2014 AAAS Symposium - “Santa’s Revenge: The Impacts of Arctic Warming on the Mid-Latitudes”

This event was spearheaded by the U.S. National Committee for Geodesy and Geophysics, and co-sponsored by the U.S. National Committees for INQUA, Soil Sciences, and Geological Sciences. The symposium examined high-latitude changes linked to mid-latitude weather and the effect of these complex phenomena on freshwater resources, food availability, and national security. Speakers included: 

  • Mark Serreze (National Snow and Ice Data Center, University of Colorado-Boulder): “Impacts on Arctic Pack Ice Predictions of Extreme Weather and Natural Variability”
  • James Overland (NOAA/Pacific Marine Environmental Laboratory): “When Will the Summer Arctic be Nearly Sea Ice-Free?
  • Jennifer Francis (Rutgers University): “Evidence Linking Arctic Amplification with Changing Weather Patterns in Mid-Latitudes”
  • Jerry Hatfield (Iowa State University/USDA-Agricultural Research Service): “Agriculture Impacts and Impacts on International Food Supplies and Prices”
  • David Titley (Pennsylvania State University): “Impact of a Warming Arctic on National Security”

Organizer: Michael MacCracken, Climate Institute
Co-Organizers: Ester Sztein, National Academy of Sciences; and Robin Muench, Earth and Space Research
Discussant: Hajo Eicken, University of Alaska
