Across various disciplines, a number of community-wide initiatives (such as GSWP, ISIMIP, HAPPI, ILAMB, etc.) have developed to synthesize and advance knowledge of climate change impacts, land surface processes, and global energy and water cycles. They have achieved significant scientific progress and made indispensable contributions to the development of Earth system sciences in recent decades. Now, there is a growing need to exchange and collaborate between these different initiatives and disciplines, in order to solve, in particular, emerging problems related to climate and human society as a holistic system. This symposium and workshop will provide a forum to strengthen synergies between climate monitoring, modeling, and impact research communities and to discuss how to deliver scientific achievements to our society. Early career scientists and researchers from developing countries are welcome to join. A particular scientific focus of the meeting will be on climate extremes and their impacts, acknowledging the importance of these events in a changing climate.
