  1. warm cold -- ~ Humans Time [~4600 – 0 Ma] ~ Terr. Vegetation Proterozoic Precambrian

  2. Inland ice from Vostok (Antarctica) -> biospheric influence on CO2 (photosynthesis) and CH4 (anaerobic decomposition of organic material) Petit et al. 1999

  3. Simulation of glacial inception Calov et al.

  4. Pre-ind. surface cond. Eemian surface cond. Atm.+ oce.+veg. Atm.+ oce. Atm.+ veg. Atm.  Vegetation: snow-albedo feedback (in addition to oceanic sea ice-albedo feedback)

  5. (Cowling)

  6. Reconstruction of climate maps for certain time slices (6000 years BP:Cheddadi et al., Clim. Dyn., 1997) Temperature coldest month Temperature sum Water availability Precipitation - evaporation

  7. > 5oC Reconstruction of local time series (here: last glacial inception)

  8. Grape harvest

  9. Modern vegetation from pollen analysis LGM reconstructed vegetation
