  1. The Climate of the Last 2000 Years AOS 528, 12/04/07

  2. The Last 2000 Years • Multiple proxy records mixed with instrumental data • Proxies: • Ice Cores • Tree Rings • Historical Documents • Records almost entirely land-based prior to the instrumental record

  3. Locations of Proxies Records

  4. Proxy NH Temperature Data Reconstructions

  5. Regional: Global Medieval Warm Period?

  6. Climate Models

  7. Climate Models: NH Temperature Results NH Simulations: With and Without Anthro Forcings Climate Models: Forcings Used

  8. Global Warming Now 2006

  9. Headed for another record? 2007
