global change
Earth-wide transformation process
Global change refers to large-scale transformations affecting the entire planet, particularly alterations in climate, ecosystems, and biogeochemical cycles.
The term encompasses climate change but is broader, including shifts in land use, biodiversity loss, and changes in atmospheric composition: Global change research examines how human activities alter Earth's systems.
Scientists increasingly prefer this term when discussing interconnected planetary changes rather than climate alone.
