Climate change is one of the major threats to biodiversity at present. Species are expected to migrate, evolve, persist locally or go extinct in response to climate change, but after decades of research we are still struggling to predict which response(s) will be more likely across different taxa, whether species will be able to adapt or migrate at the required pace, or which taxa may be at higher risk of extinction. This puzzling situation is partly due to the inherent complexity and limited understanding of the processes involved, and to the scarcity of appropriate comparative data. However, climate has been changing incessantly along Earth’s history: how did species respond to past climate changes? How much migration, extinction, persistence and extinction occurred, and which factors (if any) could explain the outcome in retrospect? How do biotic interactions affect species responses? Looking backwards can be a fruitful way to increase our understanding and hopefully improve our predictive ability. This symposium will seek answers to these pressing questions by investigating biodiversity responses to past climate changes. In particular, this symposium has three main aims: (i) provide a synthesis of current knowledge about biodiversity responses to past climate changes; (ii) highlight current unknowns and propose ways to expand our knowledge, and (iii) discuss how this retrospective knowledge can be used rigorously to improve forecasts of climate change impacts for the next decades.
