The mass loss of glaciers and ice caps is one of the major contributors to sea-level rise over the past 120 years. Different climate forcings, both natural and anthropogenic, have an influence on the climate and therefore on glacier mass balance. Glaciers have a slow and delayed response to climate change, and at any point in time, their properties are therefore also a result of past climate changes. In this context, we present global glacier simulations over the last millennium. For these simulations, the Open Global Glacier Model was forced with the fully forced, single forced and control simulations of the Community Earth System Model Last Millennium Ensemble. These simulations show how different climate forcings, i.e., volcanic, greenhouse gasses, solar, orbital, land use & land cover and ozone-aerosol, impact the climatic mass balance, both individually and combined. These influences are then analyzed over time and regionally. In addition to addressing the role of the different forcings, we present the contribution of natural vs anthropogenic forcings on glacier mass balance over the last millennium.
