Increases in Arctic Extreme Climatic Events Are Linked to Negative Fitness Effects on the Local Biota.

ABSTRACT: The Arctic harbours uniquely adapted biodiversity and plays an important role in climate regulation. Strong warming trends in the terrestrial Arctic have been linked to an increase in aboveground biomass (Arctic greening) and community-wide shifts such as the northwards-expansion of boreal species (borealization). Whilst considerable efforts have been made to understand the effects of warming trends in average temperatures on Arctic biota, far fewer studies have focused on trends in extreme climate events and their biotic effects, which have been suggested to be particularly impactful during the Arctic winter months. Here, we present an analysis of trends in two ecologically relevant winter extreme events-extreme winter warming and rain-on-snow-followed by a meta-analysis on the evidence b
