What is TipESM?

TipESM is a project funded by the European Union Horizon Europe Funding Programme. The project started on 1 January 2024 and will run until 31 December 2027.

TipESM is coordinated by the Danish Meteorological Institute with Dr. Shuting Yang (sy@dmi.dk) as the Project Coordinator.

What do we do?

TipESM brings together scientists from a range of disciplines to deliver a step change in our understanding of climate tipping points in the Earth system, including their impact on ecosystems and society, combined with a set of early warning indicators and safe future emission pathways that minimise the risk of exceeding such tipping points.

TipESM assembles the latest Earth System Models (ESMs), including recent improvements to key processes: ice sheets, vegetation and land use, permafrost, marine and terrestrial biogeochemistry. In cooperation with the WCRP/Future-Earth project TIPMIP, TipESM will organise an international collaboration to design and realise a common ESM experiment protocol that will facilitate analysis of the likelihood of occurrence, and potential reversibility, of tipping elements at different levels and duration of global warming. These experiments, will be combined with more project-specific ESM experiments, designed to investigate interactions and feedbacks across the Earth system. 

Based on the TipESM experiments, existing simulations and observations, we will investigate tipping points, their driving processes, potential early warning signals and cascading effects across the climate, ecosystems and society. Including the most important components of the Earth system in our ESMs will also allow TipESM to identify potentially unknown tipping elements, their precursors and impacts.

How do we work?

TipESM brings together expertise from climate science and climate impacts to investigate both the role of gradual climate change for tipping in individual ecosystems and society, and the impact of crossing specific climate tipping points for society, ecosystems, and biodiversity. Project findings will be synthesised into a tipping points risk register. 

New knowledge and data from TipESM will be regularly communicated to a broad range of research communities, policymakers and the public, contributing to a prepared and resilient society.

Science Themes

TipESM is organised into a series of science themes implemented by the project Work Packages which set out achieve the primary objective of TipESM – to deliver a step change in our understanding of climate tipping points in the Earth system, including their impact on ecosystems and society, combined with a set of early warning indicators and safe emission pathways that minimise the risk of exceeding such tipping points.

1. To design and perform a set of coordinated experiments with coupled Earth system models to support the investigation of Earth system tipping points at different levels of global warming

Work Packages: 1, 2, 4 & 5

2. To identify climate tipping points in the CMIP6 archive and dedicated runs from TipESM and previous EU projects, and improve our understanding of the processes underpinning such tipping points and their impact across the Earth system

Work packages: 1 & 2

3. To investigate the robustness and potential (ir)reversibility of climate tipping points

Work packages: 1 & 3

4. To identify precursors of climate and ecological tipping points, and develop reliable early warning indicators based on Earth system models and observations

Work packages: 1, 4, 5 & 6

5. To identify the risk of a cascade from one climate tipping event to others

Work packages: 1, 5, 6 & 7

6. To identify tipping events in ecological and societal systems, with a focus on the climate-drivers of these events, emphasising biodiversity, human health and habitability

Work packages: 1, 3 & 6

7. To provide new understanding on the climate, societal and ecosystem consequences of crossing climate thresholds and tipping points

Work packages: 1, 7 & 8

8. To deliver a risk register of future tipping points and a set of safe emission pathways to minimise the chance of crossing such tipping points through engagement with stakeholders and by feeding tailored information to adaptation strategies via ClimateAdapt and European Environmental Agency, European Climate and Health Observatory, ECDC, UN Office for Disaster Risk Reduction (UNDDR), UNEP

Work packages: 1, 2, 3, 4, 5, 6, 7, 8, 9 & 10

9. To provide policy guidance to the European Commission, IPCC, IPBES and the UNFCC Global Stocktake, on the likelihood and consequences of crossing climate tipping points and mitigation options to minimise the chance of such events

Work packages: 1, 2, 3, 4, 5, 6, 7, 8, 9 & 10

Expected Impacts

TipESM delivers a unique contribution to the climate research landscape through advancing our knowledge on the risk of climate Tipping Points and their potential impact on ecological systems and society.
