Over the past 66 million years, two major climate events have shaped the climate system, dividing the period into two distinct climate eras. An analysis of the hierarchy of tipping points indicates that over the past 66 million years, two significant occurrences laid the foundation for subsequent c
A new study uses the theory of punctuated equilibrium to analyze the hierarchy of climate tipping points, identifying two major events in the last 66 million years that have set the stage for Earth’s current and future climate. The researchers warn that if anthropogenic climate change leads to complete deglaciation, it would be a landmark tipping point affecting Earth’s climate on a geological timescale.
The research, conducted by Denis-Didier Rousseau from Université Montpellier, France, Witold Bagniewski from Ecole Normale Supérieure, Paris, France, and Valerio Lucarini from the University of Reading, UK, was published in the journalInspired by a theory of evolution The results indeed suggest that the idea of hierarchies in the evolution of the climate system can lead to new insights. The analysis reveals that two major events out of the ten dominated the evolution of the Earth’s climate system over the last 66 million years.The first event was the Chicxulub meteor impact in Mexico which killed off the large dinosaurs approximately 65,5 million years ago. This catastrophe marked the beginning of a very warm period with high levels of CO2.
