Developing Approaches to Terrestrial Paleoclimatology II
1:20-4:00 p.m., Radisson Metrodome, Regent Room

  • Keynote address at 3:00 p.m. by Greg Retallack, University of Oregon:
    An Unfortunate Series of Global Atmospheric Greenhouse Spikes

    Retallack will discuss research that revealed 13 greenhouse warming crises over the past 300 million years. Each had different magnitude and likely cause, but all involved climate systems pushed out of control. Implications of our current practice of "carbon squandering" and possibilities for another crisis will be explored.
