Successive extreme climatic events lead to immediate, large‐scale, and diverse responses from fish in the Arctic
Abstract The warming trend of the Arctic is punctuated by several record‐breaking warm years with very low sea ice concentrations. The nature and reversibility of marine ecosystem responses to these multiple extreme climatic events (ECEs) are poorly understood. Here, we investigate the ecological si...
