About the Tsukuba Conference Session

The role of historical astronomy is becoming increasingly important in predicting future environmental changes. Over thousands of years, astronomical records have contributed to climate change research by elucidating solar activity cycles through observations of sunspots and the solar corona, as well as analyzing their connections to extreme weather events. In this session, experts on astronomical records from various regions will introduce the characteristics of their respective records and examples of data utilization. Furthermore, from the perspectives of solar physics and digital humanities, we will discuss methods for integrating historical records with the latest scientific technologies to improve the accuracy of future solar activity and extreme weather predictions. By exploring new possibilities for applying historical astronomical knowledge, this session aims to contribute to disaster risk reduction worldwide, including in the Global South.
