The Australian Community Climate and Earth System Simulator (ACCESS) is used by CSIRO, the Australian Bureau of Meteorology and Australian universities to produce weather forecasts and climate projections. ACCESS has been recently extended to include land and ocean carbon cycle components in its Earth System Model (ESM) version, ACCESS-ESM1. Here we analyse the results from ACCESS-ESM1 historical simulations including their validation against independent estimates and future projections using representative concentration pathways (RCPs). The main focus of the analysis is on carbon related variables. We also explore the carbon-concentration and carbon-climate feedbacks by performing idealized simulations, where atmospheric CO2 levels are increased at a prescribed rate of 1%/yr.
