Past Warm Periods Informing the Anthropocene
Convenors
Stijn De Schepper, Bjørg Risebrobakken, Bette Otto-Bliesner, Stéphanie Desprat.
Description
Global climate predictions indicate that by the end of this century global temperature will have risen to levels unprecedented during instrumental times. Studies of past warm periods throughout Earth's history are key to understand Earth system dynamics and the natural variability of the climate system in a globally warmer world. For this session, we solicit data and model contributions investigating ocean, land, atmosphere and cryosphere interactions during past warm climates. We welcome contributions from each past warm period that can provide insights into the present and future state of Earth's climate.
