Sequential Climate Change Policy, Edward A. Parson, Darshan Karwat
Sequential Climate Change Policy, Edward A. Parson, Darshan Karwat
Articles
Successfully managing global climate change will require a process of sequential, or iterative, decision‐making, whereby policies and other decisions are revised repeatedly over multiple decades in response to changes in scientific knowledge, technological capabilities, or other conditions. Sequential decisions are required by the combined presence of long lags and uncertainty in climate and energy systems. Climate decision studies have most often examined simple cases of sequential decisions, with two decision points at fixed times and initial uncertainties that are resolved at the second decision point. Studies using this formulation initially suggested that increasing uncertainty favors stronger immediate action, while the …
Useful Global-Change Scenarios: Current Issues And Challenges, Edward A. Parson
Useful Global-Change Scenarios: Current Issues And Challenges, Edward A. Parson
Articles
Scenarios are increasingly used to inform global-change debates, but their connection to decisions has been weak and indirect. This reflects the greater number and variety of potential users and scenario needs, relative to other decision domains where scenario use is more established. Global-change scenario needs include common elements, e.g., model-generated projections of emissions and climate change, needed by many users but in different ways and with different assumptions. For these common elements, the limited ability to engage diverse global-change users in scenario development requires extreme transparency in communicating underlying reasoning and assumptions, including probability judgments. Other scenario needs are specific …
Reflections On Air Capture: The Political Economy Of Active Intervention In The Global Environment; An Editorial Comment, Edward A. Parson
Reflections On Air Capture: The Political Economy Of Active Intervention In The Global Environment; An Editorial Comment, Edward A. Parson
Articles
When global climate change came onto domestic and international policy agendas in the late 1980s, only two types of response were initially considered: reducing emissions by improving efficiencies or switching to lower or non-carbon energy sources; and adapting to the anticipated changes. Since that time the agenda of potential responses has been progressively expanded, principally by adding various ways to intervene in the global carbon cycle or the climate to break the connection between emissions of greenhouse gases and the resultant climate changes. Three types of these “intervening” responses are now, to varying degrees, present in policy debate: biological sequestration …
Preparing For Climatic Change: The Water, Salmon, And Forests Of The Pacific Northwest, Philip W. Mote, Edward A. Parson, Alan F. Hamlet, William S. Keeton, Dennis Lettenmaier, Nathan Mantua, Edward L. Miles, David W. Peterson, David L. Peterson, Richard Slaughter, Amy K. Snover

The impacts of year-to-year and decade-to-decade climatic variations on some of the Pacific Northwest’s key natural resources can be quantified to estimate sensitivity to regional climatic changes expected as part of anthropogenic global climatic change. Warmer, drier years, often associated with El Niño events and/or the warm phase of the Pacific Decadal Oscillation, tend to be associated with below-average snowpack, streamflow, and flood risk, below-average salmon survival, below-average forest growth, and above-average risk of forest fire. During the 20th century, the region experienced a warming of 0.8 ◦C. Using output from eight climate models, we project a further warming of …
Understanding Climatic Impacts, Vulnerabilities, And Adaptation In The United States: Building A Capacity For Assessment, Edward A. Parson, Robert W. Corell, Eric J.

Based on the experience of the U.S. National Assessment, we propose a program of research and analysis to advance capability for assessment of climate impacts, vulnerabilities, and adaptation options. We identify specific priorities for scientific research on the responses of ecological and socioeconomic systems to climate and other stresses; for improvement in the climatic inputs to impact assessments; and for further development of assessment methods to improve their practical utility to decision-makers. Finally, we propose a new institutional model for assessment, based principally on regional efforts that integrate observations, research, data, applications, and assessment on climate and linked environmental-change issues. …
