Evolution of the Earth Climate history among 2 different tipping dynamical landscapes and proposal for a potential third one. The first dynamical landscape, in light red, corresponds to the Hot-Warm House time interval. The second one, in light blue, represents the Cold-Ice house time interval. The third one, in light green, highlights the potential new dynamical landscape represented by the Anthropocene time interval. The different abrupt transitions identified in the present study are reported as TPos or RTPos to differentiate the major tipping points from the critical transitions characterizing transitions of lighter significance in the climate history. Various plate tectonic and ice sheet events are indicated and supported by maps of plate movements and North and South Hemisphere ice sheets. The Antarctica maps are from Pollard & DeConto79, Northern Hemisphere ice sheet maps are from Batchelor et al.80. The paleogeographic maps have been generated using the Ocean Drilling Stratigraphic Network (ODSN) plate tectonic reconstruction service: < https://www.odsn.de/odsn/services/paleomap/paleomap.html > . The red arrows on the tectonic maps indicate the key events that correspond to abrupt transition.
