement behavior. By combining data collection with adjustment to program implementation, we have created an iterative process that is having a demonstrable effect in improving the impact of a long-running program.

Oak Ridge Site Specific Advisory Board Adapts To Engage - 16459

Environmental Management (EM) Site Specific Advisory Boards (SSABs) are representative of their communities and exist for the purpose of advising DOE EM. As such they are the conduits between the public and the DOE EM. To remain relevant to the community they cannot exist in a vacuum and the public needs to be aware of the Boards' function, purpose, and progress and have opportunities for input. Since the SSABs generally deal with fairly complex issues related to environmental cleanup, and the members of the Boards represent a diversity of background, there are many challenges associated with informing and eliciting input from Board members as well as informing and engaging the public. To that end, Oak Ridge SSAB (ORSSAB) has instituted changes to facilitate Board and public engagement. As the ORSSAB has matured and the work has become routine, it has become a challenge to keep members interested and invested. So the Board asks its members to provide input on how to make the process better. Through our annual member surveys and facilitated meetings, we query the board for ideas, and the results of these surveys and meetings are discussed at the annual planning meetings. Agreed changes are instituted in the following year. Recently the ORSSAB has instituted positive changes in the meeting structure, locations, and content. There are fewer formal meetings and these meetings are shorter. The board has also incorporated field trips to specific sites prior to presentations on those areas to further enhance membership understanding of the problems at hand, site conditions, and enormity and scope of the work to be undertaken. Changes of meeting location have occurred. Instead of the standard meeting room, the ORSSAB has met at local restaurants (in private rooms) where food service is available, and the atmosphere is more relaxed and informal. This gives members an opportunity to interact with each other rather than sitting in designated places at a formal meeting with video cameras rolling. Not only are the members more at ease, the presenters are more relaxed in their response to questions. Open discussion sessions have also been added to the meeting agendas. The ORSSAB participates in both public outreach and public engagement. Public outreach activities have included: presentations to local citizens groups; televising meetings on public access cable channels in three local communities; publishing The Advocate, a quarterly newsletter; and recently setting up and maintaining a Facebook page. Activities related to public engagement included the Board's participation at a DOE-sponsored community budget workshop. The ORSSAB strives for value and relevancy, attempting to convey a clear message to the community and to DOE. It also strives to inform its membership in a way that allows for clarity of understanding, and above all it tries to be enjoyable to its membership. The ORSSAB listens to its membership and has evolved its process to allow for effective advocacy. (authors)

Addressing trend-related changes within cumulative effects studies in water resources planning

Summarized herein are 28 case studies wherein trend-related causative physical, social, or institutional changes were connected to consequential changes in runoff, water quality, and riparian and aquatic ecological features. The reviewed cases were systematically evaluated relative to their identified environmental effects; usage of analytical frameworks, and appropriate models, methods, and technologies; and the attention given to mitigation and/or management of the resultant causative and consequential changes. These changes also represent important considerations in project design and operation, and in cumulative effects studies associated therewith. The cases were grouped into five categories: institutional changes associated with legislation and policies (seven cases); physical changes from land use changes in urbanizing watersheds (eight cases); physical changes from land use changes and development projects in watersheds (four cases); physical, institutional, and social changes from land use and related policy changes in river basins (three cases); and multiple changes within a comprehensive study of land use and policy changes in the Willamette River Basin in Oregon (six cases). A tabulation of 110 models, methods and technologies used in the studies is also presented. General observations from this review were that the features were unique for each case; the consequential changes were logically based on the causative changes; the analytical frameworks provided relevant structures for the studies, and the identified methods and technologies were pertinent for addressing both the causative and consequential changes. One key lesson was that the cases provide useful, “real-world” illustrations of the importance of addressing trend-related changes in cumulative effects studies within water resources planning. Accordingly, they could be used as an “initial tool kit” for addressing trend-related changes.

