We find the reliability of predictions of distributional shifts of plankton made by commonly used ‘species distribution models’ to be worse than is commonly appreciated.

In this study we thoroughly tested the predictive skill of species distribution models for copepods, diatoms and dinoflagellates. Species distribution models are the standard tool to project the relocation of species under future climate change. Our conclusions are based on model-predictions up to 50 years into the future and past that we then tested directly against observations from one of the longest-running marine observational datasets. Predictions of plankton distributions are important to understand and adapt to climate change impacts, but need to be evaluated critically.
