Tipping Points in the Earth System (TiPES)

Extremes, physical drivers and impacts
In this project our focus is to quantify causes, mechanisms and impacts of tipping points and associated extremes under future climate and abrupt forcing, with an emphasis on compound events over the Mediterranean region

Funded by the European Union Horizon 2020 Innovation Programme, TiPES is a consortium of more than 15 institutions across Europe. Bringing together different expertise from a wide range of scientific subjects, TiPES aims to provide new fundamental insights into tipping points at the global scale


Dynamical systems analysis: Using a recently-developed method (Faranda et al., 2020) we are able to quantify joint recurrences in the phase-space for two (or more) atmospheric variables. The extreme values of these joint recurrences are termed as ‘compound dynamical extremes’ and they reflect compound meteorological events (Faranda et al., 2020; De Luca et al., 2020).