The Role of Awards Programs in Stimulating Energy Efficient Behavior: A Study of Award Winners

The value of formal awards programs may be principally in gaining wider recognition for achievements in energy efficiency. But how do these programs contribute to the goal that is presumably behind this value, i.e., stimulating further energy efficient behavior, beyond publicizing the awards ceremonies and describing the projects via websites, posters, and the like? Interviews with 22 individuals and teams of award winners under the Department of Energy Federal Energy Management Program (DOE FEMP) yield insights on the roles that awards programs can play in stimulating energy efficient behavior, especially with regard to institutional dimensions of such behavior. Award winners identified institutional facilitators and barriers in their projects and programs as well as factors in their implementation processes, thus providing information that can guide other efforts. Although only one of the interviewees affirmed that winning an award was a motivating factor, awards do validate often-hard-won achievements through recognition and, in some cases, additional resources, thus stimulating both the winners themselves and those who see the achievements to further energy-saving activities. Finally, award winners’ responses demonstrated the importance of behavioral and institutional change in energy efficiency.

Cloud feedback studies with a physics grid

This project was funded by DOE in 2007 but work was initially delayed, first because a senior investigator on the original project (Stephen Thomas) took another position, and subsequently because the PI changed institutions, leaving UCLA in the summer of 2008 to join the MPI-M in Hamburg Germany. The project was moved to the MPI-M with the help of DOE staff, and after negotiating numerous logistical and administrative hurdles the project started in April 2010. Due to differences in funding the project funding was able to support roughly three person years, and our institution also agreed to supplement the support to fund the main postdoc for a third year. Due to the change of institutions, and considerable development in dynamical cores since the initiation of the project it was decided to work through the ideas using the new ICON dynamical core. The ICON dynamical core is based on a icosahedral grid and serves a prototype for dynamical cores that are being developed in a number of institutions, including at NCAR (the so called MPAS model) for a future version of the Community Earth System Model. The advantage of using ICON for these purposes is that the the ICON dynamical core is relatively stable, and is built on a hierarchical concept that naturally adapts itself to the proposed experimental strategy. Using ICON also allows the project to benefit from staff at the institute who have helped develop ICON, thus bring the main ideas more rapidly to fruition. However, because of the on-going development in the very core of the model and other issues related to pre and post processing, the project did not end in the expected manner. Although the plans in the proposed project has been achieved, to run the heterogeneous multiscale model at global scale requires very heavy computing resources which was not expected. We have found some encouraging results using the available resources on a smaller domain and we plan to investigate them further on a larger scale in near future.

Midwestern Regional Center of the Doe National Institute for Climatic Change Research

The goal of NICCR (National Institute for Climatic Change Research) was to mobilize university researchers, from all regions of the country, in support of the climatic change research objectives of DOE/BER. The NICCR Midwestern Regional Center (MRC) supported work in the following states: North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Minnesota, Iowa, Missouri, Wisconsin, Illinois, Michigan, Indiana, and Ohio. The MRC of NICCR was able to support nearly $\$ $8 million in climatic change research, including $\$ $6,671,303 for twenty projects solicited and selected by the MRC over five requests for proposals (RFPs) and $\$ $1,051,666 for the final year of ten projects from the discontinued DOE NIGEC (National Institute for Global Environmental Change) program. The projects selected and funded by the MRC resulted in 135 peer-reviewed publications and supported the training of 25 PhD students and 23 Masters students. Another 36 publications were generated by the final year of continuing NIGEC projects supported by the MRC. The projects funded by the MRC used a variety of approaches to answer questions relevant to the DOE’s climate change research program. These included experiments that manipulated temperature, moisture and other global change factors; studies that sought to understand how the distribution of species and ecosystems might change under future climates; studies that used measurements and modeling to examine current ecosystem fluxes of energy and mass and those that would exist under future conditions; and studies that synthesized existing data sets to improve our understanding of the effects of climatic change on terrestrial ecosystems. In all of these efforts, the MRC specifically sought to identify and quantify responses of terrestrial ecosystems that were not well understood or not well modeled by current efforts. The MRC also sought to better understand and model important feedbacks between terrestrial ecosystems, atmospheric chemistry, and regional and global climate systems. The broad variety of projects the MRC has supported gave us a unique opportunity to greatly improve our ability to predict the future health, composition and function of important agricultural and natural terrestrial ecosystems within the Midwestern Region.

