Scientist engagement and the knowledge-action gap.

Abstract

The combined gravity of biodiversity loss and climate change keeps increasing. As the approaching catastrophe has never looked so alarming, the amount of scientific knowledge about the bioclimatic crisis is still rising exponentially. Here we reflect on how researchers in ecology or climate science behave amid this crisis. In face of the disproportionality between how much scientists know and how little they engage, we discuss four barriers that may underlie the decoupling of scientific awareness from concrete action. We then reflect on the potency of rational thinking to trigger engagement on its own, and question whether more scientific knowledge can be the tipping point towards radical changes within society. Our observations challenge the tenet that a better understanding of what surrounds us is necessary to protect it efficiently. With the environmental cost of scientific research itself as an additional factor that must be considered, we suggest there is an urgent need for researchers to collectively reflect on their situation and decide how to redirect their actions.
