The Tipping Points Modelling Intercomparison Project (TIPMIP)

TIPMIP is an international intercomparison project that aims to systematically advance our understanding of tipping dynamics in various Earth system components, and assess the associated uncertainties. By connecting and evaluating various models, TIPMIP will fill critical knowledge gaps in Earth system and climate modelling by improving the assessment of overall anthropogenic forcing and long-term commitments (irreversibilities). It will furthermore foster interdisciplinary knowledge transfer and shed light on critical processes currently underrepresented in Earth-system models and analysis.

Register for the TIPMIP for All Webinars!

Join us for one of the two TIPMIP for All Q&A sessions to be held on 18. Nov. 2025 at 09:00 CET and 17:00 CET!

At these webinars, we will offer a very brief overview of TIPMIP (including recent updates) for those unfamiliar, but primarily we see them as an “open-office” hour where colleagues can ask questions and receive feedback from the team and other members of the community.

You must register in advance, either for Session 1 (09:00 – 10:00 CET), or for Session 2.) (17:00 – 18:00 CET).

To submit your questions in advance, please complete this short questionnaire.

Recordings of the webinar will be made and published afterwards on the TIPMIP website.

TIPMIP General Assembly 2024 in Baltimore

Maryland (USA) has more than 3100 miles of tidal shoreline, making it one of the most vulnerable U.S. states to global sea level rise. Further sea level rise induced by tipping in the Antarctic and Greenland ice sheets presents a serious threat to the city’s resilience. The Baltimore’s Inner Harbor served as a fitting backdrop for the second TIPMIP General Assembly, held there from 4.-7. December of 2024.

In Baltimore, scientific sessions highlighted first results from the TIPMIP experiments as well as synergies with previous community modeling efforts across the various Earth systems of interest. Highlights included a keynote from U.S. Senator and Senate Budget Committee then-Chairman Sheldon Whitehouse on the critical importance of TIPMIP and tipping points research broadly. The following evening, participants gathered in the IMAX theatre of the Maryland Science Center to view films from Open Planet Studios highlighting tipping points and equity, followed by discussion.
