Scientists Meet Scientists – TUM-IAS Wednesday Coffee Talk “Destabilizing Earth System Components” by Niklas Boers
Events, WCT |

On 17 December 2025, Niklas Boers (Earth System Modelling, TUM) will talk about “Destabilizing Earth System Components”.
Abstract: There is rising concern that several parts of the Earth system may abruptly transition to alternative stable states in response to anthropogenic climate and land-use change. Key candidates of such tipping elements include the Greenland Ice Sheet, the Atlantic Meridional Overturning Circulation, the South American monsoon system and the Amazon rainforest. The levels of anthropogenic forcing at which transitions to alternative states can be expected remain uncertain. In this talk I present observation-based evidence that the stability of these four tipping elements has declined in recent decades, suggesting that they have moved towards their critical thresholds, which may be crossed within the range of unmitigated anthropogenic warming. Our results call for better monitoring of these tipping elements and for increased efforts to stop greenhouse gas emissions and land-use change.

THE TUM-IAS WEDNESDAY COFFEE TALKS
Every Wednesday after lunch, it's all about a new topic - current research highlights at TUM, insights into the work of our Fellows from all over the world, sometimes even topics not usually found at TUM, such as history or theology.
The talks held online start every Wednesday during TUM lecture time at 13:00 CE(S)T. Everyone is welcome - TUM researchers of all levels, students, visiting scholars, and anyone interested!
