Researchers at the University of Tsukuba estimated Japan's spring leaf flush dates in recent years using data from the Second-generation Global Imager (SGLI) sensor onboard the Japan Aerospace Exploration Agency's (JAXA) Global Change Observation Mission-Climate (GCOM-C) satellite. Their analysis revealed that in 2023 and 2024, years characterized by exceptionally high spring temperatures, leaf flush occurred significantly earlier than usual, indicating that elevated temperatures linked to climate change are affecting Japanese ecosystems.
