 The paper argues that bias correction, BC, is often used in an invalid way in climate change impact studies, leading to increased agreement with observations but not necessarily providing a satisfactory physical justification. The authors propose that the most promising strategy for improved future global and regional circulation model simulations is the increase in model resolution to the convection permitting scale in combination with ensemble predictions, based on sophisticated approaches for ensemble perturbation. They advocate communicating the entire uncertainty range associated with climate change predictions, openly to stimulate a lively discussion on bias correction among the atmospheric and hydrological community, and end users of climate change impact studies.
