 Human-made global warming can lead to a destabilisation of large-scale components of the Earth system such as the large polar ice sheets, ocean circulation patterns or global biosphere components. These Earth subsystems are the so-called climate tipping elements [[#ref1|[1]]].
-Recently, the risk of destabilising one or several tipping elements have been assessed as a consequence of overshooting global warming levels of 1.5 °C [2]. The analyses show how crucial it is for the state of the planet to adhere to the climate objectives of the Paris Agreement, and emphasises the legacy of our climate (in)action today for centuries to millennia to come.

-While transgressing thresholds in the physical climate system are assessed to pose severe risks for the stability of the biosphere and human societies, social tipping processes may have the potential to initiate a swift transition towards sustainability keeping our physical climate system intact [3].

-Summarized, this presentation will provide an overview on tipping elements in the Earth’s climate system, their current state and potentially stabilizing positive social tipping dynamics, as assessed in the Global Tipping Points Report 2023 for COP28 [4].
