    The Arctic is dotted with lakes, including thermokarst lakes highly threatened by climate change. Here, the authors investigate 35 years of lake drainage events and related vegetation trends across the Arctic, finding differences between thermokarst and non-thermokarst lake drainage events.

    Tree growth in boreal forests is generally predicted to increase under warming. Here, the authors demonstrate a method to analyze physiologically informed temperature series of tree-ring data, finding potentially overlooked growth-temperature responses and projecting increasing risks of warming to boreal larch forests.

    Defoliating insects disrupt nutrient cycling of boreal catchments by redistributing carbon and nitrogen from forests to lakes. The resulting shift in lake biogeochemistry exceeds broader between-year trends observed across the boreal and north temperate region.

    A primary element of modern wildfire management is to aggressively suppress small fires before they become large, but benefits can be offset by the fact that these practices promote older forests that are more ‘flammable’. Here the authors show that this downside puts numerous human communities at elevated risk of fires in boreal Canada.

    Understanding mechanisms of soil organic matter (SOM) decomposition and stabilisation improves soil-climate feedback predictions. Here the authors show that roots in boreal forest promote organic nitrogen economy and provide a framework on how roots affect decomposition and stabilisation of SOM.

    Northern tree populations may not benefit under climate change, with implications for assisted migration and range expansion. Here, Isaac-Renton et al. show that leading-edge lodgepole pine populations have fewer characteristics of drought-tolerance, so may not adapt to tolerate drier conditions.

    Future permafrost thaw may be underestimated unless effects of wildfire are considered. Here the authors show that wildfires in boreal permafrost peatlands influence soil temperature and seasonal thaw depth for several decades, and increase the rate of complete permafrost thaw along permafrost edges.

    The role of ecosystem structure in microbial activity related to greenhouse gas production is poorly understood. Here, Taş and colleagues show that microbial communities and ecosystem function vary across fine-scale topography in a polygonal tundra.

    Recent increases in the dissolved organic carbon (DOC) content of northern aquatic systems are likely to lead to increases in CO2 emissions, yet the mechanisms are poorly understood. Here, evidence from hundreds of Canadian aquatic systems suggests a causal link between DOC concentrations and CO2flux.
