These patterns emerge consistently in both managed and intact forests, corroborating the existence of common large-scale climate drivers. By contrast, boreal forests show divergent local patterns with an average increasing trend in resilience, probably benefiting from warming and CO 2 fertilization, which may outweigh the adverse effects of climate change. We show that tropical, arid and temperate forests are experiencing a significant decline in resilience, probably related to increased water limitations and climate variability. Here we integrate satellite-based vegetation indices with machine learning to show how forest resilience, quantified in terms of critical slowing down indicators 3, 4, 5, has changed during the period 2000–2020. Experimental evidence of sudden increases in tree mortality is raising concerns about variation in forest resilience 2, yet little is known about how it is evolving in response to climate change. The LEAR also provided information on the levels of employment and deprivation correlating to the building by building assessment in each area.Forest ecosystems depend on their capacity to withstand and recover from natural and anthropogenic perturbations (that is, their resilience) 1.
