This talk focuses on key scientific questions concerning surface processes and climate feedbacks within the Earth system, centered around the fundamental question: how hot can the greenhouse Earth become? It systematically examines the response mechanisms and predictability of the climate system.
By integrating multi-source observations with Earth system model simulations, the talk reveals the large-scale responses of global vegetation change and its multi-scale feedbacks to the climate system. Particular emphasis is placed on the critical role of landโatmosphere interactions in regulating the water cycle and surface energy balance. The presentation further evaluates systematic biases in current climate models in representing these feedback processes and discusses pathways for improvement based on observational constraints and process understanding. Finally, it addresses the long-term sustainability of negative vegetation feedbacks and the potential for tipping points, providing scientific insights for understanding future climate change and informing mitigation strategies.
