Climate Change, Climate Variability, and Decision-Making

Forecasts of both climate change and climate variability-the latter entailing variation at the intra-annual, annual, or decadal scales–pose problems for decision making because of their inherent uncertainty. While strong scientific evidence of upcoming changes exist both for long-term secular change and heightened variability, this evidence gets milled together with institutional practices, political pressures, and decision heuristics that suffuse both public and private decision-making. My research in this area aims to enhance our understanding of the grinder mill to support more efficacious interventions.

Note that in an attempt to honor the confusing spirit of copyright law, I’ve not uploaded PDFs of my papers to this page, but

  • I provide pointers to most of the publishers’ websites, which typically provides at least access to each paper’s abstract
  • I’ve made most of these available as full text through and
  • I’m happy to send PDFs attachments to individuals under the fair use doctrine, so contact me via email if interested
