Science Center Objects

This work is interdisciplinary and would not be possible without the collaboration of colleagues and their respective institutions. Research funding over the years has been provided by 1) the U.S. Geological Survey's National Research Program (NRP), the Climate and Land Use Program (CLU), the Southwestern and Alaska Climate Science Center, the Western Mountain Initiative (WMI), and the Northern Rocky Mountain Science Center (NOROCK), 2) the National Science Foundation (NSF) Paleo Perspectives on Climate Change (P2C2), Geography and Spatial Sciences (GSS), and Division of Environmental Biology Programs (DEB), and 3) The National Oceanic and Atmospheric Administration (NOAA).

Recent Research Projects Include:

  • Assessing the risk of persistent drought using climate model simulations and paleoclimate data
  • Variability common to first leaf dates and snowpack in the western conterminous United States
  • Regional patterns and proximal causes of the recent snowpack decline in the Rocky Mountains
  • The continuum of hydroclimate variability in western North America during the last millennium
  • Climate change links fate of glaciers and an endemic alpine invertebrate
  • Climate-induced changes in lake ecosystem structure inferred from coupled neo- and paleo-ecological approaches
  • Little Bighorn Battlefield National Monument riparian forest demography: Hydroclimatic tree-establishment conditions and a search for “witness trees”
  • The unusual nature of recent snowpack declines in the North American Cordillera.
  • Climatic controls on the snowmelt hydrology of the northern Rocky Mountains, USA.
  • Northern Hemisphere modes of variability and the timing of spring across western North America
  • An 1800-year record of decadal-scale hydroclimatic variability in the upper Arkansas River basin from bristlecone pine.
  • Leveraging modern climatology to increase adaptive capacity across protected areas.
  • Climate Analysis Tools
