Coupled Model Intercomparison Project (CMIP6)

Fachgebiet: Klimatologie, Modellierung

Projektleitung: Prof. Dr. Julia Pongratz
Projektwissenschaftler: Dr. Felix Havermann, Prof. Dr. Julia Pongratz

Laufzeit: 04/2018 - 12/2025

The Coupled Model Intercomparison Project, now in phase 6 (CMIP6) is an international endeavor to better understand past, present and future climate changes under the auspices of the World Climate Research Programme (WCRP).

The project's key questions address:

- The Earth system's response to forcing
- The origins and relevance of systematic model biases
- Predictability and variability of future climate change

    Typically, several dozen Earth System Models world-wide run CMIP simulations. Results from CMIP simulations are a key component in the projections of climate change, of biogeochemical cycles, and of how well models perform as compared to observations that are assessed by the Intergovernmental Panel on Climate Change's (IPCC) Assessment Reports.

    The project's core are 26 CMIP6-endorsed model intercomparison projects (MIPs) that focus on specific aspects of the Earth system. The group contributed a range of simulations to the MIPs and leads analyses. Julia Pongratz is on the steering committees of two MIPs:

    the Land Use MIP (LUMIP) aims to assess the effects of different land-use scenarios under different future climates, the potential of land management to mitigate climate, and a better understanding of fundamental model differences


    the Coupled Climate-Carbon Cycle MIP (C4MIP) aims to understand and quantify future (century-scale) changes in the global carbon cycle and its feedbacks on the climate system, making the link between CO2 emissions and climate change.
