  • Direct human impact on land disturbances in the USA is declining, while less controllable, undirected wild disturbances are increasing, according to a long-term record of high-resolution satellite imagery.

  • Remote sensing often detects higher vegetation greenness for croplands than for forests, despite forests having a greater leaf area. This study shows that this is an artefact of shadows caused by forest structures and explores how to correct for this when interpreting global vegetation change data.

  • Cloud cover and scarcity of ground-based validation hinder remote sensing of forest dynamics in the Amazon basin. Here, the authors analyse imagery from a high-frequency geostationary satellite sensor to study monthly NDVI patterns in the Amazon forest, finding support for spatially extensive seasonality.

  • Since the early 1980s, remotely sensed data has shown the Earth to be slowly greening. Climate change, CO2 fertilization and land-use change are competing explanations. Using satellite data from 2000–2017, this study finds striking greening of both China and India, driven primarily by land-use change, with forest growth and cropland intensification more important in China and cropland more important in India.

  • Satellite-derived leaf area and survey-based agricultural data indicate that dry season irrigation contributes to India’s greening, however land surface models struggle to accurately reproduce the greening trend and its drivers.

  • Vegetation on Earth is increasing, potentially leading to a larger terrestrial carbon sink. In this Review, we discuss the occurrence of this global greening phenomenon, its drivers and how it might impact carbon cycling and land-atmosphere heat and water fluxes.
