Climate Change Adaptation and Environmental Engineering:
Evolving Practices and New Tools
The climate is changing globally and across the U.S., with different types and extent of change in different regions. Observed changes include sustained deviation from long-term trends in atmospheric temperatures, water temperatures, precipitation amounts, drought duration, storm frequency, wind velocities, snow melt timing, flood frequency and characteristics, permafrost melting, and other phenomena. These changes are affecting civil and environmental infrastructure and leading to demand for modification of infrastructure designs and operations. New approaches are needed in infrastructure design and operation guidelines, codes, and procedures to account for changing climate conditions.
New tools are coming into use in infrastructure engineering for projection of changing climate conditions, especially downscaled global climate model (GCM) products. Depending on the type of engineering application and purpose of required future climate information, various climate model projections are being applied and utilized, with different temporal and spatial resolution, type of downscaled GCM products employed, and post-processing methods for calibration of the results to regional and local scale.
This talk will examine the need and challenge of climate change projection in particular locations, the scale at which infrastructure engineering projects take place. Evolving practices and tools will be presented, and demonstrated through some environmental engineering applications. The use of climate projection results from several different GCMs and downscaled products and from an ensemble of multiple GCMs will be explored in the context of the applications. The importance and utility of historical long-term observations for particular locations will also be examined. Opportunities to access, learn about, and exploit these new tools for environmental engineering will be discussed.
Is It Achievable and Can Environmental Engineering Help Get Us There?
Extraction and processing of fuel and non-fuel minerals from the Earth has a plethora of impacts on land, water, air and ecosystems. Reduction and remediation of these impacts long has engaged environmental engineers in research and practice. Application of sustainability principles to mining is inherently challenging, considering the impacts involved and that mining involves removal of finite resources. However, as demand continues for fuel minerals such as coal and non-fuel minerals such as metals, consideration of environmental sustainability is increasingly being incorporated into development and operation of mines.
This talk will examine the environmental sustainability profiles of fuel and non-fuel mineral mining, and efforts that have been undertaken over the past 30 years to improve these profiles. The talk will focus on coal and copper mining in the U.S. as important examples of fuel- and non-fuel mineral mining. Current and evolving mining industry practices and related environmental engineering activities will be reviewed. Approaches for assessing the environmental sustainability of mining operations will be presented and applied to the two cases, with consideration of scale from operations at individual sites to system level.
The meaning of sustainable mining will be explored, as will the potential to achieve sustainable mining for fuel and non-fuel minerals. A framework for assessment of sustainability in mining that includes life-cycle metrics will be put forward. Application of the framework to copper will be presented as an example. The role of environmental engineers in advancing the environmental sustainability of mining will be examined with the audience.
