The main objective of the nine papers from Topical Collection “Impact Attribution: Exploring the contribution of climate change to recent trends in hydrological processes” published in Climatic Change (https://link.springer.com/collections/bibbfajfea) was to attribute existing trends to climate change where possible and applying observational and counterfactual climate data as input. For this purpose, 97 river basins in Europe, Asia and Africa were selected and analysed.
In 42% of the investigated river basins, changes of precipitation could be attributed to climate change. Interestingly, a positive trend in streamflow could be seen in Norway, northern Russia, northern Kazakhstan, western China and in the Lake Victoria basin. Negative trends in streamflow attributable to climate change were detected in the Blue Nile and Main Nile, in three basins of Central and South Asia and in the Selenga river basin.