Next Generation Climate Change Experiments Needed to Advance Knowledge and for Assessment of CMIP6

The Aspen Global Change Institute hosted a technical science workshop entitled, “Next generation climate change experiments needed to advance knowledge and for assessment of CMIP6,” on August 4-9, 2013 in Aspen, CO. Jerry Meehl (NCAR), Richard Moss (PNNL), and Karl Taylor (LLNL) served as co-chairs for the workshop which included the participation of 32 scientists representing most of the major climate modeling centers for a total of 160 participant days. In August 2013, AGCI gathered a high level meeting of representatives from major climate modeling centers around the world to assess achievements and lessons learned from the most recent generation of coordinated modeling experiments known as the Coupled Model Intercomparison Project – 5 (CMIP5) as well as to scope out the science questions and coordination structure desired for the next anticipated phase of modeling experiments called CMIP6. The workshop allowed for reflection on the coordination of the CMIP5 process as well as intercomparison of model results, such as were assessed in the most recent IPCC 5th Assessment Report, Working Group 1. For example, this slide from Masahiro Watanabe examines performance on a range of models capturing Atlantic Meridional Overturning Circulation (AMOC).

Understanding spatial and temporal drivers of variation in tree hydraulic processes and their consequences for climate feedbacks (Final Technical Report)

This is the final technical report from the first phase of a project that changed institutions. The grant was titled “Understanding spatial and temporal drivers of variation in tree hydraulic processes and their consequences for climate feedbacks.” The overall objectives of this project were to (1) provide model‐compatible datasets of key plant hydraulic traits and status for model evaluation, parameterization and validation and (2) use these data to pinpoint ecosystem responses to a changing hydroclimate by addressing both long‐term climatic drying and episodic extreme droughts. We planned to address the objectives with three research activities to quantify plant responses to chronic water stress and episodic drought: (1) generate high frequency observations of soil and plant hydraulic data across different landscape positions at multiple sites, (2) quantify plant hydraulic trait plasticity in response to experimental soil moisture reduction in situ in two central hardwood forests, and (3) simulate the carbon consequences of incorporating plant hydrodynamics and plant acclimation to water stress in the DOE‐sponsored plant hydrodynamics model FATES‐HYDRO. As of the transfer of this project to another institution, we had made substantial progress on activities 1 and 2, and started activity 3.

Interdisciplinary Workshop on the Impacts of Land Use and Land Management on Earth System Evolution, Biogeochemical Cycles, Extremes, and Inter-Sectoral Dynamics (Final Report)

The Aspen Global Change Institute (AGCI) convened a week-long interdisciplinary science workshop from September 15-20, 2019 entitled, “Impacts of Land Use and Land Management on Earth System Evolution, Biogeochemical Cycles, Extremes, and Inter-Sectoral Dynamics.” The purpose of the workshop was to advance research on the impacts of land use and land management on climate, carbon emissions, and extremes, as well as the impact of land-use change on important societal issues such as food, water, and energy security. The workshop was co-chaired by Kate Calvin (PNNL), George Hurtt (University of Maryland), and Dave Lawrence (National Center for Atmospheric Research). Co-funders of the workshop included NASA, NOAA, and travel support for European colleagues through CRESCENDO. This workshop brought together 31 professionals with expertise across biogeochemistry, climate impacts, mitigation, land use datasets, and societal impacts to coordinate on upcoming research and publications on the role of biogeochemical and biophysical properties of the Earth surface and their implications for climate, as conducted through the Land Use model Intercomparison Project (LUMIP), which is part of Phase 6 of the Coupled Model Intercomparison Project (CMIP6). A primary outcome of the meeting was the definition and planning of a series of LUMIP papers that will rely on the LUMIP and CMIP6 simulations. By the end of the meeting more than twenty papers and paper lead authors had been identified and scoped out. Around ten of these papers were submitted by the December 31, 2019 IPCC deadline.
