Abstract. We present SURFER, a model for sea level rise that consists of three sub-models: an updated and expanded version of BEAM carbon cycle model (Glotter et al., 2014), a 2-box climate model that allows for solar radiation management and a simple ice sheet model that represents the tipping points and related timescales of Greenland and Antarctic ice sheets. The model, consisting of 8 ordinary differential equations, is fast, accurate up to timescales of several thousands of years and has been calibrated to reproduce results obtained by state of the art carbon cycle and ice sheet models. Additionally the ice sheet sub-model has been written in a flexible way that allows easily updating its parameters to match future results.

Short summary
SURFER is a lightweight model that links CO2 emissions to ocean acidification and sea level rise. It consists of three sub-models: a carbon cycle model, a climate model with the possibility of geoengineering and an ice sheet model. The ice sheet model adequately describes the tipping points of both Greenland and Antarctica. SURFER is fast, accurate up to several thousands of years, capable of emulating results obtained by complex state of the art models and well suited for policy analyses.
