Аннотация: <jats:title>Abstract</jats:title> <jats:p>Although recent warming affects the high-northern latitudes at an unprecedented rate, little is known about its impact on boreal forests because <jats:italic>in situ</jats:italic> observations from remote ecosystems in Siberia are sparse. Here, we analyse the radial growth and climate sensiПоказать полностьюtivity of 54 Cajander larches (<jats:italic>Larix cajanderi</jats:italic> Mayr.) from three sites across the northern treeline ecotone within the Omoloy river basin in northeastern Siberia. Three independent tree-ring width chronologies span 279–499 years and exhibit distinct summer temperature signals. These records further reveal evidence for sufficiently earlier onsets of growing seasons since the middle of the 20th century. This phenological shift coincides with rapidly increasing May temperatures and associated earlier snowmelt. Our findings reinforce the importance of high-precision ground measurements from remote regions in Siberia to better understand how warming-induced changes in the functioning and productivity of the boreal forest influence carbon, nutrient, and water cycle dynamics.</jats:p>
