Abstract Climate change reshapes forest biophysical effects, yet the impact direction and strength remain uncertain. Here we quantify the growing-season land surface temperature between forests and adjacent open land (∆LSTgs) and show contrasting temporal trends in ∆LSTgs across the globe during 2001–2023. Rising vapour pressure deficit (VPD) has emerged as the primary driver of these contrasting trends, surpassing other common climatic factors.

Abstract The relationship between landscape fragmentation and vegetation resilience is uncertain. Here we use multiple satellite-based tree cover data and vegetation indices to quantify the apparent effects of fragmentation on global forest resilience and potential mechanisms thereof. We measure fragmentation as edge density, patch density and mean patch area of tree cover patches, and measure resilience as one-lag temporal autocorrelation of vegetation indices.

1 BRIEF INTRODUCTION: WHAT ARE MICROCLIMATES AND WHY ARE THEY IMPORTANT? Microclimates refer to the local climate conditions that organisms and ecosystems are exposed to. In terrestrial ecosystems, microclimates often differ strongly from the macroclimate, that is, the climate representative of a large geographic region.
