TL;DR: In this article, the authors analyzed circumpolar data from 37 Arctic and alpine sites in 9 countries, including 25 species, and ∼42,000 annual growth records from 1,821 individuals, and demonstrated that the sensitivity of shrub growth to climate was heterogeneous, with European sites showing greater summer temperature sensitivity than North American sites, and higher at sites with greater soil moisture and for taller shrubs (for example, alders and willows) growing at their northern or upper elevational range edges.

TL;DR: Biome-wide relationships between temperature, moisture and seven key plant functional traits across the tundra and over time show that community height increased with warming across all sites, whereas other traits lagged behind predicted rates of change.

TL;DR: In 2018, Central Europe experienced one of the most severe and long-lasting summer drought and heat wave ever recorded, which had a greater impact on forest ecosystems of Austria, Germany and Switzerland than the 2003 drought as discussed by the authors.

TL;DR: This study quantifies the drought of 2018 as a yet unprecedented event, outlines hotspots of drought-impacted areas in 2018 which should be given particular attention in follow-up studies, and provides valuable insights into the heterogeneous responses of the dominant European ecosystems to hotter drought.

TL;DR: It is concluded that classical transfer function quality statistics should be preferred over the erroneous application of EPS in the context of evaluating the suitability of dendrochronological data for climate reconstructions.
