SPRING 2023 UPDATE: CliC is no longer able to support the wiki, hence the "deprecated messages" at the top of these pages. However, ISMIP6 and its follow-on activities have a new wiki hosted on Ghub. The information on the CliC Wiki has been updated and migrated to Ghub. Please come and see our [https://theghub.org/groups/ismip6/wiki/MainPage new wiki]!

Current effort: ISMIP6 Antarctic 2300 projections. These projections focus on simulations of the Antarctic Ice Sheet extended to year 2300. These new experiments were launched in February 2022 and more details are available [https://www.climate-cryosphere.org/wiki/index.php?title=ISMIP6-Projections2300-Antarctica here] and on the Ghub  [https://theghub.org/groups/ismip6/wiki/ISMIP6-Projections2300-Antarctica ISMIP6 wiki].

The overall framework for ISMIP6 is designed to deliver projections of the ice sheet contribution to sea level rise. ISMIP6 brings together for the first time a consortium of international ice sheet models and coupled ice sheet – climate models. This effort will thoroughly explore the sea level contribution from the Greenland and Antarctic Ice Sheet in our changing climate and assess the impact of large ice sheets on the climate system. Together with the new glacier [http://www.climate-cryosphere.org/activities/targeted/ismip6 CliC] (Climate and Cryosphere) targeted activity and projections of thermal expansion (that already sit within the [https://en.wikipedia.org/wiki/Coupled_model_intercomparison_project CMIP] Coupled Model Intercomparison Project framework), this will allow sea level to become part of the family of variables for which CMIP can provide routine IPCC-style projections. ISMIP6 is explicitly designed to ensure that ice sheet (hence sea level) projections are fully compatible with the CMIP6 (Coupled Model Intercomparison Project-Phase 6) process. ISMIP6 also provides the basis for investigating the feedbacks, impacts, and sea level changes associated with dynamic ice sheets and for quantifying the uncertainty in ice-sheet-sourced global sea level change.

The proposed [http://www.geosci-model-dev.net/9/4521/2016/gmd-9-4521-2016.pdf experiments] will both use and augment the CMIP6-DECK (Diagnostic Evaluation and Characetization of Klima), Historical and ScenarioMIP experiments, as summarized in the table below. ISMIP6 will use the standard CMIP [https://en.wikipedia.org/wiki/General_circulation_model AGCM] (Atmosphere General Circulation Models) and [https://en.wikipedia.org/wiki/General_circulation_model AOGCM] (Atmosphere-Ocean General Circulation Models) experiments for analysis of the climate over and surrounding the ice sheets, and as forcing for the standalone ice sheet models (ISM) projections. Additional sensitivity experiments will be performed with the ISM to investigate the uncertainty associated with these projections arising from ice sheet models. The key output will be an ensemble of historical and future estimates of ice sheet contribution to sea level. To address the feedbacks introduced by interactive ice sheets, we propose that a small number of selected DECK experiments are repeated with coupled AOGCM-ISM, where the ice sheet is an interactive component of the AOGCM. Our assessment of the state of existing AOGCMs is that coupled models including an interactive Greenland ice sheet can realistically be expected for CMIP6, however including the Antarctic ice sheet remains challenging (because of the greater complexity of its response to climate forcing, and the issues associated with simulations of the Southern Ocean). It is for these reasons that [http://www.geosci-model-dev.net/9/4521/2016/gmd-9-4521-2016.pdf ISMIP6] heavily relies on standalone ice sheet models driven offline by CMIP6 climate models for projections of sea level.

'''[[ISMIP6 Standalone Ice Sheet Experiments]]''' > These [http://www.climate-cryosphere.org/wiki/index.php?title=ISMIP6_Standalone_Ice_Sheet_Experiments pages] describe the experimental setup for the standalone ice sheet model simulations. ISMIP6 standalone ice sheet modeling focusses on gaining insight into the uncertainty in ice sheet evolution resulting from the choice of initialization methods (the initMIP efforts for the Greenland and Antarctic ice sheets),  understanding the response of the Antarctic ice sheet to a total loss of the ice shelves (ABUMIP), as well as projections of ice sheet evolution for the 21st century.

Welcome to the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6) wiki! You are encouraged to use the wiki pages to alter the formulation of numerical experiments, point out any inconsistencies or inaccuracies you find in the data sets, and post results and figures that you'd like others see and discuss. ISMIP6 also has a more official homepage, kindly hosted by CliC.

SPRING 2023 UPDATE: CliC is no longer able to support the wiki, hence the "deprecated messages" at the top of these pages. However, ISMIP6 and its follow-on activities have a new wiki hosted on Ghub. The information on the CliC Wiki has been updated and migrated to Ghub. Please come and see our new wiki!

Current effort: ISMIP6 Antarctic 2300 projections. These projections focus on simulations of the Antarctic Ice Sheet extended to year 2300. These new experiments were launched in February 2022 and more details are available here and on the Ghub ISMIP6 wiki.

What is ISMIP6?

The overall framework for ISMIP6 is designed to deliver projections of the ice sheet contribution to sea level rise. ISMIP6 brings together for the first time a consortium of international ice sheet models and coupled ice sheet – climate models. This effort thoroughly explores the sea level contribution from the Greenland and Antarctic Ice Sheet in our changing climate and assess the impact of large ice sheets on the climate system. Together with the new glacier CliC (Climate and Cryosphere) targeted activity and projections of thermal expansion (that already sit within the CMIP Coupled Model Intercomparison Project framework), this allows sea level to become part of the family of variables for which CMIP can provide routine IPCC-style projections. ISMIP6 is explicitly designed to ensure that ice sheet (hence sea level) projections are fully compatible with the CMIP6 (Coupled Model Intercomparison Project-Phase 6) process. ISMIP6 also provides the basis for investigating the feedbacks, impacts, and sea level changes associated with dynamic ice sheets and for quantifying the uncertainty in ice-sheet-sourced global sea level change.


The proposed experiments both use and augment the CMIP6-DECK (Diagnostic Evaluation and Characetization of Klima), Historical and ScenarioMIP experiments. ISMIP6 uses the standard CMIP AGCM (Atmosphere General Circulation Models) and AOGCM (Atmosphere-Ocean General Circulation Models) experiments for analysis of the climate over and surrounding the ice sheets, and as forcing for the standalone ice sheet models (ISM) projections. Additional sensitivity experiments were performed with the ISM to investigate the uncertainty associated with these projections arising from ice sheet models. The key output is an ensemble of historical and future estimates of ice sheet contribution to sea level. To address the feedbacks introduced by interactive ice sheets, we proposed that a small number of selected DECK experiments are repeated with coupled AOGCM-ISM, where the ice sheet is an interactive component of the AOGCM. Our assessment of the state of existing AOGCMs is that coupled models including an interactive Greenland ice sheet can realistically be expected for CMIP6, however including the Antarctic ice sheet remains challenging (because of the greater complexity of its response to climate forcing, and the issues associated with simulations of the Southern Ocean). It is for these reasons that ISMIP6 heavily relies on standalone ice sheet models driven offline by CMIP6 climate models for projections of sea level.
