Content Summary | In order to study the future of freshwater availability, reliable precipitation projections are required. Potential
future changes in global precipitation are investigated by analyzing the Global Climate Models’ projections. However,
these projections cannot be used in their native form on climate change impact studies, due to the high systematic
errors and biases that they feature, limiting the applicability of these projections. Various methodologies have been
developed to correct the precipitation bias, including dynamical and statistical methods. Here we present a global
precipitation ensemble projection for the 21st century. We use a multi-segment statistical bias correction method that
radically reduces the correction-induced uncertainty to the precipitation. The ensemble consist of results from three
different global climate models for A2 and B1 emission scenarios, in order to reduce the uncertainty related to the model
selection. The results show significant changes in areal mean and extreme precipitation during the 21st century for the
A2 and B1 emission scenarios. For all simulations, the results show that the global mean and extreme precipitation will
increase under both scenarios, indicating a more intense forthcoming global water cycle. | en |
