  • Ice sheet evolution

  • Ocean sedimentation

  • Sedimentation

  • Paleoclimate indicators (Proxy data)Ice layersOcean sedimentsCoral BandsTree rings

  • Coral bands

  • Plankton

  • Pollen (Palynology)

  • Tree rings (dendrochronolgy)

  • Vegetation types /fossils45 million year old Palm

  • dO18 record

  • Colder climates more 18O in deep ocean (less is snow or ice cores)

  • Ice core data

  • Ice layer dating

  • Vostok ice core data
