A review of water use in the U.S. electric power sector: insights from systems-level perspectives
(JOURNAL) [Published : Aug 14, 2014]
Thermoelectric power production comprised 41% of total freshwater withdrawals in the U.S., surpassing even agriculture. This review highlights scenarios of the electric sector’s future demands for water, including scenarios that limit both CO2 and water availability. A number o...
NexGen PVAs: Incorporating Eco-Evolutionary Processes into Population Viability Models
(JOURNAL) [Published : Dec 11, 2014]
We examine how the integration of evolutionary and ecological processes in population dynamics – an emerging framework in ecology – could be incorporated into population viability analysis (PVA). Driven by parallel, complementary advances in population genomics and computational ...

Developing a model for effects of climate change on human health and health-environment interactions: Heat stress in Austin, Texas - Urban Climate
(JOURNAL) [Published : Jun 05, 2014]
Human health and well-being are and will be affected by climate change, both directly through changes in extreme weather events and indirectly through weather-induced changes in human and natural systems. Populations are vulnerable to these changes in varying degrees, depending ...
Multiple Adaptation Types with Mitigation: A Framework for Policy Analysis
(JOURNAL) [Published : Dec 11, 2013]
Effective climate policy will consist of mitigation and adaptation implemented simultaneously in a policy portfolio to reduce the risks of climate change. The relative share of these responses will vary over time and will be adjusted in response to new information. Furthermore,...
Long-range climate impacts on crop yield and the implications of enacting global carbon mitigation policies
(JOURNAL)
Research on climate impacts and agriculture over the past two decades has applied simulation models at a range of scales and future climate scenarios, finding that crop growth and yield responds to changing climate conditions, and that the impacts are regional and highly depende...
Climate change risks to United States infrastructure: impacts on coastal development, roads, bridges, and urban drainage
(JOURNAL) [Published : Apr 01, 2014]
Changes in temperature, precipitation, sea level, and coastal storms will likely increase the vulnerability of infrastructure across the United States. Using four models of vulnerability, impacts, and adaptation of infrastructure, its deployment, and its role in protecting econom...
Climate change impacts on extreme temperature mortality in select metropolitan areas of the United States
(JOURNAL) [Published : Jul 10, 2014]
Projected mortality from climate change-driven impacts on extremely hot and cold days increases significantly over the 21st century in a large group of United States Metropolitan Statistical Areas. Increases in projected mortality from more hot days are greater than decreases in ...
Overview of the Special Issue: A Multi-Model Framework to Achieve Consistent Evaluation of Climate Change Impacts in the United States
(JOURNAL) [Published : Sep 16, 2014]
The Climate Change Impacts and Risk Analysis (CIRA) project establishes a new multi-model framework to systematically assess the impacts, economic damages, and risks from climate change in the United States. The primary goal of this framework to estimate how climate change impac...
Calibrated Methodology for Assessing Adaptation Costs for Urban Drainage Systems
(JOURNAL)
Changes in precipitation patterns associated with climate change may pose significant challenges for storm water management systems across much of the U.S. In particular, adapting these systems to more intense rainfall events will require significant investment. The assessment ...
Assessment of Climate Change Adaptation Costs for the U.S. Road Network
(JOURNAL)
The U.S. road network is one of the nation’s most important capital assets and is vital to the functioning of the U.S. economy. Climate change may represent a risk or an opportunity to this network, as changes in climate stress will affect the resources necessary for both road m...
Marine nitrous oxide emissions: An unknown liability for the international water sector
(JOURNAL) [Published : Nov 01, 2013]
Reliable estimates of anthropogenic greenhouse gas (GHG) emissions are essential for setting effective climate policy at both the sector and national level. Current IPCC Guidelines for calculating nitrous oxide (N2O) emissions from sewage management are both highly uncertain and ...
A Systems Perspective on Responses to Climate Change
(JOURNAL) [Published : Apr 01, 2014]
The science of climate change integrates many scientific fields to explain and predict the complex effects of greenhouse gas concentrations on the planet’s energy balance, weather patterns, and ecosystems as well as economic and social systems. A changing climate requires respons...
Toward Quantitative Analysis of Water-Energy-Urban-Climate Nexus for Urban Adaptation Planning
(JOURNAL) [Published : Aug 01, 2014]
Water and energy are two interwoven factors affecting environmental management and urban development planning. Meanwhile, rapid urban development and a changing climate exacerbate the magnitude and effects of water-energy interactions in what nexus defines. These factors and th...
Impacts Of Human Alteration Of The Nitrogen Cycle In The Us On Radiative Forcing
(JOURNAL) [Published : Sep 01, 2012]
Will address mitigation, adaptation, and impacts of climate-N interactions.
