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.

生物多样性丧失和气候变化的综合严重性不断加大。由于即将到来的灾难看起来从未如此令人震惊，有关生物气候危机的科学知识仍在呈指数级增长。在这里，我们反思生态学或气候科学的研究人员在这场危机中的表现。面对科学家知道多少与他们参与多少之间的不成比例，我们讨论了可能导致科学意识与具体行动脱钩的四个障碍。然后，我们反思理性思维本身引发参与的潜力，并质疑更多的科学知识是否可以成为社会彻底变革的转折点。我们的观察挑战了这样一个原则：更好地了解我们周围的事物对于有效地保护它是必要的。由于科学研究本身的环境成本是必须考虑的额外因素，我们建议研究人员迫切需要集体反思自己的处境并决定如何调整自己的行动方向。
