    • Are global wind power resource estimates overstated? 

      Adams, Amanda S.; Keith, David (IOP Publishing, 2013)
      Estimates of the global wind power resource over land range from 56 to 400 TW. Most estimates have implicitly assumed that extraction of wind energy does not alter large-scale winds enough to significantly limit wind power ...

    • Can we test geoengineering? 

      MacMynowski, Douglas G.; Keith, David; Caldeira, Ken; Shin, Ho-Jeong (Royal Society of Chemistry (RSC), 2011)
      Solar radiation management (SRM), a form of geoengineering, might be used to offset some fraction of the anthropogenic radiative forcing of climate as a means to reduce climate change, but the risks and effectiveness of ...

    • Climatic Impacts of Wind Power 

      Miller, Lee; Keith, David (Elsevier BV, 2018-12)
      Wind power can impact the climate by altering the atmospheric boundary layer, with at least 40 papers and 10 observational studies now linking wind power to climatic impacts. We make the first comparison between the climatic ...

    • Compressed air energy storage with waste heat export: An Alberta case study 

      Safaei, Hossein; Keith, David (Elsevier BV, 2014)
      Interest in compressed air energy storage (CAES) technology has been renewed driven by the need to manage variability form rapidly growing wind and solar capacity. Distributed CAES (D-CAES) design aims to improve the ...

    • Cost Analysis of Stratospheric Albedo Modification Delivery Systems 

      McClellan, Justin; Keith, David; Apt, Jay (IOP Publishing, 2012)
      We perform engineering cost analyses of systems capable of delivering 1–5 million metric tonnes (Mt) of albedo modification material to altitudes of 18–30 km. The goal is to compare a range of delivery systems evaluated ...

    • Effectiveness of stratospheric solar-radiation management as a function of climate sensitivity 

      Ricke, Katharine L.; Rowlands, Daniel J.; Ingram, William J.; Keith, David; Granger Morgan, M. (Nature Publishing Group, 2011)
      If implementation of proposals to engineer the climate through solar-radiation management (SRM) ever occurs, it is likely to be contingent on climate sensitivity. However, modelling studies examining the effectiveness of ...

    • The Fate of an Engineered Planet 

      Keith, David; Parker, Andy (Nature Publishing Group, 2013)
      Solar engineering and other exceptionally ambitious new technologies to deal with the reality of rising global temperatures come riddled with uncertainties. To illustrate how complex the problem is and what kind of challenges ...

    • Field experiments on solar geoengineering: report of a workshop exploring a representative research portfolio 

      Keith, David W.; Duren, Riley; MacMartin, Douglas G. (The Royal Society Publishing, 2014)
      We summarize a portfolio of possible field experiments on solar radiation management (SRM) and related technologies. The portfolio is intended to support analysis of potential field research related to SRM including ...

    • Geoengineering: The world's largest control problem 

      MacMartin, Douglas G.; Kravitz, Ben; Keith, David (IEEE, 2014)
      Solar geoengineering (or Solar Radiation Management, SRM) refers to any intentional, large-scale manipulation of the Earth's incoming solar radiation to offset some of the effects of anthropogenic greenhouse gases, reducing ...

    • Liability for Solar Geoengineering: Historical Precedents, Contemporary Innovations, and Governance Possibilities 

      Horton, Joshua; Parker, Andrew Richard; Keith, David (2015)

    • A multi-model assessment of regional climate disparities caused by solar geoengineering 

      Kravitz, Ben; MacMartin, Douglas G; Robock, Alan; Rasch, Philip J; Ricke, Katharine L; Cole, Jason N S; Curry, Charles L; Irvine, Peter J; Ji, Duoying; Keith, David; Egill Kristjánsson, Jón; Moore, John C; Muri, Helene; Singh, Balwinder; Tilmes, Simone; Watanabe, Shingo; Yang, Shuting; Yoon, Jin-Ho (IOP Publishing, 2014)
      Global-scale solar geoengineering is the deliberate modification of the climate system to offset some amount of anthropogenic climate change by reducing the amount of incident solar radiation at the surface. These changes ...

    • Not a Superpower 

      Keith, David (Institute for Research on Public Policy, 2014)
      Clean energy innovation cannot be left to the market alone, nor can it be achieved by governments that dodge hard decisions by spreading funds to all. Winning the clean-energy innovation game requires industry and government ...

    • Public understanding of solar radiation management 

      Mercer, A M; Keith, David; Sharp, J D (IOP Publishing, 2011)
      We report the results of the first large-scale international survey of public perception of geoengineering and solar radiation management (SRM). Our sample of 3105 individuals in the United States, Canada and the United ...

    • Stratospheric controlled perturbation experiment: a small-scale experiment to improve understanding of the risks of solar geoengineering 

      Dykema, John A.; Keith, David W.; Anderson, James G.; Weisenstein, Debra (The Royal Society Publishing, 2014)
      Although solar radiation management (SRM) through stratospheric aerosol methods has the potential to mitigate impacts of climate change, our current knowledge of stratospheric processes suggests that these methods may ...
