A reassessment of the relationship between growth and climate suggests that Eurasian boreal larch forests may be at risk of decline. However, the impact of climate change on the region's forests is complex, with some areas potentially experiencing increased tree species diversity due to global warming, while others may be negatively affected by extreme conditions. The southern margin of the Eurasian boreal forest may be approaching a thermal tipping point, further complicating the outlook for the region's forests.
