Presentation Transcript

  1. Paleocene-Eocene Thermal Maximum(PETM) 55 Million Years Ago

  2. PETM 50 Million Years Ago

  3. Short duration of between 1,000 and 10,000 years • Time of higher CO2(large error bars)

  4. PETM Event • Warming at all latitudes • Warming in both surface and deep oceans • Warmth lasted approximately 100kyr

  5. Oxygen isotopes indicate a global warming event similar to or greater than 21st Century forecasts (+5°C) Carbon isotopes indicate a rapid influx of lightweight carbon (methane release? carbon dioxide?)
